Top cabinet nut on microwave fell into the microwave...what do i do now?

In the top of the microwave they have nuts with clips on them that snap into the outer cover. If the mounting bolts were not started carefully they could have been cross threaded and now those nuts are spinning in the cover of the unit. THAT may be a bear to remove. Can you take off the grill on the front of the unit above the door and see if you can see the bolts coming down into the unit?? If so, you may be able to grab the nuts to keep them from spinning to get the bolts out. Sorry , doesn't sound fun!!! Good Luck!!

there should be screws around the back and at the front corners at the bottom then it should pull off

You may find it has security type bolts that require a special bit, take a good look to see what the bolts that secure the cover look like.

the screws are in the GRILL ( FRONT TOP ) of micro NOT in the top as in Attached to cabinet.

HI,

Frigidaire makes several over-the-range microwave models that are all installed in the same manner. To install correctly, you must have at least 45 1/2 inches from the bottom of the top cabinet to the cooking surface of the stove to provide enough clearance for the microwave. The top cabinet must also be at least 30 inches wide and 12 inches deep. Find someone to help you, then follow the steps below to install your Frigidaire microwave.

Things You'll Need:

• Stud finder or hammer
• Screwdriver
• Drill

Instructions

Pull your range away from the wall so you can work comfortably. If this is not possible, cover it with a drop cloth. Find and mark the locations of the studs in the wall behind the range. They will be either 16 or 24 inches apart.

Follow the instructions on the wall template to mark the location of the mounting bracket and the four anchor holes on the wall and the bottom of the cabinet. Drill the anchor holes. Follow the instructions on the top cabinet template to mark and drill the two holes in the bottom of the cabinet.

Attach the mounting bracket to the wall studs using the six wood screws included with your microwave. Screw the toggle nuts onto the toggle bolts and push one through each of the four drilled holes. Screw each toggle bolt until the nut is snug against the inside of the wall.
Pick up the oven with your helper. Plug the oven into the outlet and slide the oven onto the mounting bracket arms. Push the oven back against the wall. Tighten the two screws on the microwave faceplate to fasten the microwave to the mounting bracket arms.
Attach the louver to the top of the microwave with the three provided screws. Insert the two top cabinet screws and washers from the top cabinet into the microwave and fasten tightly.

Take care.

Jim here. In cabinet above microwave, locate 2 mounting bolts.
Place a box on the stove top to support the microwave once the mounting bolts are removed (you may wish to cover the box with a thick towel or small throw rug).
Procedure:
1. Unplug microwave.
2. Remove both mounting bolts from top of microwave (they secure it to the overhead cabinet).
3. With microwave front angled down onto box, pull some of power cord out of hole (to provide some moving space).
4. With microwave hand supported, remove box from stove top (a second set of hands would be helpful here).
5. HARD PART- detach top of microwave back from wall mounting plate by placing a hand under the bottom rear of the microwave and pushing up. (Wall mounting plate is screwed into the wall behind the microwave and provides both top and bottom support to the back of the microwave.)
6. Lower front of microwave until you can see about a 1-inch clearance between the top-rear of the microwave and the cabinet above it.
7. Firmly lift the microwave straight up and then bring forward. It should be free of the wall mounting plate.

There are two thermal fuses.

One is located on the magnetron and another one is located on top of the left side of the cavity under the air duct. The microwave has to be removed from the cabinet to access the second one.




The problem turned out to be a 20 amp fuse that I was able to replace and the unit is working fine. Sometimes a blind squirrel finds nuts.

Use a magnetic retriever to to recover the nut , then use super glue to fix it back in place

If you are referring to an over your stove combination microwave/ vent system then they are typically secured thru the cabinet above them. Try opening the cabinet directly over the oven ( you may need a step ladder to see the mounting hardware) and look near the front of that cabinet for two screws on the bottom of that cabinet. These two screws go thru the cabinet and support the front of the microwave oven. You may also see the power cord for that mircrowave oven plugged into a receptacle inside that cabinet. Unplug that cord and then begin unscrewing the two screws. ( it's best if you have a helper work with you).. as you unscrew them, the front of the microwave should begin to drop down a bit. Once the screws are removed, you should be able to lift the back panel up a little bit to free the microwave of the wall mounting bracket. Once that is doen, you will be able to remove the microwave. I am assuming that your microwave does not have any vent pipe secured to it. If it does, then you will need to seperate that from the microwave vent on top ( assuming it is venting thru the top) .. These microwaves can be vented in any of 3 ways, thru the top, outthe back or configured to vent back into the room. In any case, you should see ductwork while removing this from the cabinet. Hope this helps you get the job done...
