its the gas valve circuit on the pcb apparently.
the red led is on constant with the orange flashing twice every 5 seconds or so.
red = lock out i assume
has anyone had luck with this fault?
i'm having the same problem (with the service light - orange -flashing twice). So far i've replaced the gas valve, the pcb and the temp sensor with no luck (one at a time, not all at once).
I'm running out of ideas.
