## Questions & Answers

**Q: Is there another RELIABLE 24 hour timer that is good and easy to program. This one is junk!**
A: Of course there is, the GE 15802.  It turns my outdoor post lamp on and off perfectly.  Easy to read and program.   Piece of cake to program, and if there is an outage, it only looses whatever time the power is out, only needing to spin around to the correct time.  Available at Amazon for $11.75 at http://www.amazon.com/Jasco-Products-Company-Switch-15082/dp/B0035WY6CS/ref=sr_1_fkmr1_1?s=hi&ie=UTF8&qid=1388525463&sr=1-1-fkmr1&keywords=ge+timer+15082However, this one is one of the smallest and I was desperate to get it to fit into an existing painted box.  One thing I learned it failed after working for a few months was to turn to turn it off for 24 hours.   Still difficult to set or correct.

**Q: Will this work with CFL bulbs?**
A: We have this timer on our front porch.  Our lights on the front porch are CFL bulbs.  The first timer we installed ended up not working very good, but we had another one.  My husband installed it almost a year ago and it's working just fine.  We set the time we want the light to come on and the time for the lights to turn out.  Can't complain.

**Q: Does it need a different front plate**
A: No. The front plate on the timer goes over your existing wall plate.

**Q: I loost the time indcator after I pull the dail off where can I geta replacement**
A: Trash it because it's junk.  Instead, I went to Target and bought a different type that's made by GE that lets me set the number of hours I want the light to be on.  By trial and error, I learned that the ones which claim to turn themselves off at dawn usually don't work, especially on cloudy mornings.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Simple to program, works well
  

*by M***F on Reviewed in the United States on April 23, 2010*

I have been using two of these for close to 20 years.  One controls the light over our front door, the other the light on our detached garage.  One recently failed so I replaced it.  You can't find these at Home Depot, etc. so I was happy to find in at Amazon.Pros-Fits over the switch plate.  The front door light switch is one of four with a brass cover plate, so this unit easily adapts.  In the garage, the plate has a switch and an outlet - again the unit adapts.  So it's perfect for an older house.  Easy to install.Once you get the hang of it - easy to program.  If there is a power outage or the bulb(s) burn out, you have to re-program.  I used to keep the instructions at hand but know I know the drill.Compared to a digital unit, it's easy to program.Makes your house look lived in and saves power by turning the light off.Cons-A little on the ugly side, but not an eyesore.Does not work with compact fluorescent bulbs - incandescent only!

    Porch light timer
  

*by C***Y on Reviewed in the United States on April 20, 2013*

The newer digital timers will not work with the older wiring in our home. The mechanical timer was easy to install, easy to program and works as expected.  Our porch light goes on at dusk and off at dawn whether we are home or away.  The big question is how long it will last.  The first timer we had in this location lasted for many years.  Unfortunately, subsequent timers have not worked as well or lasted as long.  Only time will tell.Just over a year after installing this timer it stopped working. Overpriced for a short-lived product.

    Everything a timer is supposed to be!!
  

*by B***R on Reviewed in the United States on December 1, 2010*

Call me an old fuddy-duddy, but I'm sick of everything having to be digital!  I have manual timers on a couple of other switches in the house, so when I wanted one more, I went to two different home centers and a hardware store - nothing available except digital.  So I bought a digital GE one, took me forever to program it, then after about 3 months - like so many things digital - it died.I finally found this one on Amazon, and it's perfect.  It installed easily, and contrary to what some other reviewers said, I found the programming to be a snap.  The instructions were clear and easy to follow, and I set my start and stop times with no problem.  And that's exactly what I wanted - a timer that turns my porch light on and off - not one that knows the phase of the moon in Tibet and the train schedules in Siberia and whatever else manufacturers try and cram into digital products these days.Fast shipping, a good price, easy to install, easy to program, and works exactly like it's supposed to.  What more can you ask from a product?  Definitely five stars, and thank you Amazon for continuing to carry products like these when the retailers have all gone digital (are you listening Home Depot, Lowes, and Ace?)
