    The blower fan is only working periodically. Not working more often than it is working.

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:$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:
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,

The microwave light and fan stops working,but it still heats.

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.

I have a frid microwave FMV145KB2 that has stop working

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!

What is a stirrer cover, the plastic part over the fan inside the top of my Sanyo microwave is burning.

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

Noise while not running

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
