How to Fix / Troubleshooting
Safety: Turn OFF the breaker and verify no power is present before opening any electrical compartments.
- Inspect wiring: Remove the Alpha junction box cover and check for loose, burned, or shorted wires.
- Check elements: Disconnect each heating element and test for continuity to ground. Replace any element that is grounded.
- Dry moisture: If water has leaked into electrical areas, correct the leak and allow components to dry completely before re-energizing.
- Verify breaker size: Ensure the breaker and wiring gauge match the Alpha nameplate requirements.
If the breaker still trips after these checks, a professional electrician or technician should investigate further.
