What Does Error E1 Mean?

The Hisense refrigerator error E1 signifies a fault in the temperature sensor circuit, particularly related to the freezer compartment thermistor. This error often results in incorrect or fluctuating temperature readings, leading to inadequate freezing performance. If your display shows E1, it indicates that the freezer may be too warm or unable to maintain the set temperature, prompting further investigation or repair.

Common Symptoms:

  • Display shows E1 while the freezer temperature is incorrect or fluctuating (often freezer too warm or unstable) turn0
  • Fridge or freezer not maintaining set temperatures relative to display readings

Possible Causes

  • Freezer compartment thermistor (temperature sensor) fault or open/short condition (medium)
  • Disconnected, damaged, or moisture-intruded wiring harness between freezer sensor and control board (medium)

How to Fix Error E1

DIY Fix Basic diagnosis and reset

  1. Unplug the refrigerator from power for 5–10 minutes to attempt to clear transient errors and reset the control board.
  2. Observe if the E1 code returns after restoring power.

Technician Only Inspect and test the freezer temperature sensor circuit

  1. Access the freezer compartment interior and locate the thermistor (temperature sensor).
  2. Visually inspect the sensor and its wiring harness for loose connections, breaks, or moisture intrusion.
  3. Use a multimeter to measure the thermistor’s resistance and compare it to expected values at known temperatures.
  4. Replace the thermistor if readings are open, shorted, or out of expected range.
  5. If sensor and wiring are good but the error persists, inspect the main control board’s sensor input channel for faults.

Parts needed: Freezer thermistor (temperature sensor), Wiring harness (as needed), Control board (if required)

🛑 When to Call a Pro:
  • If the error persists after basic reset and preliminary inspection
  • If you are uncomfortable opening panels or lack tools for safe diagnosis
  • If there is evidence of ice/water damage or electrical issues beyond simple sensor replacement
