My intermatic timer won't trip back on

I have just replaced my old timer with a new 240 volt intermatic 24 hr timer. When I set the timer the clock will run and the off tripper will trip the clock off but the clock will stop running.When I reset the time and set the pump on off with 1/2 hour to the on tripper,the tripper will get to the lever but it won't trip it on,like it oesn't have enough force.

    What i meant it's that is 240 out of my panel but it splits to 2 120 volts loads at the timer. I also used the correct off and on trippers. My timer runs my pool pump and its a 207 volt 277 volts timer.

I don't think the timer runs on 240 volts does it? You can switch 240, but the timer uses 120 volts to run. You might check the connections and timer clock rating more closely. Also, the 'off' & 'on' trippers are different, make sure you use the right one.

    I am having a bit of trouble understanding your issue but I think your problem is this: You're trying to switch 240 or 208 volts to the pool pump right? You need a 'double pole' timer. It can switch both the hot wires to the pump. Or you can switch one of the hot wires to the pump and the other hot just goes straight to the pump. Wire nut straight through the timer. Make sense?

120 Volt timer.
When timer is ON, test across terminals 2 and 3 for 120 Volt
If 2 and 3 show 120 volt, then timer is delivering power on schedule. Look for loose connections. Loose wire nuts.
If 2 and 3 do not show 120 Volt, then timer has failed.
Suggest buy T101 as replacement for durability and generic replacement parts.

My Intermatic T101 has power going to it and the clock works normally. But when the clock trips the switching lever to ON or I manually turn it to on, it does not put out power. Is there any sort of fuse...

There is no fuse inside the T101.
If timer clock motor is working correctly, then 120Volt circuit is fine up to the timer.
Unknown if this is new installation , or old installation that stopped working.
Wiring might be bad, such that line and load wires are reversed.
Or light bulb might be bad.

Sounds like the clock leads are on the wrong posts, or at least the hot one is. If if was moved to the load side then manually starting the timer will also power up the clock motor. As soon as the clock trips the off timer, the pump and the clock motor are both off. Examine the clock leads to the wiring diagram inside the clock box cover to ensure they are connected correctly. I bet you'll find one of the wires is misplaced.

Hi, I have few quick questions regarding the Intermatic HB114C 240 Volt, I would appreciate if you can answer my questions 1. Does this unit have Internal Built in Clock to set up the Clock or does...

HB114C timer likely will not work in India.
Contact Intermatic:
Plug type is different than found in India.
India power generation is 50 Hz, so timer might not keep time even with plug adapter.
US power grid is 60Hz, so US-sold products are 60Hz.
Some timers are both 50Hz and 60Hz, but spec sheet usually shows that information.
HB114C spec sheet does not show Hz.

HB114C is analog appliance timer with clock motor that rotates dial once every 24 hours.
The timer does not have a countdown feature.
Trippers are placed on dial.
As dial rotates, trippers move small switch that opens and closes circuit to load.
Current time is set by manually rotating clock dial until current time lines up with arrow located on inner dial.
After power failure, current time must be reset.
There is no way to install a battery back-up inside the timer.

The timer that you have is a 120 volt timer. You are only breaking 1 leg of electricity which means in the off postion you still have 120 volts going to the heater. Also the clock will not function because you do not have a neutral going to the A terminal. You will need to replace time clock with a 240 volt clock T 104

I set my T104R3 on and off clips to desired times and turned the timer on. At set time the timer went off, but the clock stops and does not continue and turn on at the desired time.

The T104 timer is miswired when it does things like that. The 240 volt clock motor is internally connected at the factory to terminals 1 and 3. That means that one of the incoming (line) 240 volt wires (pick one) _must_ be connected to terminal #1 and the other _must_ be connected to terminal #3.

The outgoing (load) 240 volt wires are connected to terminals 2 and 4.

The Intermatic wiring diagrams leave a lot to be desired. I wrote the following tip to help clarify intermatic T103 and T104 timer wiring, I hope it helps:

How do you wire a model GMXST-1-240-M Intermatic timer

There are many ways to wire the Intermatic GMXST-1-240-M timer. If it is not wired correctly you can permanently damage the timer.

For "regular" use, if all you want to do is turn a 240 volt load ON and OFF with the 7-day timer, and you are _very_ sure that you have a 240 volt timer (they can be 120 volt or 240 volt), here is how to wire it:

LINE connections:
The first incoming LINE (L1) 240 volt wire (pick one) is connected to terminal #1. A jumper (same wire size) is then installed from terminal #1 to terminal #3 [(COM) or (Common)].

The other incoming LINE (L2) 240 volt wire is connected to terminal #2.

LOAD connections:
The first outgoing (LOAD) 240 volt wire (pick one) is connected to terminal #2 _also_.

The other outgoing (LOAD) 240 volt wire is connected to terminal #4 [(NO) or (Normally Open)].

Again, while this is still just a basic timer there are at least 10 different ways to wire it depending on what kind of equipment is used, how one wants to control the equipment (using the Normally Open or Normally Closed contacts) or (HI or LOW speed for a 2 speed fan), the clock voltages (120v or 240v), and the load voltages (24 volt to 240 volt).

If you are not sure how to wire this timer after reading this post, I highly recommend posting back with very specific information or calling a _qualified_ electrician, as mis-wiring this timer can permanently damage the timer, connected equipment, and/or personnel (that means you).

Here is the wiring diagram:

Intermatic model T1O4R stopped working. time dial does not move

Can you turn the load ON and OFF with the manual switch? If not, the circuit breaker supplying the timer has probably tripped. Turn the breaker OFF, then back ON. Sometimes a breaker will trip, but it looks like it's still ON.
If you are getting 240 volts at the timer from the breaker, and if you can also manually turn the clock dial, then the timer motor is bad.
