Customer Questions and Answers for Refrigerator Electronic Control Board by Whirlpool

Hello Pete, The icemaker will only show 120vac when the icemaker is cycling. The thermostat on the icemaker will allow power to pass through and circuit will meet up when the thermostat is closed. You can jump start icemaker by inserting a jumper wire between t and h on the motor module. The light switch will also need to be closed. When you jump t to h and the light switch is closed the unit should start cycle. Once it is in a cycle if you check M to N then you should have 120 vac. When it gets to about the 11:30 position if you check v to n you should get 120 vac for a small length of time. If the icemaker does not cycle when jumping t to h then you have a bad module. If it does operate then the thermostat on the icemaker is faulty. You can also check the icemaker thermostat when cold by removing the module and doing a continuity check. If closed then it is good. Check middle 2 terminals for thermostat. Check outer 2 terminals for heater continuity.
