Hey look a statement i dislike. But not because of Sporlan. Tradition is something you should never state, as i have time and time again seen companies with a tradition of cheating the customer, delivering bad work and lying..

That evolves from a drive to do the job right. Unfortunately you do have to watch many others do the job wrong to spool that up.

At the end of the day, the goal is for getting people running and everyone going home safe.

[@ShukenFlash]

Great explanation of what a circuit breaker does. So many people have this idea that the breaker is to protect you/them. A standard breaker couldn't care less if the power is going through something plugged/wired in or you so long as the current isn't above its rating. It will let you get electrocuted all day long. It's there to protect against overcurrent that could cause a fire or other hazard. GFCIs are meant to protect you, and some breakers do have those built-in, but a standard breaker ONLY protects the wiring and ONLY looks for overcurrent.

[@TrystyKat]

It doesn't even protect appliance cords. If the fault is in the appliance or its cord, and the cord isn't sized to handle the full fault current required to trip the breaker, too bad.

[@dashcamandy2242]

Last week, we had two separate electricity fluctuations at the donut shop due to high winds and tree branches. Both times the power flickered, I needed to reset 6-10 breakers to restore power to 110v and 208v equipment. One circuit had barely 2 Amps of load (wireless headset system) on a 15-Amp breaker, another circuit had about 4 Amps of load on a 15-Amp breaker, etc. Over a million bucks spent on "renovations," and the worn-out 1990s breakers are still in the panel. (EDIT: Most of the breakers don't "click" on or off, they have very "mushy" operation that is more than a bit concerning.) If our 208v espresso machine starts working, you can hear the 480v microwave convection ovens' internal fans slow down. If the microwave convection ovens are cooking something, all the LED lighting overhead starts flickering. At this point, I'm simply waiting for the place to burn to the ground so I can stand there with a smug grin and say, "Maybe next time you'll listen to me?"

Good job diagnosing it. That’s absolutely insane that 2004 was 20 years ago.

[@zenronaut]

Hey Chris, I love watching your videos even if I'm just a sparky, it helps to show me troubleshooting tidbits, I did notice though that at the beginning of the diagnosis you checked for continuity to ground, however its also good to check for continuity between the phases before re-energizing a tripped main breaker as I have seen a scenario where 2 phases were shorted together but weren't shorted to ground.

[@richardbartlett6932]

That is a possibility for sure. Sometimes you can confuse yourself as you can have a low ohm reading between phases but not a shortage. But yes best to check while you're at it 🎉

[@FerralVideo]

Excellent troubleshooting skill on display here. That thing had to have made one heck of a bang when it went. My first thought was that contactor looks like it may have closed on a phase-to-phase short. How that short got there? The world may never know. At least until you get a chance to angle-grinder that compressor apart. I'm so looking forward to this one. I think it either single phased from a failing contactor and/or prolonged overheat degraded the oil and windings until something went phase to phase short, just in time for the unit to call. KAPOW.

[@NATHANFREDERICK-rs7yb]

Your the greatest. Nice job. It's very important for people to realize that those are not always a current. protectors. Also if the lower circuit of the evaporator is the one that's not working it can cause water leaks in more humid climates, although that should not be a problem in Southern California. (But don't quote me) Contactors should be checked during a p.m.

[@NATHANFREDERICK-rs7yb]

Yes, you're 100% correct.

[@gregmercil3968]

I replaced some blower pulleys on a couple of similar Lennox units last week. I couldn’t believe how stupid easy it was, it was especially cool how just with the removal of two screws that whole blower assembly can slide right out. As for those core depressors, I just recently discovered those marvelous little things. I picked up a cheapo Yellow Jacket version out of necessity, so I could pull a vacuum on a system with those stupid coremax valves. I plan to eventually get a couple of those Appion versions. I have an Appion vacuum rated shrader core removal tool, and finally used it for the first time yesterday. They definitely make a quality product.

Looking at the temperature of the first register does show total system performance for a unit which is important from the perspective of mechanical engineering. However, looking before you pickup motor heat in a draw-through fan type of unit should tell more precisely about your refrigerant system's performance. At the register you have to remove the motor heat and that's more of an estimate unless you are getting pre and post motor readings.

