Possible Causes

Stuck or open bake/broil relay, Shorted triac controlling elements, Burnt solder joints on EOC

How to Fix / Troubleshooting

Safety first: Disconnect power before removing the rear panel.

  • Visual inspection:
    • Inspect the EOC for burnt areas near the relays or triacs.
  • Element test:
    • Disconnect bake and broil elements and test for continuity (typically 10–40 Ω).
    • If elements are good, the control's switching devices are suspect.
  • Replace EOC:
    • Replace the electronic oven control board if relay/triac damage is evident or E8 persists.
