Question about Sharp Microwave Ovens

Open Question

I have an ancient microwave from 1983. Sharp Carousel II. It worked great up till recently. All the sudden it started running when you opened the door all without any time being set. It was heating fine. If you unplugged it then put you stuff in it heated normally (it is amazing how much we use depend on it) so hubby replaced the door switch. He usually solves stuff but a few days later, now it starts and stops like it is supposed to but does not heat. Any suggestions, I know the obvious is cheapo buy a new one, but this one has been so good for so long..... Any suggestions?

SOURCE: microwave runs constantly

If it's less than a year old, it's under warranty and you should call the nearest Sears store for free repairs. Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams and order parts by entering your full model number here: http://www3.sears.com (the 3 is correct)

SOURCE: Microwave automatically comes "on" when door is closed, but no heat.

I have the R-1460 in the same series with the identical symptoms. After reading MicrowaveSvc's solution I started taking apart to view the door switches and found the upper door switch to be the problem, but not a switch failure a support failure. A small bottom plastic support post that holds the switch in place was broken (probably from repeated use/abuse) allowing the switch to move when the door hooks were engaged, thus not actuating the button switch. Since the problem was mechanical rather than an electrical bad switch, I made a small support arm for the switch from an old plastic mechanical pencil and glued it in place to hold the switch in its correct position. Problem solved, microwave works! Thanks to MicrowaveSvc's description of door switches.

I just had an appliance repair man check my Sharp R-1870 microwave for the 59 second shut off problem. He said it was the main circuit board. Has anyone run into this problem. Everything I google says...


I've had a similar problem with a 1983 Sharp Carousel microwave. It turned out to be a faulty door micro switch, the contact didn't stay closed inside it for very long.

My sharp carousel II microwave no longer heats food. Do I need to buy a new one?


The problem maybe the magnetron, or the inverter board if 7 years old or less, and possibly the keypad control board, by the time you add parts and labour cheaper to replace the microwave oven in the long run.

Built-in Sharp Carousel II Microwave Convection Oven died.


There are a couple of safety thermostats in the oven to shut down power if something overheats. One is on the magnetron tube (the microwave source), the other is on the cooking cavity. These sometimes go bad. There's also a power line fuse that may have failed, or become loose in its mounting clips. These can be tested with an ohmmeter; they should all measure very close to zero ohms if they're good.

Another possibility is that the control circuit board in the oven may have failed. I have worked on several Sharp ovens where the power transformer for the board has gone bad for no good reason. If the board goes bad the oven may appear to be dead as well.

Microwave servicing is best left to professionals. If you're thinking of keeping this one, take it to a service shop (or call for home service) and get an estimate. Then decide whether to repair or replace.

Hope this has helped a little. Thanks for using Fixya!

Sharp microwave stopped working


Is it totally dead? No display? Or just does not cook? If it made an unusual noise before it 'died' something probably shorted out.... You need an ohm meter to troubleshoot. If the fuse is open, switches and HV circuit need to be checked before replacing fuse. Sometimes on the convection Microwaves (not just Sharp) the fuse will 'rust' and open rather than blow. Or the fuse holder can over heat and fail.

Sharp carousel II microwave/convection oven


The question is... Do you want to put money on a 18year MW, or put it towards a new one? I must admit I love the SHARP Combo MW Convection ovens. I own two. One is almost 25years old. The mechanical Timer Type, but they work great and I can maintain them with 30years ef exrerience. I am now retired.
It does sound like the Magnetronhas broken down, however it could be other things in the Secondary (High Voltage Side). The High Voltage Side is made up of the Secondary HV side of the High Voltage Transformer, A High Voltage Diode, a High Voltage Capacitor, and the Magnetron. The High Voltage Side is DANGEROUS, and CAUTION should be taken to protect yourself against EXTREME HIGH VOLTAGE. unplug from power and DISCHARGE High Voltage Capaciton to frame GROUND before touching anything!!!!
