Magazines have issues. What you have there isn't an "issue," it's a failure.

It could be a mechanical failure such as the cam that operates the internal mechanical switch. Or the switch itself may have failed.

You can try tearing it down, but you may find that no replacement parts are available for it. The easy answer is replacement. I've been using one similar to this for close to 20 years and it's still humming along. If you need multiple on-off events per day, you can get extra trippers here.

Usual disclaimer: the links are for information and I don't mean them to be endorsements.

Toss it out and get a standard time clock as the previous post mentioned. They're inexpensive and easy to use. The Intermatic time clocks have been around for a long time.

No Extra trippers required - the photo shows the plastic On-Off tabs on the wheel... This permits up to nearly 50 independent On-Off events already.

Stax, YES, EXTRA TRIPPERS REQUIRED, if he replaces that GE with an Intermatic. Good grief.

"Good grief." You really do go after people that post any help to one of your ill advised posts!

(BTW Some Intermatic, just like the shown GE, use plastic pegs and not the example you chose to show.)

Don't continue to be a moron!

Good grief.

How about Tork timers? How do they compare to Intermatic?

I don't know anything about Tork timers, but i have two 30 year old mechanical Intermatics just like the one David linked, and they are still working as good as new.

The Intermatic timers last a long time. Easy to install and easy to set up timer. Plus, if the clock motor ever fails, you can remove and replace it without having to change the entire enclosure. There's tabs that release the clock motor.

Thanks! How difficult is it going to be to wire a new timer from a different manufacturer? I can do some wiring (like replace light switches) but don't have a lot of knowledge with complex wiring. Here are some pictures of what I currently have.

You have a powered timer that is actuating one set of relay contacts. Very basic circuit. The TIMER terminals need a black and white wire from a power source to power the timer. The black wire coming into the box from the right to the TIMER terminal is the hot leg and the corresponding white wire is the neutral wire. Both are needed to power the timer. The NO and COM terminals are a single set of relay contacts that turns something on in the outside world. The black wire from the TIMER terminal jumping over to the COMmon terminal takes the hot leg power over to the relay COMmon terminal. Then, the black wire from the NO (Normally Open contact takes switched power to the outside world. When you disconnect things to install the new timer, make sure to shut the circuit breaker off and mark the two black wires coming into the box so you know which goes where. Hope this helps.
