There are a lot of problems that can affect timer operation.
Call 1-800-824-3005

We can start guessing at causes, and then you try some things, and add a comment with what you've done so the possibilities are narrowed down.
This could be a wiring problem, timer problem, load capacity problems, circuit problem, possibly a noise interference problem.
I would check load requirements and wiring first.

1) Load:
Manual says: DO NOT INSTALL TO CONTROL A RECEPTACLE, FLOURESCENT LIGHTING, A MOTOR, OR A TRANSFORMER OPERATED APPLIANCE.
Some recessed lighting can have transformers.

Try timer in another room on a different load.

2) For single-pole operation, the black and blue wires are used, and yellow wire is capped off.

Try reversing blue and black wires.
Make sure yellow wire is capped off.

3) For 3-way operation, the timer replace one of the 3-way switches.
The other 3-way switch remains in the circuit, but wiring has to be changed on the remaining 3-way.

Leviton 6124 timer instructions:
Timer comes with plastic protector over display >> remove protector to see display.
Large button is manual override.
After timer is wired, push override to make sure Load turns ON and OFF.

Timer has 3 small buttons located below manual override used for programming
Display is divided into 24-hours with am times on left and pm on right.
24 Hour day is divided into 1/2 Hour segments
Each 1/2 hour must be set for ON or OFF

Start by pushing left-side event-cursor-advance-button and it scrolls down each 1/2 Hour.
Once you arrive at 1/2 hour > make decision if you want timer ON or OFF for that half hour.

Press event-set-reset-button in center to set ON-OFF for that 1/2 hour.

Press center event-set-reset-button and solid black rectangle fills in for that half hour.
Solid black rectangle means timer ON for that 1/2 Hour.

Once solid square is selected, press event-cursor-advance-button and cursor advances again and starts filling in black rectangles for each 1/2 Hour period.
Keep filling in black rectangles for all times you want timer ON.

When you reach 1/2 Hour period you want timer OFF, then press center event-set-reset-button so that no black rectangle is visible for that 1/2 hour.
No black rectangle means timer is OFF for that half hour.

To set current time, use right-side time-advance-button.
Press and hold time-advance and time cursor advances down through the am and then pm hours.
Stop cursor at current time, and timer is ready.
