how to fix timer on Saunier Duval boiler?
The timer on my SD boiler doesn't go around as it should. I can hear it ticking when I put my ear close and if I turn it to the correct time manually the central heating will kick in. Saunier want £100 for a replacement. I am tempted to take it apart and look at it. Anyone got any advice?
