how to start homemaker microwave model EM720CPI

It was held in place by the same kind of plastic plugs I’ve seen used in actual packaging, so I was now feeling pretty sure this thing was probably more packaging. It seemed weird, so I double checked to see if the ‘manual’ (a folded up piece of paper) mentioned this thing. This kitchen isn’t terribly well lit, but still. There was lots of packaging, even inside the door, and the last thing I removed was this weird piece of ‘cardboard’ inside the microwave. I bought a microwave today, and I really need it in my empty new house. Setting aside other concerns, what the hell were they thinking not mentioning that ‘this is not packaging’ in manuals at -least. So I started Googling and a comment here finally made clear that this is the (dubious) ‘upgrade’. So this mica that looks exactly like more cardboard, held in place with melty looking plastic plugs that actually are used in packaging, is the ‘upgrade’ from built in plastic covers? Once I understood it wasn’t packaging I thought my new microwave must be cutting corners, using some cheap old timey thing I had somehow never come across. The cover can be replaced either with a suitable replacement made by the manufacturer of the microwave or if the old cover is in good enough shape to be used as a template, blank sheets of mica can be purchased and cut to fit. Over a period of time it absorbs moisture and gets food splatters on it. When new the mica sheet is rigid and firm. What should I do ?If there are any issues with your waveguide cover it should be replaced. If it is arcing or sparking then continued use will damage other components in the microwave including the oven cavity which could be costly to rectify. If it has fallen off or got a hole in it then there is the risk of food or moisture getting into the waveguide which will reduce the efficiency of the oven.

In any eventuality it should be replaced. If your microwave is working ok and behaving itself then there is nothing to worry about, but there may be one of 3 problems that may arise which should be rectified.
