GE Oven F3 Error — Temperature Sensor Fault

What Does This Error Mean?

GE oven F3 error means the oven temperature sensor (RTD probe) has an open circuit (F3) or a shorted circuit (F3 on some models means either). Test the sensor with a multimeter and replace it if it reads open circuit or near zero ohms.

Affected Models

GE Electric Range
GE Gas Range
GE Profile Range
GE Café Range
GE JB Series

Common Causes

Failed oven temperature sensor with open circuit
Shorted sensor sending a zero-ohm reading
Sensor wiring burned or disconnected
Physical damage to the probe from contact with bakeware
Control board issue (less common — test sensor first)

How to Fix It

Perform a power reset.

Switch off the breaker for 2 minutes, restore power, and check if F3 returns. A one-time F3 from a voltage transient may clear permanently.
Locate the temperature sensor.

Open the oven door and look at the upper rear wall inside the oven cavity. The sensor is a thin metal probe projecting from the back wall — typically held by two screws.
Test the sensor with a multimeter.

Disconnect the two sensor wires and test resistance. At room temperature (21°C / 70°F), a good GE oven sensor reads approximately 1,000–1,100 ohms. Open circuit (OL) means failed open; near zero ohms means failed shorted. Either confirms replacement is needed.
Replace the sensor.

Remove the two mounting screws, pull the probe out through the oven cavity, and disconnect the wiring from behind the back panel. Install the new sensor, reconnect the wiring, and run a test cycle.

When to Call a Professional

GE oven temperature sensors are inexpensive ($15–$40) and straightforward to replace. The probe mounts to the oven rear wall with two screws and the wiring connector is accessible from behind the back panel.
