Gas furnace draining lots of water while the heat is on.? My gas furnace has been draining a lot of water from the condensation tube for several weeks of heating now. This wasn't a problem the past two winters. I do have a built in humidifier, but I've turned it off for several days and it didn't change the amount of water that is draining.

Repeated condensation of water in the pressure switch tube of my gas furnace! How to deal with this problem? A small amount of water collects in the pressure switch tube of my gas furnace every week which is located in the basement, enough not to close the pressure switch and therefore causing the furnace to click ON and OFF continuously.

Powering a gas furnace with a gasoline generator.? I am considering purchasing a 1200 watt (max) 10A generator. They are reasonably priced right now. I would think that it should power my furnace in case of a power outage. My furnace is 6 years old. It is a mid-efficiency type with a 4 position blower fan.

It seems to me if I disconnect it from the house wiring and divert it to the generator, everything should work including the blower fan, gas valve and thermostat.

It will not come on again unless I manually turn it on by turning the thermostat to off and then heat again.

Gas furnace blower motor rating? I have a 16-year old Trane XL80, single-stage gas furnace. I am replacing is with a new Trane XL90, dual-stage gas furnace. I'm rewiring my garage, and I'd like to put the garbage disposal (1/2 hp) on the same 15A circuit as the furnace, since I'm just powering the blower. Problem is I can't figure out what the blower draws. Does anyone have any ideas or any ballparks? I've asked Trane and gotten no response. I've asked the contractor who's going to install the new furnace, but he's decided to stop returning my phone calls (a common problem with Bay Area contractors). Thanks for any help. Answers to some questions. The existing circuits are - dedicated 15A for disposal (1/2 hp = 7A, roughly) - furnace shares 15A circuit with upstairs master bedroom and some general lighting Sq. footage, panel rating, main breaker rating, etc. are not relevant, since I'm not asking for total guidance. The reason I want to share these two appliances is that I've run out of space in my panels to bring the kitchen up to code, I don't want to rip out an entire panel to add 1/2 slot, although I may do that anyway, and I don't want to put motors on the same circuits as lighting. Per CA code, furnace blower should be on a dedicated circuit. Disposal must be. I'm cheating, because the probability of starting the disposal *and* having a 2-stage furnace kick into high (from a dead stop) at the exact same time is about as close to zero as it gets.
