Diagnosing heater problems

[UKjames]

So turned on my master temp125 today and it no heating

it’s definitely got power as can hear the fan cracking up. It’s got gas too as I could smell it after a while. The problem I’m guessing therefore is no spark. Does the heater do any fault codes or similar?

Thanks JamesW. I’ve had a poke around I think I need to get to the Fenwal unit and see what lights are on and check what’s live on it which I assume is in the steel box. Since there’s not much else to be seen when you take the side panel off

Having opened it up. Had a good look around but touched nothing, it seems to be working again !

my exhaust temp seems a touch high but not massively so (about 360)
