20 Most Recent Sharp R-1200 Microwave Oven Questions & Answers

Hello William,I see you got back to me and I dowloaded the manual, but not sure how to repair this microwave, the inside light is burned outand the display numbers do not light up correctly, as if some of the pixels are burn out. So I need to know what I need to replace ( LCD panel)? where is the bulb located and how do you remove and replace it, It should be easy once I know what and where to go

The cover is a Wave guide cover and behind this cover are critical components. The arc is caused by a defective component called a magnetron. The magnetron creates the wave pulses that cook and heat during oven operation. At this point, it would be much cheaper to replace the microwave.
I would not recommend servicing or removing the cover yourself. There is a high voltage capacitor that stores high electrical current that can cause severe shock or injury.

We have the service manual and have uploaded it to our site here to help you.

You probably have a failing door switch or the mount which holds your door switch is loose or broken. In most designs, it is the upper door switch that will produce these very symptoms when it is intermittent or its mount is broken or loose. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. Slamming the door, damage during shipping or transportation and sloppy manufacturing techniques or materials are the primary causes of trouble with the door switch mounts. I have a text file called "doorsw.txt" which helps in diagnosing and repairing door switch problems, and a file called "safety.txt" which is of vital importance. If you or a friend decide to work on it, we have *critical* safety and disassembly info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk

It may be a bad fuse inside or it could be blown circuit protection on the control board caused by a power surge. The former you or a friend can fix, the latter we repair nationwide for only $39.95.

In my professional opinion, power outages can kick a failing or weak unit over the edge, so to speak, but the primary causes of these display failures are the design and manufacturing techniques. We regularly remedy and repair these very units nationwide for $32.50, and our proprietary fixes make them better than new in my opinion, with the aim of not only fixing the problem, but preventing them from recurring. When we repair them, we have folks send us the outer door panel with built-in keypad & display assembly, the power board, and the connecting cable. Thay way we can power and test the unit as an assembly. It's better to separate the door panels instead of removing the door. I have attached a drawing to show how. If you remove the door instead of just taking off the outer panel, the microwave will have to be tested for microwave leakage, which can occur if you haven't reassembled the door with all the hardware in the exact same position as it was. So rest assured this can be economically fixed.

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

Touch STOP/CLEAR pad.

Touch TIMER/CLOCK pad again.

You have to replace the control board. Sharp has had problems with the display boards for awhile. There is no bulb or fuse you can change.
