I tried running my furnace for the first time this year after I had a central air system installed. When I turned on the furnace, I got the blower to turn on, but the furnace did not ignite. I looked at the status on the unit and it says that it is calling for cooling and not heat. Are there any obvious easy causes for this I could try before having to call someone?
