Why a tenant would remove and discard the grease filters without replacing them is beyond me! But, I removed the filters from the package and slid them into place. Two minutes tops. I would like to add that I ordered these on Thursday afternoon, and I had them on Saturday; awesome customer service!
The repair was very easy, however the bulb was not the same as the original one. The original bulb had a bright setting and a low setting, but the replacement bulb was only the low setting bulb. There was no bright and dim operation. The switch on the microwave had the duel settings.
I bought the microwave on sale at Sears. the glass cooking tray was missing. It was to be ordered but after 2.5 months I had not received it so called Part Select and received the tray within 5 days! Ironically, the original one arrived the same day. I would recommend PartSelect for their prompt and very courteous service.
