Lennox furnace

[Tim Klassen]

I bought my house in 2006 It was built in 1955 and the Lennox furnace in the house was installed at that time. Two years ago the hamster wheel went out on the furnace and there was no replacement, they just didn't make 'em anymore so I had to replace this 60-year-old furnace. Well maybe nothing runs like a Trane, but I doubt it'll give me and whoever comes after me 60 years.

Hi i'm working on a Lennox furnace and this is happening.... When I shut off the power to the unit and turn it back on the furnace fires right up, once the thermostat has reached it's set temp. the furnace shuts down and locks out immediately. What would cause this to happen? once the main power to furnace is reset the furnace fires right up until it reaches set temp.... Any suggestions would be much appreciated!
