You can't blame it on static pressure, you can't blame it on humidity getting into the motor..... I love it brother! Those are my sentiments exactly.

My HVAC guy came Fri. because my heat pump wasn't working. Bad news, system totally dry of coolant R-22, and compressor had dumped some oil. It's a 3.5 ton unit 13 yrs. old. He recommended new system. I'm not too thrilled but I guess it has to be done. We've got emergency heat (split system) and gas log fireplace (LP) I want to make sure I have a good system before summer heat sets in.

Just came across one of these yesterday. So glad you had made this video. Great advice thanks for the help man

I really like the way your present your diagnoses and fixing HVAC systems. You are so informative. Also just wanted to say take care of your health for yourself and family along with your clients too.

Great troubleshooting and change out on this fan motor 👌

Got yourself a workout there, Good job Curtis, I can tell your ribs getting better, you went at that motor at full steam.

Looked this up. Have a service call to go to tomorrow on 4 ton Ruud package heat pump most likely same issue from the description of the problem from my customer. Good video. Unit is only 1-1/2 years young. Crazy!

Good little fan motor changeout vid ... Thx ...

Great video, sometimes doing it all by yourself will make you tired and frustrated, but you got it under control. ✌

You are correct static pressure my foot in carrier folks in ga exscuse I've had 2 blower motor on one dual fuel gaspack go bad in 7 yrs glad I registered it for the 10 yr warranty

Tidy work 👍🏻

Saturday calls bring out max speed in a technician during nice weather. I found a bad heat exchanger today and your short sleeving on a.c.unit. Enjoy nice weather. Hope ribs are doing better.

Inside the round controller there is an $8 thermistor that limits inrush current. That is the likely failure mode.

Thanks for the videos 🥃🥃🍺🍺🍺⛳🎳 Stay safe. Retired (werk'n)keyboard super tech. Wear your safety glasses!

Few months ago I yanked out an indoor motor on an air handler!!! Same type … ECM!?!?! I installed a regular PSC motor! And put a relay in to work with the fan control board! I asked (the supply house) the difference in ECM vs PSC…. He said lower locked rotor amperage! So I asked what’s the difference if you run a PSC motor on continuous fan (run load amps are about the same!!!)🤔🤷🏽 So I’d really like to see the difference in a power bill when both are ran nonstop! I personally jus think it’s another high dollar addiction to what could be a more standard reliable operating system! With a satisfied customer & a service tech going where he’s really needed! “Keep it simple!” QUIT THINNING EVAPORATOR COILS FOR MORE EFFICIENCY TOO!!! More refrig leaks on da way in da process 🙅🏼🙅🏻‍♂️🙅🏽‍♀️

I see what you're saying about the ECM but you can't run an indoor fan constantly. During cooling season you'll reintroduce the moisture on the indoor coil back into the living space and there will be an issue. It'll also feel like they're living in a cave, cold and wet. The blower must turn off after a call for cooling unless there's auxiliary dehumidification.

Those motors suck but they help me pay the bills. Thanks

Right now we're seeing a wave ecm fan motors fail on 16 seers rheems all within 5yrs old. It's pretty upsetting, we've already had 8 warranties in the last 3 months. They're claiming is water related, but it's not just rheem, it's across the board. Also had our first compressor fail on a unit less than a yr old, (the new model).

There is a part in the module that causes that problem it is the choke

What is the blue wire, what does it do, and where does it connect to. Thank you

Can you have a 50/5 Capacitor and install a condenser fan that says CAP10? Will it still work properly?

Would you do a video on Rheem heat pump 2 ton condenser fan doesn't turn off and how to fix it.

If you are having trouble separating the fan blades from the motor could u tap on the shaft of the old motor with a mallet to dislodge it?

@amiatroll6347

No, that risks mushrooming the shaft and you won't be able to remove the blade without a lot more effort.

Please share how many years youve been doing this and where you got your training and education.

Good video tho

Recently bought my house. I noticed that my Rheem AC unit's outside fan will spin for 15 seconds and then shut off for 2 mins. It'll turn on again for 15 seconds and then shut off. Rinse and repeat over and over. Called a buddy of mine. He does some HVAC work. He says my unit has an ECM. He doesn't know to much about them. It appears to be similar to what's going on in this video. His buddy says that it's normal. I don't feel like it is. When it was 90 degrees here, my house was blowing hot air until night fell. Then the house started to cool down. So long story short, should the fan always be spinning when the AC is turned on? Thank you!

Always take the panel off, always do amps, always do pressure, subcooling, always calculate uF while running

Whats the name of the last part installed ? Is that the module?

On the condenser ECM motors, I assume they still do the 15 second run in each direction to determine proper rotation? Once they do the initial rotation procedure, is there any way to make them redo the initialize procedure?

@Garth2011

Жыл бұрын

Depending on the make of the motor. An OEM motor is programmed. The Evergreen motors self learn rotation at first startup but I'm unsure about the speed programming.

Same issue.. my module..I think...😁

I've never seen an outdoor fan motor save any energy by being ECM. I mean, they always pull .8 amp current for me. Unless I'm interpreting that wrong....

I work on rheem/ruud and it's not as uncommon to have their ecm condenser fan motors that will thermally trip over and over. It's a clear symptom they are bad.

I wish folks would get str8 to the point lol

So is the ECM condenser fan motor just on the heat pumps ?

@davidperry4013

Жыл бұрын

They are often found in AC units and heatpumps with variable speed compressors in them but they are of higher grade materials since AC units with variable speed compressors are made to last longer than single stage units.

Not your design, but what a wonderful place to tie any and all excess wires???

Should fan motor be replaced when vibrating excessfully.

Is the typical for a Rheem unit to have the fan motor fail after 3 years?

Have you ever run into a situation where an ECM fan motor would not run if the line voltage was slightly high? By that I mean 242 to 243 VAC. Do you have a video on swapping an ECM fan motor to a PSC motor?

Psc motor is simple. Wire it up to a capacitor and l1 and l2 on contactor. When contactor pulls in it will cut on. Just don't do that on a heat pump cause then it won't turn off in defrost
