Question about Intermatic T104R 208-277Volt 40-amp Timer Switch-Double Pole / Single Throw
Does the manual override work?
If manual override does not work, then the timer is probably worn out.
Buy new T-104 (not T-101 or T-103 because these have 120V motor)
No need to replace box >>> new T-104 mechanism snaps out and fits old box
If override works then the tripper pin could be worn out.
How it works is this: The tripper pin come into contact with a metal lever, and the clock motor pushes the wheel until the tripper clicks the metal lever. The manual override is connected to same metal lever.
Tripper is softer metal and wears out before lever
Grainger sells Intermatic trippers:
