Possible Causes
Line voltage too low or too high, Loose terminal block connections, Incorrect wiring (208V vs 240V), Shared circuit overload
How to Fix / Troubleshooting
Safety first: Turn off the breaker before opening the junction box or terminal block.
- Measure voltage: Have a qualified person measure the voltage at the cooktop's terminal block. It should match the rating on the Summit nameplate (typically 208–240V).
- Inspect connections: Tighten all terminal screws at the cooktop and in the junction box. Look for heat discoloration or melted insulation.
- Dedicated circuit: Ensure the cooktop is on a dedicated circuit of the correct amperage. Remove other loads from the same circuit.
- Utility issues: If house voltage is unstable, contact your power utility or an electrician.
