Georg B Salford , PA February 12, 2016 Appliance: Model KHHC2090SSS-1 Stupid human trick not watching what buttons you push!! microwave instead of timer for 15 min ? 8sqr inches of burn through the plate!!! it stalled the motor which fried I went on the internet forums for a consensus. Your advice matched. I got the only real microwaveable (white) paint advertised. Did meticulous sanding and cleaning for the bonding of the paint. Make sure there is NO oily residue! I lined the entire interior with poster paper. I made an EXACT cutout of the INSIDE circle of the track for the rotating support (@10 in.). Since taping is impossible, I weighted the edges with 3/4 in. nuts to get a seal. Then did 4 MIST layers 2hrs. apart. EXHAUST the room with a box fan. Wear a mask. Spray at 90 degrees in short bursts as high as possible. The over spray will cling to everything. It has an epoxy in it. Covering surrounding surfaces is easier.Clean immediately! Oven top cleaner on glass. De-Solv-It for the rest. Let cure 24hrs. before using. This turned out great even though my interior was gun metal grey. Installed the new motor (bottom filter panel/motor uses 10+15 torx bits) and parts. Total cost @ $100. The other choice? How much is a new micro/convection oven? $500 and up. I don't think so.
