I'm about your age and at first I watched one of your videos and thought your were lacking knowledge because you weren't sure and I found no follow up . But I've seen more and read your comments and turns out they're the fools. You do just find sir . My apologies you are skilled and do interact well with customers while working with ethical integrity.
I've watched most of your videos. And I did AC over 30 years. This video was something I needed to watch. I'm changing his ECM this week. Thanks for your videos they do help.
I’ve done hvac for a few years now and I have yet to see this exact Rheem unit. I’ve seen you work on it a few times though, wonder why lol. I’m not too far away in NC. Thx for video!
Great Video!! I need some advice. I have the same model Rheem heat pump a few years older, the blower motor is running non stop, the compressor works fine heats my home. I can turn the thermostat completely off blower still runs. Thanks for any help.
One Question? I just ran into this Two days ago! Can the low voltage switch on the board handle the higher 120 volts or should you use that to power and use a fan relay for the 120 volts to the fan? Thanks for all your videos! I literally run service calls in SC for my friends AC company and repair and maintain my rental units from what I learned from you guys on TH-cam! He called me today with the same issue and I explained everything to him! You can't make this Ish up! Thanks again!
I found a video from a non-HVAC guy who depotted an ECM module and points out some of the electronics. Just good for FYI as there's not much that could be done in the field. The video is Genteq ECM 3.0 module Teardown and Analysis, on Tom Kirkgaard channel.
Nowadays they're potted very solidly and can't be done. In the old days they weren't potted and could replace a failed surge protector, varistor, or swollen cap. But I supppose potting the circuit board in a motor intended to be used outdoors with all the rain, snow, hail, ants, critters etc isn't a bad idea at all. Also maybe slows down China from reverse engineering it by maybe 5 minutes. LOL.
When a heat pump runs in the winter the outdoor coil can ice up. So, defrost runs it in cool mode which runs the hot gas outside. It’s more effective when it turns off the fan. That’s what the board does, that and turn on the heat strips to keep from blowing cold air inside.
Nice to see a "rescue" motor that has real ball bearings vs. bushings/sleeve bearings. My guess on the original motor is the ECM part is bad, not the motor itself, which is common on those X13 OEM Genteq motors. I still don't understand how a company can still be providing defective motors when its so well known that they will fail and usually for the exact same reason, the "NTC" on the ECM module. A $2 part burns out because it is not able to support the intended demands or the part is simply a junk design on a $700 motor.
You put the wrong capacitor on there it should be a 7.5 on 230 volts and your amp drawer should be 1.2 are below. The 10 MFD capacitor is for 208 volts
So did you go back and install a 7.5 MFD run cap? The box has two capacitors listed and the 10 MFD was for 208 vac. Clearly this is not a 208 vac system because you measured 240 vac at the contactor. Look at the front of the motor box again and you’ll see what I mean.
I’ve learned that you can’t buy just the module - gotta get motor and module together. So, once I see it’s not working when it should be I don’t go any further.
Its usually the module that fails however, replacement of just the module is only slightly less than a complete new ECM motor. The savings isn't enough to risk what life might be left in the existing motor. $700 I believe is what they sell for and the modules are hard to get in addition to very expensive. A new module is going to fail in about the same time, 5 years. This is why HVAC folks offer the PSC version and the PSC motor is a little less than half in price.
@@n.gineer8102 you should see what the Japanese get up too, eg Fujitsu, Mitsubishi, Panasonic, Dakin etc. They have plenty of 25 seer units and even some 30 seer ones now. They have an obsession for efficiency with stuff like electronic expansion valves and 3ph inverter compressors.
Don’t understand why you didn’t even look at the capacitor that was already there, why use 2 when you can use one, 2 items that can fail now and a capacitor charge for each one, there goes the saving on PSC motor…..
Of course the motor craps out one month after the warranty period. And no consideration of covering the warranty from the Company. Why do you just yank the wires from the terminals? To protect the terminal from being pulled from a board, a relay or contactor, or another wire, more care should be used to remove connected wires.
I can't really see where a ECM on the condenser fan motor saves a whole lot of energy. If somebody has an actual engineering study, please share. ECM motors are more likely to fail than traditional PSC, cost more, harder to work on. Government mandates though so here we go to comply.
Dear Mr. CUSTOMER, I'm going to install a motor that will cost 20% more electricity and has less control over the airflow. You ok with that. Mr. Customer says sure go right ahead 😆
@@97Napkins And in the long run he’s doing the best thing for his customer and saving him money. I’ve done it 100 times and not once have I had a customer call me and say they believe their electric bill has gone up
I would never do that. The rescue motor that is psc costs $150. You can get an evergreen ecm motor for $180. With the psc you need a cap, so you’re saving $20 in parts. I do flat rate repairs. I would charge $350 for psc and $375 for ecm. Im sure the customer will spend the extra $25 that they will recover in one season of cooling. I love the video but that unit is too new to retrofit something that was not designed to use. Sorry but this is a diservice. Before someone tells me the ecm motor cost more, it’s available at Johnstone part S82-490
@@97Napkins But that motor failed after 6 years. ECMs are good technology but far to delicate and sensitive to airflow for how people commonly treat their AC/heat pump.
Customer had their choice. At least they won't have any motor issues for a very long time. Depending on their energy rates, they may not notice much change in cost to run a PSC. If they have high rates like those folks in California, 40 to 50 cents per kWh, I'd agree the PSC will be noticeable on an electric bill.
@@Garth2011 -- not only is a PSC motor considerably less efficient, but that efficiency loss ends up as added heat load on the A/C. But yes, all you can do is present the facts to the guy paying the bill and let them make a choice.

