There might be a couple things that are easy to overlook.
Press the button to see if lights come on >>> if light do not turn on with manual override, then light might be burned out or circuit breaker tripped. Sometimes a breaker is tripped but you can't tell by looking at it
1) The timer is used on incandescent bulbs only. I don't know why, but it says no
2) Is the red indicator light ON?
For programs to work, timer has to be in automatic mode and the red indicator light will be ON
The Switch Timer can be used in two modes. manual & automatic
To switch between modes, quickly press the dial twice:
AUTOMATIC MODE: The Switch Timer will turn your lights ON or OFF according to programmed settings. The RED indicator light stays ON when in Automatic Mode.
MANUAL MODE: Programmed settings are inactive, and
the Switch Timer will only turn the light ON or OFF when
you push on the dial.
RED indicator light stays OFF when in Manual mode.
3) setting current time> lets look at the red indicator light while doing this
Move switch lever to OFF-Clear
Move lever to ON >>> red indicator is flashing
Rotate dial to nearest current time (if it's 7:20 pm, rotate dial to 7:30pm)
Press the dial once to set current time > red indicator light goes off
Do not accidentally press dial or it will set the wrong time....ok we know that
4) overlapping programs/
Make a chart of the times you want to program with ON and OFF plus am & pm
Check your chart for overlapping times that tell the timer to do more than one thing
Rotate dial clockwise to the first ON time >> pay attention to am & pm
Press button and first ON time is set
Rotate dial clockwise to the first OFF time >> watch the am and pm
Press button and first OFF time is set
You can have 48 on-off times >>> which seems a lot for a 24 hour repeat timer
5) try the timer with one program
6) If timer still doesn't work, put switch back in and see if lights turn on that way >>> it could be a loose wire suddenly cropped up
Last step >>> timer is no good, you need another one. We tried.
Testimonial: "Thank you, I followed your instructions and the timer is working properly."
