Question about KitchenAid KCMS145J Microwave Oven

1 Answer

I have the same latch problem that you really thoroughly described the problem and resources back in 2006.  It was in KCMS145J 1100 Watts Microwave Oven >Troubleshooting My problem is that I have removed the part you refer to as #7 the Release Latch it doesn't seem to be broken but still doesn't logically and securely go into place to do the job. Am I missing something? A small part that would better secure that part in place. I am pretty good about figuring things out but this real tricky. Thanks in advance for your response.

    Thanks for the response. Your links helped alot.


    What I found had happened is that the grey plastic part that held the left "axle" of the white latch (#7) had snapped off the wall.  It was such a clean break I did not see it as missing.


    I found it later wedged a good distance away and that's why I didn't suspect a broken part but knew one was missing.


    Superglued back and latch works. Good to go.


    Thanks again.

    I have the same problem that I fixed today also using super-glue. After studying the problem a little more, I concluded that this high-impact grey molding that contains this little grey latch extension piece was poorly designed.

    There is a little grey latch piece that is a part of the one-piece high impact plastic control panel (Part # AP3859379 for Stainless) that holds the white lever release in place. The white lever release is attached to 2 latch exensions on both sides of the lever via an axel.

    When you close your door, a hook on the door applies a very strong force on the white lever release, which transfers this energy to the axel, which puts a force on this little latch extension on the plastic control panel. Over time, it puts great strain on this piece and it WILL break. The grey latch for the axel is very thin and flimsy and its a breakage that is just waiting to happen. We've had our microwave for about 5 - 6 years, so I'm actually surprised it lasted that long.

    Here's some additional information for owners of the KCMS145J KitchenAid microwave. There will be other people reporting this problem in the future as this part of the door latching/opening mechanism is pretty flimsy construction.

    1) The first frustrating thing was getting the top lid off the microwave unit due to the use of special security screws that I believe were intentionally put on there to discourage average users from messing with the unit. At first glance they look like allen-wrench type screws but on closer examination, the screws have a little pin in the center of the hole that requires a special tool. Home Depot and Lowe's did not carry this tool. I had to go to Harbor Freight to buy it. Its a cheap tool, but hard to find. You will need a Torx Wrench (T20 x 100mm) in order to unscrew the 4 or 5 screws that hold the top lid of the microwave on the unit. Its also easily available on the Internet.

    2) Be careful not to touch the Magnetron or the other parts of the microwave once you have the hood off. In order to pull the control board aff the unit, you unscrew one screw on the top of the control board and carefully unplug the 3 electrical connectors that are hooked into the circuit board. After that, the control board comes right out.

    You can either 1) super-glue the broken off extension piece that holds the white lever release axel in place (and hope for the best) or 2) order a completely control board. On 1/1/2009, athttp://www.appliancepartspros.com/partse... the price for this part was around $60 for the stainless steel model. Unfortunately, the piece is a one-piece unit that also contains the veneer for the external side and for the stainless steel model that we have, its pretty pricey. They don't sell the cheap grey high-iimpact plastic mount part (which is what I really need) separate from the veneer, so a $5 part is now $60 - grrrrrrrr.

    I would not suggest modifying the unit if that's what you mean when you mention a "small part that would better secure that part in place".

    If you could provide a link to the specific problem & solution you're referring to it would be more helpful than a link to a section page as above.

    You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

    Latch parts can be worn - such as the prongs on the door open button or the face of the latch lever - and this can lead to their failure to open the door.

    Once we have a better idea of your exact problem, we'll probably be able to help better.

I wouldn't trust the super glue, especially if it's a nylon part.

I would use epoxy, but you may not have enough room to slather it on without getting it in the pivot hole, etc.

A new latch (release lever) may very well be needed.

Good luck.

Emerson microwave door latch


I have an Emerson MW8999RD that all of a sudden yesterday wouldn't latch. I don't think you have to, but I took the door off (three screws hold the case on which needs to be removed to get at the top hinge). Then I took off the inner plastic picture frame - pretty easy with a thin blade to move the fragile tabs. Then I removed the metal frame that has the little microwave blocking holes. This was the hardest part because the plastic retaining tabs are even more fragile and I broke one. Then I found the loose spring due to broken plastic hook as described above. I was able to make a new hook by simply looping a small zip tie where the old plastic hook tip broke off. Now works great!

Can I still use the microwave if paint is peeling in one corner?


Yes, but it really should be fixed to prevent rust and arcing.
The area will first have to be sanded smooth and cleaned and dried thoroughly.

If the cavity metal of the oven is cracked or split, you can use a small amount of steel-based epoxy such as JB-WELD to patch the crack or hole.
Once that dries thoroughly, you can sand it very smooth.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

Door error message on microwave whirlpool Gold rmc275pd


This indicates the door is not latching. The simplest fix is if it really isn't closed, and simply pressing on the door does the trick. Not so lucky? Latch mechanism itself may be dirty and not latching. Try cleaning it with standard spray kitchen cleaners and a good scrub, followed by a toweldry. Still no good? There's often an electronic interlock-- a place outside the latch, perhaps along the face of door, which must contact the body of the microwave oven. Again, try cleaning all possible contact areas. No? OK: microwaves are designed not to run without a tight seal to prevent emissions. perhaps the seal itself is damaged. Finally, and most unhappily, and expensively, the electronics module in the combo unit is shot. If the appliance is under warranty you're in like flynn; if it's relatively new but not under warranty, call the Whirlpool service 800 number and very politely but firmly remind them that this is really quite a new unit and certainly their products aren't meant to fail so soon... and surely they have a service bulletin because this can't have just happened to you... This will usually result in (oh happy day!) a free service call or (more common) a deal to sell the part at half price. Better than nothing!

Door-activated power switch is loose and/or has a short


Fixed this problem! The door latches were greasy and sticking in the closed position (i.e., pushed down so not latching and engaging fully when the door was closed) and this created the problems described above. Solution was to squirt some Windex into the latch holes to dissolve the grease. The switches popped back into position (must be spring-loaded) and the door closed and latched properly, allowing the oven to function properly. I swabbed out the hole with a q-tip, let it dry for 20 minutes and all is well.

The door will not latch


The latch head (with hooklike projections) have a spring to keep it pulled down. If the latch head can be easily pushed up and falls back freely, then the monting tab on the back of the latch head is broken and it will have to be glued or replaced. The new part is better. To get to the door screws inside, you have to remove the choke cover, as shown in the photo. You can order parts for Sharp models from Tritronics at http://www.wehaveparts.com.
