I inspected a home the other day with a Bryant Furnace forced air Model # 394GAW036100. Now I know it’s a 100,00 BTU but according to Preston’s guide It could be anything from a 1982 to 1989. My real question is after turning up the thermostat I waited for the fan to kick on. NO fan, I went to the basement and found the unit trying to light. After about 1-2 minutes the furnace lighted and after about 3-4 minutes the fan came on. My experience is that the fan should come on first before the furnace lights the burners off. Am I wrong? My Bryant is a 1990 125,000 and the fan comes on first. I figured the fan has to come on first to move any excess gases and so the heat exchangers don’t over heat waiting for the fan to come on. Any help would be great, I’ve already explained that the unit was operating incorrectly, and they agreed, but if I’m wrong I want to call the agent ASAP to tell her I messed up. Thx
