Fault Diagnosis · coolinghigh
Temperature Fluctuations
Unstable temperatures swing between too warm and too cold, risking food safety and indicating a control or sensor instability.
Common Symptoms
- Inconsistent readings
- Food spoiling intermittently
- Display temperature drifting
- Frost then thaw cycles
How we diagnose it
We log temperature over time, test sensor accuracy, and assess the control board's modulation of the compressor and damper.
Common causes
Drifting temperature sensor
Unstable control board
Damper actuator fault
Defrost cycle misfire
Door seal leak
Refrigerator types affected
