Why does the reset filter light come on and won't go off?
i have no idea what the filter is or where it is.
"Open door- pull down tray above microwave cavity- check filter for particulate matter- shake off if possible/ replace if damaged/dirty.
Hold filter reset button for TEN SECONDS.
Red light will go off"
"Hi @ Pat Camfield
Here’s some images taken from the service manual for the microwave oven, that show how to clean and replace if necessary the filters and to reset the filter light.
