Not cooling. Alarm going off ?
ANSWER Hi. Is there any frost on the back wall of the freezer? Advance the defrost timer part # 297318010 in the back of the lower cabinet to the Ist heavy click. Timer contacts close between contacts 2 and 4 to send the voltage to the heater. This activates the defrost heater through the normally closed defrost thermostat part # 297216600. If the heater part # 216608500 does not come on then remove the back wall of the freezer and test for 120 vac on one of the incoming defrost thermostat leads -to-ground. If it is there and not out of the other side lead of the thermostat then it is not closed (in temperatures below 14°). If so then ohm out the heater for closed continuity as it need to have resistance value of 11-18 ohms. If the timer turns hard then replace it. It turns very easy in small increments and quickly passes from the first heavy click(defrost begins), to the last 2nd heavy click -terminating 25 minutes defrost time length. This is a usual NO-COOL. Make sure the compressor runs as the temperature is in the mid position. Thank You.
