    I've got a basic Danfoss 103 timeswitch for controlling the heating/hot water. But recently I've noticed the red and blue tappets will end up not tripping the pre-selector wheel. Instead they'll reach the position for the current time and will remain there while the rest of the dial slips past, automatically rotating. So I end up with heating not coming on or not switching off. I then have to manually slide the tappets past the time position, flick the pre-selector wheel or set the switch to constant.

    Is there any way to tighten the tappets to ensure they travel round with the dial or should I just get a replacement timeswitch?

    U can fit a new one or if ur happy with the times an never want to alter them, a spot of super glue behind each one will stop them slipping til ur ready to fit new clock
