Box does not defrost if I unplug the defrost clock and jump L1 to heater which is terminal #4 to terminal #5 and then plug in box to power. It should defrost if defrost heater and defrost thermostat are good correct? I am a technician.
ANSWER Hello Allan,
This is the old Amana control. You don't short terminals on this control since if you short terminals on this configuration, you can too easily fry the microprocessor.On this configuration you press the door switch in 6 times in 5 seconds. If the control is operational, the unit will go into the defrost cycle. As per the manufacturer, the door switch presses have to be slow enough to be, in their own words, "intentional". Shorting wires together on this model as per the manufacturer is "asking for trouble".
