I have a sharp microwave, model #R-1470. It's about 14 years old. I went to use it and it sounded like a power surge and then lost all power. I checked the electrical outlet and it has powere to it. Is their a reset button or fuse on this model that I could check?

Using an electrical tester you will be able to trouble shoot the issue quickly.

Go to Sharp's website and check availability of the clock/timer readout board. Being that old you may not be successful, but it;s worth a try.

either a fuse inside the unit or ?

We also have this same microwave. It is less than 3 years old. We've had nothing but problems since we purchased it. In November 2010, the microwave made a crackling sound and then BOOM! Nothing. I have been back and forth with Panasonic. I refuse to pay for the repair on an appliance that is less than 3 years old. It's ridiculous!

Anyway, the problem t is an issue with their inverters. Google it and you will find page after page of the same story.

it sounds like this is not a new microwave,, is it getting on in years?
if the microwave was discounted from the mains when it was pluged back in the power surge could have blown the circuit bord inside it,, this is quite common, it may be cheaper just to buy a new microwave than spend good money on an old week unit

There is no real safe fix. When appliances like that go bad like that it would be best advice to just get a new one to be on the safe side. You can pull off the cover with 4 screws and look to see if anything has been fried. But again, being safe is number 1

We had one that did the same thing. my brother got so mad at it he put a wrench in it and turned it on. It didn't do anything to it. No power surge nothing. It acted as if I put a plate of food. Lighted up turned and even beeped when done. The wrench wasn't even hot. Now I do recommend this myself. But we went and got antoher one.
There is something in there that magnifys the power inside the mircowave and it sounds like its out.

I have over 20 years experience with microwaves and over 25 with all other electronics, and I'll have to say it sounds to me also like some kind of power surge "scrambling" its "brains".

Or possibly its power is being interrupted for a fraction of a second and having the same effect.

A microwave should really be on its own circuit breaker.

Microwave ovens, refrigerators, toasters, and electric ovens are very high current devices.

There are power line (mains) surges created when they cycle on and off.

If the microwave can't be on its own breaker, then maybe you can try a power strip with a surge suppressor, or better yet, a power strip with a surge suppressor and a built-in noise filter.

Or it may be that there is a subtle bad connection on the circuit board or at the fuse holder.

These kinds of problems are difficult to diagnose, and even harder to do remotely. Especially since I'm in the US! *grin*

I would strongly suggest that if you can't cure this with a surge strip or similar, please carefully document when and how it fails, then while it is in a failed state, open the door (to keep it from starting on its own) and call Sharp customer service at 1300 13 50 22.

Or you could visit here and click on Service Centre Location search.

You should have a one year warranty, so you should get in touch with a Sharp-authorized repair center.

An over the range type will include home visits in the warranty, but not if it's a counter top model.

You'd have to take that type to the shop yourself, and of course that would mean unplugging it, which would reset it, and the repairman may never see if fail.

If you wait too long, your warranty will be expired, so I'd get in touch with the shop.

Good luck.

Most likely a shorted capacitor and a blown fuse. Very common problem on that model.

the electronic circuit are corroded timer does not function / the IC program was lost of memory such as function / if you have some old look a like Sharp Model you may transfer control panel.
