Joe for Model Number 66513193K902 Saw your answer to another question about testing if motor is getting 120V. I'm trying to determine if motor or control board is at fault for main pump not operating while diverter motor works fine. The wiring diagram on service technician sheet for this model shows P1 and P2 eventually connecting to line neutral (P1 is through motor relay on control board), while 120V line voltage should be on P3. P3 is fed from spliced connection from motor fuse, with the other splice supplying diverter motor. The motor fuse is supplied from pilot relay on control board and ultimately from line voltage. I don't understand why you indicated that testing across P1 and P2 should show power, unless the pins are labeled differently on different models. I see 120V on P3 (and diverter works) and not on P1 and P2. Seems like my motor is getting power correctly from P3 and therefore the motor is at fault - is that correct interpretation? Or could it still be bad motor relay on board? Or the motor communication/data coming from board?
Answer Joe, Unfortunately, we do not have access to the wiring diagram for this unit but if you were to test at the motor and see if there is 120 Vac getting to it. If there is power to the motor and the motor is not running then the issue will be a faulty motor. Read More... Answered by AppliancePartsPros.com | Monday, March 23, 2020
