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
Between the hardness of the supply and summer ambient that sits far above what a catalogue figure assumes, refrigeration here is working at both ends. Scale narrows the fill side while the condenser fights the room temperature on the other.
