GE Oven Error Code F5-E1

The F5-E1 code means the control board detected an over-temperature condition in the lower oven cavity during a cooking operation. The oven shuts down to prevent damage when this threshold is exceeded. The fault points to the lower cavity temperature sensor, its wiring, or in some cases an actual thermal issue inside the oven. Diagnosing it requires checking the sensor connection and measuring its resistance.

No, you should not continue using the oven until the fault is resolved. The F5-E1 code indicates the oven detected an unsafe temperature level in the lower cavity, and operating it in this condition could damage internal components or create a safety hazard. Avoid using the oven until the sensor, wiring, and cavity airflow have been inspected and cleared.

Repair costs vary depending on the cause. A replacement lower cavity temperature sensor typically costs between $20 and $60 for the part, making it one of the more affordable fixes. If the control board requires replacement, parts alone can range from $150 to $350 or more. Adding professional labor, total repair costs commonly fall between $100 and $450 depending on the component involved and your location.

A knowledgeable DIYer can perform the initial diagnostic steps, including inspecting the sensor wiring connector and measuring the temperature sensor's resistance with a multimeter. If the sensor resistance is out of range at room temperature (approximately 1080 ohms is the expected value), replacing the sensor is a manageable repair. However, if the control board is the cause, that replacement is more involved and may be better handled by a technician.

Resetting the oven by cutting power at the breaker for a few minutes may temporarily clear the code, but it will return if the underlying cause is not repaired. If the temperature sensor is faulty or the wiring connection is loose, the fault conditions will reappear during the next cooking cycle. A reset is only useful as a preliminary step to confirm the code, not as a fix.
