Lennox Pulse won't keep running
I'm sorry I don't have as much info as I should, but here it goes. I have a natural gas Lennox Pulse system from 1989 (model number is at home, I'm at work) and it works fine and blows nice warm air when I first turn the thermostat to heat. The problem is that it only runs for 1 cycle and then shuts off. If I turn it off then turn it back on, it will run for 1 more cycle. Doing this I had the house in the 70's yesterday when it was 30 degrees outside so I know the heater itself works. I also replaced the thermostat since I thought that could be the problem (and I wanted a new one anyway.) This might also help, last summer the a/c unit in it decided to leak water everywhere and then stopped blowing cold air. Could this be residual damage or be related to the a/c problem?
