Yes it is possible the door open lever got broken in shipping.

If your model has anti-tamper screws, you can remove them using using a T20H Torx type or GTXH20-100 screwdriver. If the correct tool is not available, there are several ways to remove the screws:

- Use a hammer and a small punch or similar tool to knock out the middle post of the screw, then use a standard T20 Torx bit to remove the screws. (Use safety glasses).

- Insert a small flat-bladed screwdriver (such as a jeweler’s type) into the slot between the post and the edge, tap the screwdriver firmly with a hammer to loosen the screw, grip the screwdriver with pliers, and remove the screw.

- Use a hacksaw or Dremel tool to cut a slot in the head of the screw, then use a flat-bladed screwdriver to remove the screws. (Use safety glasses).

Once the cover's off, you can see the door opening parts. It's probably the lever.

If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. If you hear an unusual buzzing noise, the magnetron (the component that actually generates the microwaves) or other electronic module may be broken. If you hear nothing, you might have a defective transistor on the main printed circuit board. This is not easily fixed; contact a service technician. You can try the "find a microwave repair..." link from the product page. Good luck!

Turn the microwave oven to the "On" position press "Stop/Clear" a few times -- the microwave should return to normal mode.

I hope you didn't run the microwave with nothing in the cavity, if you did, it will damage the magnetron. The turntable dishes do get hot depending on the quality of the glass used to make it. Heat is caused by impurities in the glass. If you run it with no food in the oven, the glass will try to absorb the energy with atastrophic results usually.

The thermistor has failed. Replace the thermistor with the Sharp approved type and part number.

You might attempt the following troubleshooting steps: Ensure sure the temperature settings are accurate and that you have given the oven enough time to warm before putting food inside. Check the oven temperature settings. To learn how to adjust the temperature properly, consult the user handbook. Examine the heating components since they can be broken if the oven is not heating at all. When the oven is switched on, see if the heating components are blazing red. The heating components might need to be replaced if they are not. Examine the oven thermostat: If the temperature fluctuates or fails to reach the desired level, the thermostat may be malfunctioning. Replace a broken thermostat if necessary. Verify that there are no blockages inside the oven that could be preventing the heat from circulating. Debris, foil, or bakeware that is too big or that covers a significant amount of the oven rack might all fall under this category.

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? IanFromOhio a year ago 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. Reviewed on bestbuy.com
