Old (80%) Furnace and "light codes"


Hi

The furnace is:
Payne PG8UAA04209

Theres a red LED at the base (in the main fan chamber), theres a window to see this LED from outside. While the main fan is on, this thing is flashing, what i thought was SOS. All other times its just on, unless the furnace isnt doing anything then its off.

--- ... --- ... --- ... ---

However on reading the front of the furnace this seems to be a "fualt code" of 33, i am going to be removing this soon, however can someone please tell what has gone wrong on this unit.

It all seems to be working fine, however doesnt give alot of heat out so i bet this code has something to do with the burners, or maybe the fan itself, not sure.

Some input would be good here.

typically lack of air flow, the main limit has tripped on high temperature. Check all vents open, clean filter, clean evaporator coil.

Thanks, FIXED

Was a carpet stuck to the aircon evaporator, pulled this off (by hand, was easier than getting a huge vac hose in there), put everything back together and restarted the unit, it then run without the burner turning off until the house was up to temp.
