F3E2 error, oven temperature reading is erratic or oven cycles incorrectly

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

Partially failing oven sensor, poor sensor connection at control, control misreading sensor signal

Safety: Turn off power before testing.

Check sensor resistance at multiple temps: Measure at room temperature and again after gently warming the sensor (e.g., with a hair dryer). Resistance should increase smoothly; jumps or opens indicate failure.
Inspect connector: Clean and reseat the sensor connector at the control board.
Verify harness continuity: Check continuity from sensor plug to control board plug.

If sensor and wiring test good, the control board may be misinterpreting the signal and should be replaced.
