Possible Causes
Low or high line voltage, failing internal power supply on control board, loose power connections, tripped internal fuse
How to Fix / Troubleshooting
Safety: Always disconnect power before opening any electrical compartment.
Steps:
- Verify that the outlet supplying the Marvel ice maker has correct voltage using a multimeter (typically 120 VAC in North America). Correct any household wiring issues.
- Ensure the unit is on a dedicated circuit and not sharing power with heavy loads that could cause voltage drops.
- Remove the control board cover and inspect for an internal fuse. Test the fuse for continuity and replace with the exact type and rating if blown.
- Check all line and neutral connections at the terminal block for tightness and signs of overheating.
- If voltage to the board is correct but the unit intermittently shuts down with E15, the board’s internal power supply may be failing. Replace the main control board.
