Symptoms You May Notice

Foods cook unevenly with hot spots because air is not circulating.

No fan sound during convection cooking

The convection fan should produce an audible whirring — silence indicates the fan is not running.

Convection cycle cancels with error

The microwave stops convection mode and shows F7 shortly after starting.

Possible Causes

1

Failed convection fan motor

The fan motor has burned out or its bearings have seized.

Requires Professional
2

Fan blade obstruction

Debris or a loose turntable component has jammed the fan.

DIY Possible

Safe Checks You Can Do

These checks are safe for homeowners. No disassembly required. Do not remove panels or access internal components.
  1. 1

    Check for loose items

    Remove the turntable and check for any debris that might have fallen into the fan area.

    A small utensil or piece of foil can block the convection fan.

  2. 2

    Test basic microwave mode

    Try standard microwave heating — it should work since it does not use the convection fan.

    Basic microwave functions are independent of the convection system.

When to Call a Professional

Contact a qualified technician if:

  • Fan motor has no continuity
  • Motor shaft does not turn freely
  • Fan blade is cracked or loose
