Possible Causes
Failed on/off switch contacts, Broken wire between switch and heating block, Faulty safety thermostat, Loose spade connector
How to Fix / Troubleshooting
Safety: Disconnect from mains power before opening the unit.
- Check switch operation: Verify that the switch clicks positively. If it feels loose or mushy, suspect internal failure.
- Access wiring: Remove the base cover to expose the wiring from the switch to the heating block and thermostats.
- Inspect for breaks: Look for broken, burned, or disconnected wires. Repair or replace damaged wiring using high-temperature-rated wire and proper connectors.
- Test switch and thermostats: Use a multimeter to check continuity through the switch and safety thermostat when the unit is cool and switched on. Replace any component that is open when it should be closed.
