OTR Microwave Alternative Bolts

I have a project I need to knock out today. The microwave I picked up from a yard sale doesn't have mounting bolts. I am wondering what's an alternative size bolts that can be picked up from HD, Lowes?

Your going to need to mount into the wall studs so I'd get something 2 1/2" - 3" long.

Does the microwave have the mounting bracket? Typically the bracket mounts into the wall studs with 3/16" or 1/4" lag screws. I think the bracket is a must have. If the bracket holes don't line up with the studs you can use round head bolts and toggles.

You will probably need to mark and drill holes through the cabinet for the top screws. The microwaves that I have installed use 1/4"X20 3" flat head bolts through 1/4" flat washers.

Here are the model numbers. The first one is GE but sure about the second one.

Also got those , 1/4"X20 3" flat head bolts, didn't fit in either one. The second one has one bolt and it fits in both. Comparing it with the 1/4"X20 3" flat head bolts, it has finer threads, ie threads are much closer if you will, bolt on the left. Will see if they have it at HD.

Installation Kit for the GE is P/N WB01X10132. It is not stocked by GE but you can get it elsewhere. It does not include the mounting plate. The 3 flat head screws for this microwave are dog pointed for alignment. They may be 1/4"X28.

These bolts here fit the GE MW but not the other one.

The other problem is the fan is not running but the unit works ok. Where to start to T/S if it's indeed the fan or something Else?

WB26X10134 circulating blower.
Black = hot/high speed.
White = hot/low speed.
Red & yellow = 10uf capacitor.
Blue = neutral.

Use a voltmeter and see if you get high and low power..... black or white to blue.
If cap is bad you should be able to push start it.
If you do.... the thermal limiter probably blew open inside the motor.
The part number is above. Several for sale on ebay.
