SOURCE: Fan switch will not make (limit switch).
If the snap switch is not located close enough to the plenum, this can be problem. The other option would be to cover the switch area with a metal shield or liatherm paper (fire rtardant paper).
SOURCE: Carrier air conditioner problem
My Carrier unit did the same thing. It was low on refrigerant (Puron in my unit). I am worried I have a leak somewhere. Hopefully, it is not in the coil. The service call wasn't cheap either. Puron runs around $10-15 a pound and mine took several pounds to replenish.
SOURCE: Furnace and Air conditioner run at the same time

What are you fanning??? the fire?
Do you have a circulator that circulates when the water is up? Many controls have a AUX connection ... wire the AUX to your fan --- alaternatively, wire directly fron your circulator connection to the fan.
I hope I understood your question ...
Let me know what happens.

SOURCE: Code #33 on Bryant 355MAV 90i Furnace
'Limit or flame rollout switch is open'. In my case, the flame rollout switch had tripped due to an overheating? I had to push the button between the wire leads to reset the switch. Then when I turned the power back on, the furnace started up like normal.
Why did the switch overheat and trip? My current theory is that there was a rubber grommet around a pipe near the switch that had slid down and was no longer sealing the furnace?
