Carrier Furnace codes

What is the code for the failure your experiencing ? Look at the red flashing indicator light on the Circuit Board in the blower compartment .. count the number of flashes then refer to the sticker on/in the furnace for the correct code and respective likely problem. On certain model Carrier furnaces., there have been specific problems associated with THAT model ; ie : Faulty circuit boards / faulty limit switches / faulty pressure switches, etc...

GIve us the model number of the furnace and the code number that flashes for you.

I can't find a model number but the error code is 14 - Ignition Lockout. It will work sometimes and not work other times. It's been blowing cold air since 6pm tonight.
