This was new in 2000. About 6 weeks ago the PCB failed which I changed and it started up OK. The PCB has once again failed and this time it has not only Blown The PCB but the main control fuse in the PCB and the spur point. I have checked the unit and ancillary equipment as far as I am able and I am unable to pick up a fault. Any ideas?
i had an experience similar to yours and it was a fault on the gas valve solonoid sticking and taking out all the fuses very expensive learning curve two boards and one gas valve
