What Does Error F4 Mean?

The GE Oven F4 error code indicates a fault with the temperature sensor, leading to inaccurate temperature readings and inconsistent cooking results. This error occurs when the control system detects abnormal resistance or a short in the temperature sensing circuit, preventing it from receiving valid data. Common symptoms include the F4 code appearing on the display during operation, the oven shutting off unexpectedly, or the control becoming unresponsive. Addressing this issue typically involves checking the temperature sensor and its wiring for defects.

Common Symptoms:

  • F4 code appears on display when oven is powered or during heating cycle
  • Oven may shut off or refuse to start heating
  • Oven temperature displays or control becomes unresponsive

Possible Causes

  • Shorted or defective oven temperature sensor (high)
  • Wiring issues between sensor and control board (intermittent short/connection fault) (medium)
  • Control board malfunction interpreting sensor input (medium)

How to Fix Error F4

DIY Fix Basic user checks and reset

  1. Turn oven off and shut off power at circuit breaker for 1–2 minutes then restore
  2. Check if the F4 code clears on restart

Technician Only Diagnose and repair temperature sensor circuit

  1. Disconnect power to oven
  2. Access oven temperature sensor (typically at back wall of oven cavity)
  3. Measure sensor resistance with a multimeter at room temperature
  4. Inspect wiring harness between sensor and control board for shorts, chafing, or loose connections
  5. Replace sensor if resistance is out of spec or wiring is damaged
  6. If resistor and wiring are good, test and potentially replace the electronic range control

Parts needed: Oven temperature sensor, Wiring harness/connectors, Electronic range control (ERC), Multimeter for diagnostics

🛑 When to Call a Pro:
  • If you are not confident or experienced with internal electrical diagnostics
  • If power-off reset and basic sensor checks do not resolve the fault
  • If wiring or control board appears damaged or uncertain
