Diagnostic Code: Primary Limit Circuit Open
 
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".

How can I fix it? Thanks for the help.

Clean your air filter/make sure all vents are clean and 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.
