Ice maker produces ice, but ice production is very slow.

Steps:

• Clean the condenser coil thoroughly with a soft brush and vacuum. Ensure the front grille or toe‑kick is not blocked.
• Verify that the room temperature is within Marvel’s specified operating range (typically 55–100°F). Extremely hot rooms will reduce ice output.
• Check water pressure to the unit and correct any restrictions or partially closed valves.
• Remove the ice bin and inspect the evaporator plate for mineral scale. Clean with a nickel‑safe ice machine cleaner following Marvel’s instructions, then rinse thoroughly.
• Confirm that the ice thickness sensor is properly positioned and not causing premature harvest. Adjust or replace if necessary.
