Thread: x-13 evap motors...

It has that black rubber matting around the resistor. You can't even access the base on the circuit board without somehow removing that matting.
And, I've never seen a burnt resistor on the X13 only ECM 2.3's.

X13 motors are constant torque and operate at set speeds.
ECM 2.3 modulate speeds. Truely variable.
They're not the same.

We find about 1 bad x13 every 2 weeks. It's getting to be a pain and customers aren't very happy about it. We've only had a couple bad out of our installations but lots from service calls on other equipment, most of the time it's bc of inadequate ducting and/or condensation.

By set speeds, I meant you have speed selection terminals on the motor.
Yes. It is constant torque.

Thanks for the clarification Mr. Bill.
The only time I've ever changed a tap is on a failure. Once or twice, I've changed the tap and gotten the motor operational until a replacement arrived.

I had two recent classes that touched on this. One was a RSES with a Nordyne Rep., the other a Carrier distributor with a class specifically dedicated to troubleshooting ECMs. They both swore up and down that the issues were becoming less, and in my limited experience in kinda seems so. It's been many a week since I've had to deal with one, and we've installed a boatload of 'em.
However...you can't ignore the fact that the reason they keep having these classes is because there was/is a huge issue and they are sick of giving out warranty motors and modules together - when they well know by now it is the modules that are the culprit as much as 90% of the time.
I just got yet another RSES bulletin in the mail over the weekend concerning this very issue. As noted above, the X13s now have a thick rubber matting protecting the module circuitry as they figured out that moistue really messes with these things.
I have no clue as to how they are attempting to deal with the power surge issue, other than to suggest additional surge protection...
