What Does Error E1 Mean?

The Haier oven E1 error code indicates a malfunction in the temperature sensor, which may cause inaccurate temperature readings or prevent the oven from preheating. This could be due to the sensor being open, shorted, or out of range. To resolve the issue, inspect the temperature sensor and its connections. If the problem persists after a basic reset, further diagnostics may be needed.

Common Symptoms:

  • Oven displays E1 on control panel
  • Oven may not heat or start properly
  • Temperature readings not correct or sensed

Possible Causes

  • Temperature sensor fault (medium)
  • Loose or poor connection at temperature sensor or control board (low)

How to Fix Error E1

DIY Fix Basic checks and power reset

  1. Turn off and disconnect oven from power for safety.
  2. Wait a few minutes and reconnect power to see if E1 clears.
  3. Ensure oven door is fully closed and controls are properly set before re‑starting.

Technician Only Inspect/replace temperature sensor

  1. Power off and isolate the oven from mains.
  2. Remove required panels to access the internal temperature sensor and its wiring.
  3. Check sensor resistance against Haier specifications at room temperature.
  4. Replace sensor if resistance is out of spec, and verify sensor wiring/connectors are secure.
  5. Test oven operation after replacement.

Parts needed: Temperature sensor (NTC thermistor)

🛑 When to Call a Pro:
  • If E1 persists after sensor/wiring checks and basic reset
  • If there is evidence of wiring damage or control board issues
  • If you are not comfortable performing internal diagnostics
