Microwave fan and light wont shut off

fan and light wont shut off after the heating timer ends. pull the door open and the fan shuts off but the light stays lit. close the door and the fan starts running with the light on…

Sometimes, if I put the panel in "locked" mode and take it out of the locked mode, it fixes the issue. Now even that is not working… please help… am I looking at buying a new unit? :frowning:

I think no need to buy a new one. you must check its setting or call some technician who checked it carefully.
