Call a professional if you're uncomfortable working with electrical components, if the wiring harness is damaged and needs extensive repair, or if the error persists after sensor replacement as this may indicate a control board failure.

Frequently Asked Questions

What does F4 error code mean on a GE oven?
F4 error code indicates a short circuit in the oven temperature sensor. This sensor monitors internal temperature, and when it fails, the oven shuts down for safety and cannot regulate heat properly.
Can I still use my GE oven with F4 error code?
No, you should not use the oven with F4 error code. The faulty temperature sensor means the oven cannot accurately monitor or control temperature, creating potential safety hazards and poor cooking results.
How much does a GE oven temperature sensor cost?
A replacement GE oven temperature sensor typically costs $25-60 depending on your specific model. It's a relatively inexpensive part that most homeowners can replace themselves.
How do I reset my GE oven after fixing F4 error?
After replacing the temperature sensor, simply restore power to the oven. The error code should clear automatically. If F4 persists, turn the oven off for 5 minutes, then back on to reset the control system.
What causes GE oven temperature sensor to fail?
Temperature sensors typically fail due to age, heat cycling, moisture exposure, or physical damage. Normal wear from repeated heating and cooling cycles eventually causes the sensor element to break down or short circuit.
