KMHP519ESS4 Whirlpool Microwave - Instructions

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.

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!

Removed panel and installed upper and lower switches. I did this because it did not do it all the time. When I removed the switches I used a ohms meter to check continuity but they all checked out at first then I started playing around with the buttons on each switch by pushing in on them and letting off and found one when you pushed in and out three or four times that one switch would jump back and forth by ohms meter that was the bad switch. If any one else has that problem the switch might show continuity when you first test but click the switch button a few times to see if you get a different reading. Microwave up running. Thanks Partselect.

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.

Used a philips head screwdriver to remove one screw holding the light cover. Pulled out the old bulb and inserted the new one. Replaced the cover.

Unscrew lens and direct access to surface light cavity. Removed old light bulbs and replaced with new bulbs. Reassembled lens cover and turned lights on successfully. Took less than ten minutes.

Just opened the door and dropped in new part and viola!

Repair unsuccessful because they sent the wrong part, even after I questioned their selection. It is amazing how a company as large as Whirlpool cannot clearly indicate to the people who work for them how to order the correct part. The fault lies not in the individual who is putting the order in but with the company who cannot take the time to make sure that person is successful in completing their job. Will never buy a product from this company again.
As far as the shipping is concerned. It took forever, just to find out that the part was incorrect.
Better luck next time. right?

On top front of the microwave are two Philip's head screws holding the rail on. Remove these screws and the rail snap out the old filter (noting the dark side down) then snapping the new filter in. Replace rail. 10 to 15 minute task.
