Possible Causes

Incorrect supply voltage (one leg missing), Loose terminal block connections, Burned power cord or wiring, Internal short on power board

How to Fix / Troubleshooting

Safety: This involves live voltage. If you are not experienced with electrical testing, contact a qualified technician.

Checks (with power OFF first):

  • Turn off the breaker and pull the oven out enough to access the terminal block or junction box.
  • Inspect all connections for tightness, discoloration, or melted insulation.
  • Repair or replace any burned wires using high-temperature wire and proper connectors.

Voltage verification (for qualified persons only):

  • With power ON, measure voltage between L1–L2 (should be ~240 VAC in North America) and L1–N / L2–N (should be ~120 VAC each).
  • If one leg is missing or low, correct the supply at the breaker panel or junction box.

If supply is correct but E08 persists:

  • The power/relay board or main control board may have an internal short and should be replaced.
