Hi I am looking for some help working on a Carrier model 59zav!

Am I too guess at what your problem is exactly?

Am I too guess at what your problem is exactly?

You must be new,, one of the main tools needed is a crystal ball,, I could loan you mine but is in the repair shop,, :),:)

I have one of my own but it's out in the truck.

Sorry! Yes I am new to the field and I am trying to find out why this unit is not blowing heat. It lights and the fan blows heat but after a short period it shuts off and the pilot goes out. Is it possible that the vents need a good cleaning or is it something more? Diagnostic code flashes 2 3.
