Question about Electric Intermatic 7 Day Digital Timer 500 Watt 120 Volt Heavy Duty
When I changed to DST this morning the timer would not shut out the light. This is a wall mounted timer and controls a ceiling light fixture.
That knob should just pull straight off. Check to make sure there isn't a tiny set screw on the side, but otherwise you can pull it off and remove the cover plate.

Do you mean Intermatic E104C box-type timer? Intermatic does not make E140C
Manual says "refer to programming instructions on time switch door"
Manual says timer has 8 events per 24-hour day ... 4 'on' events and 4 'off' events. Normal operations, selectors are set to AUTO and RUN.
Using sketchy info from manual about programming:
Set sliders to MANUAL & TIME/SET
Press EVENT for event 1 ... set hour and minute using HOUR & MIN buttons ... this will be 'on' time
Press EVENT for event 2 ... set hour and minute ... this will be 'off' time
Set all 8 events ... 4 'on' and 4 'off'
Move sliders to AUTO & RUN for timer operation

1) If timer dial does not rotate, then clock motor is not getting electricity, or clock motor is bad.
-Make sure time dial is seated correctly. Pull it off firmly and then push in firmly.
-Check circuit breaker is not tripped.
-Test across terminals 1 and 2 on timer for 240Volts.
-Test terminal 1 to ground and then test terminal 2 to ground to make sure each hot wire from breaker has power.
-If circuit breaker is tripped on one leg, the timer can appear to have power, but is only receiving 120V and not the full 240V, so the time dial will not rotate.
-Look for signs of high heat and burning.
-Check that no insulation, and only copper wire are under the screw-down terminal plate.
-Make sure that same gauge wire is used, and that stranded wire and solid copper wire are not under same screw-down terminal plate. The stranded wire will come loose.
2) WH21 is rated for 25 amps and has 1 year limited warranty:
If label on side of water heater shows rating of 5500 watts, then divide by 240Volts = 22.91 amps.
4500 watts = 18.75
3) Replacement clock motor is not shown for WH21 timer.
