The thermostat is not the old round style, it is programmable. The wheel I mentioned is on the left side and allows overriding the set temp, among other functions. Batteries are ok, I suspect air is the problem. The furnace sat all summer and now that cooler weather has arrived, this problem has surfaced. It's sporadic. Most of the time it starts up fine. This morning I heard the induction motor star, run for about 5 seconds, shut down, then immediately start up again. I get the proper red flashes, fast red when calling for heart, slow red when not. Assuming it is air in the line how do I bleed it?

I should add that this is a programmable thermostat purchased 3 years ago at Home Depot.

The override was done by rotating the temperature adjusting wheel on the thermostat.

I have a Trane 60,000 BTU updraft furnace, about three years old. Yesterday when the induction fan started up in response to the thermostat, it ran for about 5 seconds, then shut down. It has continued this pattern, although if I override the set temp on the thermostat and wait about a minute, it fires up normally and continues through the complete heating cycle. Could it be the thermostat?

I have a Trane XR95 natural gas up flow furnace, 60,000BTU. In the last couple of days the primary blower starts up when the thermostat calls for heat, but shuts down after running only about 5 seconds, before the burners kick in. I have read all of the posts and haven't seen this particular problem.
