I am not going to copy the whole manual for you because the manual has images that explain the steps.
But I will post the manual, and then you add a comment saying exactly where you are stuck.
I will respond to help you over that trouble spot, and then you add another comment, and then I will respond again until your timer is going.

If the free answer above is not correct for you, take advantage of fixya phone service.
You pay fixya expert to read steps from the manual while you program the timer.

Do I set the GE timer # 15089 to Auto on or Auto off for it to be activated. I had it on Auto on however the light stayed on all the time.

I don't have repair for defective timer.
Open following link to identify timer and download manual:

Timer should be set to Auto ON for timer programs to run.
Auto OFF is temporary override, and timer resumes schedule at next set point.
ON is always ON
OFF is always OFF

If timer is not operating as expected:
Test outlet for correct polarity and electrical problems using cheap circuit analyzer from hardware store.
Timer programs can have conflicts. Make schedule before setting timer so there are no overlaps that cause timer not to function as expected.
Current time has not been set. Set current time including current day.
Set button has been accidentally pushed, and a number or CTD appear in display.
Timer needs to be reset to clear conflicting programming or error. Push reset button with paperclip and try programming again.
Timer is not able to handle intended load. All timers work for incandescent bulb. Connect timer to incandescent lamp and see if problem continues.
Timer is defective. Buy another timer from Home Depot and return defect in new package.

Iam trying to set the GE MODEL15089 and I seem unable to do so

I test timers. Some arrive defective.
GE makes a good timer, and sometimes the instructions are hard to understand.
1) When I have a problem with timer instructions, which is frequently, I write out the instructions which seems to help me understand.
2) Sometimes you need to reset the timer and then it recovers and works fine afterward.

Open link below to identify timer and download manual.
I am looking at the manual, and can see it has illustrations that show how the display should appear at each step.

1) The manual is too long for space allowed free answers, so I can't write out the instructions.

2) However, I suggest you reset the timer and then go through instructions carefully.

3) When you reach a specific point in manual that is confusing, simply add a comment to this post and I'll answer.
