Lee February 01, 2019 for Model Number ZISB420DRI After a full defrost cycle and restart everything operates ok, after approx. 2 weeks temp starts rising in FF and Freezer, frost accumulates above ice maker on fins. Is this a sensor problem and which one do I need to replace?
1 Answer Lee, you may want to check to ensure that there is not an air leak through the door gaskets. You will also want to check all of the thermistors as it is possible that one of them may have failed and is causing the unit to try to cool too much, causing the evaporator to freeze up. If the thermistor is an open circuit, it has failed. At 5 degrees Fahrenheit, the thermistor should read 36.4k ohms, 14 degrees should be 27.6k ohms, and -4 degrees should be 48.4k ohms. More than likely one of the freezer thermistors have failed and is causing the unit to freeze up. If you see frost congesting the evaporator and the thermistors do not read a proper resistance, then the thermistor is the cause. Read More...
Alexander July 31, 2015 My GE refrigerator does not hold temperature freezer temperature fluctuate between -6 to 10 degree F the refrigerator temperature fluctuate between 34 to 40. Food is being spoiled. I changed the thermostat but did not fix the problem. Can you tell me what could be the problem and what part I should change to fix it
