- Ensure no buttons or programming buttons were pressed accidentally triggering a defrost mode
- Power‑cycle the refrigerator by unplugging it for ~5 minutes, then plug back in and allow several hours to reach temperature
Technician Only Diagnosis and control board evaluation
- Run diagnostic mode per manufacturer service manual to confirm fault codes
- Inspect control board and related wiring for faults or failed components
- Test thermistors/sensors related to defrost control to exclude erroneous readings
- Replace the control board or user interface board if confirmed as root cause
Parts needed: Control board (user interface), Thermistors/sensors
