Evaporator motor does not run. The motor is #AP3797248. I put 12 volts to the motor and no results. The motor plug has 4 wires and the frig plug has 3 wires, white,red, and pink. I have 13.53 volts across the white and red wires and 3.67 volts across the white and pink wires,but the voltage goes down to zero after about 15 seconds on the white to pink connection. About an hour later I measured voltages again and got 8.87 volts across white and red and 8.82 volts across the white and pink wires. I know the motor is bad, but is there anything else that could be wrong?
