Trane Motor Module


I have a trane system about eight years old. It has a variable speed motor. The motor is not working. I had a neighbor who used to do AC work check it out for me. He said that either the motor or the module is bad. He said that they are very expensive and I would be better off with a new system. Can anyone please give me a rough Idea what it would cost to replace either the module or the motor?

It all depends on the model. Roughly bout $400-650 depending on parts nd labor cost. A whole new system would be wayyyyyy more expensive!

Depends if its the motor, or the module. The module is not real expensive, the motor is. Both are OEM parts only.

At 8 years of age, its probably a lot better to just repair then to replace the furnace.

Module loses programming most of the time , try to test out with TecMate tool or something similar - install new module with VZPRO next time. Surge protection device protects against voltage spikes.

OEM Motor with 1-year warranty - $ 260 to $300 depending on model #
OEM Module with 1-year warranty - $ 243 to $363 depending on model #

Not very labor intensive. Air Handler or system change...very labor intensive. Unit may have a 10-year warranty though? Would only be able to determine with serial # .

For what it's worth....

There have been a ton of these motors replaced due to faulty wiring harnesses. Water can drip onto them or vibrations make them come loose.

I have put several "failed" ECM motors on a Techmate and prooved fine. The wiring harnesses were replaced and the modules and boards are fine.

This seems to still be common in 3-5 ton carrier/Bryant with Emerson motors.

Btw wiring harness should be changed anyways as a good service practice according to Emerson, and they run about $20

To dig deeper, if the module did in fact go bad, they usually have some pretty nice burns visible on the circuitry where they remove from the motor.

Check your warranty. I personally no longer offer ECM controls off of motors. The modules are matched to the motor, o have not had awesome luck with swapping modules on an old burnt/failed module (about 12 or so in the last 5 years)

.x2 on the wiring harness. The motor can be tested to see if it good, but there are carbon contact points that do wear down.
There is an aftermarket version of the setup.
