The most likely sources of the funny sound would be the high-voltage diode, transformer or the magnetron.

 

It's possible that the high-voltage capacitor shorted and blew the fuse.

 

It will take some troubleshooting.

I have a 1995 Sharp Carousel R-1440. Our power went out then when it came on our microwave it no longer working properly. the clock works but when the door is closed the cooling fan starts running- it...


Yes your oven's controller is probably malfunctioning you need to replace the SYSTEM BOARD but I personally suggest to buy an other oven.... the system board will be hard to find and expensive...

See if other electronics is acting funny since the power loss... you could CLAIM the damage from the insurance company

Good luck!!

Boiling water caused large "Pop" sound/microwave not working now


I would guess that the boiling water may not have been the cause ...
If you are lucky ... try this first:
Unplug or turn the circuit breaker off (if it is a built in unit). Wait an hour and then repower.
Odds are that will not clear things up ... but it is easy to try. Probably one of the electronic internals broke.
A number of different internal component problems could cause this heating failure in the microwave. It could be the magnetron, the high voltage transformer, the PC board, the diode, and the capacitor. This type of problem will need to be diagnosed and repaired by a service technician. Microwaves are inherently dangerous to service. This type of repair is not something that you want to try to do yourself. Internal capacitors in the microwave can retain a lethal electrical charge even when the microwave is completely unplugged. A microwave radiation leakage test should be performed on the unit using proper testing equipment following any internal component repair.

R9H84B Sharp Microwave Convection from 6-6-1997, power stopped and turntable stopped. Light works and sounds like the power is working but nothing gets hot.


Is this the unit with the door that swings down like a conventional oven?? I think it is. This sounds like a door switch but could be a magnetron or cook relay on the control PCB.
