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.
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.
An x13 motor is no less a "true ECM" than a GE 2.3.
I haven't found any X13 failures myself, is this a regional thing?
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?
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 disconnect George
