Which fan motor - inside the freezer or the condenser fan underneath?
THese are a little difficult to diagnose but basically there should always be 12 volts to the fan motor and then a signal from the board ( also 12 volts ) turns on the transistor in the motor at different pulses to determine which speed to run the motor . I'll get you some information to check this motor but for now get a 9 volt battery and three jumper wires of some type ( the kind with alligator clips on each end would be ideal but some wire to make connection from the battery to the motor ) I'll be back in about 45 minutes and we'll go from there.
This info tells me that the voltage seems to be incorrect. The motor does run with an external battery.
What control circut drives thsi motor?
We replaced the main circut board twice thinking it was a defective new board
