If you have no power what so ever its probably the main fuse inside the mirowave. You'll have to take it apart. If you try this yourself unplug it then there are several screws around the cabinet of microwave remove them and make sure that they go back where you took them out from because they may or maynot be the same size or length. once you get the cabint off follow the plug wire up into the micro wave there may or may not be a fuse on the wire just inside the frame of the Microwave but it will be close when you find it take it out and replace with the exact size take it to a appliance parts store and get the replacement.

Testimonial: "Thank you! Replaced the fuse, power came on, but blew under load. Old micro, time to chunk it. Thanks for the $2 troubleshooting suggestion! Karen"

    Well if it blew it again you have more problems. if you want to try to fix again I give you a couple more things to check. Thermal protector or a thermal fuse around 5 bucks

MODEL R-395Y sharp carousel microwave not working. All power outlets are fine. Please help, cheers lyn


I was unable to locate a service repair manual specific to your microwave; sorry.

You'll must likely have to find a Sharp service and repair center.
I've attached a link that contains the user's manual to your microwave...it has the phone number and address of Sharp; perhaps you can phone them and ask where a repair center is located.

This is the diagnostic check list Sharp recommends before calling for service:
SERVICE CALL CHECK
Please check the following before calling for service:
1. Does the display light up?
2. When the door is opened, does the oven lamp come on?
3. Place one cup of water (approx. 250 ml) in a glass measure in the oven and close the door securely. Oven
lamp should go off if door is closed properly. Press the INSTANT COOK/START pad once.
A. Does the oven lamp come on?
B. Does the cooling fan work?
(Put your hand over the rear ventilation openings.)
C. Does the turntable rotate?
(The turntable can rotate clockwise or counterclockwise. This is quite normal.)
D. After one minute, did an audible signal sound and COOK
indicator go off?
E. Is the water inside the oven hot?
If "NO" is the answer to any of the above questions, please check your wall socket and the fuse in your meter box.
If both the wall socket and the fuse are functioning properly, CONTACT YOUR NEAREST SERVICE CENTRE

Sharp Carousel R530BK microwave won't cook unless light pressure is kept on the door button.


There are door switches and one of them is evidently out of adjustment or the little actuator arm on it is.

Sounds like the inverter (power supply for cooking) or the magnatron which does the work----neither are cheap parts.

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!

Microwave made a loud pop,won't heat,sounds like it's only on half power, makes a low intermittent hum


This is almost certainly a blown high voltage diode.

In the middle of cooking frozen dinner, instant death..


We have *critical* safety, disassembly, and troubleshooting info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk If the fuse blows a few seconds after you hit START, then it's likely that you have an overheating / shorting high-voltage transformer. Try this: Let the oven set unplugged for about an hour to cool completely. Then cook for a minute at the lowest power level. If it runs any longer than it has been, it's probably the high voltage transformer, which is no longer available, but will run about $95 if you can find new old stock. If the fuse blows as soon as you hit START, then it's likely that you have a shorted high-voltage capacitor (#RC-QZA211WRE0) which runs about $25. You can order parts for Sharp models from Tritronics at http://www.wehaveparts.com.
