A couple of suggestions; Never use a meter as an ohm meter in a box with live power. switching back and forth between volts and ohms is guaranteed to lead to meter destruction the one time you get distracted and crossed up. The other thing you might consider; megohm resistance readings can be caused by skin resistance, or if its hot (and its always hot) leaning on the frame in a damp shirt and touching the meter lead can easily account for phantom resistance values in megohm ranges as your body becomes a resistance in parallel with what you are measuring.. Hold a meter lead in each hand and see what your meter reads. Enjoyed your video. Thanks.

[@briangc1972]

You mis diagnosed this one. We see these all the time in the SW desert. A bad condenser motor will cause the compressor to over amp and blow fuses. The CFM is turning too slowly and that results in the high head pressure, low superheat, freon is not condensing fully, bubbles in the freon lead to high super heat, etc. When compressors fail, they typically trip the breaker (short to ground). I can count on one hand how many bad compressors blew fuses instead of tripping breakers; twice in over 20 years..... When a CFM goes bad, you blow fuses. Bad CFM causes the compressor to have high amp draw, eventually (hours later) enough so to cause a fuse to blow. FYI: You should ALWAYS weigh in your freon charge so you will know for certain the the charge is correct; the correct amount is right there on that label... It is IMPOSSIBLE to CORRECTLY charge an empty system by the gauges when starting a new compressor; I've NEVER seen anyone get it right. Pump it out into a tank, weigh it. Recharge using a scale, works 100% right EVERY time! Bleeding out freon is a hack job. If you have a package unit on the ground like that, there is no excuse for not pumping it out and weighing in the new charge. Had you pumped it out and seen the charge was correct, then you would KNOW there is another problem.

I sold rhuud for many years, around 2013, 14 , started having a lot of txv issues, they would work fine for a year or two, then just stick closed. I remedied the problem by replacing the txvs with pistons sized for the capacity. No more problems. I kept asking my sales rep who else was having these issues and why. he didn't know why but others were having same issues and just replacing txvs, but having the stuck closed problem reoccur in a year or so after replacing them. Come to find out after a few years of this, that Copeland had changed the moisture control additive in their compressors and it was reacting with the txvs causing them to stick closed, I didn't notice any drop in performance before they just totally failed, but I'm sure it was happening but it didn't show up a problem until they just stuck totally closed. I see that unit you were working on is a 2016 model. I'm sure it had the very same problem at first failure , they froze up and got a lot of compressors from it. I warranted many. Txv sticks closed, unit freeze up, liquid refrigerant wash the oil from the bearing , bearing fail, rotor hit the stator, compressor shorted.

[@jeffhurckes190]

7 megohm resistance on 240v is something like 30 uA of leakage current. I suspect that you are seeing that much resistance just from your fingers touching the probes.

[@mikemarshall1394]

Did you notice how loose the left fuse seemed be when snapped into position. A loose fuse gets hot and will fail.

[@OcRefrig]

Yep , seen it a lot. Loose fuses in disconnects WILL cause problems. Allways make sure fuses snap into holders tightly.

[@newmoon54]

Yes, anytime I came across those fused disconnects I always went to the customer and advised replacing them while I was there which would eliminate any future blown fuse calls, especially with service call fees being more than $125 just to come by!

[@jameshohimer2542]

HVAC GUY: It might help some of the younger guys if you would say what you are testing for as you touch each point with the meter leads. Like: “ checking Line voltage”, “let’s look at fuse continuity”, “checking run winding resistance”, “ windings to ground testing”. Also, give them a feeling for your assessment of each reading….like: “looks good”, “that’s a little low”, “that is not what I expected…..this reading should be a lot higher.” , “looks like start winding is shorted to ground”,etc. This was so frustrating to me when I was young, working with my Father. He said nothing, just went to work doing this and that, without a word as to what or why he was doing what he was doing or how he felt about the results or the conclusions being reached during the process. Very discouraging to say the least! Plus....I could never seem to hold the light just where he wanted it!

Thanks

[@daniellundquest8252]

I wouldn’t ohm a fuse out with power still being sent through it. It’s a fast way to blow up the meter. I would shut the breaker to the unit off and test it at the disconnect instead of pulling them out and testing it. Or you can just go right to checking the load side for voltage or lack thereof

[@Begrateful2024]

Yea i know someones meter act up after doing that. The plastic fuse puller is fairly cheap i keep one in the bag.

