Customer Question

Good morning Rick
I have a Halstead Hero 60 (in pretty good condition). Over a period of time I have experienced the boiler lighting for about 5 seconds and then going out. last week I changed the analogue PCB for a digital one, replacing the harness and thermistor at the same time. Great, the boiler lights and we have really hot water and radiators but..... After a variable period 15 minutes, 60 minutes0 the boiler stops and the H4 green light on the PCB stays on (the H5 lockout light does not come on). Re-setting doesn't cure the problem but after a lot of twidding eventually does. Incidentally the boiler is really hot. I have checked the APS, and venturi and the pipes seem clear. The PCB was given to me as "an opened box off the shelf" to try. Although the boiler now lights do you think that the replacement PCB is faulty or could the problem be something else?
Regards John
