    Boiler Keeps Clicking On and Off - PLEASE HELP

    Hi All

    Just wondering if anyone out there can help me at all.
    I have a Ravenheat LS100 boiler and we have recently just had the Air Pressure Switch replaced.
    Since then the boiler will fire up and everything heats as it should do - however once it reaches temperature and clicks off, it then starts back up straight away and then clicks back off again - it continues to fire up and click off until you turn the boiler off. :cry:

    Has anyone got any ideas what may be causing this?
    I would appreciate any help, ideas or suggestions

    Cheers x

      Hi Sunbeam

      Thanks for that - but unfortunately it did not work

      We changed that part and still no different.
      So far we have changed the PCB, the Air Pressure Switch and now the central heating thermister and the boiler still does the same

      Does anyone have anymore ideas - it's driving me crazy :x

      Thanks

      Jackie
