Mend Micron 50FF Boiler Heating Pcb

HOW CAN I FIX MY BOILER MICRON 50FF?

Hi
My boiler doesnt always fire up.
It fires up when the timer switches on but does not fire up again for a second time.
When you tap the PCB the 2 orange lights come on and the fan and pump run but no flames.
Help and Regards
Chris

I have this exact boiler myself.....assuming all the external controls are ok they are pretty simple.

It s either the Fan...you say thats ok

or

The PCB itself....PCBs and Fans are common to go on a lot of boilers.
