Pin hole in back wall from metal carousel hitting wall while oven on

There is a small pinhole in the back wall at the level of the cooking tray - the tray 'skipped' and hit the wall of the oven causing a spark and it melted the metal on the wall of the oven. Is there a 'tape' I can use to cover this pinhole? Do I have to replace the whole oven?

You can buy stainless steel tape from many hardware stores, just make sure that you put the tape on the outside (be very careful when opening the oven up). Put enough layers on to match the thickness of the metal originally - unfortunately the tape tends not to stay on for that long, so is potentially a dangerous option the best thing to do would be take it to a microwave repair shop - they will have metal sheet available of the appropriate type and should be able to patch it for you - if you get really lucky they might have the same model that has an undamaged chassis but destroyed electrical workings - is worth a try. Good luck Hope this helps - please post again if you need more info :)

The turntable quit turning

The root will depend a bit on your microwave model. A few things to try:
  1. Take the (probably glass) tray that is rotated by a spindle in the middle. there should be a shaft with some sort of indented head matching the backside of the turntable. Is it covered in old multiply-nuked spaghetti sauce or other food cruft? If so, wipe off what you can, spray on some Simple Green or similar and let it sit for a while, try putting a washcloth with scalding water on it for a bit, whatever will soften up the gunk and let you wipe it off.
  2. Try to turn the shaft. Will it move at all? If grippable, can you gently grip it with a pair of pliers and get it to move at all? There may be a gear train under this to let some small motor do the turning with enough torque, so don't force it. All you're trying to do is see if the shaft has some wiggle to it and isn't physically stuck in place.
  3. Check the rollers - usually there's a ring with 3 or 4 small rollers between the carousel tray and the microwave cavity floor. Make sure that the rollers roll. if not, clean them or work them to get them rolling again. usually this part comes out and can be thrown in a bowl of soapy water to soak for a bit without harm.
  4. Many of these carousels will detect if something on the carousel is hitting a wall, and either reverse direction, or stop. This is since the inside is square, but the rotation area is round, so something sticking out on a diagonal at cook time may hit a wall. These mechanisms don't want to force the turn - you might overturn or break whatever is being heated, and make a mess. If that's the case, you might see if the shaft will turn with no carousel plate on top. IF so, something was stuck.
  5. beyond that will go into the specifics of the microwave model and how it's set up. I hope this may be of help!

    Good Luck!

Sparks when cooking

Make sure no metal item (forks-spoons or oven rack) is touching the outer wall of the microwave. That will cause sparks. If all that is OK then there is usually a metal fan type blade in the microwave top called a stirrer blade that may be out of place and rubbing the cavity causing sparks. Try to pin point the spark area so you know where to look for the problem. Sparks usually mean metal is touching metal somewhere.

Sharp R-1510 1000 watts microwave, not heating

Sounds like the inverter (power supply for cooking) or the magnatron which does the work----neither are cheap parts.

Sharp carousel R 430 EK 1200 watts

This is not good, the magnetron is arcing because metal is exposed, this will eventually destroy the magnetron making the oven useless. I strongly suggest it get looked at for safety and potential fire hazard.

I have a Sharp Carousel over the range microwave model R -1601. I cleaned it and now it sparks when we try to use it. What can I do to fix this problem?

The cleaning operation may have spread metal particles or other conductive materials on the walls/floor of the cooking cavity. Try wiping the entire cavity with a damp, clean cloth, then heat a cup of water for a test. Hope this helps!

I have a Spacesaver Microwave (manufactured 1988) that still seems to work ok, but I noticed on teh back wall under the glass tray the coating has rusted away. Should I continue to use this microwave?


As long as the oven's metal bottom is sound underneath the rust, there isn't a problem. The cooking chamber walls are so thick and highly conducting that they reflect the microwaves extremely well even when they have a little rust on them. However, if the metal is so rusted that it loses most of its conductivity in the rust sites, you'll get local heating across the rusty patches and eventually leakage of microwaves. If you're really concerned that there may be trouble, run the microwave oven empty for about 20 seconds and then (carefully!) touch the rusty spots. If they aren't hot, then the metal underneath is doing its job just fine.

I have a Sharp Carousel microwave model R438DV 1200 watts. There is a small 5x7 screen on the right side wall. It now has a small hole and has char marks on it. When I use the unit a fire starts o

You have to replace that small screen which is called wave guide. If there is a sharp authorised service centre near to your place you can buy the part from them. Do not work the oven without replacing that part.

Hi there - I assume you have a rack in the Microwave. What happens is the rack due to putting something in and out of the Microwave some times wears against the back wall of the cooking chamber. As this happens it wears through the paint and exposes the metal casework.

You then get microwave arcing between the metal rack in the microwave and the cooking compartment casing which gives that spitting popping sound. I would say get some white model paint and paint over the scorched spot (as long as its not gone so far as to wear a hole in the case work).

Wait for it to dry and stick the rack back in and try again to warm up a cup of coffee or something and see if it stops.

Also if you pull the grill slightly forward in the holders towards the door and test it you may notice that it doesn't pop as much so I would paint it and pull the grill forward and see if you still get the issue.

Best of luck.
