Hi,

I really hope someone can help me. I have a Bryant 340MAV.

I cannot seem to get the furnace to stop flashing code 33. It doesn't go to 13 either, which I find strange. I also tried bypassing the limit switch, temporarily, just to see if this was the problem. Still getting 33. Also tried completely removing the air filter, again temporarily, to see if that would help, no luck.

I have tried turning it off for a couple of hours, but 33 starts flashing almost immediately.

Thank you!
