Caple Stuck Energy Regulator / Thermostat Failure

Electric ceramic hob zone overheats and does not cycle off, causing very high temperatures.

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

Faulty energy regulator, Failed temperature limiter on element, Shorted control contacts

Safety first: Turn off the hob immediately and isolate from the mains. Do not use the affected zone until repaired.

Technician steps:

Access the energy regulator for the affected zone and test for correct switching behaviour with a multimeter.
Inspect the temperature limiter on the radiant element for continuity; if stuck closed, replace the element assembly.
Replace any regulator that shows welded contacts or continuous output regardless of knob position.
