GE Error Code F4
Shorted oven sensor
Common Causes
- 1Sensor wire short circuit
- 2Damaged sensor insulation
- 3Sensor element failure
Shorted sensor wiring can damage the ERC board over time. Replace promptly to avoid cascading failure to the more expensive control board.
Step-by-Step Troubleshooting
- 1
Power off at breaker
- 2
Disconnect oven sensor connector at the back of the range
- 3
Measure sensor resistance — shorted sensor will read near 0 ohms or very low (<200 ohms)
- 4
Inspect sensor wire insulation for damage where it passes through oven cavity wall
- 5
Check for wire contact with metal oven frame causing a ground short
- 6
Replace sensor if element is shorted; repair wiring if insulation damage is the cause
Pro Diagnostic Tip
A shorted sensor causes the ERC to read a falsely high temperature, so the oven may refuse to heat or heat erratically. If resistance reads 0 ohms with sensor disconnected from wiring, the sensor element itself is shorted. If it reads normal when disconnected, the wiring has a short to ground.
You Might Also Notice

- •Erratic temperature readings on display
- •Oven acts like it is at max temp when cold
