Possible Causes
Low or high line voltage, Loose power connections at terminal block, Damaged power cord, Faulty EOC power supply circuit
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker. High voltage is present; if you are not experienced, contact a professional.
- Inspect terminal block:
- Remove the rear cover at the power cord entry.
- Check for loose screws, burnt wires, or melted plastic.
- Tighten connections and replace any burnt wiring or the terminal block if damaged.
- Verify line voltage:
- Use a multimeter to confirm 240 VAC (or appropriate voltage) at the terminal block.
- If voltage is out of range, contact an electrician.
- Control board:
- If supply is correct but E5 persists, the EOC's internal power supply may be faulty; replace the electronic oven control board.
