Ice maker runs but does not produce ice, bin remains empty

Safety first: Disconnect power before accessing internal components. Sharp metal edges are present; wear cut-resistant gloves.

• Verify water supply: Confirm the water supply valve is open and the inlet line is not kinked. This rules out simple water issues.
• Access evaporator area: Remove the front panel and ice bin. Remove screws securing the evaporator cover to expose the evaporator plate and thermistor.
• Locate thermistor: On many Maytag ice makers, the evaporator thermistor is clipped to the evaporator plate or embedded in a bracket near the plate.
• Check connections: Follow the thermistor wires back to the harness and ensure the connector is fully seated on the control board.
• Test thermistor resistance: With the unit at room temperature, disconnect the thermistor and measure resistance with a multimeter. Compare to the Maytag service chart (commonly 8–12 kΩ at 77°F). If reading is open, shorted, or far off spec, replace the thermistor.
• Inspect control board: If the thermistor tests good but the control does not initiate freeze cycles, the temperature sensing circuit on the main control board may be defective and require replacement.
