ProCook Lower Temperature Sensor Out of Range

F2 error appears during keep-warm or low-temperature cooking modes.

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

Drifting NTC sensor, Poor thermal contact between sensor and heating plate, Sensor partially detached, Faulty PCB input circuit

Safety first: Unplug and cool the unit before internal inspection.

Check for loose sensor: Access the underside of the heating plate and verify the NTC sensor is firmly clipped or screwed in place.
Improve contact: If the sensor has pulled away from the plate, resecure it. In some designs, a small amount of thermal paste is used to improve contact.
Test with water: Reassemble, add water, and run a warm mode. If F2 recurs, replace the NTC sensor.
