How long does this timer last or what is the warranty

Asked by Steen September 22, 2020

Warranty per Home Depot. These are Industrial Times and used by factories through out the USA. Very robust with nil maintenance. The only caveat is owner carelessness: if you don't tighten the time indicator set screws sufficiently, they will slide & the start/stop times will not be correct.

The gears inside stopped turning after one year.

I had to replace the dial mechanism. The on/off would manually work but the timer part stopped. Just replace and you’ll be happy.

If the timer tripper is close to turning the timer on or off, it feels locked up because it is engaged with the switch. If you lift the yellow dial and move the tripper away from the switch it will be easy to operate the switch on or off. You will need to reset the yellow dial to proper time after you manually work the switch.. Hope that helps.

Where can I order more trippers in order to create more frequency for on and off such as 10 mins off and 30 mins on?

You should probably have GFI protection on the circui as I assume this is for a submerged pump. You should consult an electrician for the proper sized GFI.

These are approximate as this was wall mounted and there were obstructions between me and the timer, but they are close. H = 9.5" W = 6.5" D = 3.5"

can I replace a t101 with a t104 ?

Hello, this is Matt from Intermatic Technical Services. Thank You for the inquiry about the T101 series timer. The T101 is a 120 volt single pole timer. The T104 is a 208-277 volt double pole timer. So if you are going to use a different voltage you could switch them out, otherwise stick with the T101. If you have any further questions please call our Tech Support Team at 815-675-7000. Thank You for choosing Intermatic!

I did have that issue but my issue was due to the trippers not being placed on and tightened enough. Once I got the trippers on just right and tightened them. It’s been working fine. I hope this helps.

It was the perfect way to automatically turn on and off the outside building restaurant sign at Wild Elk Den in Chandler Arizona. According to the manufacturer of the LED sign if it is left on all the time it voids the 10 yr warranty. Even thou it does not consume much electricity it is best to have it turn off to maintain the warranty in effect. We set it to turn off at 3am and back on at 6pm, therefore only running 9 hours per day. It makes everybody happy.

On Off lever is sticking but still works on timer. Would have given it a 5 * if lever not sticking. Too much trouble to for me to take it back to Home Depot for replacement. Decided to live with it since it works on the on off timer pins in place.

This is the second one of these timers I have purchased. The first lasted for 28 years but finally stopped working, so I replaced it with another. It controls a sodium vapor light in the parking lot of my office building. The timer is in the garage and protected from the weather.
