How to Fix / Troubleshooting
Safety first: Disconnect power at the breaker before opening any panels.
- Power cycle: Turn off the breaker for 5–10 minutes to fully discharge the electronics, then restore power and test.
- Check for moisture/spills: If liquid has seeped around the control area, allow the unit to dry completely for 24 hours before retesting.
- Inspect ribbon cable (for qualified persons):
- Remove the cooktop from the counter and open the control housing.
- Reseat the flat ribbon cable between the touch control and main board, ensuring it is fully inserted and locked.
- Look for corrosion or burnt spots on the connectors.
If E7 persists, either the touch control module or main PCB is defective and should be replaced by a professional.
