Put s pot under were you take the screw out.If you drop it you can get it easy

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

Removed the microwave from above the oven by loosening the two screws above the microwave. As the unit tilted outward lifted up and the whole unit came out all the time feeding the power cord through the cutout for the power cord. After it was out removed the cover and identified the capacitor and made sure it was discharged and removed and replaced the diode. tested before reinstalling and it heated up just fine. Reversed order and reinstalled . Very easy job maybe a second hand to help fish the power cord when installing and removing.

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.

The replacement part was identical to that of the original microwave and arrived in perfect condition.

The repair was extremely simple - too screws and a "snap" and it was done.

Couldn't be happier with the results. Thanks, Part Select!

Unplug the microwave. Removed the glass tray, the roller ring, and plastic piece that sits on the motor shaft from the inside of the microwave. Remove the 12 Phillips head screws from the bottom of microwave, let the bottom hang down on the mounting hooks at the rear of the microwave. Remove the 2 torx screws from the mounting bracket under the microwave lower the turntable motor remove the two leads. Transfer the rubber washer from the old motor to the new and reassemble and test. It took longer to write these instructions than it did to do the job.

Hint: if the microwave is over a stove lay a towel across the stove to catch any screws that may fall.

Good luck and enjoy your fully functional microwave!

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 .

We needed a phillips head screw driver to remove the single screw holding the light bulb cover in place.
Removing the old bulbs was a little work, because they had come loose from the sockets. We unplugged the microwave, so we could grip the sockets with a tool. I think my husband used a needle nose plier for this.
The new bulbs screwed in easily, and then we refastened the light bulb cover with the phillips head screw driver.
