Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug and allow the unit to cool completely before opening.
Steps to troubleshoot no heat:
- 1. Confirm settings: Ensure a temperature above room temperature is selected and a timer is set. Some models will not heat without a time setting.
- 2. Listen for relay click: When starting a cycle, listen for a faint click from the heater relay. No click may indicate a control issue.
- 3. Inspect heating circuit: Remove the housing and locate the heating element assembly, thermal fuse, and wiring.
- 4. Test continuity: With a multimeter, test the heating element and thermal fuse. Replace any open components with Granitestone-compatible parts.
- 5. Check relay and PCB: If the element and fuse are good, the heater relay or control PCB may be faulty. Replace the main control PCB if the relay is burned or not energizing.
