Oil smell from furnace (when fan is on but flame out, I think)

Dec 10, 2006 12 Replies

We've had an oil smell coming through our vents for about a year. Our local heating service company has come out twice and found nothing. Neither the smoke detectors nor the carbon monoxide detector protest and we haven't had any apparent health effets. Yesterday I realized that the smell only comes through only after the temperature exceeds the setting on the thermostat and contines for a while until the fan stops blowing. I don't know if it works this way but I'm guessing that the fan keeps going for a little while after the flame is out. If so, that seems to be when the oil smell occurs.



I would appreciate your advice/thoughts.



You need a new furnace. Try a heat pump. Get a new thermostat. Bubba

My first question ...would be??? Do you have an oil furnace?

Make and model...some oil furnaces have problems and characteristics

I will say it again I am not HVAC person However from mechanical point view it seems that you are having some oil residue that it needs to be burn out, you also may have draft problem check your smoke stock make sure you are not getting down flow on shut down, does your chimney is adjusted for proper draft, any chance that your furnace creating vacuum in your basement, does your ignition system shut off before the oil, defective pump shut-off valve, the air entrapped in nozzle due to restriction in supply line oil expansion in the nozzle line assy. due to radiated heat at shut down, make sure that you have makeup air at location of furnace, your chimney temperature perhaps some what low for the draft require or needed, Good luck from Dido

Who'd a thunk?

and you think Oil, could be doing that?

smoke stock? Is he stocking cigars now?

Yes, he had the bricks rotated for proper draft just the other day.

Yeah, they all do that. I think this brand furnace is a "Hoover".

Yeah, they all do that too.

That would be called an "oil pump"

Im going to need that one in English please.

He just ordered a box of that yesterday

You have a draft versus temperature chart now? This one I gotta see Bubba

Thanks all for the replies. Furnace repair is over my head, for sure. I've decided to call a different service company (and hand them a summary of your responses.) I'll report back here for your interest on what they say/find/do. Wish me luck. I don't want to have to buy a new furnace.
