GE Monogram Refrigerator Thermistor Fault
Refrigerator Thermistor Fault is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
A drifted or failed temperature sensor
These components measure cavity or cabinet temperature and can fail gradually rather than all at once.
A damaged sensor wire or connector
Physical damage or a loose connection can produce the same symptoms as a failed sensor.
A control board misreading a healthy sensor
Less common, but worth ruling out if a replaced sensor doesn't resolve the issue.
Local conditions that matter here
This is a marine climate with a long cool wet season, so a cold door seal here rarely gets a chance to dry between cycles. A gasket that lives damp perishes and loses its set rather than tearing, which passes a visual check and still leaks — which is why so many of these arrive reported as a unit that runs constantly for no visible reason.
