Russell Hobbs Keep-warm temperature control failure

Keep Warm function does not maintain temperature; food becomes cold or continues to cook vigorously.

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

Incorrect temperature calibration on control PCB, Faulty NTC sensor, Stuck relay or triac, Poor thermal contact between sensor and plate

Safety: Unplug before internal checks.

Steps:

Observe behaviour: After cooking, monitor the Keep Warm mode. If it boils vigorously, the unit is overheating; if it cools completely, it is underheating.
Check sensor seating: Ensure the NTC sensor is firmly against the heating plate.
Test with water: Fill the pot with water and run Keep Warm. Measure water temperature after 30–60 minutes. It should be hot but not boiling.

Repair: Replace the NTC temperature sensor first. If the problem remains, the control PCB likely needs replacement.
