baxi 105e flame and safety thermostat neons flashing

[paulcroad]

hi, i've had various work done on my baxi 105e but it still wasn't working as it should be so the engineer said changing the pcb board was the last solution so i've done this as i didn't have the funds for him to do it but after doing this the above neons are now flashing so i'm guessing the thermostat might need changing ANY IDEAS plz

Did you mark and swap connectors correctly. More so the earth wires if it the new model of board. If the earths are not connected it will throw up a fault. Only mentioning this as I had a customer do a PCB DIY. Then got me out only to find earth not connected.

hi, yes followed the other board step by step, new board was set out slightly different tho, is the earth a yellow and green wire

Sounds like other faults are causing this - and they are gas related so need to be checked by a gas engineer.
