How to Fix / Troubleshooting
Safety: Turn off power before testing switches.
- Inspect door and curtain: Confirm the door closes properly and the curtain is not broken or missing its magnet (if magnetically sensed).
- Check switch alignment: Ensure the door or curtain properly actuates the switch or sensor when closed. Adjust mounting screws or brackets as needed.
- Test door switch: With a multimeter, verify continuity changes when the door is opened and closed. Replace the switch if it fails.
- Check wiring: Inspect the harness from the door switch to the control board for damage or loose connectors. Reseat connectors.
- Control board: If the switch and wiring are good, the control board may be defective and require replacement.
