Ice maker will not turn on at all (no lights, no display, no sounds).

Safety: If you are not comfortable working with electricity, contact a qualified technician.

Steps:

• Check the household circuit breaker or fuse for the ice maker’s circuit. Reset or replace if tripped, and investigate why it tripped if it happens again.
• Verify the outlet has power by plugging in a known working device or testing with a multimeter.
• Inspect the Marvel ice maker’s power cord for cuts, burns, or loose connections at the rear of the unit.
• Unplug the unit, remove the control access panel, and look for an internal fuse on the control board. Test and replace with the same type and rating if blown.
• If power is present at the board but there are no signs of life (no display, no relay clicks), the main control board is likely failed and should be replaced.
