YKHMS1850SW0 KitchenAid Microwave - Instructions

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

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.

Attached bracket to wall with screws and hung microwave oven. Very easy project.

Remove the screws from the unit metal tabs. Insert two locator tabs of the grill into the slits in the unit and install the two mounting screws. SIMPLE

Arrived in 24hours!!! Great.

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...

Took out the screws and replaced the vent. (here is a trick, to make getting the screws in a rather hard to reach area I glued them to the end of the screwdriver-super glue)

Slide the old one out of the slot and insert the new one in its place.

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.

removed perimeter screws from the bottom side and the lower cover is hinged at the wall side. Motor is visible and easily removed with two screws. Take of the old one, install the new one, and reverse the procedure to put the bottom cover back in place. Will nee helper to hold one side of the bottom until couple of screws can be put in on the other side.

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.

Used the new parts, they were a perfect match, I completed the work in 5 mins or less. The pictures provided were very helpful, and parts were delivered very fast. Price was the lowest too!!

Removed the glass cover and replaced the bulb. Very simple.
