Hi All. I have just replaced the old pcb with new improved variety 5111603. It now goes through start up routine up to flashing orange/green, the fan starts, but no ignition occurs. After a minute or so the fan stops and the led goes to flashing red 3 times/sec, indicating an APS problem. I notice that from the instructions, no earth is required to the fan??. I also did not remove the fan. What do I need to do now?
