SOURCE: My intermatic timer won't trip back on

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.

SOURCE: tripper makes contact but fails to fully trip switch:

These often have wear problems. Look for wear on the trip clips.

SOURCE: Timer will not shut off

T40004R 100 amp control panel has one 240Volt T104M timer mechanism.

1) If this is new installation then timer is probably wired wrong.

2) If timer worked before and stopped working, and timer dial is rotating and keeping good time, sounds like you need set of 156T1978A trippers.

3) Open following link for timer troubleshoot and trippers:

I have unscrewed my tier pointer by mistake to coincide with the current time on my T21004R timer. Now I cannot get into start and turn off where my on and off indicators are set. How do I correct thi

T21004R is single 240Volt T104M mechanism inside a 60 amp control panel.
The T100 series timer has stationary pointer that is supposed to be straight downward. Move pointer into downward position and apply bit of super glue to hold in place, or just remember where it should point.
Copy following links for instructions how to set and use the T104 timer.

The T104 timer is rated for 40 amps, and is usually repairable, uses WG1573 replacement clock motor, and 156T1978A trippers. Trippers are made of softer metal and are designed to wear out before wearing down timer mechanism.

Intermatic T104 timer wont turn pump on,despite being tripped

If override lever snaps back and forth crisp, and turns pump ON-OFF, then timer switch is good.
Try installing new trippers. The trippers wear down and start to slip over the trip lever.
If pump does not turn on-off with override, look for loose wires at breaker or pump.

What is name of srew on timer dial that trip switch .

It's called a tripper.
Question posted under Paragon 4000 series timer that uses X2772 tripper.
Paragon is no longer making that timer or tripper.

If different timer is needed, use Intermatic crossover to match timer number:

Apparently, the spring under the timer dial on my 4001 timer has been broken and the timer will no longer trip the trippers. Can this be fixed? It is a nearly-new unit and I like it.

Open following link for Paragon resources:

Individual parts are not sold except for X2772 tripper.
Move the manual override lever back and forth and see if load turns on-off.
Watch if on-and-off trippers are moving override lever back and forth, to see if problem is a worn tripper instead of broken spring.

Replacement 4001-00 timers are sold, even though Paragon is no longer making timers except defrost timers.
Replacement timer is Intermatic T101

GE Indoor Outdoor Timer # 15306 the clock is working and the when the time for it to go on it goes on but when the time comes for it to shut off it does not trip the off switch. I then have to shut it down...

1) If analog dial keeps time, I can only guess that OFF tripper is not in position correctly, or tripper is worn or defective, or that manual override lever is defective. Trippers are made of softer metal so they wear down before other parts of timer.
2) Buy Tork P47 trippers to replace GE 15306 trippers

3) Open following link for GE timer resources:

4) 15306 is heavy-duty indoor-outdoor version of Tork 1800 series or 7200 series 120Volt analog timer that is sold online and at Home Depot under GE brand name.

5) You can buy new timer at Home Depot and return defective one in new package.

6) The on and off trippers are attached to the analog dial.
Dial rotates as time passes.
Trippers make physical contact with the manual override lever. The ON tripper pushes lever one direction and the OFF tripper moves lever other direction.
The override lever rotates a cam located on back of timer that opens and closes electrical contacts.

I get lights when I turn the switch to on but as the timer advances, it doesn't trip and turn the timer on

You posted under Intermatic T101 timer.
Add a comment if timer is different.
1) If this is new timer installation, it sounds like black wires on terminals 1 and 2 are reversed.
Other cause could be the ON-OFF trippers not positioned on timer dial

2) If this is old timer that worked before, then tripper pins could be worn down.

My paragon timer4001-ov runs but will not trip on/ off trippers if this cannot be repaired what would be a good replacement for 120 volt supply

I don't see the 4001-ov in the Paragon spec sheet

To test the general condition of your Paragon timer, use the manual override.
If the manual override works perfectly, then you may need new tripper pins.
The Paragon 4000 series uses X2772 tripper pin.
Google search Paragon X2772 tripper turns up prices of $9 for a pair of trippers

A simple 120V replacement timer is the Intermatic T-101
For outdoor, use the T-101R 'R' for raintight

Lowes usually has the T-101 on the store shelf and they sell the T-101R online

The Off tripper does not switch timer clock off

The pins trip a switch behind the dial, you can't see them. Don't worry they will trip the switch and turn and off. Just slide them on the edge of the time dial where you want to go on and off and tighten.
