Customer called about blower not running, found an X-13 barely turning. Replaced with a PSC motor. #hvac #hvaclife #fieldpiece #ICP #makita #X-13 #usmotors
Kind of a crap shoot...lower the original efficiency and design by going with a more reliable PSC idea or use the more expensive OEM motor/module. The savings in power may never be reached due to this ECM failure. I'd personally opt for a new ECM vs. the PSC in the long run.
My Goodman Variable speed motor module went out after 7 years... Prices for a new motor with module were 800-1200, Ouch. I found on Ebay a company in Florida that had 2 modules, programmed for 200 for the pair. I bought them installed one and this is good for now. They were telling me after this I will have to convert like you did on this video. Thanks for walking us through this change over on this video!!!
@@Garth2011 The DoE MANDATES the use of ECM motors on newer systems(ive been told 2016 forward). Theyre junk and fail..probably because they have no capacitor.
@@fredost1504There is a part inside the ECM module called a thermistor which is a thin black round looking disc about the size of a quarter. That part is what fails and it is about a $2 part which can be replaced but likely not something all HVAC folks can or would do in the field. If they installed a quality thermistor, they would not have the problems they do and the sad part is, a completely perfect motor is being wasted when they are replaced with a new one. The ECM can be replaced however, the cost of those are almost as much as a complete motor assy plus, availability is a problem, "out of stock" most of the time. There's a replacement made by Evergreen which will self program rotation as a "good" replacement.
Man you really know your stuff !!! I need to come ride with you for a month you have the ability to change peoples life’s with what you have learned thanks for sharing brother!!
Thank the tech gods everyday for RU-vid! All this training and cool shit at our fingertips! No way we’d ever be able to take enough “ class room hours” to get all this before we were 80 years old haha! 👊
@@Samlol23_drrich Ive replaced many expensive electrolytic capacitors. They quit working all the time. And the three phase motors (behind the expensive electronics) are much more reliable than single phase motors. And Electronic controlled motors can do things that a single phase can never do.
@@Samlol23_drrich Your experience will depend on which type you purchased. A 3 phase motor with the electronic control system at the surface would leave your downhole equipment very reliable. Just be attentive to grounding, especially if you have PVC casing.
Did the same thing in my house. No need to worry about the time delay here in Florida, no heat exchanger, inside the furnace, to worry about getting too hot.
All good except for cutting the OEM connections to fit the PSC set up. I'd have left about 4 or 5 inches extra on them just incase the owner wanted to go back to ECM at a later date. I'm sure they save a few hundred with the PSC. Great repair plus that ECM motor could go to a discount or senior citizen job for the cost of the module only.
Nice job. If it is out of warranty I always recommend a PSC replacement as well. Any savings from the ECM is gone with one out of warranty replacement and the reliability is much higher. Oh, and thanks to seeing it in one of your videos I got myself one of those Makita fans. Loved it this summer!
Yep...those ECM designs/engineering should be required to carry a 10 year or longer warranty on them. For the money they charge, about $1,200 I think, and the push from the Government to use them, someone else should be pushing that kind of engineering/quality to either be better made or carry long warranties. Quiet Cool has ECM motors on their whole house and attic fans and they warranty them for 15 years !
Curtis why didn’t you just replace it with a Evergreen EM Replacement Blower Motor the price differences isnt that much. it seems like a lot of extra work just to wire in that motor when you could’ve just unplugged and plugged in new evergreen eM, but I guess some people a $200 difference makes or breaks for the job. You’re the man have a great day buddy.
I just started doing some service self thought over the years. I mainly do installation and new construction. Relays and sequencers throw me on a loop 😅l.
Boy I bet the customer was happy you got it working on the weekend! Good change retrofit. Just curious, was it still under warranty? Or did the customer just opt to fix with PSC? Thanks.
most of the control boards require feedback from the ECM motor to let the unit works, if we put psc motor they are not goone work. the control board knows what is the speed of the motor and keeps going, what do you do with the type of units?
Electronics are a pain, I live in the Cayman Islands and I recomend the 2 stage 18 seer systems, higher seer than that it's a waste of money; specially with Condensing units with boards.
You’re right a communicating motor, or some systems actually adjust torque or airflow by differing the low voltage - those you gotta have an OEM motor.
I thought X13 motors were multi-speed depending upon which of the several 24ac inputs were active. If you route one of those inputs to the contactor, what happens when a different speed is called for?
@@roberts1159 about $20 per month 6 months of the year. About $10 per month the 6 other months average. Where an ECM gets it efficiency from is the use of permanent magnets. We've ran a bunch of in-house tests. The ECM motor, inside the compressor, (aka inverter compressor) is how they achieve 20 plus seer.
@@Bryan-Hensley And the savings is much more depending on the cost of power. Some areas charge as much as 50 cents per kWh so $20 could be an easy $75 a month.
These damn X13 motors remind me if the Cannon engine HP IIP laser printer.... Where as the laser failed from High Humidity... But at least with those it left a tell tail skull and crossbones ☠️ on the PCB... I first encounter this fail with the X13 a number of years ago when I bought a condo with all brand new appliances... Including the HVAC.... I fought that company that installed it and the manufacturer of the AC... But in the end I got the motor replacement under warranty and it's been running flawless ever after... Oh yeah and that damn none compatibly with the Freon and the TXV valve... Pain in the butt
Do those ECM's have a high failure rate? I see a lot of them being replaced by techs? I was told that when the module fails on them, it shuts the whole low voltage system down. Is that true?
the problem with with an ECM isn't the motor itself, but the internal driver required to run it. the motor itself is just coils, rotor, and bearings. just like the construction of an induction motor. the electronics required to run the motor are usually encased in resin and mounted in the endcap of the motors to save space. unfortunately that means that if the electronics fail, the entire module has to be replaced because the electronic components are not accessible. ideally, the motors should come with a seperate watertight unit that can be mounted nearby or even indoors, which can also be opened to access the circuit board inside. that way if there is a problem with the board it can be taken to an electronics tech for repair, rather than just scrapping it and starting from square one. but that just doesn't happen unless you're using an induction motor and a VF drive from a reputable manufacturer
I’ve done this once before but never thought about having to change the stat setting. So you changed it where the stat controls the fan during heat vs the equipment?
Don’t know why you had to cut the wires so close to the plug, it’s not like you are the only one that works on that unit. Not a good thing but you do you.
