F20559Y00AP is the genuine Panasonic mica cover for the NN-SD691S and NN-GD682S, and for NN-ST models including the NN-ST641W and NN-ST64JW, the NN-ST651W and NN-ST655W, the NN-ST663W and NN-ST665B, and the NN-ST671S, NN-ST67JS and NN-ST683S.\u003c\/p\u003e\n\u003ch2\u003ePanasonic microwave sparking inside?\u003c\/h2\u003e\n\u003cp\u003eMicrowaves travel from the magnetron down a short channel called the waveguide and into the cooking cavity. The mica cover sits over the opening in the cavity wall, letting the energy through while keeping food splatter and steam out of the waveguide. Over time, grease and food soak into the cover and carbonise, and the burnt spot can arc, spark and crackle during cooking. Left alone, arcing can damage the waveguide and the magnetron, so stop using the microwave and fit a new cover once you see burning or sparks.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Panasonic part F20559Y00AP\u003c\/li\u003e\n\u003cli\u003eMica waveguide cover\u003c\/li\u003e\n\u003cli\u003eListed for NN-SD691S and NN-GD682S plus NN-ST series models\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable class=\"part-specs\"\u003e\u003ctbody\u003e\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eMica\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2\u003eChanging the mica cover\u003c\/h2\u003e\n\u003cp\u003eUnplug the microwave before starting. The cover is on the inside wall of the cavity and is normally held by clips or tabs, so it can be changed without opening the outer case. Never remove the outer case yourself, as microwaves store dangerous high voltage even when unplugged. Clean any grease or carbon from around the opening, fit the new cover the same way round and test with a cup of water.\u003c\/p\u003e\n\u003ch2\u003eQuestions about this part\u003c\/h2\u003e\n\u003ch3\u003eCan I cut a sheet of mica to fit instead?\u003c\/h3\u003e\u003cp\u003eMica sheet can be cut, but this genuine cover is already shaped with the right fixing points for these Panasonic models, so it fits without trimming and sits flush. A poorly fitted cover can leave gaps that let splatter into the waveguide.\u003c\/p\u003e","brand":"Panasonic","offers":[{"title":"Default Title","offer_id":44549019500622,"sku":"F20559Y00AP","price":14.78,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0768\/3489\/7998\/files\/f20559y00ap-genuine-panasonic-microwave-wave-guide-mica-cover.jpg?v=1792026085","url":"https:\/\/partsshop.com.au\/products\/f20559y00ap-genuine-panasonic-microwave-wave-guide-mica-cover","provider":"My Store","version":"1.0","type":"link"}
