Steve for Model Number 79574043412 How can I determine whether the fan motor or the electronic control board needs to be replaced? Thanks for your help.
Answer Hello Steve, this fan motor runs on 12vdc supplied by the control board, the fan motor cannot be tested separately with a multimeter, you would need to power it externally with a 12vdc power supply. In cases like this, the motor (load) is replaced first in case it is faulty and possibly has damaged the control board circuit, if the new motor still does not run the control board is replaced next. You can also check for 12vdc from the control at the motor with the motor installed in the ref. Read More... Answered by AppliancePartsPros.com | Tuesday, February 23, 2021
