    Central Heating won't come on, but boiler works OK

    Right - problem isolated. Great tips/advice seco services! The motor isn't moving far enough to push the micro switch - and it sounds weaker than maybe it used to (I can't really remember). If I manually close the micro switch the boiler fires up. Do I make the assumption that the...