I would totally guess here that the motor shorted internally between two phases, (1/2) and then fused/melted the contacts together on the contactor. It then melted the windings and opened up internally. I am surprised there are no fuses internally in the unit to protect all the internal wiring of each fan / compressor. I see the one set of fuses, but assume that is for the fans. 👍🤠

[@JoseLgamer05]

European here, so my point of view about electrical stuff if going to be different from the one an American would have. I noticed that the contactors have no overload relay or any other means to shut down a compressor or blower motor if they run into an over current condition. That seems dumb, if a motor would run into a situation that leads to it pulling more current that what it's rated for, you want it to turn off to not burn it out. What I want to say is that the way that unit is wired seems, to me anyway, to be asking for this sort of thing to happen really.

[@nightshadelenar]

i was noticing that as well. yeah, it is a few extra parts but O/C protection on anything high RLA (>8A) is safer than just hearing a compressor go bang or a blower motor become an expensive grind lighter. Still possibly wouldn't help if a winding was going short to another leg, though. especially right on startup where things get risky as it stands.

[@bobhorner2845]

NOT SURE WHY BUT, THE 2 BURNT TERMINALS SHOW A 1 PHASE CONDITION DOWN TO THE COMPRESSOR. YOU CAN PROVE IT WHEN YOU OPEN THE COMPRESSOR AND THERE IS 2 BURT, 1 GOOD PATTERN ALL THE WAY AROUND THE WINDINGS. I WORKED IN AN ELECTRIC MOTOR SHOP FOR 24 YEARS.

[@jakubiszyn96]

My guess is the stage 1 fans are powered by one relay just for stage one, and that relay wasn't activating due to the pressure switch, so either he switched the wires to a different relay from a different stage, or switched the wires from the output side of the relay to the input side to get the fans running for the test.

Hey, i really love your videos. You have an overall great attitude regarding the way you are doing your job.

[@catfood9707]

Two things, when you tested the resistance of the dead compressor and found it open. Could you do a resistance check to show a good compressor? I mean the second stage looks like a similar concept.

The oil on the motor windings may act to breakdown the coating on the windings and the dirt that gets stuck in the oil can act as a thermal insulator. Kinda like "fixing" a fan by spraying WD-40 on it. Once it gets on the windings it's only a matter of time. After figuring out how the motor got coated in oil and eliminating that problem then the motor should be replaced or put on a watch list because it's gonna die sooner.

with the burned contactor I would have removed the load-side wiring instead the coil is designed to handle long-runs and the part we are isolating is the blown compressor electrically there is no difference to a welded contactor to just remove load or supply side, they both effectively remove the welded copper bars from the circuit now from a safety standpoint it is slightly less safe to have 150a 208v three phase exposed and not connected to anything, but as this is the control box with other similarly exposed 208v three phase connections I see no benefit in removing the supply side instead of the load side in fact it is silly to remove supply with the included contactor power transformer wiring, just isolate the compressor from the AC supply actually just unplugging and covering the molex with a temporary flag and tape would do just as well, you flag it as "blown contactor and compressor, do not re-plug" and problem solved

[@petermichaelgreen]

My understanding is that most breakers in the USA have distinct positions for "off" and "tripped" and you have to move the handle from the tripped position to the off position before you can reset it. This distinguishes a tripped breaker from one that is just turned off and also makes resetting more of a deliberate action. The din-rail mount breakers we use here in the UK on the other hand normally have no such distinction.

[@weld3z]

@@petermichaelgreen Makes sense, Thanks. In Dubai also on/off never saw something with trip

I don't like how you are using the schrader core compressors. If you are not bleeding between the probe and the core compressor, then it means that the air, all the way from the sensor to the valve part inside the schrader core compressor will migrate into the system. The air will not stay in the bottom of the probe, it will mix with the refrigerant into the system. Not the end of the world, just the feedback you are asking for sometimes. After 10 times probing up, it may be an issue if it is POE oil.
