20 Most Recent Intermatic 10 Amp Mechanical Indoor Timer Questions & Answers

This answer is a little misleading. ALL the pins between the time you want the lamp on to the time you want it off must be pushed down. In other words, the lamp will light only when the timer reaches a pin that has been pushed down. You could have the timer turn a lamp on and off and on and off and on and off, etcetera, if you had one pin down, the next up, the next down, etcetera. It's a good visual indication of what the lamp will do: pin(s) DOWN = lamp ON; pin(s) UP = lamp OFF.

Try resetting timer. Small round hole located just below the display... use paper clip and push and hold for 5 seconds... then reprogram timer If functionality is not restored, then replace timer. http://waterheatertimer.org/Intermatic-ET-series-timers-and-manuals.html#ET100 Gene Water Heater Timers Save Money If you need further help, I’m available over the phone at https://www.6ya.com/expert/gene_9f0ef4df2f9897e7

Rotate dial until current time lines up with arrowhead located on inner dial.
The segments located around edge of dial are pushed down or raised to set on-off times.
Push segments down for times you want timer ON

Override switch on top of timer.
For programs to operate, move switch to Timer ON

Plug lamp into timer.
Turn lamp ON
Plug timer into wall

Check the voltage to the spin motor or its continuity.
If OK then try to move the mechanics two three turns.

without the model number it is difficult to advise you on the setting proceedure .. here is a site that you can find the manual and read how to set the timer. ..

http://www.google.com/#hl=en&source=hp&q=intermatic+timer+manual&rlz=1R2ACEW_en&aq=f&aqi=g1&aql=&oq=&gs_rfai=&fp=8760bbf0a0f5f1ee

you set the arrow to the correct time. You then pull the green and red plastic pointers up and out of the device and push them back in at the times you want it to activate. I believe green is off and red on but I may be backwards on this. Some come with multiple on and off pins you would simply remove these or pull them up so they do not trigger the timer

Reading the broad description I would have said "yes if you can identify the input and output of each separate circuit. However the description says

• Selector switch to determine input voltage between 120-277 VAC

So you have to select the voltage on it. It appears there are also various model differences to the 1725 series designated by a letter at the end after the '5'. ET1725C, ET1725CR Ask their support https://www.intermatic.com/Product/ET1725C?setcontextlanguagecode=en https://www.google.com/search?q=Intermatic+1725+switch+220+and+110+simultaneously ..

There is troubleshooting in the link plus contact direct to Intermatic. You can get parts and yes an electrician would probably look at it for you if you don't wish to try yourself. Make sure the centre knob screw is tight and make sure the On/Off tappets are tight.. https://www.google.com/search?q=Intermatic+timer+repair

I would suggest you get a qualified electrician to look at this. If you've not touched it in 20 years the mechanism inside may need checking for age related faults. Even when not used some parts can cause issues as they get old.
