The power problem caused by the cook cycle starting is resulting in changes to the settings or else the microcontroller is not interpreting them properly. This may be due to a faulty part of bad connections in the controller or elsewhere. As with intermittent problems, a thorough search for loose ground and other connections and bad solder joints may locate the source of the difficulty.

My microwave has started making a slight droning sound. It has also started to have a faint smell but seems to be working ok


Sometimes the insulation on high voltage transformers gradually breaks down. It will emit an odor, and eventually fail completely, probably blowing the main fuse. The unit will continue to operate until the secondary voltage becomes too low for the magnetron to function.

Another possibility is that you have a motor with worn bearings, or binding gears. It could also have insulation breaking down in it.

I have a Sharp Model 1460A Microwave. It quit working while warming something up yesterday. Outlet is good. No power to unit at all. No light working, etc. Is there a fuse that I can check to see if it...


Dead appliance, power on wall outlet.

YOUR SAFETY IS PARAMOUNT!

Attempt this only if you are competent.

If your appliance has absolutely no functions at all, remove it from the mains supply, remove the case and see where the mains lead goes in to the appliance and follow the cable until you find the main fuse.
ONLY USE THE SAME TYPE AND RATING OF FUSE TO REPLACE IT.
The usual cause of this fuse failure is the door switches are contaminated or sticking. Check the door switches before putting power back on to the appliance.
Hope this helps.

Sharp R-1871 microwave/convection oven. Microwave will not work


This may be due to the microwave section not working. Check the high voltage diode if it is ok, replace the Magneton.

Sharp 953 as if not plugged in. checked fuses internally and external all ok. Power goes to control panel although tested with volt tester pen.


The control panel circuit board may need repair, and it's possible the low voltage transformer has failed.

Some do it yourself tips here.
