How old is this furnace. If it's an older one you might want to inspect the black drip leg assembly that the pvc exhaust pipe connects to. The seams tend to leak. There is a replacement kit to repair this with.

Probably a G26. I have a few where the foam gasket where the ventor attaches slowly leaks when they get old. Usually seals itself with mineral. Check the small black drain hose to the condensate trap. You should remove and flush that hose with hot water and clean the barbed fitting it attaches to yearly. Model # required. Post a pic of it also for more help.

They sometimes seal themselves with water mineral. If it is not leaking too bad I would leave it alone. Get the unit serviced properly by a Lennox tech. Flame sensor and the face of the burner it sits in front of should be cleaned or you will get low flame signal lockout. Hard to get that sensor out w/o breaking the porcelain if you don't know how.

The middle of the furnace inside the front panel, there is a box screwed on with insulation panels on the inside and what appears to be blower. This is where the clean air intake comes in the top. That compartment is full of water at least a couple inches deep. Last year I had the furnace guy come out and dry everything out and replaced the silver round bladder with holes. He had thought the only way water could get in that way was through the outside intake. I've checked it and it is very unlikely. Furnace worked great all last winter. We attempted to use it again yesterday and that box is again full of water! I'm drying it out as we speak. Do you have any suggestions to why this maybe happening Thanks Dean
