Coleman 7900 Series

[Indians]

Can anyone tell me if there is an condensation tube on this furnace? If there is can you tell me were I might find it? The furnace is right outside our bedroom and when we wake up in the mornings and walk out to the hallway there is a smell. And it is right by the furnace. I can't even describe it. Tried changing the traps and that didn't work. I have checked for a dead mouse nothing...! The mobile home repair guy couldn't even figure it out. (But he didn't look that hard either...) Or any other suggestions?

Thanks

Sorry about that...thought I put the model # in....

Model # is 7975c856

What about the roof vent...could that be causing this?

Man I wish Mark was... oh lets see... 3 to 3 1/2 hours south...LOL

Do you mean the tube that comes from the drain pan underneath the a-coil? Yes, all furnaces need that tube. It generally runs straight down and should drain to the outside of the home (not underneath).

If its not draining, you might get a smell from the standing water (plus your probably getting water in your ductwork and maybe on the floors or in the belly).

A crawl underneath the home will tell you if the pipe is hanging below the belly (and hopefully not in the belly -- that would smell also).
