The furnace can leak if it is in Heat if it is a 90% furnace. The tube comes off below the inducer draft motor. If your unit is in AC mode and it is leaking then it is due to condensation. The most common cause is a plugged condensation line wich is usually PVC (white) you can flush it from the furnace area through the pipe with compressed air.

Has the water been leaking when the air conditioner is in operation?

My furnace is leaking water, this just started what could it be and is this something my husband can repair u think? What are some at home troubleshooting suggestions to track the leakage. Right now we only see it at the bottom of the furnace and its leaking down on my ceiling

You forgot, the inducer motor also creates a pull on the gas to pull it through the heat exchange

I’m in Ottawa as well. What company did the install?Sometimes new furnaces have defective parts. I’ve installed a new Keeprite once and 3 weeks later the board was defective.Although I was there the very next day

Wow I’m sitting in a cold house with a 2 week old york furnace.
Ottawa Canada. – 11 c
I will never buy another york product
I have been calling my heating contractor no answer, thats a funny thing from a company who claims 24 hour service.
I hate being lied to and ripped off.

i was unlucky to find a diagram of this furnace on the internet. However, i do know that this is an older Lennox. Besides the noise, you should have the heatexchanger inspected by a professional. Your gas company is normally qualified to do so but sometimes has had a good training course. You could have a routine maintenance done for a small fee. Just make sure they do visual heatexchanger inspections and that they provide a carbonmonoxide test. They will also tell you about the noise.

good vid. I have a probkem with my furnace that this video didnt cover though. The unit works fine but it makes a loud chugging noise almost like a train when it kicks in. I thought it was the belt but it looks fine, ive also read that it may need to be lubricated or bearings need to be replaced. If anyone has any ideas, post and let me know.

I just had a bad snow storm that dumped 17.5 inches of snow in the area and the pipes/chimney were plugged on the roof for the furnace from the snow so i had to wait for the snow to melt and it worked, I was getting the LED status error code 31 because of the plugged pipe for the inducer I believe.

I need help my ignitor is not getting voltage to it,I checked the 3 terminals on the pressure switch with the thermostat calling for heat :1st I disconnected the rubber pressure hose from the fan-end & just left it hanging, I had voltage on 2 of the 3 leads on the pressure switch, nothing on the 3rd lead.2nd test, I reconnected the end of the rubber tube to its place (where it should be)I got the exact same result: voltage on 2 of the 3 leads on the pressure switch…nothing on the 3rd lead.