[@nightone9720]

Get rid of those ECM motors abd throw 2 rescue motors in there. I hate ECM motors. The whole idea with them is to save energy which will save money but they don't tell you is how expensive they are to replace when they break. There goes all your saving right there.

[@jameslang9170]

Rescue motors don’t last a year.

[@apollorobb]

Don't put your fingers on the test lead when your testing ohms . When you lean on a grounded machine with a sweaty shirt you are creating a path to ground. And always test resistance between the Capacitor terminals and the case of the capacitor . ive seen caps test good capacitance wise yet have resistance to ground in the 100's of ohms

[@MrNebRebew]

Aren’t those suction filters only suppose to be in the system for a few days max?

[@rogerchar246]

For that unit Min circuit amps is 35 Min circuit breaker amps is 45 Max circuit breaker amps is 50

[@94blowncobra94]

30a fuses are too small. The name plate said 36a was minimum with no heat strip. 50a was max. I'd put the 50s in there, and correct that TXV issue so the new comp doesn't crap out from high superheat and overheating. Also, get rid of that suction filter if and when you replace the TXV. Keep up the good vids bro.

[@rodgraff1782]

He would have to replace the disconnect. Was probably wrong from the start always go with the maximum HACR listed on the nameplate and make sure it’s a dual element time delay fuse.

[@timmalan3741]

Curious what your head preasure would of been with that cabinet on. Maybe more air was being pulled through open cabinet instead of across condenser?

[@sgtrock3785]

I suspect with a suction line filter that it was an acid burnout. Did you change out the suction line filter? I would start there before swapping the TXV.

[@ibbriley399]

7 megohms is 7 million ohms. The current to ground through 7 million ohms would be the line voltage divided by 7 million or 240/7,000,000, hardly enough to blow a 30 amp fuse. Also you read 29 megohms to ground from one of the other compressor leads when all three should read essentially the same, if the windings are ok. Plus, 7 megohms is practically an open circuit. So something is wrong with one of your readings. There are many possible reasons for the blown fuse. Any other electrical component in the system could be causing your problem including capacitors, the condenser fan motor, or the fuse itself. Please don’t resent my comments. I’m just an electrician, and I don’t know diddly about your refrigeration cycle, but I do understand some electrical theory and ohm’s law…….actually current to ground would be half what I stated in my first sentence. The 240 volt transformer secondary usually has a grounded center tap, so the current to ground would be calculated at 120 volts rather than 240.

[@joebrown493]

You saved me having to post. All I could think was Ohm's Law.

[@awwaldo]

The 2nd or 3rd attempt at reading ohms to ground on the compressor at the compressor, it appeared that you were touching the probe with your finger. That will give you a reading to ground through your body if you are grounded which it did. Now to watch the rest of the video to see what you finally found. 😁

What size is the circuit breaker in the house? I bet it's a 40. Replace the fuses with a standard disconnect, and replace the 10 gauge Romex with 8 gauge stranded.

[@throttlebottle5906]

the unit says 36 amps minimum circuit rating for single circuit no heat kit, the compressor and both fan motors total (29.7amps) going by the rating plate, that's greater than the fuses can withstand for any length of time, but that's also too much current for the wiring feeding the unit (10awg orange romex) in the whip, the disconnect is likely fed with the same undersized wiring. not sure what the installed heat strips installed are setup nor the circuit size feeding them, but maybe the circuits can be swapped and work out(maybe reversed when unit was replaced or they oversized it from existing?

[@mskimmel59]

Ever think about getting a megohmmeter? That is the proper tool to test for a short to ground. It will do a true insulation breakdown test. A regular meter doesn't give a very accurate reading. Fluke makes one of the best, but they cost around $670.

[@briangc1972]

megohm meters are for testing power leads and wiring. A standard Fluke meter ohm tester will properly check for short to ground compressors.

[@mskimmel59]

@@briangc1972 Not true Brian. The difference is the voltage output for the test. True, it will find a dead short to ground, but it will not identify a short at the rated voltage of the compressor. Many times I’ve seen 480 volt motors that show fine on a fluke, and a meg check dropped low at the rated voltage.

