KHMS1850SSS2 KitchenAid Microwave - Instructions

Unscrewed light cover then inserted lights. When I called your company gave them the model Number they knew the exact part needed promptly mailed the replacement lights.

This is an over stove top mounted oven. Remove oven from mount and place on a work surface with padding to support the lamps and vent holes. Strip the case off and locate the noted other "most likely" parts. Watch out for the Capasitor. Read the test note available for each part; Diode, Thermister Fix, Capasitor and Magnitron. Do the test checks. My issue wasn't obvious because I think the Capasitor was discharged and needed to be hot to check the Magnitron. (I'm not an electrical engineer so...) At this point I did the foolish thing...I plugged the unit in and ran it. Watching from a distance I saw sparks fly from the top side of the Magnitron with the same result from my cup of water (cold-no sprks here.) I replaced the diode and tried again, same result. I ordered the Mag and the Thrmst-Fix. Thrmst-Fix was on BO when the Mag got here so I installed the part. Had to remove several pieces to afford room to work and still had to stretch and pry to get the old out and new in. Mag is held in place with Torx screws so check that before you start. No other tool works. Mag was the problem for this unit. Some problems encountered: Parts and pieces were quick in arriving as long as they were not Back Ordered. Be careful to follow a thread for your product to order parts. These review/instructions are mixed for simular appliances and sometimes lead off to other part lists and numbers. Prices differ from model to model, list to list and the part numbers change. Go back to your product and then trace for the correct parts. I noted a $40 price dif.between Magnitrons from simular part lists. When you receive the part check to match the part numbers, Manuf. no. are different from the Part Select No. but can be crossed. Otherwise using this site's instructions, checks, insulated tools, big rubber gloves and a face shield I managed to save a $600 machine from the junk pile. Parts as ordered were recieved and return of un-touched parts were accepted by Parts Select without unexpected hassle. Thanks for a positive experience.

Ordered the item on a Monday at 12pm and it arrived the next day. Amazing!

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.

I simply removed the mesh guards in the bottom of the microwave ad placed the new charcoal filters behind them and replaced them in the slots under the appliance.

Problem was easily diagnosed using the internet as a resource, problem was a bad stirrer motor. Hardest part of the repair was the removal of the microwave. Once off the wall, you remove the outer cover and a molded plastic casing directly underneath the outer cover at the top of hte microwave to expose the stirrer motor. Removed two screws and two wires and the old motor is out. Did exactly the opposite to install the new motor. The kit I recvd included among other things the motor, a new inside cover, plastic rivets and even silicone to seal the inside cover. I am sure I saved a couple hundred dollars by doing myself.

just replace need cooking tray

I called the repair/parts number to make sure I had correct parts and the young lady instructed me as to the size of the serving tray; within 48 hours we had the VERY carefully wrapped carton opened and back in the microwave, working perfectly. Thank you. We'll recommend you to our friends!

removed grill cover, removed bulb plate, unscrew bulb, screw new bulb in socket,put bulb cover back on and screw grill cover back on. no issues whatsoever.

All I had to do was lay the new tray in the microwave. Easy as pie. Also, the new tray arrived very quickly.

The problem I have with changing the bulb is my microwave is an overhead one and therefore I cannot tip it on its side to easily replace the bulb. I have to drop the lid down and carefully install the new bulb from underneath.

There are two screws that hold the unit on. Very simple to install. When you clean the vent grille don't push too hard on it or you will be replacing it again...

Twas really easy considering that all I had to do was place the plate back in the microwave. Easy Peasey

Tray arrived in a short period of time and was a perfect match.

I didn't do the repair -- my husband did, said it was easy, had no problems what so ever! The new bulbs give a lot more light to the cooking area.
