Yes it is a timer issue, and yes the whole timer will need to be replaced. If you are handy it is not very hard. You can order the timer from marcone.com with your model # and it will show you a parts breakdown so you can see hoe to replace it easier

Yes, you can buy the timer and not replace all of the lights.
Intermatic timers can power a variety of appliances and lights.

yes, timer, it has a tooth chipped and can not advance to next cycle. That is why when you turn knob just slightly it restarts.

press "menu" button, scroll down to "special features" and press "ok" button, scroll down to "reset lamp timer" and press "ok" button, you will notice the "no" change to "yes" and press "ok" button, you will notice "yes" change to "no", this will reset the lamp timer
