The code for the LED on the Circuit board should be on the lower panel where it shows the schematic for the wireing and what-not. Three flashes I think points to the pressure switch that is connected by a hose and two yellow wires. It makes sure the blower (black plastic looks like a turbo) is running, these fail regularly and can be replaced for about 15-20 bucks without having to call in a tech. good luck!!

pressure hose
The gray pressure hose that is attach to the pressure switch was loose on mine. After I tighten the hose the pilot came on and the red led light was a steady red.
