Potterton netaheat not firing

[finchy01]

Hi chaps. I have a customer with an old netaheat that not firing. When there's a demand fan starts, pilot light but no main burner. It was cycling recently so I have replaced the pcb as I know they are notorious for that and all was fine For a few weeks, now I have a recall X for this. Im guessing it might be the gas valve but wanted to know if any of you have any advice What else to check when I go back?

Thanks in advance.

Are you gsr, pm one of the mods with your number. We can't give gas advise on open forum. (aparantly)

Thanks Leo and Phil. Actually no need as just got back. Genuine recall as there was a loose connection on pcb. Sorted and only out the house 45 minutes. That's what we like! I willget in touch with the mods though to get on the 'inside'!!
