I have a Meridian gas furnace and the blower is running constantly. The heat is working. The diagnostic code is blinking twice and says "Primary Limit Circuit Open".
Blower running constantly. Burner limit open - not primary limit
I checked the filter and all the vents and then shut it off and restarted. Same thing.
I may have read the improper diagnostic code.... i think it's actually the burner limit - not the primary limit.
