Let's do a checklist:
> The battery has to be installed before you program timer, so that is good.
> Press Mode button and it over-rides current program ... so mode button acts as the manual override. Try manual override and see if Load comes on.
> The manual override is the real test. Plug something else into timer and use the manual override to see if timer is able to complete a circuit.
> If manual override works then your programming is suspect. (see more below)
> If manual override does not work then electric circuit is off, or timer is bad.
> After using manual override, press clock to return to current time
> Make sure Mode is not set to random
> The clock must be keeping correct time, or you would have mentioned it
> Check that the electrical plug has power.
> Check that the Load (light, fan) operates fine without the timer.

Programming problems:
> The timer program calls for ON time and OFF time for each program. If the ON time was skipped, then timer will not turn ON.
> If there is a conflict in programming, the timer will not operate as expected. For example program1 says ON at 7 and OFF at 8, but program2 says the opposite.
> Another example is when the AMs and PMs are mixed. For example you want ON at 7am TU and OFF at 7PM TU. But the timer was set for ON at 7am and Off at 7am.
> When programming, write out a schedule so there are no conflicts.
> The ON and OFF functions should follow the same days. For example ON is set for 7am TU but Off is set for ALL week.