Glad to see you back in your truck....Thank you for explaining what your doing as you go....We all learned something today !

That umbrella idea is kick ass!

I love my PSC blower motor one of my HVAC tech buddies replaced the ECM motor with.
Good video brother 👍
I never Tye any wires to the refrigerant lines. They always rub through and burn a hole in the lines.

Great job, I hate those ECM...for the 2% of energy they save it's not worth the price on the replacement motor....
20%
Paul, They are the worst. My air handler ecm motor isn't running. Same Rheem unit he worked on here.
Depends, variable speed blowers tend to be a lot more quiet as well and they disperse air a lot more evenly as they maintain a constant CFM
@@timrob0420 Yes and they speed up as the condenser gets clogged, trying to maintain a constant torque on the fan blade.

Ah so the board turns the fan off when in heat pump mode. The board has nothing to do with ecm motor

Wasn’t nice to see the rescue motor on my unit had bad bearings and the techs did nothing about it
Boo
Everyone of those motors I've ever replaced the blade never wants to come off.
I know, right!
What kind of camera are u useing
And to buy one
@9:38 they're called "grommets" they protect the wires from sharp penetration hole edges.
Those things are called strain reliefs. Heyco makes a cool tool just for them.
BTW...Nidec or U.S. Motors seems to be a really great aftermarket brand of motors to choose from. They are a Japanese company !
Awesome vid
You put the wrong capacitor on there it should be a 7.5 on 230 volts and your amp drawer should be 1.2 are below. The 10 MFD capacitor is for 208 volts
I caught it in time. But, you’re right it’s supposed to be a 7.5
Nice one 👍🏽
The wire protectors are called groumets,i would hate having a house that close to highway

What size are the nuts that mount the motor?

Yes more dependable motor . Blower not to bad to do either
Was it only the module that was bad or was the motor itself shot

Someone didn't register that unit. 5 years.....
Exactly
that would be a grommet to protect the wires
That was a lot to only save the customer 100 bucks when the price is that close I wouldn’t even offer the psc.
Is that a two fan motors or is it something else
This is my first time seeing two motors in one unit ?
Just one motor - two pieces
The defrost board makes things more complicated.
It seems you work a lot on those a/c combo packages. Are those in residential homes or businesses or both?
Both
Was the defrost board dry contacts breaking the 24 signal with the ECM? And now your using it to break one side of the high voltage for the PSC?
dry contactor coil on the board uses 24 v, and dry contacts you can use 24v or 120 v load power.
My Bosch heat pump has an ECM fan motor. Hopefully it lasts😃
Paul, It won't....
@@classic287 so far so good
The whole unit will not last
That thing is called a grommet
You call them a plastic bushing…👍
Grommet too.
Vans make life easier. I really don’t understand why a ecm on a condenser. Engineers should be forced to work on their own equipment as punishment.
Because it's much more efficient than running the motor at full speed when it isn't needed
You mean politicians. Engineers are only doing what it takes to make it meet efficiency as required by law.
