Is it possible that snow build up in the exhaust pipe going through the roof could prevent the inducer motor from activating thereby preventing my heater from coming on?

**Bugeater** · 02-01-2011, 03:09 PM

That pipe should have a cap on it.

Check the flux capacitor and make sure the dilithium crystals haven't polarized.

Seriously... Seems like a convoluted solution for what's probably an easier problem (blown fuse, bad thermostat, etc.,.). Break out the multitester and start tracing backwards.

It does but unfortunately it's also got snow encompassing it. there's literally 1 foot of snow or more on top of the roof.

Well, I can tell you this much, if it's not getting adequate ventilation, you're better off with the furnace not running because carbon monoxide can back up into your house. I suppose there may be some type of sensor that shuts the furnace down in the event of a CO backup. I could probably give you a better answer in May after I've completed my gas heat course.

BE is correct. You'll need to clear the exhaust/intake before the sensor will allow the furnace to run. Although, I'd think it would extend beyond a foot over the roof.

If the furnace had been running you wouldn't have any build up of snow due to the heat from the exhaust, so I would say your problem is something else, turn the thermostat from auto to fan on to see if the blower motor comes on, if so your transformer is good and you have power to the furnace.

The pressure switch won't close if the flue is blocked.

Do you have a laptop? If so, take it up on the roof with you, and I'll walk you through what you need to do. If not, I'm happy to give you step by step instructions based on what you see up there. You'll need to come back down from the roof and report back to me what you see after each step, though.

Lol, yes I have a laptop. No I'm not going up there. Landlords here hopefully he'll fix it. Otherwise I've got to get creative, for it is not just me, but me two children as well.

Does the furnace come on at all?

no pilots lit, he's testing out the voltage right now, but I'm not really sure he knows what he's doing

That's why you need to get on the roof. We can have this fixed up in 3-4 hours, tops.

I work in HVAC, so let me know and i'll try and help you, is it a standing pilot or HSI, if you have a inducer motor that is the first thing that needs to come on.
