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.
