Hisense Refrigerator Error Code E2
Freezer temperature sensor fault
Common Causes
- 1Freezer NTC sensor open or shorted
- 2Sensor iced over from a defrost fault
- 3Wiring damaged
- 4Connector fault at the board
Step-by-Step Troubleshooting
- 1
Unplug the refrigerator and remove the freezer rear panel to reach the sensor on the evaporator
- 2
Check for heavy frost encasing the sensor, which points to a companion defrost fault
- 3
Measure the freezer NTC resistance cold — an open reading confirms a bad sensor
- 4
Inspect the wiring from the sensor along the evaporator to the board connector
- 5
Replace the freezer sensor, and if it was iced, investigate the defrost circuit as well
Pro Diagnostic Tip
A freezer sensor buried in frost usually means the defrost system also failed. Fixing only the sensor while ignoring the frost cause leaves you back with E2 within weeks.
