I had no problem installing the new filter. Just used a phillips screw driver to remove the two screws holding the vent cover in place. Cleaned the dust out of the ducts and reinstalled the new filter. The screws must be held to the screw driver with your finger tips so you don't drop them in the vent cover. The most difficulty I had was in clearing the clean code from the screen. There are no instructions in the owners manual for doing this. But after several tries I got it.
Took the replacement plate out of the box and put it in the microwave in seconds. I never realized how much of a difference having the correct microwave plate would make. It's great to have it back.
You had alerted that it was imperative to unplug unit before starting to remove defective bulb. As described, there was silicon on bulb and socket and bulb broke upon my attempt to remove. Had to use needle nose pliers to get metal base of old bulb from socket, then all went well.
My daugher used the vent grill on the microwave as a handhold while putting dishes away in the cupboard and broke it. I found the part via the Whirlpool website. When the part arrived I removed the two screws, placed the new vent grill in place and replaced the screws. Total time: About 10 minutes.
