F9 error, unit may not defrost properly, ice builds up on evaporator plate or in chute.

Safety First: Unplug the unit and allow ice to melt before working near the evaporator. Use towels to catch water.

• Access evaporator area: Remove internal panels to expose the evaporator plate and any attached defrost or harvest heater (if your Amana model uses one).
• Inspect wiring: Check heater leads and thermostat wiring for burns or breaks. Reseat connectors.
• Test heater: Disconnect heater leads and measure resistance with a multimeter. An open circuit indicates a failed heater.
• Test thermostat: If a thermostat is in series, test continuity when it is cold (below its closing temperature). Replace if it remains open.
• Replace faulty components: Install new OEM heater and/or thermostat as needed, ensuring good contact and proper routing of wires.
• Clear ice buildup: Manually remove remaining ice and reassemble panels before restarting the unit.