[@briangc1972]

@@mskimmel59 In over 20 years I have seen exactly 1 compressor with bad windings that ohm-ed OK with my Fluke but had a short that showed on start-up. That 1 time your megohm would have been helpful. Not worth it in my experiences. They are good for their intended purposes (testing power lines and wires), but not necessary for HVAC.

[@gor312]

@@briangc1972 You can also just clamp a multimeter around all 3 compressor leads and see if you get a reading. If you do, that's current flowing to ground. You can also make that test more sensitive by looping the wires through the measurement loop multiple times.

[@rodgraff1782]

@@briangc1972 Your dead wrong. You test a motor for grounds with operating voltage, not a nine volt battery. Yes, you can also use meggers to detect cable faults. I’d did that just yesterday. You test the windings with an ohmmeter. A high resistance short to ground, or insulation breakdown test requires a megger. I use AEMC crank style meggers. Megger tests are required during annual maintenance on most large equipment. Yes they are expensive, but it it the correct way to test the condition of the motor insulation. It must be done when the motor is at operating temperature, and the test is done with at least operating voltage. My megger will generate 250 volts, 500 volts, and 1000 volts. If you read the instruction book for the megger, it has all the instructions for testing for insulation leakage on various types of motors. 30 year Union HVAC instructor here, and 45 years in the field.

If the power blinks off while the unit is running I will blow a fuse .. replace disconnect with a non fused disconnect. This will solve the problem

[@georgekolos5255]

Probably should stop making videos , hire an expierenced guy and learn from him

[@ProPokerPlayer]

When I find a bad compressor and no obvious reason why it failed I look to the Cond fan motor. Bearings are dry and after running for awhile on a hot day the motor cuts out on overload. Compressor keeps running until it cuts out on overload. Awhile later fan cools off and comes back on and sometime after that the compressor does the same. Fan over heats again and this cycle continues until compressor eventually fails. Tech gets there and fan runs fine since its cool he never suspects the problem that occurs hours after he leaves. In the video you can see the brown area on the outside of the motor where heat has burned off the paint . When you see that combined with that elcheapo "Asian" made motor that WeatherKing used on them there is no way Im changing the compressor without replacing that fan motor at the same time. 2 other things I noticed that may or may not have nothing to do with it but....#1 That appeared to be "one time" fuses in the box and not "time delay" fuses. Never run an AC on 1 time fuses. #2 Those Mars capacitors are junk in my experience. Although I do occasionally use the Mars fan motors I NEVER put Mars capacitors on anything.

[@ibbriley399]

A normal, undamaged and functioning compressor has three terminals, each of which is connected to one another internally by the copper wire of the motor windings. The normal resistance value between each of the terminals will be but a few ohms. Reading to ground from either of the three terminals using the megohm scale has to produce the same value. The only variable would be the few ohms of the motor windings, which on the megohm scale would appear as zero. Therefore, if you are reading significantly different values from each of the terminals to ground, your readings cannot be correct. Further, your worst reading to ground, 7 megohms, would produce 17 microamps, which to a 30 amp fuse would look like zero and would not even trip a residential gfic device.

[@danielwilliams3978]

Check your speed (RPM) on your condenser Fan Motor. Could be running slightly slower at times.

[@virtual_bomber5698]

Probably due to, in your last video, you brazed the filter drier on the TXV with nothing to cool it down and you did not cool it down when you were done brazing the filter drier in. More than likely took life off of it and it has begun to fail. I also would have checked temperature drops across the driers to make sure they haven't clogged up either, to rule out as many possibilities of where the restriction is.

[@newmoon54]

Enjoy your videos! I'm a 45 year HVACR tech. myself. Recently retired but miss the heckle out of it!!! If you don't mind, I'd like to share some experiences I've had with very similar situations like this one here. Anytime I came across an older ~fused disconnect~ I would advise the customer to allow me to replace it, because I could change it out as part of that same service call charge,, and save them a future service charge. They almost always agreed to doing it right then! And those fuses are only 30 amp usually slo-blow, but starting load amps usually are around 80-ish amps, but can reach 100 sometimes! And if the customer couldn't afford the box replacement, I'd ask them if it was ok to replace the fuses with the ready-cut copper inserts/dummies,, and 99% of the time they agreed on it! Also, many times I would find the line voltage whip wire to be 10 gauge, which is rated for 30 amps, and I would recommend replacing the 10 gauge with 8 gauge stranded wire with a 60 amp rating! Doing this disconnect/copper insert, and wire replacement actually pays off for the customers! Also gives the service company additional revenue!!!! Keep the videos coming!!!!!!

