I removed the two screws, removed the broken grill, popped in the new grill (after I ordered the correct color, did not get the biscuit color I thought I had ordered the first time) replaced the two screws....I was good to go. Strange that the tabs in the first place just fell apart...but reading others, find this seems to be a common problem. Simple as pie.
The old coupling melted and the tray cracked in half.
It took me 15 minutes total - 5 minutes to clean the microwave, 1 minute to install three new parts, and 9 minutes to enjoy my celebratory glass of wine!
Unplug the microwave. Then remove the six screws that hold the lower panel which has the light bulb cover and a couple of vent filters. The light bulb sockets are on a fixture that is connected by a quick connect electrical connector. Disconnect that and the whole panel is free to access the bulbs. My bulbs were very fragile and trying to twist them out resulted in the glass twisitng loose with the base still in the sockets. I needed to use a needle nose pliers to remove the bases and then I replaced the bulbs and put every thing back together
Took out the turntable parts to ensure I ordered the correct cooking tray. Matching those with photos of related parts on PartSelect worked great. Put turntable drive and support ring in place and cooking tray went in very easily. Plan to order a second one to have on hand for this rental property.
PartSelect was the only company to show that the part came in 3 different colors. The grill vent was used to replace a cracked vent. It was simmple to slip in the new vent,but be sure to save the existing screws that holds the vent in place
