Propane 2 zone heat
 
Here is my problem, Our upstairs heat works fine, the downstairs heat doesn't work. The thermostat will click on, and you can hear the gas furnace (if that is what it is called) engage, but only for a few seconds, then shuts off when normally the fan would turn on. The fan works fine, if we put it in the on position it will blow cold air, but no heat. It is usually in the auto position, and only stopped working this morning. This is a new house, and we are used to an oil burner for our heat, and always figured out how to fix it. This is new to us, and we have no clue about how it works.

If it's a new home you should still be under warranty, call the builder for service.

I have zoned heating, it is the best thing in the world. Guessing you have a fuse burnt out in the control panel for the zones

Have it checked out, it could be several things with what you have said.

What I meant by New house, is it is new to us. We have been here a little over a year, the house is 6 years old. There is no warrantee, any repairs will be out of pocket. My husband is pretty handy with everything we have had to do to any of our houses. When it was the oil burner, we looked up, troubleshooted, and always figured it out. This is our first experience with this heater, and really would like to try to figure it out before we hire someone. Anyone have any ideas on what to look at first?

Ok, I got the heat to work, but only if the fan is in the on position. I don't know what anything is called on the thermostat or the unit, but there is a thin copper wire running around the front of the mercury switch on the thermostat, with a silver pointer that can move around it, which had some kind of corrosion or something on it, I moved it around a little to remove the white stuff, and tried all the positions on the thermostat. When I put the heat on with the fan on, the heat comes on. Blows out nice and hot, thank goodness, it was pretty chilly on the first floor. The problem now is that the fan won't turn on when it is in the auto position. The same thing happens, you can hear the gas firing up, and when the fan should engage, the gas just shuts off, no heat, no fan. If I turn the fan to the on position, then turn the heat to on, it works fine. I really want this to work properly. I keep turning on and off the heat when it warms up and cools off. I don't want to have the fan running all the time. Any help would really be appreciated.

Sorry to double post, but I also found out after looking through the attic, the crawlspace, and outside, we have 2 heater units. One in the attic for the upstairs, and one outside which is apparently the air conditioner and the heat for the first floor. The heat upstairs works fine because it is a separate unit. (Don't really check things out until there is trouble) So the heat being fine upstairs has nothing to do with the downstairs heat, I guess that doesn't make it 2 zone heat does it. Still All help and suggestions would be great!

Call a pro, you need a fan limit switch.
