KHMS2040BSS0 KitchenAid Microwave - Instructions

Part of the support was missing. I had to remove the two switches and put them in the new bracket
Had the switches reversed and started blowing fuses. Reversed them and changed the fuse and it started working.

easy to replace, just the same as cleaning the turntable and placing back in the micorwave;

screwed in new bulb

Unplug appliance. Remove total of 7 phillips screws from sides and front of bottom panel . Panel front drops down, remove one socket screw and socket. Now have access for lineman' s pliers to unscrew bulb base. Reinstall socket, replace bulb and 7 panel screws. Restore power.

Washed the glass tray and put in the microwave oven. Easy..

Husband replaced the 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.

Cleaned the interior of my microwave, cleaned the new plate and simply added to the turn area.

Removed turntable
Place support ring in track
Place turntable on support ring.
Easy, peasy!

PartSelect website indicated replacing the high voltage power supply diode is the solution for "no heat" 99% of the time, but the diode was OK. There is more info at the website concerning the case of "loud buzzing and no heat" indicating the magnetron needs to be replaced. As an electrical engineer with knowledge of microwave components, this was also my best guess. However, getting to the magnetron is not the easiest job, but it's not impossible. You also have to be careful to bleed off any charge stored on the high voltage power supply capacitor. Luckily, I found my KitchenAid service manual tucked away inside the unit since I couldn't find it online.

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

Rep knew exactly what I needed when I described where the part should go on my microwave - price great - shipping great - installed in seconds. Thank you!

I ordered another one and placed it inside the microwave. It works and fits perfectly. I received the order exactly as scheduled.

Spouse just screwed in the new bulb and reinstalled the light cover plate with the two screws. Took under a minute. Works great.

Looked up the Whirlpool Co. and ordered the part. It was quite simple. Arrived in 2 days and I simply placed it in the microware. It was very very easy!
