Gerald S Mechanicsburg , PA February 10, 2020 The microwave needed the charcoal filter changed and the interior light bulb replaced. Unscrewed the cover, slid back the light cover, unscrewed the old bulb and screwed in the new bulb. For the charcoal filter, slid it back a little until could pull it up and out and slid the new one in place. Very easy. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
