Drawer tries to close and then opens

It is a motorized drawer and I doubt it likes being opened manually. It would need to be repaired professionally due to the inherent dangers of microwave energy. The drawer motor would be operated by a relay.

Did you read any reviews before you purchased it?

Thumbs Down

- Looks great but features are bad.

Drawer microwaves and this model in particular look great. We did a big reno in December and this is now in the island. Looks good and functions as a basic microwave. Everything else is just south of mediocre. I'd suggest you get a drawer microwave from another company. Bad Stuff: - door opens/closes very slowly (~4 seconds)... doing a 30 second reheat now takes 4+4+30+4+4 = 50% longer just standing around. Likely similar with other drawers, but an unexpected negative. - doesn't let you tell it to start until fully closed - its default sounds and reminders are ridiculously annoying - beep-beep-beep on finish, and 10 seconds after that, and 10 seconds after that, and.... on and on - it forgets all settings during a power outage, turning back on the annoying sounds - and forgets your network connection - but good news, you won't want to use that feature - controls are not intuitive - classic 40 buttons where you use 5 The WiFi & App - hilariously bad. Design in your head the things you would want in a microwave app. Sharp engineers designed the opposite. Can you set the alarm settings in the app? No. Do you get a notification each time the microwave finishes cooking? Yes. I guarantee you will delete the app within 48 hours. Hand Wave to open. Neat right? No. Take how long it takes for this thing to open/close and add another 4-8 seconds of waving your hands (which are full food, else you'd just press the button) to then wait for the drawer to open. Push to close works well, but it reacts in a weird way, so some concern I'm breaking it. I stopped doing wave to open after the first week and stopped trying to demonstrate it to friends after one month (cause it will make you look silly). Height - just tall enough - fits a Venti coffee Cooks at 950 watts - basically the same power as a college-dorm microwave Cost. my god, how much did I spend on this. The good: Looks good Flush install if you have a good installer; mine is shown in a 30" wide lower microwave cabinet by Medallion Reheat sensor cook works well push to close works. It was suggested that I buy a Sharp because they have the patent on the drawer microwave and everyone else is just a re-labelled Sharp. I would suggest you give the others a look. They may be using the same hardware, but hopefully they have a more customer-focused interface and better software engineers working for them.

Lots of issues with this gimmicky microwave. Call for service, the only thing you can try is a power reset. Reviews are not good which is odd for a brand leader like Sharp.

Sounds like a door latch needs an adjustment that only a qualified technician can perform for safety reasons.

My drawer has been sticking for years and always required a little force to get it to open.
Just fixed it by putting a little silicone grease on the drawer hooks that are exposed when the drawer is open

I've got the same model and the same problem. Inside the microwave the Noise Isolation transformer shows black carbon from arcing on both sides of the PCB, but only no one pin.
It looks like a short to me, but I'm not sure what to replace. It appears this might be a common problem.

Where do I purchase a waveguide for this particular microwave

The drawer often stops working when it is abruptly stopped while opening and forced closed or vice-versa. To fix, simply do the following:
1) Push the draw all the way closed
2) Push the "Setup" button repeatedly until the "Open/Close ...?" appears.
3) Hold the Start Button until the time reappears in the display.
4) Repeat steps 2 & 3 three more times
5) Unplug the Microwave for 30 minutes.
The drawer is now reset. The drawer will now open electronically (automatically) either by pushing the open button on the panel or by pulling the drawer handle slightly.

It will have a one year warranty.

I would contact Sharp for their nearest authorized servicer.

I found this on another blog and it worked for me.


Model #KB6024MK, this is a Sharp microwave drawer that would open and close properly, but when started would not heat. These drawer units will sometimes close properly, but not enough to actuate the interlock switches to power the magnetron. A quick test is to turn the unit on and press in on the drawer handle while it is running. If you start hearing the low hum of the magnetron, the interlock assembly is out of adjustment. Removed the left side panel and gained access to the switch mounts to do a quick adjustment so when the drawer closes, the switches close properly to allow operation. It may take more than one adjustment to make it work properly so test it several times before reinstalling the side panel. It should work properly when the drawer auto closes and should not require any manual manipulation from the user.
