The Off tripper does not switch timer clock off

Are there any diagrams available to show precisely where - and how - to place the tripper pins? (the tripper pins are new) The "off" pin does not seem to make contact with anything.

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.

Which way do the pins need to be positioned on a manual timer for it to be on, ie is it up or down for `on`

You posted under GE 15004 timer.
Push trippers down and then rotate tripper around dial to desired on or off time.
Release tripper and it tripper locks upward in place.

Other timers have segments and pins that are located around timer dial
The position for ON-OFF varies by brand and model number.

I suggest you turn lamp ON and make sure bulb is good, plug lamp into timer, set a few pins one direction or other, plug timer into wall. Manually rotate timer dial clockwise, and watch lamp turn ON-OFF to know how to set pins.

Also move the slide switch one direction and then other direction to see how override switch operates.
After checking operation, set pins exactly how you want, and then rotate dial clockwise until current time lines up with pointer located on inner dial.
Dial rotates with passing time and pins push small lever that opens and closes circuit.

Where are the "never-lose pins"

Woods 59204 manual says pins, and I think the timer has tabs or segments instead.
These are located on the rotating part of dial.
Look at pictures on following link to see 4 basic pin-tab-segment layouts that are used to turn these timers on and off: It's likely that your timer will be one of these.
Some timers have pins that click in and out
Some have segments that pull up
Some have segments that pull out
Some have segments that push down
Add a comment any time.

The phrase 'never-lose' means the pin-tab-segment is permanently attached to the timer dial.
Older timers, and many box timers have loose pins or trippers that you attach to the timer dial ... and of course people lose these trippers and are constantly searching for their model number of tripper which is not available. And some of these older timers were expensive. For example the older style malibu power packs have trippers, but when the tripper wears out, there are no replacements and power packs are expensive.

If timer has been working fine up until now, you probably need a new tripper pin

If lever is worn out, then you need new timer.
You can but a T-101 and swap insides without changing box
The T-103 will also work because it has a 120V clock motor
The T-104 is a 240V timer and will not work
You can buy the replacement timer mechanism and swap out

When wiring new timer, put wires back the same as old timer
For T101 and T-103 wiring schematic, see following link

If I understand correctly, you have Intermatic dial-type timer.
The dial or clock is turning but the timer does not turn ON and OFF.

Here's what to do.
1) Click the manual override to see if Load (lights, fan, motor) comes on.
The manual override is your best diagnostic tool.
If the manual override does not click back and forth very well, then timer is probably bad.
You can buy a new Intermatic and snap the new timer into old box without changing boxes.

2) If the manual override does not turn on the Load, then the electricity to Load is suspect.
a) There could be loose wire inside box or loose wire at Load
b) The breaker to Load could be tripped if the Load operates on different breaker than timer. For example some timers run on a 120V breaker, but the Load is a 240V pool pump.
c) Load is not working. For example the light is burned out.

2) If the manual override works fine and Load goes on-and-off, then you can have 4 possible problems.
a) The tripper pins are not placed on the timer dial
b) Tripper pins are worn down and you need new trippers
c) If this is a new installation, then wiring can be reversed, so check wiring

If you need Intermatic tripper pins:
If you have a T-100 series timer, then the following page shows wiring for those timers

Please write back after you narrow down the suspects.
We'll get your timer running.

Installed new T104 timer 3 mos. ago. Bldg. owner says the dial "hangs up" on pins--has to use manual on/off. Wiring is correct.

1) The clock motor might be bad if trippers hang up on pins
2) The timer might be exposed to dirt dust and moisture, in which case the T-104R raintight might be better
3) The tripper pins rotate around until they contact the tripper lever >> the pins push the lever >> new Intermatic timers have a bit of white grease on the lever where trippers contact
4) Test the manual override to see if it clicks back and forth crisp and clean >> the trippers click the manual override back and forth, so if override is sluggish, then timer might be bad >>> buy new timer and swap out insides without changing box
5) Sit and watch the timer and see if trippers hang up or they skip over the tripper lever> you might need new trippers. This seems odd with a new Intermatic timer.
6) The building electricity may have gone off and the timer is not set on current time and the bldg owner doesn't know how the timer works.

The timer is used on an Electric Point of Use 2.5 water heater. Currently I get hot water only about two hours in the evening. Before it was --on demand. I opened the timer box and one of the timer box"...

No overcharges here Ms bernarda

If I understand correctly you have Intermatic timer with a yellow dial
You have the Intermatic timer hooked to a small 2-1/2 gallon point-of-use water heater
Your point-of-use water heater is working fine
The timer turns on the water heater once a day instead of twice a day

And it seems like one of the tripper pins has fallen off the yellow dial
The tripper pin is missing and you can't find it or put it back.
You can turn off the electricity and poke around the bottom of the timer box and see if tripper pin can be pulled out using tweezers
Do you know Grainger sells Intermatic tripper pins for $1.67 plus shipping?

New 220 timer put in ,wont turn on.Vsiual chek working and its keeping time,switches look good but woont kick on?

I wish I knew the model number.
maybe the wiring is wrong, but different model numbers have different wiring.

I wrote a page on each the T-104 and T-1906 240V timers:
It shows the wiring for 2 common Intermatic timers

Now let's troubleshoot a bit:
You say the dial is rotating around.
And the dial has tripper pins in place.
What about the manual override? Does the manual override turn lights on and off?
If manual override does not turn on the Load, then your wiring is suspect.
If manual override works, then your wiring could still be wrong by one wire.

Check your tripper pins.
Are they attached and set exactly right?
Are you using both ON trippers and OFF trippers?
1565897.jpgThe OFF tripper pushes a lever. The lever is connected to Manual override. Click manual override to see if timer can turn Load ON-and-OFF

Up-vote if this information helped. Thanks for the feedback.

The off tripper pin is not turning off my timer. Why?

Does the manual override work?
If manual override does not work, then the timer is probably worn out.
Buy new T-104 (not T-101 or T-103 because these have 120V motor)
No need to replace box >>> new T-104 mechanism snaps out and fits old box

If override works then the tripper pin could be worn out.

How it works is this: The tripper pin come into contact with a metal lever, and the clock motor pushes the wheel until the tripper clicks the metal lever. The manual override is connected to same metal lever.
Tripper is softer metal and wears out before lever
