i've got a myson Apollo 30si boiler late eighties.
Goes through the ignition sequence fan comes on and pilot ignites.
it continues to spark repeatedly and main burner wont light.
There are two solenoids on gas valve, i've got 240volts on pilot one and nothing on main burner solenoid.
Air pressure switch has got continuity at all connections, so all points to the board.
I can still get parts for this but very pricey, so would like to be spot on.
Any ideas or similar experiences ?
