F3 error code, oven will not heat or stops mid-cycle.

Safety: Disconnect power before testing or replacing the sensor.

• Access sensor: Inside the oven, locate the sensor probe on the rear wall. Remove its mounting screws and gently pull it forward to expose the connector.
• Check connection: Ensure the sensor plug is fully seated. If it was loose, reconnect, restore power, and test.
• Measure resistance: With the sensor disconnected and at room temperature, measure resistance with a multimeter. A typical GE sensor should read ~1080 Ω at 70°F. If reading is infinite (open) or wildly off, replace the sensor.
• Inspect harness: If the sensor tests good, trace the harness to the control board for breaks or burns. Repair or replace the harness if damaged.
• Replace sensor: Install a new GE-compatible RTD sensor, secure with screws, and reconnect wiring. Test a bake cycle.
