What Does Error E3 Mean?

The Haier oven E3 error code signifies a communication fault between the temperature sensor and the control board, leading to issues such as inconsistent heating, erratic temperature behavior, or the oven failing to start. This malfunction can be caused by loose or oxidized sensor connections, or a faulty control board. Addressing this issue promptly is essential for ensuring optimal oven performance.

Common Symptoms:

  • Oven displays E3 on the panel
  • Oven may not heat properly
  • Erratic temperature behavior or inability to start cycles

Possible Causes

  • Communication fault between function selector or sensor and control board (medium)
  • Loose, oxidized, or intermittent sensor harness connections (medium)

How to Fix Error E3

Technician Only Inspect and repair sensor and control connections

  1. Disconnect power at breaker.
  2. Open control panel to access sensor wiring harness and connectors.
  3. Inspect connectors for oxidation, loose pins, and secure connections.
  4. Perform continuity testing on sensor leads to the control board.
  5. Replace harness or sensor if continuity is poor or connectors are damaged.
  6. If wiring and sensor are good, test control board sensor input circuitry and replace control board if necessary.

Parts needed: Sensor wiring harness, Temperature/function selector sensor, Control board

🛑 When to Call a Pro:
