Ice maker indicates defrost or de-ice error, heavy frost or ice buildup around evaporator

Safety first: Disconnect power before defrosting or accessing heaters. Water may drip; protect flooring.

• Manual defrost: Remove the ice bin and front panel. Allow the unit to sit unplugged with doors open until all ice and frost melt. Use towels to absorb water.
• Inspect defrost components: Locate the defrost heater and thermostat near the evaporator (if your Maytag model uses active defrost). Check for broken wires or burnt spots.
• Test heater: Disconnect the heater and measure resistance. An open circuit indicates a failed heater that must be replaced.
• Test thermostat: With the thermostat cold, check for continuity. Replace if open when it should be closed.
• Check control board: If heater and thermostat test good, the defrost control circuit on the main board may be faulty and require replacement.
• Restore airflow: Ensure fans and ducts are clear to prevent reoccurring frost buildup.
