Display shows F13 and oven temperature display may be inaccurate or blank.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Corrupted EOC calibration data, Faulty temperature sensor, Software glitch after power surge

Safety first: Turn off power before removing panels.

Steps:

Power reset: Turn the breaker OFF for 5 minutes, then ON. Test oven operation.
Sensor test: Verify oven sensor resistance at room temperature (~1050–1100 Ω). Replace if out of spec.
Recalibrate: Some Magic Chef models allow temperature calibration via the user menu (e.g., adjust +/− 35°F). Follow the user manual to recalibrate.
Replace EOC: If F13 persists, replace the EOC.

Note: Always verify actual oven temperature with an oven thermometer after repairs.
