Microwave with convection feature displays E8 when convection mode is selected; microwave-only mode may still work.

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

Failed convection fan motor, Open convection heater element, Faulty convection relay on control board, Loose wiring to convection assembly

Safety first: Unplug the microwave and allow it to cool before inspection.

User-level checks:

Listen for the convection fan when starting convection mode. If you hear humming but no airflow, the fan may be jammed or failed.
Check that the interior is not obstructed by oversized cookware that could block airflow.

If E8 continues:

The convection fan motor or heater element likely needs replacement.
These components are behind internal panels and require disassembly and electrical testing by a technician.
