Maytag Oven F8E0 — Control Board Power Supply Fault

Maytag Oven · Error code F8E0

What F8E0 Means

The control detected a fault on its internal power supply rail. The control cannot operate reliably and shuts down functions.

Symptoms

  • F8E0 on display
  • Random reboots of the control
  • Oven will not start

Common Causes

1
Failed control board power supply

A regulator or capacitor on the EOC has failed.

2
Incoming voltage problem

Low or unstable line voltage caused the rail to droop.

3
Wiring harness short loading the supply

A shorted load on a sensor or switch line is dragging the rail down.

How to Fix It

  1. Verify 120V leg-to-neutral and 240V leg-to-leg at the oven terminal block.
  2. Disconnect power and inspect all harnesses for damage.
  3. Unplug non-essential loads (oven light, door switches) and retest.
  4. If supply still fails with loads removed, replace the electronic oven control.
