Haier Refrigerator Error Code F3 — Refrigerator Compartment Sensor Error
What this means
Error code F3 on Haier refrigerators indicates the main temperature sensor (thermistor) in the fresh food compartment has returned an abnormal reading. This sensor monitors the air temperature to control compressor and fan operation. If it fails, the refrigerator cannot maintain the correct temperature, potentially causing food spoilage. The sensor may read open, shorted, or drift out of calibration over time.
Step-by-step fix
3 stepsReset the refrigerator
Unplug for 10 minutes and plug back in. If F3 clears and does not return within 24 hours, it was likely a temporary glitch.
Monitor the refrigerator temperature with a standalone thermometer after the reset to verify it is maintaining 37°F (3°C).
Locate and test the temperature sensor
The sensor is usually mounted inside the refrigerator compartment, often behind a plastic cover near the top or side wall. Remove the cover, disconnect the sensor, and test with a multimeter. At room temperature (~72°F), expect approximately 10,000–15,000 ohms.
Place the sensor in a glass of ice water — the resistance should increase significantly. If it does not change, the sensor is defective.
Replace the sensor
Install the new sensor in the same location, reconnect the wiring, and replace the cover. Plug the refrigerator back in and monitor for 24 hours to confirm F3 does not return.
After replacing, adjust the temperature setting to your preferred level — the new sensor may require the fridge to recalibrate.
When to call a professional
If the sensor reads correctly but F3 persists, the control board or its wiring harness may be faulty. A certified Haier technician should diagnose the control system.
