GE oven shows F8 and may not heat properly or may shut off

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

Failed oven temperature sensor, Stuck bake or broil relay on control board, Poor airflow around oven

Safety first: Turn off power and allow the oven to cool fully before working.

Check sensor: Test the oven temperature sensor resistance at room temperature (~1080 Ω). Replace if out of range.
Inspect control relays: With power disconnected, visually inspect the EOC for burned or welded relay contacts. If the bake or broil relay appears damaged, replace the control board.
Verify installation: Ensure the oven is installed with proper clearance and that cooling vents are not blocked by cabinetry or insulation.
