What Does Error F4 Mean?

The Haier oven error F4 indicates a malfunction in the temperature sensor circuit, which can result in inaccurate temperature readings or the oven failing to heat properly. This issue may cause the oven to shut off unexpectedly during cooking. Common causes include a shorted or faulty temperature sensor or damaged wiring leading to the sensor. Addressing this error typically involves inspecting and potentially replacing the temperature sensor or related wiring.

Common Symptoms:

  • Oven displays F4 on the control panel
  • Oven may shut off mid-cycle
  • Temperature may be inaccurate or the oven may not heat correctly

Possible Causes

  • Shorted or faulty oven temperature sensor (medium)
  • Pinched or shorted wiring harness leading to the temperature sensor (medium)

How to Fix Error F4

DIY Fix Basic power reset and visual check

  1. Turn off the oven and disconnect from power at the breaker or unplug.
  2. Wait a few minutes and reconnect power to see if the error clears.
  3. Visually inspect the oven interior for obvious physical damage or debris near the sensor area.

Technician Only Temperature sensor and wiring inspection

  1. Disconnect power to the oven at the circuit breaker.
  2. Remove the oven’s back or access panel to inspect the temperature sensor and its wiring harness.
  3. Check the temperature sensor resistance with a multimeter; replace the sensor if readings are out of specification.
  4. Inspect wiring harness for pinched, damaged, or shorted wires and repair or replace as needed.
  5. If sensor and wiring are good but the error persists, inspect the main control board’s sensor input circuit and replace it if necessary.

Parts needed: Oven temperature sensor (RTD probe), Wiring harness, Main control board (if sensor input circuit is damaged)

🛑 When to Call a Pro:
  • If you are uncomfortable working with electrical components or the error persists after basic resets
  • If inspection reveals burnt wiring, corrosion, or control board damage
