The outer casing has to be removed, inside you will find a large fuse 10A> this protects the transformers and magnetrons, also you will find some smaller control circuit fuses, they are normally mounted on the circuit board at the rear of the control panel.

Yes, Sharp microwaves can blow the main and subsidiary fuses for no apparent reason. Be absolutely certain to replace them with the correct types - CPC sell them in the UK, they are cheap.
Eventually, I fixed a machine with this fault by lubricating the door triggers and microswitches with silicone grease and switch-cleaner aerosol, respectively. No further problems. Looks as if grime/oxide on the surfaces was causing transients.

Sharp Carousel Model R-209KK-W is flashing all 8's and keypad not working


The first thing to try is to do a hard reset.

Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

If it still doesn't work, it may need repair, which can be done for $39.95 in most cases.

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 Microwave has no power


I too believe that a "protection fuse" was possibly blown. It would need to be found and get replaced. Hopefully it is just a fuse and nothing else because the way it sounds to me, the microwave may be damaged.

Good Luck!

Sharp Carousel Microwave R-1460A no power, door switch went first


You will want to replace the fuse and door switches. You will not be able to run it without replacing door switches. You do not need a new microwave. Door switches go bad, it has nothing to do with radiation.
