Ravenheat LS80(T) is not working, no fan noises, no flames. I change it PCB still not working, althought is a second hand PCB. Still has the Same problems as the red light shown. But when i first fit in the second hand PCB, the fan and flames did WORK! but only last for 7 seconds. and then i tried few more times, same, the fan and flames only last for 7seconds. And afterward the fan and flames not working at all!!!, and show the same light as the original PCB. (red light means overheat)

if it lite for seven seconds then it might be the electrodes not sensing the flame and its gone to lock out, dont throw any more parts at it, get an rgi .

etheir you have not put pcb in correctly
or as picasso said get a rgi as problems in the combustion chamber or gas vavle

Doesn't this one has a seperate ignition PCB on the gas valve?

If so then that might be at fault.

However, a gas engineer would always be the best bet.
