Check you coolant level(gurgling sound). A sweet smell is most likely a leaking heater core. Burning oil is valve cover gaskets.

Are you loosing radiator fluid. sometimes the heater core will rupture and you will smell burn odor. also check for strange rubbing sounds or screeching coming from the blower fan motor. or engine exhaust manifolds are hot when car is on, make sure nothing is leaning on them which will cause a burn odor. Any odor coming from outside will find it's way inside through the fresh air vents.

Good Afternoon Friend,

I understand that you are receiving a burning rubber smell from your Frigidaire microwave. I also see that your appliance will run for a couple of seconds, and then you hear a weird noise, followed by a burning rubber smell. I suggest contacting your local authorized technician, especially when dealing with your microwave. They will be able to diagnose your appliance and determine what is causing that sound as well as the burning rubber smell. Hope this is helpful.

If the burner is off and the fan is still running and you still have the burning smell then your fan is on the way out .

You most likely either have a loose belt and it smells like burning rubber or you have a small animal caught in the belts.
Replace or tighten the belts and you will be happy

Thanks

Sounds like the motor burned up when the ice blocked the air which it was not able to cool the motor it will need to be replaced. (the motor)

The centrifugal clutch needs replaced.

If the motor sounds scratchy and is making a burning smell, or sparking you will need to replace the motor or the entire vac. Carbon brushes will rarely fix this as it is a high RPM motor

CHECK THE OVERLOAD/RELAY ON THE COMPRESSOR. THE RELAY COMPONET IS BREAKING DOWN AND CARBONIZING CAUSING A BURNING SMELL. THE PART WILL SOON STOP WORKING AND THE COMPRSOOR WILL NOT RUN. IT WOULD BE WISE TO REPLACE THAT PART ASAP.
