Ice maker stops shortly after starting, displays E1, may not begin ice-making cycle.

Safety: Disconnect power before accessing internal components. Sharp metal edges may be present.

• Access evaporator area: Remove the ice bin and internal panels to expose the evaporator plate or grid in the ice-making compartment.
• Locate thermistor: The evaporator thermistor is usually a small sensor clipped to the evaporator plate or mounted nearby with two wires leading back to the control board.
• Check connection: Ensure the thermistor is firmly clipped in place and the connector at the sensor and at the control board is fully seated.
• Inspect wiring: Look for pinched, cut, or corroded wires between the thermistor and the control board. Repair or replace damaged wiring.
• Test thermistor (if you have a meter): With the unit unplugged, disconnect the thermistor and measure resistance. Compare to Hotpoint service specs for your model at room temperature. An open circuit or 0 ohms indicates a bad sensor.
• Replace thermistor: If faulty, order the correct Hotpoint evaporator thermistor kit. Install it in the same location and route the harness as original to avoid contact with moving parts or sharp edges.

Restore power and run a test cycle. If E1 persists, the main control board may also be defective and should be evaluated by a technician.
