How to Fix / Troubleshooting
Safety: Always turn off the circuit breaker before opening any electrical covers.
Steps:
- Check breaker and outlet: Verify the breaker is not tripped and that the outlet or junction box has correct voltage.
- Inspect power connection: Remove the toe-kick and open the terminal box. Check that the supply wires are firmly secured and not burned.
- Check door switch: A failed door switch can sometimes prevent power-up. Test continuity of the door switch when closed.
- Control module check: If power is present at the control but the display is dead, the control module may be defective and require replacement.
