Indesit 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

Intermittent NTC sensor, Loose sensor connection, Failing thermostat knob or encoder, Control board logic fault

Safety first: Unplug before accessing controls or sensors.

Steps:

Verify the temperature setting knob or buttons operate smoothly and are not physically damaged.
Inspect and reseat connectors for cabinet and evaporator sensors at both ends.
Replace any sensor that shows intermittent resistance when gently flexed.
If fluctuations persist with new sensors, the main control board may need replacement.
