Whose idea was it to change all those parts?
We dont advise on gas or combustion issues on this forum.
The advice would be to get a competent gas reg engineer to diagnose the fault.
In fact I could have found and fixed the fault for less that half the cost of all those parts!

if Very good chance the new board is faulty ,
Some of The myson apollo`s used to use a different board from the thorn apollo which was basically the same boiler and every other part was the same and a lot of people thought they used the same board to. Possibly you have got a board from an apollo.
Threw a myson board out just last week as i havent fitted one in 20 years the boards used to say myson on them

Electrode cable was broken, board was only £35 , and the previous engineer did say that the air sensor switch was the problem. All this has been replaced, boiler fan comes on there is power at all the inlets and outlets apart from the solenoids. Power at board connection for them but no power at spade connectors at solenoids. Surely this would not stop it sparking, there is power at ht connection at board also. ?

Ps the electrode cable was broken, and the old aps was faulty anyway and needed replaced. Ignition board was purchased at very cheap price at £35 pounds. So I have a spare just incase. Labour costs nil. gas engineer put pipe on wrong connection, suspect broke the cable also, then said could not get parts. Then tried to sell us a new boiler. Guess who?
