8. Troubleshooting
If your heater is not operating correctly, consult the following common issues before contacting support:
- Heater not turning on: Check the main circuit breaker to ensure power is supplied. Verify that the heater is securely mounted to the wall, as it contains a safety switch that prevents operation if not properly installed.