[@jamesmartello1827]

Was the circuit breaker that was feeding the AC unit the wrong amperage so I fused disconnect was used to have the correct amperage on the AC unit. If the circuit breaker was correct why not gut the existing disconnect and install a non fused disconnect next to the old disconnect switch. Screw down the cover of the old disconnect switch to make it a junction box.

Checking ohm's ( resistance) across the windings C, R ,And S. Usually a good rule of thumb is the 3rd reading shoul equal the sum of the first 2. Then each to ground should be open or high megaohms. You can save time by doing it from the load side of the contactor on 3 phase or for single phase contactor and pull the leads from the cap to check.

Great video once again. I’ve had compressors that are down to earth that the multimeter couldn’t pick up but it was clear as day that it was down to earth once I used my megger. Definitely recommend getting one. Regardless, I hope changing the TXV sorts out the high head pressure 🤙🏼

[@jamespatrick9449]

I'm my experience a compressor that's operating properly pulls around half of its LRA when it starts and then same with its RLA, of course conditions change that some or heat mode seem to run a little higher amp. Most of the time when I see a compressor running like this one, it's not long before stop working. There is definitely some issues that need to be addressed with that system, but that new compressor in my opinion has suffered some damage since it was installed. It's running and pumping but it's life has been shortened. Just my opinion.

[@jamminwrenches860]

Scroll compressors always have a lower mega ohm reading, even so far as to show bad on many dedicated mega ohmmeter but they are perfectly fine. Something about the clearances of the windings is smaller, shorter gaps internally give low Megger readings to ground.

[@chrisscott1547]

I don't know why guys get so wound up about compressor Megohms to ground. In SOME cases it MIGHT be an early indicator of questionable insulation but: There is 120 volts on the compressor to ground. I=E/R so for 1 Megohm, current is 120/1000000 = .00012 amps, or 1/10th of a milliamp. No problem. Also, anytime I measure high resistance, nothing (no fingers) touch the item under test because your body will measure some Megohms across it - you don't want to shunt the device under test.

[@mikee2923]

Years ago I used to take care of cell phone towers that usually had 3-5 ton single phase Bard units. R-22 with Copeland scroll compressor. Brand new Copeland compressors would fail a meg test with either an ohmmeter that would read megaohms or actual meg tester. This was after recovering the charge, new drier evacuated to 500 microns and virgin R-22. I tested the compressor before applying power to it after weighing in charge. And it failed the meg test. Megger is a cheap Supco that considers anything under 20 megaohms as failing. My VOM that would read up to 50 megaohms would read about 5 megaohms to ground on them. However, the compressor would run and not trip the breaker or draw abnormally high amperage. Those compressors never failed. I don’t understand it. I had to replace a lot of these compressors and found this to be the case every time. Just recently I was replacing a small single phase Copeland scroll in a single phase York rooftop unit. This one was 410A. Same thing. I believe I read somewhere that Carrier doesn’t consider a hermetic compressor to have failed windings unless it reads lower than 1,000X line voltage ohms to ground. For example a 230 volt compressor must read below 230Kohms to ground to be considered to be grounded. I’ve also had times where my meter would pick up something to ground that the megger wouldn’t see and vise versa. Also moisture content in the system can cause lower resistance to ground. If I come across a compressor that trips a breaker or blows fuses, and I get a questionable reading to ground that seams random, I’ll replace the drier with a high moisture content drier and use virgin refrigerant and recharge the system. If practical I’ll change oil if the system is large enough and has provisions to do so. I’ve made it common practice to use high moisture content driers in any system that runs POE oil.

[@bodylanguageconsultant]

I had. Compressor that failed a few times. Went back and forth on the failure. Finally figured out when the home was built the electrician used 2 sections of wires and used a hidden junction box in the wall. Had to replace the electrical circuit from the breakers to the disconnect.

