Possible Causes
Low or high line voltage, Loose power connections at terminal block, Failed power supply board, Faulty main relay
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before accessing the terminal block or internal boards.
- Verify supply voltage: Have a qualified person measure voltage at the cooktop terminal block. It should match the rating on the data plate (commonly 208–240 V for electric cooktops).
- Inspect terminal block: Check for loose screws, burnt wires, or melted plastic. Tighten connections and replace damaged parts.
- Check wiring harness: Inspect the harness from the terminal block to the power board for damage or loose connectors.
- Replace power board: If supply voltage is correct and connections are solid but E5 persists, replace the main power board or induction power module as specified for your model.
