Hello Dwight,

You may have damaged the microwave. Since the oven cavity is a tuned cavity, introducing metal into it can wreck havoc on the magnetron (microwave generator itself).

Did you happen to notice if the smoke was from the plastic jar (plastic heating up from the high temp of the foil ring), or if it was the actual microwave smoking (and not blowing smoke out of the oven cavity from the plastic jar)?

Maybe. The presence of metallic material (foil, stainless steel silverware, etc.) in an operating microwave oven creates electric arcs between the foil and the inside wall of the oven. And this can destroy the electric components.

Sharp r520kst door won't stay shut


If the door will not stay closed it is the spring inside door, or the small plastic piece that holds the spring which is attached to the $80.00 piece called outer door.
To fix it, it is EASY and you do not have to even take the inside cover all the way off. Just remove the three sides of cover by gently slipping a plastic putty knife around rim to release the clips. Then attach the spring to the small hole below where the plastic piece used to be, which is located in the metal on the glass frame piece, use tweezers, hold the other end of spring as you place spring onto plastic door latch and set into place!
Snap the inside cover back on and YAY! FINI!

My nanny stuck a piece of chicken wrapped in aluminum foil into the microwave for 30 seconds ... naturally: diasaster .... the front glass is 'burned' in a small spot but I think it is a 'hole' ... still...


There is a plastic inner sheet that covers and protects the metal mesh that's in between the door panels.

If food, grease, or moisture gets on the metal mesh, it can be damaged, which can cause leakage, resulting in arcing and possible fire.

So the inner sheet must be repaired or replaced.

If the hole is not too big, you can use an Xacto knife or razor blade to cut away the damaged part, then clean & dry it thoroughly, and apply a small piece of clear packing tape over the area.

Otherwise, you can replace the sheet.

Microwave seems to operate normally but does not heat food


Test it. Put a bowl of water in the microwave and place a small (1 or 2 sq inches) piece of aluminum fold next to it. Power the microwave on for 2 or 3 seconds. If the foil sparks, the oven is creating microwaves and should be functioning correctly. If nothing happens to the foil, then you have no microwaves being generated by the klystron tube.

You can spend 80 to 150 dollars to have the oven checked and repaired or you can find another on Craig's List in your community for less than 100 dollars. Alternately, you can replace with a new one for whatever you are able to spend (from 95 to 600 dollars).

Reset clock, ge spacemaker xl1800 times out after 2-3 seconds


There's a simple fix for this. Unplug the unit. Take off the top grill with 2 screws. Remove the 1 screw that holds the touch pad unit. Lift up on touchpad unit and lift out. Put a piece of aluminum foil inside a large zip lock bag and tape it to the back of the touchpad unit and reassemble. GE put the magnetron to close to the control board causing stray microwaves to interfere with the board. The foil shields it.

Sharp R-1510 Start Button Not Working


This may not solve your problem, but on my Sharp R315J microwave, the little plastic pin that pushes forward on the inside of the start button, had broken off and it wouldn't start. The Minute Plus button would start the microwave, so I knew the microwave worked, so I tried to find a piece of plastic that I could glue into the start button hole, because the part doesn't exist and you have to buy the whole door for $100 plus shipping. Nothing I could find was small enough, so I started looking for a new microwave.
While ouside doing lawn work I noticed a small bird tail feather and the end looked to be the perfect size. I snipped off the pointed end and then up about 3/8" to make a little rod to replace the plastic one that broke. It fit perfectly!!! I didn't even have to glue the inside end, it stays put even after repeated door opens. This is sturdy material and looks to last a long time. When it wears out, I have a cat, there's always a few feathers around. I hope this saves someone else a hundred bucks, like it did me.

If you put metal, like an alluminium foil into microwave, the magnetron will start arching, and you will damage magnetron, diode or capacitor.

Test the high voltage capacitor, the rectifier diode.or the magnetron. If all this are fine, test the control board.

The diode and capacitors can br tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, even if power is off. Capacitors can get discharged by shorting their two contacts.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.

All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts. (here in UK).

Hole in plastic on inside of door


check the conductivity of the plastic with an ohmmeter by placing the probes an inch apart on the plastic surface. If the resistance is large or infinity, the plastic probably performs no role in stopping the microwave radiation. If so, any epoxy probably can be used to close the hole safely. Make sure you don't use too much and if possible place tape over the repair and orient the microwave so the epoxy presses against the tape while drying to prevent it from oozing into any door hinge/close mechanism. Otherwise, a piece of microwave door glass from a broken unit can ge glued over the hole and should stop the radiation. You can check for leakage with test units but be very carefuly anyway.

Microwave shuts off after a few seconds


Nov 22, 2007. I also had the 3 second shut off problem with my G/E 1650 MWO. Read all the above and tried them all. Finally I just took a 8" x 8" piece of Reynolds Wrap Aluminum foil and but it in an zip lock bag and placed it behind the control panel. It's been working for 2 weeks now. Just take out the 2 screws that hold the vent across the front right above the door. Next on the right side is one screw, take it out and then gently lift the control panel (panel with the buttons) about 1/2" and it will fold out and stay there. put the zip lock bag inside. Close it back up. I'd test it before replacing all the screws. You don't need to un-plug anything. Just don't stick your fingers on all the exposed parts...Mine works great now and didn't cost $0.10.
