GAS FURNACE MOTOR DRAWING HIGH AMPS TROUBLE SHOOTING TO FIND ISSUE

[@tedparkman3111]

For a plumber, your a danm good electrian Steve. Awesome job!

[@bradleythomas5445]

That was a tough one. Great detective work, Steve.

[@PSB-900]

You're brilliant Steve! Great troubleshooting work.

[@J-Colt]

Nice trouble shooting Steven! Thanks for posting!

[@josephcade3541]

Steve you should ohm out the windings and ground on the motor. That would tell you straight away if the motor is bad. And if it's bad when you get a new motor you should ohm out the windings to be sure that the new motor is okay. And be sure to put the amp meter on it make sure the proper amperage

[@chuckquinn8026]

Excellent diagnosis Steve!

[@JavierGalvan-s2f]

That looked complicated Steve, great job determining what wire to which, that's why I learn SO much from your video's! Enjoy the long weekend and don't forget the video's! 🎉😎💥💯☝️👍🫵

[@josephcade3541]

Steve make sure you check the capacitor for good health. If a run capacitor fails, the motor can display a variety of problems including not starting, overheating, and vibrating

[@FemboyEngineer]

Lack of phase shift

[@Todestelzer]

He checked it. It’s in the vid.

[@Daleeather1975]

Hello Steve Great job troubleshooting 🤩👍

[@MetalDetectingwithCZkidd]

Well done Steve. Every now and then, you'll get that long one.

[@WeatherNut27]

Troubleshooting from hell. I watched every minute. Nice job explaining your thoughts and reasons for things.

[@josephz9006]

Wow this is a perfect example of why i do all my own Plumbing electrical and and anything in-between

[@MikeMcCue849]

GREAT VIDEO STEVE, VERY INFORMATIVE

[@trackman515]

In the old days I use to ohm the windings.

[@PianoRevisited]

When Steve says "that's queer " - we got problems, Mama ! Between old Nervous Nellie and this Daycare - that's a full time job. 😅

[@craigs3183]

Cluster F pain in the A . Good call getting the electrician to check out the main wiring.

[@zackmax7184]

36 Amps is a lot unless that is a Heavy Duty Light Switch. I think a normal light Switch is for about 15 or 20 amps.

[@DEW409]

Looks like you are energizing two speeds at once, which will burn out the motor. The fan really is spdt, and should send power to either the bonnet fan control or directly the blower high terminal for ac. That way you can turn on fan from the thermostat when heat is on without destroying the motor. Of course what you did will work, since you are just using one speed.

[@stevenlavimoniere]

problem is there is 2 seperate tsats for this unit .. that is going to be adressed next . it should have one . been wired like this for 30 years

[@JamesAgans]

Wow, great tip, thank you!

[@JamesAgans]

​​@@stevenlavimoniereHi Steve, I missed your banter with Miss Moly on this one. I recently lost my little girl Aussie- Doodle MaKenzie. I live alone like you and I miss her badly. Its amazing how much they mean to you, and how much you miss them when they are gone. 😢Thanks for all the education you provide.

[@1022hard]

Great job Always Steve!

[@TomLawson05]

Steve that was a real head scratcher good job thanks for the video

[@dannyg1809]

25 minutes in and I’m pulling my hair out 😂 I’d give it a good kick and hope for the best! Your amazing Steve!

[@JamesAgans]

The blower DRIVE BELT on the FHA furnace my dad had installed in 1948 lasted 35 years until 1983. The motor nor anything else on that furnace ever did fail, but the furnace was replaced to provide central air conditioning in the 90's. The heat exchanger on that original furnace was cast iron. When I hear HVAC people calling 10 year old systems as needing replacement, it shows me how people in this country have been willing to accept cheap, not fit for purpose Chinese crap for way too long.

[@frankchandler8005]

I SEE MISS MOLLY AT THE HELM IN THE TRUCK. STEVE DO YOU BUY YOUR PARTS IN BULK ON LINE OR DO YOU GO TO THE SUPPLY HOUSE.

[@kevindean2016]

The black is common the red is normally open and brown is normally closed so when the relay is energized you will get power to the red wire

[@eddymumford4086]

getter done 👍👍

[@deanguando1335]

The wiring is really jammed into that small box.

[@MrMultitool]

Great job

[@electrickal1]

That had the potential to cause a house fire!! An RCD or (GFI in north America) would have prevented a lot of those issues including allowing you to jumper the neutral to ground. I'm an electrical tech in a UK hospital and bypassing safety switches is a serious no no, they are there for good reason and should never be removed, bypassed or cheated. Death, fire or injury caused by those actions can be traced back and litigation taken against the person who modified the machine from it's design criteria, absolving the manufacturer of all blame. Be careful what you are doing.

[@DwayneBaker-r2z]

Steve,there is a squirrel in the cage MAMA

[@tim5158]

One to many hands working on that equipment , hopefully you got it.

[@fanofoldfans9238]

Steve, That was a great troubleshooting skills. 35 amps! Almost as if the motor was getting 240VAC instead of 120? That time/ temp limit switch is fried allowing power to the low speed and high speed windings... Great job

[@electrickal1]

Ohms law stipulates that voltage and current are inversely proportional to each other, so doubling the voltage would halve the current.

