Question about GE XL1800 1100 Watts Microwave Oven
I have a Sharp R-395 microwave. In the last month it has stopped working 3 times. The time is frozen on when I tried to use it. The buttons dont work and the light inside doesnt come on. The only way to get it to work is to turn the power off. (It is in a wall unit and the power cord is behind the oven.)
Any suggestions would be greatly appreciated! :)
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.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
