Amana Erratic Temperature Control

Freezer interior temperature fluctuates widely; sometimes too warm, sometimes too cold.

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

Failing thermostat (mechanical), Intermittent thermistor connection, Loose control board connectors, Poor airflow due to blocked vents

Safety: Unplug the freezer before accessing controls or wiring.

Steps:

Check loading: Ensure vents are not blocked by food and that air can circulate freely.
Mechanical thermostat: If tapping the thermostat knob causes the compressor to start/stop erratically, replace the thermostat.
Electronic models: Inspect and reseat thermistor and control board connectors. Replace a thermistor that tests intermittently open/short.
Control board: If wiring and sensors are good but temperature swings persist, replace the main control board.