[@fanofoldfans9238]

Doubling the voltage would double the current! And because it's an inductive load it would more than double. @@electrickal1

[@electrickal1]

Apologies, you are correct. V=I times R and the power would quadruple because it's P=I squared R.@@fanofoldfans9238

[@JamesAgans]

I really feel for you service guys with all the Chinesium parts coming onto the country.

[@vic5979]

Now that’s what I call rocket science!!

[@KW86.]

Awesome video. How many of us repair guys has balls to call electrician, we want to tare house down some of us

[@TheAnalystradioprogram]

Steve why don’t you have some kind of rig where it’s a plug with the other end spliced and you just hook up to the motor with the 120 direct to see if it spins? Then you don’t have to remove it to test.

[@kentbassler5037]

Steve I didn't see you connect the motor shaft to the blower wheel ?

[@stevenlavimoniere]

i did just trying to keep the video as short as possable

[@stevebrickley3295]

“I should have one of them in the truck.”

[@picklerix6162]

Steve has a parts store on wheels. I never carried as many capacitors as he does and he carries some of the most obscure toilet parts that I have never heard of before.

[@dexenationgracey1979]

​@picklerix6162 You could make up a part that doesn't exist, and Steve somehow has it in the truck.

[@sherwinalvarez7365]

​@dexenationgracey1979 😂Thats a fact.

[@papaleos9360]

Imagine the hundreds of hours of drive time he has avoided over the years by having so many parts on the truck.

[@rodneyskinner7741]

Hello Steve!

[@Mark.R_]

Signwriting on the new truck.

[@BobSmith-mj7ik]

Good diagnostic skills. Anyone else would have just thrown a motor in it and walked away.

[@richardsciranko3004]

Well didn't he do that with the first motor?

[@SeersantLoom]

Good idea to check current draw after motor replacement. I've seen at least couple of HVAC channel guys doing it regularly, just for assessing system health. They double check all the voltages and amps on all phases, compressors, fans, measure voltage differences on relays etc.

[@adamdavies163]

Job satisfaction eh Steve? Always great to fix an awkward one.

[@kevindean2016]

Check the voltage with it running..................that will tell the story'

[@Joseph-jx8bl]

I think a couple of my wires fried watching this post…….so it was basically getting double the juice and it cooked the motor etc?

[@iamnoone.]

Howdy Steve and Molly

[@robertwojtowicz933]

Good video, Steve 👍

[@kaib1125]

this thing just missed you it wanted your attention again :D

[@ntsecrets]

Wow I wonder if all the issues in the past were due to that cycle switch?

[@jblyon2]

It's possible. I seem to remember at least another video where someone had a furnace that was repeatedly acting up and a very similar looking cycle switch was the issue.

[@memyselfandifarmer]

Two power points going to the motor.

[@Altmechanic]

The electrical always get most of the guys. Steve knows his shit, not easy mama.

[@tonym6920]

[@bruce8572]

I've seen that happen when it tries to run with 2 of the speeds are wired together..

[@porky7753]

Steven, it's Labor Day weekend. Pick up a T-bone steak for Luna. lol

[@alnonymous9361]

Energizing multiple speed taps will burn out a motor quick fast in a hurry. The fan cycle switch with limit is only supposed to energize the motor through the normally closed contact on the relay which will disconnect when cooling is calling, therefore it would be impossible to energize multiple speed taps at the same time unless it was miswired. NO! Don’t use ground as a neutral! Don’t trust fieldpiece. Do not bypass safeties, do not bypass door switch, that’s shake hands with danger. Usually you don’t want heating fan speed & cooling fan speed to be the same speed. Too low fan speed in cooling may freeze the evaporator, too high may not dehumidify enough causing mold & mildew. Too low fan speed in heating will overheat, too high in heating will cause condensation in the primary heat exchanger & quickly rust the heat exchanger making carbon monoxide potentially harming occupants.

[@JamesAgans]

Very GOOD information, thank you! 😊

[@josephcade3541]

That capacitor keeps the motor healthy otherwise it overheats and so does the wires

[@billderby1527]

Hard to tell because of your tape and camera didn't show clearly but I suspect you have wired up black from the motor to the 120v hot. This black wire from the motor is high speed. You then wired up the red wire from the motor to 120v from relay. This red wire is a lower speed. Attempting to run both high and low speed at same time is not good. The motor is off on internal overload. if you ever feel a motor and it's hot, cool it off before condemning . What we do know for sure is it is not the power switch as you have 120v to furnace. You always have to have panel on when checking amp draws otherwise the lack of static causes motor to draw over amps. Try just wiring up only white and black wire from motor of course the cap needs to be wired to. Then put on door and check amps.

[@priyajakatdar3759]

Why replace the relay, bypass the door switch & try to fix a working connector without checking basic wiring? Perhaps I didn't get the point of the video.

[@gordonpotts753]

Molly in the background. Lol.

Hello all.

[@zunar_j5_933]

[@bashirmohamed7982]

[@donhorn548]

Good trouble shooting.

[@zackmax7184]

Might have had a Fluffy Chewing on the wires.

[@deanerbes5725]

That's the problem with using 2 speeds and those old limits.

[@jeffreywhitlatch1409]

A day in the life and the f'd up stuff you run into out there. It sucks frying a motor because of a bad fan control that probably fried the motor before it. Straight cool t-stat with heat and omit fan control. If enough wires and a 24volt gas valve, heat anticipator in it. Good YOB.

[@williegillie5712]

Should of ran lol. Good sense of humor. But hey I knew you’d find the faulty furnace fan.
