Randi, first thing to do is to change the battery and see if the timer will allow you to reprogram it. Sometimes these timers fail, as certain models have a known history of failing fairly often.

NoOp, means non operating within the Intermatic line of electronic timers, so in order to see if the unit has failed or is just malfunctioning, due to a weak battery, remove the existing battery and install a fresh, new one.

You can remove the existing battery by flipping down the front switch panel and removing the battery tray with either your fingernail or a small flat bladed screwdriver. As your timer is showing the NoOp, you don't have to worry about losing your programmed on/off cycles, so you can take your time. Normally, if you're changing the battery, you get about 30 seconds to do this with some models of Intermatic timers, or you'll lose the settings. The newer models store the program regardless of how long it takes to change the battery.

Once you've replaced the battery, press the Reset button on the timer and allow it to refresh. If the NoOp is gone, just reprogram the timer with your on/off cycles and days and you're back in action. If the timer doesn't clear, you'll likely need to replace it, as it could be damaged and will not be able to be programmed again.

Usually, changing the battery and resetting the timer works about 60% of the time for me, as I've installed thousands of the various Intermatic timers in customer's homes over the years.

Hope you find this Very Helpful and best regards!

I connected out door X mas lights to the Utilitech 3 outlet photocell timer. the lights went on at dusk, as they were supposed to. But they started blinking on and off. what is worng?


Unfortunately someone went to great lengths to copy/paste the wrong instruction guide to this solution. Like me, the OP has a 3 outlet PHOTOCELL timer, not a 2 outlet DIGITAL timer. Photocell determines dusk/daylight/etc. We also have the same issue. Wondering if has to be connected directly to outlet. Ours worked fine when plugged into outlet. When we moved it after Xmas to run year-round lights, plugged into extension cord and problems began. No response to date on emails sent to mfg.

No op on window and does not turn lights on or off


1) I read somewhere that folks have fixed the 'no op' problem by removing screws on back of timer and adding bit of oil to the gear.
I don't know if this works, or if repair lasts.
When that information was posted, several people said it was a good solution.

2) Otherwise you might try changing the battery.

3) Reset timer:
ST01C timer: Hold down ON-OFF and push in reset button.
Keep holding down ON-OFF until INIT shows, and then release and 12:00 should display.
EJ500 timer: Same instructions except hold down Next/ON/OFF

Also take advantage of fixya phone service.
For a price, expert speaks with you over phone while you work on timer or any do-it-yourself project.
Fixya is always less expensive than a service call.
