Hotpoint Poor Temperature Regulation

Cabinet temperature fluctuates widely, overshooting setpoint

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Loose or poorly positioned temperature sensor, Airflow obstructions, Control board hysteresis settings off, Sensor wiring intermittently open

Safety: Unplug before adjusting sensor placement.

Check sensor placement: Ensure the cabinet sensor is not touching the evaporator or directly in the airflow from the fan; it should sense average air temperature.
Improve airflow: Avoid packing bottles tightly against the rear wall or vents.
Inspect sensor wiring: Look for intermittent connections or damaged insulation that could cause erratic readings.
Replace sensor if unstable: Install a new Hotpoint NTC sensor if readings jump around when measured with a multimeter.
