I think there are some electrolytic capacitors in the power supply to be replaced.Because there are relatively few, it would be good to change them all for more safety

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 Microwave stopped working. lights up, counts down. Fine'


High voltage power supply for the magnetron is likely problem. Multi-thousand-volt section--be careful.

Sharp microwave losing cooking power


If the supply voltage is low it will take long time to heat foods. The second reason is the Magnetron. Since it is in the warranty period you can call at the sharp authorised service center. They will do it free of coast.

Sharp 1870 just quit cooking and no turntable


The fact that the microwave and convection both do not heat indicated that the oven is in demo mode, check the user manual, otherwise it will possibly be a relay not triggering, may need a pcb replacement, check Demo mode 1st....Phil

Was using microwave to pop quite a few bags of pop corn to feed birds. Microwave is hot to the top to the touch. lights on the front of the microwave are not lit up, no power. WALL RECEPTCALE is active.


Plug fuse may have blown. Replace that first or test.
Internal temperature trip may have cut out (if present)
Microwave generator (magnatron) may have failed.
Internal power supply may have failed due to moisture.

Very likely this machine is dead.
Save energy - and cash, by feeding birds stale bread and raw seed and corn.
Hopefully the next microwave oven will last longer.

The cost of repair may be more than the cost of replacement. Ask your nearest repair shop how much to replace the microwave unit, and check the power supply.

Sorry I can't offer a quick fix for you.
