KHMS155LSS4 KitchenAid Microwave - Instructions

Slide grease filter about 1/2 inch to right (or left) using the d-ring attached to one side and then pull down and out. Push charcoal filter frame slightly to rear and pry down from front. Install new charcoal and grease filters by reversing process. No tools - 5-minutes max!!

First -- and this was the key to success -- I watched a couple of Youtube videos on "Replacing a microwave door handle". As one video suggested, I placed a large towel underneath where I was working (over the stovetop) to catch any falling parts but this proved unnecessary. Once I removed the two screws from the end of the door, the inside of the door pried off easily with a screwdriver. It did want to drop quickly though, so be ready to hang onto it. The handle was attached with two screws (which I reused, no problem). It took a few minutes to re-insert the inside of the door into the frame, but once that's done, you just re-install the two end screws and you're finished.

No repair- just replaced glass turntable.
Right part I needed with first try

Since the handle came with no instructions, . The part came very quickly and the site was easy to use.

Don't order the two screws. They are common screws you probably have in your garage.

After unhinging the microwave door, be carefeul taking the door apart. Do it over a kitchen counter covered by a towel padding. It came apart suddenly and half of it fell on the floor, but didn't break.

Removed old grease screens by sliding sideways and then pulling out of the grooves. (helps to have rubber gloves as the grease is slippery). Put pressure on the back of the charcoal filter rim and allow side closest to you to drop down slightly so you can get a fine flatblade screwdriver under and pop the filter out of the holder. Works same on both sides. Install new charcoal filters after cleaning the holder edges with soap and water and drying. Make sure charcoal filter is in the second set of holder grooves and snap in place. Replace new grease filters with the pull tabs down and facing the center. Slide the grease filter into the holder grooves a little further back than normal and (using the pull tabs) pull the filter back the other way until flush with the opening and in place. The top exit ports are removed by taking out 4 screws;however, two of them are attached to spring clips on the underside and it is easy to break off the tiny plastic ridges underneath. The other screws come out easily and the entire exit port piece can be removed and cleaned. To reinstall just snap exit port back in place and replace screws. If you have broken off the slender plastic ridges you can sometimes turn the screww a partial turn and engage what is left; if not you may have to put some rubber grommets or pieces to support the bottom and keep pressure on the exit port piece which is not locked by only two screws.

this problem started two months ago when my micro quit heating up, after all the research most agreed it was the magnetron. taking the micowave apart is not to difficult just make sure you bag all the screws accordingly. the high voltage area is on the right hand side behind a panel. caution there is a capacitor that will bite if your not careful, need to short the circuit between the two connectors with an insulated screw driver it will make a small pop or let it sit for awhile and it will discharge by itself. The magnetron worked for two days then quit, after more research i took it apart again and tightened up all the connections. Worked great on the bench but when i got it back up on the cabinet two dayslater kaput again. so again i take it down and replaced the two cheapest parts in the high voltage system, magnetron thermst fix, and h.v diode. benched tested it this time for 3 days cooking anything that i could think of, worked great. its been one week now afer installtion and it is still working.

My microwave began suddenly making a loud harsh humming noise while cooking food. I did not let it go on long enough to know if it cooked the food or not. I did some Internet research and learned that it was likely the Magnetron. The test for this was to run the microwave for at least a minute on the lowest power setting and see if the noise cycled on and off. It did, so I (actually, my wife) ordered the part from partselect.com using the model number. I was successful in replacing the part, and we are back to microwave popcorn and quick defrost for a price that was less than a service call, however, it was time consuming, required a large work area, and access to 5 out of 6 sides of the unit. So proceed at your own discretion

Caution:

The first thing in every set of repair instructions was to discharge (short-circuit) the capacitor, as it may store large (as in lethal) amounts of electricity even when it is not connected to a power source. I had never done this, but found these instructions:

