Glow worm protherm 40/50 ci behaving weird

[Steve weightman]

Hi folks a letting agency boiler I've been asked to diagnose and repair the first visit the fans on but no sparking first thought was aps and the orange light on the pcb was also telling me so it's the pcb with the two fuse. So new aps fitted now I have the orange light to say aps proved and now sparking but now no fan working why this is with sparking this I can't work out as we all now it's fan on aps proved then sparking ..advice appreciated

Is a Protherm basically like an Ultimate?

If Fan isn't running but trying to spark either you've put the APS back incorrectly or a faulty board?

Mods can we move this to the GSR engineer section?

Yeah just like the ultimate I can only imagine the wiring on the aps that's giving continuity some how through the aps and sparking. Can't get the grey honeywell aps no more but now the white plastic type with no c/no/nc on it just 123 I'm sure I've wired it right but I could be wrong

I've got a bunch of them in my garage at home! I'd check the APS wiring, never had one try fire before without Fan running.

If i can find out what the 1 2 3 terminals are on the new aps that would help
