Blower The microwave is working but I don't here the fan/ blower. it stopped one day and that was it. I am worried that the microwave could burn out if I continue to use it. Is that possible?

The support page for your microwave series is here. It has the owner's manual, installation instructions, and exploded view with parts lists.
My favorite supplier of microwave parts would be the Pros here.
FixYa doesn't notify us when there's a response, so if you have other questions, please contact me directly.

Hi and welcome to FixYa, I am Kelly.

I am having a hard time grasping the problem here. I have to assume that the microwave fan is the problem and not the blower fan. No worries.. ALL of your questions can be answered by this manual if you understand Technician procedures:
https://secured.whirlpool.com/Service/SrvTechAdm.nsf/0/52015b2c875fae4d85256a8c0062547e/$FILE/4322167.pdf

The cooling fan should be running any time the turntable is moving.

Fan motor is item 1 this link:

This is the fan motor: http://www.appliancepartspros.com/part_details.aspx?part_id=3034166
It can be lubricated with a parafin based oil (Zoom Spout turbine oil) of Union 76 turbine oil. It is best to remove the mounting screws for the motor bearings and then clean the motor shaft & bearing before lubrication. Do this on both sides of the motor. Most of them can be revived with proper cleaning and lubrication.

Thanks for choosing FixYa,
Kelly

If the fan doesn't work the magnetron may overheat and burn out. Look for a seized motor.
The light may be just a blown lamp.
Hope that helps.

if the magnetron is shot, then replace the microwave! the magnetron is what produces the 'microwaves' that do the heating. get rid of it! buy a new one! the smell is from overheating circuitry- don't want to take the chance of a fire!
these days you can replace it pretty cheaply- with a fine piece of technology made in china! but, if it lasts 3-4 years, it's pretty cost effective.
once again! if your getting a 'burning' smell from it, unplug it and dispose of it!
good luck!

That burning part is referred to as the stirrer cove, unless you have one similar on the bottom.It's like plastic pie plate. The fan stirs the microwaves and heat in simple terms.

Unless food is burning off it , I would be replacing the unit or have a qualified, trained microwave tech service it. You need a microwave leak detector to work on them safely. Given the cost most are disposable these days. Be Safe on this one

don;t worry;
all you need to do is lubricate the fan bearings with light machine oil and make sure the fan is not hitting anything

Are you sure it is the internal blower and not the VENT fan ?

check the control bord, and blower fan.

We see this a lot. The problem is probably on the control panel, which we regularly repair nationwide for $39.95 postpaid.