“Discharging your microwave's capacitor is absolutely essential in preventing injury to your microwave, your tools, and yourself. A capacitor stores a large amount of electricity even when your microwave is unplugged, and it must be discharged before beginning any repair.
A capacitor is discharged by creating a short circuit between each of the two capacitor terminals, and between each terminal and the chassis. The chassis is the metal mounting (bare metal surface) of the capacitor. Read these directions thoroughly before you proceed.
With your microwave unit unplugged, touch the blade of a well insulated screwdriver to one terminal. Gently slide the screwdriver forward until it reaches the other terminal, holding it there for a few seconds. Be aware that this often results in a loud and startling 'POP'.
Repeat this procedure in order to create a short circuit between each capacitor terminal and the chassis (bare metal mounting plate surface). This same method can be applied to a capacitor having three, and not two, terminals.”
I had not run my microwave in over a week, and then while my part was shipping, left my microwave 'unplugged' for more than two days, and my capacitor apparently discharged itself, although I did go through the above procedure carefully and completely - just in case.
Step-By-Step:
1. You must remove your microwave from the cabinets - it is impossible to repair otherwise. This is best accomplished with 2 strong people - my wife and I made it work, but wished for another guy.
a. While supporting the microwave, remove the two screws coming down through the cabinet above.
b. Lift the rear of the microwave as much as possible, then tilt the front down - there is a clip high on the left side, as well as the hinge/clips on the bottom.
c. If you do not lift it off the wall all at once, you may have to lift the rear even farther to remove it from the hinge/clips on the bottom.
Important Note: Always beware of the microwave door, if it is bent or broken and cannot retain a seal, the microwave not function as a safety feature to keep from releasing microwaves.
2. Remove the vent cover on the top/front of the microwave - be careful, it's plastic.
3. Remove the vent cover and light panel on the bottom of the microwave - this is several screws and some simple wire clips.
4. Remove the "shell" (top and sides) of the microwave - this is several more screws on the back. Make sure to remove the plate that is holding the cord in place on the top.
5. Remove the interface panel by the screws on the top (which had been hidden by the vent cover) - the wires can remain attached, just slide it aside.
6. Remove the metal cover on the right side at the rear; this will expose the Magnetron and the Capacitor. Remember to immediately test and discharge the capacitor!

7. After you discharge the capacitor, remove the other cover plate and the support bracket - in case you haven't noticed, this is a time and space consuming operation.

8. You

I dropped the grease filters ( two under the unit) and then removed the dirty charcoal filters. The new charcoal filters were then snapped into place and the washed grease filters were then put back. The entire job took about. 5 minutes. No tools needed.

PartSelect had the turntable I needed at the best price. Ordering was easy, but best of all, the part was delivered next day. I was able to insert the new turntable plate into the microwave and it was good as new.

Have you ever tried getting the inner seal off a microwave door in order to replace a door latch or the handle? It is not an easy job. I was advised by a service technician that they usually just order a complete new door for a broken latch or handle as it is so difficult to get the seal off without damaging the door. I priced a new door, and it would have been more than the microwave, so I searched the internet for ideas. I found several sites that gave various suggestions. What worked for me was to slide a putty knife inbetween the top of the inner seal and the door - starting at the top right corner and working along the top first. I actually used several knives so that the six clips that are along the top did not pop back into their sockets. The first clip is 55 mm from the top right corner. There is then more every 95mm along the top of the frame. If you can push these in with a knife, keeping the knives in place, you will be able to carefully pull the seal out. From the top left corner going down, there is a clip 25mm from the top, and another 85mm from that point - again push a knife in to release the clip. Carefully work your way along the bottom, The clips are in the same place as on the top. Then work along the edge closest to the microwave. With a bit of patience, the seal will come out in one piece. Even if you break it getting it out, it is better than the alternative, and you can always get another one at partselect.com
Once I had got the seal off, I thought I was home dry and the rest would be easy. Wrong! To get at the broken latch for the door (same if I was replacing the handle) I still had to get the stainless steel outer shell away from the main frame of the door (without bending it) and there was clips all along that had to somehow all be pushed out of their sockets at the same time so that the stainless steel outer shell would come away from the rest of the door, and I could get at the screw that held the latch in place that needed to be replaced. I came up with the idea of pushing 2 quarters in the gap between the door shell and the main frame next to every single clip. I then went back along where all of he quarters were pushed in, and pushed a penny inbetween the two quarters and this opened up the clips just enough to disengage them from their sockets, but without bending the stainless steel. As I gradually went around the door pushing the pennies in, the outer shell poped off, and I could get at the screw to get the broken latch off. Once I knew I could get at the part that I need to replace, I went on line and searched for a place to get Kitchenaid parts. That is when I found this site. I ordered the 2 parts that I needed from partselect.com at around 2.30 PM. At 3.15 PM the next day they were delivered to me in South Florida, and within 10 minutes they were out of the packing, and I had the microwave fixed. Getting to the part that needed replacing wasn't easy, but I hope that the above makes it easier for somebody else in a similar situation. The service from partselect.com was excellent. I had never heard of them before, but would certainly recommend them to anybody.
Regards

Opened the box and popped it in. No problem with that.

The part was sent to me the next day! And it was the right part. Awesome!

set the table on the support ring

Why a tenant would remove and discard the grease filters without replacing them is beyond me! But, I removed the filters from the package and slid them into place. Two minutes tops. I would like to add that I ordered these on Thursday afternoon, and I had them on Saturday; awesome customer service!
