Burning hair smell coming from oil furnace

There is a strong smell of burning hair coming from the furnace, the whole house stinks...the furnace has been on atleast 20 times over the past week and there has not been any smell...could a mouse or some other furry creature have found its way into the furnace??? or is there something serious going on with the furnace itself? Could the oil be dirty????
I'm afraid to turn the furnace on again...any suggestions?

--Oh...the furnace is only 4 or 5 years old--

Thanks for your help!

I'd definately check for rodents. Maybe a
squirrel got down the chimney. If it was a small
animal it would only smell for a short time until
it burned up. Good luck and let us know what
you find !

Afraid

If you are afraid to turn it on, call a local professional.

You should not smell combustion odors ever, as that is a sign of a bad heat exchanger.

Also, if something fell down the chimney, any odor should remain outside the exchanger and not be detected in the house.

But if someone like a kid stuffed something down the heat registers or cold air return, or some bat or other creature wound up pinned up against the furnace filter, or ate it's way through it, then you could get the odor.

In my time, I sure have had lots of bats dead in the blower compartment or pinned up against filters, completely petrified. I am very cautious on even removing filters because of that.

Thanks for your replies!! AS it turned out, the furnace guy forgot to put the filter back in the furnace, therefor a bunch of dog hair got sucked in...so I have since purchased a new filter, and the smell has finally disappeared.

Thanks again everyone!
This web site and all you guys are GREAT!!!!

No Filter

If that much hair got into the furnace & you have A/C on that furnace, there is a fair chance a good part of the hair got past the heating surfaces & could be trapped on the A/C coil.

Or the underside of the secondary heat exchanger, just above the blower motor?
