What Does Error F3 Mean?
The F3 error code on a Magic Chef oven indicates a malfunction in the temperature sensor circuit, which may be open or shorted. This often leads to erratic temperature readings, causing the oven to fail to heat properly and shut down unexpectedly during cooking cycles. Inspecting the oven temperature sensor (RTD) and its connections to the control board is essential for resolving this issue.
Common Symptoms:
- Oven will not heat
- Oven shuts down shortly after starting a cycle
- Error code displayed when starting bake or heating
Possible Causes
- Open or shorted oven temperature sensor (RTD) (high)
How to Fix Error F3
DIY Fix Basic checks and power cycle
- Turn off oven and disconnect power at breaker or unplug.
- Wait a few minutes, then restore power to see if the error clears.
Technician Only Inspect and test oven temperature sensor and wiring
- Disconnect power at the breaker.
- Access inside the oven cavity and locate the temperature sensor (usually a thin metal probe on the back wall).
- Disconnect the sensor wiring harness and visually inspect for corrosion, breaks, or loose connections.
- Use a multimeter to measure the sensor resistance at room temperature; verify it matches expected range.
- If sensor is open/shorted or outside expected range, replace with a compatible sensor.
- Inspect and, if needed, repair or replace wiring harness or connectors between sensor and control board.
- Reassemble and test oven operation.
Parts needed: Oven temperature sensor (RTD), Wiring harness/connectors
- If error persists after inspecting/replacing the sensor and checking wiring
- If resistance measurements are inconclusive or unfamiliar with safe diagnostic procedures
