Hi,

My Prima F40 boiler is doing nothing when hot water and/or heating is turned on. The heating pump kicks in but there is no activity in the boiler at all. No fan, no pilot light, no relay activity, no ignition... Nothing.

Last september I replaced the PCB capacitors as I was getting the fan cycling issue and it hasn't missed a beat since.

Any suggestions on where to start with this would be much appreciated.

Cheers,
Jon.

Hi,

Thanks for the replies. I've fixed it :)

I was checking the fan voltage as per Mr K's suggestion and got nothing. I poked the connector and the board arked on the underside. I Removed the PCB and found that one of the PCB connector pins had come loose and broken the track. Resoldered it and and it's working again.

Thanks again for the replies.
