    I've been doing some work in an (empty) rental property. I told the owners that I would leave the heating ticking over to try and prevent any problems.

    Yesterday I had the heating running for an hour or so, with the Programmer 'On', however when I switched the Programmer to 'Auto' the boiler stopped and will not re-start. The boiler On LED is lit but the fan does not start (even if I put the programmer back to 'On')

    I left it off over night and went back today. Exactly the same thing happened, although I switched the Programmer from 'On' to 'Auto' after a minute. The boiler is definately receiving a call for heat.

    The only other thing I noticed is that when I returned today the pump appeared to be running, despite the programmer being off.

    Any obvious causes? As the last one to touch the system I feel responsible for at least trying to identify the problem.


    Thanks, Jon.

    Here's the solution in case anyone else is stuck.

    Boiler needed a new APS. The old one was sticking open, and the boiler wouldn't relight. Leaving the boiler off overnight was allowing the switch to unseize.

    Sounds reasonable to me.The APS has to prove position B4 the ignition process starts.
