steps
- stop the cycle
switch the microwave off. if there is smoke or fire, keep the door closed, do not reach inside and follow emergency guidance. seek emergency help if needed.
- look only when it is safe
once the microwave is unplugged and cool, check the removed container for foil or metallic trim and look for visible damage inside the cooking cavity. tell the repairer what you found. never remove the outer case, internal covers or door safety switches, even when unplugged.