Or replace the fuse and fire up the AC and amp Out the line wires. If the amps keep climbing bingo you have your answer

[@rodgraff1782]

That fuse looked cooked. Check for a bad disconnect. Loose fuse holder etc. they make a plastic puller for fuses. If you tested for grounds with a megger, there would be no question. A 9 volt battery won’t find a high resistance short to ground. Need to test with operating voltage. From the looks of the nameplate, the electrical service to this unit is undersized. I’m sure you have a hell of a voltage drop on start up.

You Olm that fuse with power going to it. That could have killed your meter

I'm curious if I go back to the video where you change this compressor out if I can find the part where you drop those needle nose pliers 😂

wow here in florida we run 90 to 100 we always put txv and filter and a line flush with new comp that way we can make them last and a damm good vacuum down here in florida with 80 humid lol

Need to walk that circuit and check and tighten all connections and then change out that disco

[@TheFoxygrandpa69]

Man if you could do a video where your moving a little slower and explaining what your doin and why. I get most of it. But you move quick lol. Im not taking abt any video inparticularly but just in general.

[@bobboscarato1313]

He was too worried about having to replace compressor under warranty for free and pay out of his own pocket; big loss!

[@soloch69]

Great 👍🏻 video like always my friend keep them videos coming and stay safe out there

[@deanmartin1966]

I wonder if the heat in the windings on the compressor would cause a higher ohm reading? Your thoughts?

[@daniellundquest8252]

It definitely can. Anything that can conduct(copper, aluminum, etc.) has a resistance rating at different temperatures and different sizes. I’ve never had that become a problem but it’s good to keep in mind

[@georgekolos5255]

A megger" is a complete usless tool and a waste of time. Means absolutely nothing if such shows "out of range" / bad or if also shows good. Only way one can use if they kept readings of compressor on a regular basis with same operating characteristics ex. Outdoor temp, similar load on system etc since the compressor/ motor was brand new. Even if so. Still way too many variables to contend with. Nor sure what the point of a Megger is or why people use such to "test" compressors?

I have learned to ALWAYS pull fuses then I tap on them as I've found the blown ones to have a phantom voltage possibly due to carbon in fuse.

You should change that 30 amp solid core to #8 stranded wire.solid core can't carry the amps as stranded wire

[@benkuxhouse787]

You need to get yourself a megger insulation tester. That will tell you in five minutes if you’re windings are weak. Your problem here is your power wiring size, 30 amp line and if that’s a number 10 wire is very undersized says so right on the nameplate. That’s your problem brother. If that’s the number 10 wire need to run new wiring or they’re gonna have this problem all the time. Just show them the nameplate. Minimum ampacity is 36 A Max fuse size looks like it’s 50 if I can read it correctly. That’s what needs to be in there. You’re gonna always have problems with this thing tripping, that is why I always look at the nameplate on fuse wire sizes. I don’t know how hot it was inside the house but if it was really warm and humid you’re going to have high pressures. Something tells me that your temperature drop through that unit was just fine. If it was sweltering high load you’re gonna have high pressures and hi super heat until the house cools down to its comfort levels under 80°. You may even have to come back the next day after doing a compressor change if you are concerned about superheat it will take hours to pull down

Always check the pressure drop across that suction line filter after a compressor changeout. Suction line filters will always cause eff. to be reduced and should be removed after it cleans up the system from a burnout.

[@farshadfaridmehr7271]

You told compressor just replaced, after soldering there could be dirt layer inside the tube and after starting it'll goes to he txv filter or orifice and clogging the path. Check this it may help. And please tell us what was it after repairing.

[@crapmusstank6558]

I've had my fieldpiece give me wonky meg readings that would pass on an actual megger. I still love fieldpiece but don't trust any meg readings from it anymore.

[@keldon_champion]

man... I hate mega ohms to ground it's such a grey area I and I hate condemning a compressor (or any big part) on a maybe, its a diffrent story when its a small part but a compressor that sucks. I just had an undercounter chefs draw that burned out the controller and power switch but I found 9 mega ohms to ground off the wires to the controller traced it bad to the condensor fan so they are getting all 3 parts. I'm glad you found the issue and it wasn't the compressor good job following through to the end I have seen so many people see mega ohms to ground and just say well thats that and order another compressor.
