F1E5 displayed, oven may lock up or not start cycles

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

Internal control board failure, power surge damage, unstable line voltage

Safety: Turn off power at the breaker.

Power reset: Leave power off for at least 10 minutes to fully discharge the control, then restore.
Check supply voltage: Verify 240 VAC (or 208 VAC where applicable) at the terminal block with a multimeter. Low or fluctuating voltage can cause logic errors.
Inspect control: Remove rear cover and inspect the control board for burn marks or damaged components.

If F1E5 returns consistently, replace the electronic oven control board.
