Hisense Refrigerator Error Code E1
Refrigerator (fresh-food) temperature sensor fault
Common Causes
- 1Fresh-food NTC sensor open or shorted
- 2Sensor wiring damaged
- 3Connector loose at the main board
Step-by-Step Troubleshooting
- 1
Unplug the refrigerator and locate the fresh-food compartment sensor clipped near the interior wall or air duct
- 2
Measure the NTC sensor resistance at room temperature — an open or near-zero value confirms failure
- 3
Inspect the sensor lead back to the main control board for pinch damage behind the liner
- 4
Reseat the sensor connector at the board and check for corroded pins
- 5
Replace the fresh-food temperature sensor if it reads out of range
Pro Diagnostic Tip
With E1 active the board defaults to a fixed run pattern, so the fridge often stays roughly cold — do not be misled into thinking nothing is wrong. The compartment will drift off-setpoint over a day.
