Princess Convection Heater or Fan Failure

Microwave convection or hot-air function does not heat, but microwave-only mode works.

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 convection heater element, Failed convection fan motor, Faulty convection relay on PCB, Broken temperature sensor for convection mode

Safety: Unplug and let the unit cool before testing.

Preheat test: Set convection mode to a moderate temperature and wait. If the cavity does not warm and no fan noise is heard, the convection system is faulty.
Check for error codes: Some Princess models may show an error related to convection; note any codes for the technician.
Service: A technician should test the convection heater, fan, and sensor and replace faulty parts.
