Replaced the old one with the new one, the only problem the new grill vent came without the clips and new screws. Other than that the grill is perfect.

One Phillip's screw to remove glass on bottom of unit. Pull old bulb out & insert new bulb. Replace glass & screw.

The halogen light bulb is very tight in the socket and difficult to remove by hand. Read reviews by other customers who had the same issue and complained that they ended up breaking the bulb trying to remove it. If broken may require an on-site service technician to remove the whole assembly with additional much higher cost and time. I found wrapping some duct tape around the burned-out bulb made it easier to grip and remove the old bulb without breaking it.
Based on some You-Tube videos I watched newer models now use LED light panels which appear to solve this problem.

I first unplugged the microwave. I then unscrewed the 2 screws from the top grill. I had to be careful because the grill was cracked close to each screw. It was a little tricky to remove the grill. Had to tilt it down as I removed it, and make sure the microwave door was opened as wide as possible. Filters were placed as the old ones, with the metal part up I believe. A little tricky to get one of the filters to fit. Grill was replaced with care so as not to further Crack it. Kind of maneuvered grill back in place, getting right side in place first. I noticed there were several tabs on the grill that needed to be placed inside of the microwave body while reinstalling the grill. Once the grill was in place, the 2 screws were put in to hold the grill in place.

Remove “over the stove” unit. Remove unit shell case. Unscrew and disconnect diode. Replace diode. Re-assemble. Put unit back in place.

Really easy for a 75-year old female; just spent more time reading the online manual than actually installing the light bulbs to find out where to access the light bulbs.

Don't waste your time with other parts stores online. Partselect sells quality parts and they arrived 2 days early. I purchase a door switch from another online store and the switch was defective.

This should be a 1 minute repair. However, there are a few issues. First, make sure you order the correct bulb. Mine is a halogen push in bulb, but the parts list showed a screw in bulb.
Remove power from the unit OR be sure that the light is turned off with the push switch.. The display will show the status as you rotate through the dim levels.
There is a single Phillips head screw holding the cover on the underside of the over stove microwave. carefully remove it. When loose the panel will drop down and you will find the old bulb in the center of the front of the opening. Remove the bulb. Now the important part. Carefully unpack the new bulb being careful to not touch the glass with your bare hands or fingers. Then insert the bulb into the socket.
If you unplugged the unit then plug it back in and push the switch to check that the new bulb works and is in the socket, then turn it back off.
Carefully lift the cover back into position and replace the screw. This is the hard part as you are working upside down and can't really see when it is lined up properly. When you have the screw back in and tight you are done. Press the light switch to enjoy your lit up stove again and put your tools away.
If you get your fingers on the glass bulb then clean it off with some rubbing alcohol and a paper towel to remove any finger oils before you put the cover back in place. Finger oils can boil with the heat of the lit bulb and cause the glass to explode. This holds true for any halogen bulb.

Turn off power supply at breaker . Replace old bulb with new bulb .

I ordered a new one then put the new one in the microwave. Easiest fix ever!
