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.
These components measure cavity or cabinet temperature and can fail gradually rather than all at once.
Physical damage or a loose connection can produce the same symptoms as a failed sensor.
Less common, but worth ruling out if a replaced sensor doesn't resolve the issue.
Based on symptoms like this, these are the components our technicians check first. The exact part depends on your model and what we find during diagnosis.
Most cases like this are fine to schedule within a day or two, though it's worth having looked at before it gets worse.
