ReplyThanks 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.

There actually called torque taps and there 24 volts that are set/programed by the mfg. for the furnace/air handler the motor is installed in, it's not really recommended that the tech play with the torque taps.Originally Posted by Brent Ridley

Thats good to know, I never have tried that, but in Houston it's a petty good chance you will always find the part, so I just pull the motor and go get another one.

Rheem /Ruud has a 3 phase pachage unit that uses a single phase X13 blower motor. And they fail.

Yes, new part failures are becoming more common everyday, now Carrier is going to the LG compressors, guess pretty soon we wont have time to do our everyday service calls, for all the warranty calls we will have.

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...

On an X13 motor, my supply house will not accept just the module, they want to whole motor for warranty, unless something has change in the past two weeks.

It is my understanding that the new carrier fx series airhandlers do not use the x13 anymore? That carrier sticks some made in china pos in its place. Anyone? I know the fv is ECM 3.0

We've replaced several of them. But I've found zero correlation between X13 failures and static pressure. Just my personal observation. The last two that I replaced were actually running low ESP's, as in 0.3-0.4". There was rust on the shafts though, indicating that the problem was probably condensation. Dehumidification mode may have been responsible for that. I've started ignoring the instructions and using the next lower speed tap for low cooling (dehumidification) speed rather than the "lowest speed that doesn't cause evap coil freezing." There were also some X13's that were just defective. There was a bulletin issued and it was posted in this forum somewhere. Something about a component in the motor module that would overheat IIRC.

That 3 phase rheem with single phase x-13 is whats giving me grief right now it has the speed taps and the silicone goop in the bell. I get there and blower is dead turn breaker off to chek connections in disconnect alls ok turn breaker back on now all starts working for four to six hours or all day. going back out tomorrow mean while customer is turning breaker off and on should it stop running. Unit does not trip breaker. Its just a way to reset module?

George,
Confirm correct voltage. Ohm out the motor. If the motor is good, replace the module.
Mr. Bill,
Carrier is now paying warranty labor for module replacements. I'm not sure what brand your talking about.

Thanks Mr. Bill. Unit is a Rheem 3 Phase with a single phase gentec x-13 there is also a Emerson comfort alert commercial diagnostics contraption on the unit to add to the wiring nest . Any how I'll be up on that roof tomorrow, forgot to mention with a can of wasp spray there is a giant wasp nest in disconnectGeorge

Ruud, it sure would be nice if Ruud started paying labor for module replacements, maybe they will "someday".

X13 is good for scrap metal, the end.
