I just melted alluminum foil onto the bottom of my oven...what can i do to remove it. It is a self clean and don't think i can run the self clean?

You could have burnt the foil into the bottom of microwave I would take a box razor and shave the area till there is no more foil melted in the bottom

1. Empty the Oven
   • Take everything out of the oven. Remove the racks and clean them with soap and water in the kitchen sink. Look for any loose debris such as foil or charred food and remove that as well.
     
   Oven Cleaning
   • To operate the self cleaning mode, find the switch on the range marked "Clean." The oven door will lock once the cleaning operation has started. Do not open the door until after the self-cleaning process has completed. It will take between two and three hours.
     During the cleaning process, you may see and smell smoke. This is normal because the oven is operating at a higher temperature than when it is cooking. The high temperature is reducing all the organic matter in your oven to ash. You will also sometimes hear popping sounds from the oven that is caused by the expansion of metal under extreme heat. This is normal for a self-cleaning operation.
     After the oven has completed the cleaning cycle, allow it to cool for a couple of hours. Once cool, take a damp dish cloth and remove the ash from the bottom of the oven. Wipe down the interior of the oven door and around the seal. Be careful around the seal so you do not damage it. Replace the racks back in your oven, and the cleaning operation is complete.
     
   Other Considerations
   • Clean your oven at least once every three months. If your oven gets heavy use, consider cleaning it once a month. Always run the self-cleaning cycle when you are home. Because it uses intense heat, it is best to perform this operation later in the evening or early in the morning.
     

Use a fine grit sandpaper. Don't scrub too hard, you may scrub through the heating element. Take it slow and easy -- may take a while.

Whatever happened? H2SO4 seems a bit drastic. What is the foil stuck to? Won't soaking with hot washing up water remove it?

Considering the melting pooint of glass ...

Normally, microwave travels around round surfaces (Look at the B-1 for example) If you put flat metal in a microwave, you will create sparks ... lots of em. Is it possible you have something going on with one of the wheels ... like a piece of tin foil?

At a minimum, I think id be inspecting everything inside very carefully and then give it a good cleaning.

You might want a pro in your area tale a look at this as well.

this could be caused by a shorted diode or bad transformer in the unit itself, diodes are generally inexpensive repairs and are fairly easy to perform. Transformers are quite a bit more expensive and can be more difficult to replace. The diode is the most common problem. To test the diode you can either use a ohm meter or a "AA" battery, short piece of wire or rolled up alluminum foil, scotch tape and a flashlight light bulb, to use the bulb technique simply dismantle the flashlight until you can easily access the 2 connectors of the bulb (one located at the bottom of the bulb and the other being the metal bulb casing) then take the twisted up alluminum foil and tape one end to one end of the battery ensuring the is a good connection, then tape the other end of the alluminum foil to the metal casing of the light bulb, after these steps have been performed, remove the diode from the microwave completely so all u have in your hands is the diode (they are usually connected with a flat terminal and a screw), if 2 identical flat terminals are used, be sure to make a small diagram of how the diode came out (if the white line on the diode is connected to the microwave transformer, be sure to install it the same way, improper installation can cause more damage!) now that you have the diode out simply touch one end of the diode to the battery and the other end to the untaped connector of the light bulb, if the light comes on, reverse the diode, if the light is still on when reversed the diode is short, if the light doesn't come on when reversed the diode is fine, current will only pass one way through a good diode and will pass through both directions if its bad, and in very rare cases the diode will not conduct in any direction. if the diode is fine I would have to suggest taking it into a service center or considder buying a new one as other parts can be in the $70-$160 range. hope this helps.

Sometimes the arcing itself will cause black marks inside the oven. The places where the foil was melted, (touching), likely left small metal deposits, possibly now, impregnated in the surface. It is important to remove these if possible to avoid further arcing. Remove these then test to make sure the oven is functioning properly. If so, continue to use.

Do not put any metallic objects or substances in side the oven . It will produce arcing inside the oven. Take care in future.

Search the internet for “roast chicken recipe for microwave”
Here is one just in case you don’t find one:
Microwave Roast Chicken
3 lbs. chicken
1 tsp. salt
4 tbsp. butter or margarine
1 tsp. paprika
Instructions
Melt butter in a custard cup in microwave. Mix paprika into melted butter. Wash chicken (reserve giblets, these are best cooked conventionally). Sprinkle inside of chicken with salt. Cover ends of legs, tail, and wings with small pieces of saran wrap or wax paper. Place trivet on inverted saucer or small casserole lid in 12 x 7 inch baking dish. Place chicken breast side down on saucers. Brush with butter. Cover with waxed paper. Cook 12 minutes. Remove wax paper or saran warp from legs, tail, and wings. Turn chicken breast side up and brush with butter. Cover with wax paper and cook 12 minutes more or until meat thermometer registers 180 degrees (temperature will increase to 195 degrees during standing).

DO NOT USE MEAT THERMOMETER IN OVEN WHEN COOKING!! Remove chicken from oven; cover with aluminum foil and let stand 15 to 20 minutes before carving. Note: For other weights of chicken, allow 8 minutes cooking time per pound.

To Person who answered Best Solution above,
This worked nicely thank you.
After removing my circuit board the long silver strip was intact, however where it makes the turn about quarter inch, the solder or foil seam had a break in it which I filled-gap with solder.
My guess is if the "foil" or thin 2" long strip is serving as a fuse, it would still melt again even with my solder on the shorter section, in event of overload. Also seen on the plastic area directly behind where the circuit board would mount, and where the "foil" was blown, was a small blackened area as evidence of the blown foil. 2 new bulbs and all is well again Thanks!
