My Compact 80E has stopped igniting. It goes through the fan sequence and the spark ignitors fire with DHW and CH demand OK but no flame.
I am assuming that the gas valve is not opening.
The PCB looks to have a section next to the transformer around the rectifier diodes where it has got hot.
The Valve is a Honeywell VX4105G but I cannot find any info on the net.
The PCB is a Honeywell 45.006.545-001 rev G same again I cannot find any info on the net
Without wanting to wreck a new PCB if the Gas valve is at fault I have the following questions.
1:- Does anyone have a spec sheet or wiring diagram for this valve/PCB or a full schematic for the boiler?
2:- Does anybody know what resistance values in ohms I should expect from the two solenoid coils on the valve ?
3:- Will the new PCB require the burner pressures setting up with the potentiometers on the PCB or should it just match the valve anyway?
Many Thanks
