Sharp microwave oven r-9h20 display flash(00:00)) and no keypress action

On Sharp R-9H-series ovens, when the membrane keypad fails, as in your case, since these parts are no longer available, the oven would have to be retired.

Sorry to bring you bad news. These were great old workhorses.

I have a panasonic microwave oven. It shuts off after running for just a few seconds. It does not flip any circuits. The model # is NN T785SF.

It thinks its overheating, and the (faulty) thermal shutoff is shutting down your unit.
fix: since repair parts for household appliances are unavailable (parts are available for major
appliances only), your fix is to replace the microwave.
Or give it to the handy kid down the block who will disable the thermal shutoff and use it to
melt plastic stuff for demented puerile YouTube videos...

I'm getting conflicting directions on how to replace a fuse in my JVM1440...Is there more than one way to access the fuse. One said to take the MW off the wall, remove the case, then have access to...

Hello there and thank you for choosing fixya
Actually the unit does in deed have to be removed from the wall because the outer shell does need to come off there is a series of screws on the edge of the back that need to come off and there are some on the sides then the outer cover will slide to the back about 1 to 2 inches then lift off and the fuse is on the control board towards the front right as you are looking at it from the front of the microwave ok
Hope this helps best regards mike

Microwave not heating.

1 thing here you can check yourself. You need to remove the cover of the microwave. Make sure it is unplugged first. To remove the cover there should be a series of phillips head screws on the backside of the microwave. Once the screws are removed then you need to lift the back of the case towards the front there is a lip at the front that holds the front down that is why you need to lift the case from the back. Once you have accessed the inside follow the powercord from the plug into the microwave along this cord you will see a fuse. Very IMPORTANT do not touch both sides of the fuse holder at the same time. There is a charge stored in the microwave that will curl you hair remove this fuse with a fuse puller (purchased at an auto parts house) Take the fuse to an appliance parts house for replacement. Should be in the area of 10.00 or so. Replace the fuse put the casing back together and try the microwave. If it doesn't work then the magneto or magnatron whichever the machine has is blown and in that case it is cheaper to buy a new microwave
Good luck hope this helped you some

How is the capacitor connected to the magnetron, the diode and the trasnformer in a Maytag microwave - MMV5156AA

The magnetron is a tube with a heater/cathode element in the middle of a series of scallop-like grooves that surround the cathode, but spaced away from the cathode. A small, insulated wire protrudes into one of the scallops and extracts the microwave energy that passes down the wave-guide, past a fan-like device called a stirrer that scatters the energy just before entering the cooking cavity.The magnetron requires a low voltage/high current AC heater supply plus a 3000 to 5000 volt DC supply that is hooked to the cathode of the magnetron. The transformer supplies both voltages as AC waveforms. The diode makes the HV AC supply into HV DC by passing current in one direction only and the capacitor stores/smooths that HV DC into relatively stable DC for connection to the cathode of the magnetron. The other side of the DC supply is tied to case ground as is the outer case of the magnetron. This arrangement is typical of all microwave ovens (and radars).

Primary intelock switch on a Sharp R-520Lk continues to fail

That switch carries the current of the turntable motor, fan motor, and the high voltage section.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

It causes a spike at opening that eventually arcs and pits the contacts inside, and it can cause melting of the case.

You should check the switch mount for cracks, too.

Sometimes excessive current can make them fail too, but your fuse should blow before the switch.

We have the full service / repair manual for this model and have uploaded it to our site here to help you.

It will give you safety info, step by step help in disassembly, troubleshooting tips, and part numbers.

You will need the
free Acrobat Reader to view or print it in case you don't have it already.

If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.

We're happy to help you. Once we have all your information and offer a final solution, we'd appreciate your thoughtful rating of our answer.

Need New Microwave

Is the interior flaking the only problem with it?

It can be sanded smooth and clean and dried thoroughly, then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

Otherwise, if you want to replace it, I would suggest contacting Jenn-Air Customer Care here and telling them your model number.

They can probably give you the model number of a new "drop-in" replacement.

I have a Sharp Micro Wave Model R 1512 F that the start minute plus key is broke. This is the third time and I would like to fix it myself. I can not afford another service call on this one, How do I fix...

You can order a new and improved select button assembly here.

We have the service manual for this model and have uploaded it to our site here to help you.

That, plus the R-1500-series service manual here will help you safely disassemble it so you can replace the select button assembly.

Also at our site, we have a video available how to remove a typical over the range control panel assembly in under 5 minutes.
