poty boiler fails to ignite,fan starts,aps proves,spark at burner,checked over heat stat ok,18v at gas valve,should be 210v+

So I here you say its the dreaded PCB?,
well I have changed the PCB for the 5111603 TWICE thinking the first was faulty,
Can I be that unlucky to have TWO faulty PCBs

What's your GV resistances? Should be 1400 & 2800.

SHort on GV used to take th eold board with it sometimes. Wonder if the new one does too

 

[bobw1956]

yes ChrisR i,ve heard about the gas valve taken the older PCBs out.

I checked the voltage at the GV on black /red wires before I attached it to the GV.at the same time as spark

Should the resistance on the GV be 4000?

and who paid for the second pcb which you blew up ?

CORGIS ... always good for a laugh

... as long as you don't foot the bill

raden

another prick,if you can,t be constructive **** off

 

[geoff@cetltd]

up yours

if you can''t properly diagnose a fault, keep away from boilers - clueless CORGIs are not only expensive, they're dangerous

... and you sound clueless to me - I only asked who paid for your incompetence
