Proline Temperature Sensor or Thermostat Error

Microwave shows F2 and may run the fan unexpectedly or refuse to start a cook cycle.

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

Open cavity thermostat, Shorted temperature sensor, Loose sensor wiring, Faulty control board temperature circuit

Safety first: Unplug the microwave and let it cool.

User-level checks:

Ensure the unit is not installed in a confined space without ventilation.
Clean vents and remove any obstructions.
After cooling, plug in and test again. If F2 reappears, internal sensors need testing.

Next steps:

A technician should test the cavity thermostat and temperature sensor for continuity and correct resistance, replacing as needed.
