    Thanks. This timer has metal trips and it starts and stops at times when it is not even close to the trip levers. The trip levers work as they should, when they should. On a warm day I will pull the cover off, clean it, etc.

Some more things to check,

check to see if the pump has power on it, when it is not running.

make sure all ur connections are good.

if u have no power when it is supposed to be on the timer itself could have a short internally

Replace the trip levers, I dont think your timer turns off and on without trip levers? Unless your outdoor fixtures have photo cells on them or wired to them! Are they coming on at night and shutting off at Daylight, if so they are connected to a photocell or have internal photocells which means you don't need the timer unless you want to control different on off times.

What position is lever on intermatic pool timer t104p3 for timer to work?


Lever automatically moves back and forth as trippers pass.
Move lever to ON position, move to the right.
If timer dial is not rotating, then check wiring, or replace clock motor:
If timer worked before and stopped working, but dial still rotates, the trippers are worn down, replace trippers:

The "little gray box"


You need 2 ON trippers and 2 OFF trippers.
Part number 156T1976A sold at WW Grainger etc.

1) Copy following links for WH40 little grey box Intermatic timer operation and resources:
http://waterheatertimer.org/pdf/How-to-operate-and-set-T104-timer.pdf
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T104

2) WH40 timer is identical to T104, same replacement parts, same operation, same wiring options, except the grey box timer has override lever that sticks out of box. Both WH40 and T104 have override levers, the WH40 override can be moved without opening box door.
This allows you to use the WH40 as ordinary on-off switch if the trippers are removed from dial.

Ti04 clock rotates and new trippers but doesn't turn on


You probably have T104 timer.
Clock rotates so power to timer motor is good. This means 240Volt breaker is good.
Use override lever and see if Load (light, fan, motor) turns on and off. If override does not turn Load on-off, then bypass timer and see if load works. Move wires from terminal 2 to terminal 1, and terminals 4 to terminal 3.
Did you order correct trippers?

You installed new 240Volt T104 Intermatic timer.
Cause of problem is not determined, so read information below and then add a comment with further observations.

According to question:
Timer is wired correctly.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html
The on-and-off trippers are installed on dial, but do NOT click the override lever back and forth.
Both ON and OFF trippers are on the dial.
And the timer is NEW and not used, and trippers are NEW and not used.
And the dial rotates and keeps good time, making 1 full rotation each 24 hours.
And the manual override lever works and turns load (pool pump) on-and-off.

Open following link to view photo image of OFF tripper coming in contact with manual override lever.
Trippers are soft metal, and made to wear down. When tripper gets old, it will slide over the lever instead of move the lever.
http://waterheatertimer.org/images/WH-lever-005-500.jpg
Open following link to read how to set timer, and see close-up images of timer with trippers on dial, and tripper order number for replacement trippers.

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:
http://waterheatertimer.org/Paragon-timers-and-manuals.html#4000

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.

When setting my timers should the manual switch be left in the on or off position?


Either position is fine.
The override is not permanent ON or OFF since it moves back and forth when trippers pass.
The trippers push a lever back and forth that opens and closes electrical circuit.
When the lever moves back and forth, it also clicks the override back and forth with audible sound.
If the timer is ON, you can move the override to OFF.
When the next ON tripper rotates around, it will move the override back to ON.
So the override just temporarily overrides the timer function.

I am trying to learn how to set up the T104 timer etc. I just moved in and there is no manual how to set timer.


Here are two links that will be handy to keep on file:
http://waterheatertimer.org/How-to-troubleshoot-Intermatic-timer.html
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html

T104 is 240Volt timer.
When you open the door, there should be piece of translucent plastic covering the wiring.
As long as plastic cover is in place, it is safe to touch visible timer parts.
If you have a child who might stick something into the timer, then lock timer door.
As a general rule with electrical devices, do not stand on bare ground or wet surface or lean into or touch anything metal while working on timer. Put down dry boards. Same with your circuit breaker panel.

The T104 yellow dial rotates just like a clock.
The dial has ON and OFF trippers attached to outer edge of dial.
As these trippers rotate around they move on-off lever that turns the pool pump or Load on and off.
ON tripper moves lever one direction, and OFF tripper moves same lever other direction.
The manual override lever clicks back and forth with audible sound each time tripper moves on-off lever.

Move manual override back and forth and it will turn Load on and off.
Override should snap crisp and clean.

To set timer, lift and rotate dial until current time lines up with stationary silver pointer.
Stationary silver pointer is pointed at 6:00.

Power is good going into the timer but the timer is not running. I am wondering if there is a fuse that needs to be changed or a reset switch? The timer has been replaced in the last year.


If I understand correctly, you have T-104 240V timer.
Timer was running fine before, and recently stopped working.
If this is not your timer, add a comment.

1) Click manual override back and forth to see if Load turns on-off.
If Load does not turn on-off, then check power at Load.
Timer has 5 terminals A 1 2 3 4
Check terminals 2 and 4 for 240Volts when Load is ON

2) Check terminals 1 and 3 for 240Volts to make sure timer has full 240V and breaker is not tripped OFF on one leg. If timer has 120V, it appears to have voltage, but clock will not rotate and Load will not turn on-off. Check breaker for 240V across both screws.

3) Is dial rotating?
If dial is not rotating or is stuck in place, replace 208-277V clock motor.
http://www.grainger.com/Grainger/timer-accessories/timers/electrical/ecatalog/N-8hi
http://www.grainger.com/Grainger/INTERMATIC-Time-Clock-Motor-1PNK2?Pid=search

4) If dial is rotating, but trippers don't flip on-off lever, then trippers may be worn down. Buy new trippers.

5) How to wire T104 timer
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html

How timer works
:
Clock motor rotates dial.
ON-OFF trippers on dial contact lever.
ON tripper pushes lever one direction.
OFF tripper pushes lever other direction.
Lever moves electrical contacts together, or pulls contacts apart.
When lever moves on-off, manual override lever also snaps back and forth with audible clicking sound.
