Part F2055BP20APPanasonic Genuine Panasonic microwave oven waveguide cover. Panasonic service parts lists identify F2055BP20AP as "COVER" (reference 8); an authorized Panasonic parts agent identifies it as a waveguide cover measuring 85 mm x 120 mm. Is This the Right Part? Part NumberF2055BP20AP ManufacturerPanasonic Appliance TypeMicrowave Part TypeMicrowave waveguide cover Common Symptoms Visible burn marks, scorching, cracking, holes, or heavy food contamination on the cover Burning smell or smoke during microwave operation Uneven heating or food cooking irregularly when the cover is damaged or missing Sparking that continues after metal objects and food residue are removed Check Before Replacing Unplug the microwave and allow it to cool before inspection. Visually inspect the exact cover for burn marks, holes, cracks, warping, looseness, or heavy grease and food residue. Check that the cover remains present and is seated in its original position; do not operate the microwave with the cover missing. Clean the cover and surrounding cavity surfaces only as directed in the Panasonic operating instructions, using a soft cloth and suitable mild cleaning method; do not scrape, abrade, or remove the cover. If sparking occurs with an empty cavity or microwave-safe cookware, stop using the microwave and arrange qualified service rather than assuming the cover is the only failed component. Pro Tip Keep the waveguide cover and microwave cavity clean and dry; food residue and condensation can damage the cover and contribute to arcing.
