I do not have a manual for the T104M. How can I get one. Can't upload to my computer.

T104M is 208-277 timer mechanism that fits inside any Intermatic enclosure.
If voltage is not correct, then clock motor will not operate.
Since you did not say what voltage, I assume you have 240Volt pool pump.
Open following link to see the many ways to wire this timer:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html
It is possible that you have the Load and Line wires reversed.
Line wire come from circuit breaker, and Load wires go to pump.

If the T104M mechanism is part of a control panel with more than one timer, and/or a freeze control, then re-post question with more specific information.

Hi,
If you are flipping it off manually and it still won't shut off then the contacts are burnt together internally.
This means that you need to change this timer out....
If you switch it with the same timer you will not need to change the whole box... the old board will snap out and the new board will just snap in the old box, making the change out much more simple.

Sounds like 240Volt WG1573 clock motor has gone bad and needs replacement. But more checking is needed.

You posted under T2100-4R which is 60 amp Intermatic control panel with a single T104M 240Volt timer mechanism.
All Intermatic timer mechanisms can fit into same control center, so you can possibly have different timer mechanism inserted into the T2100-4R control center.
The control center can have up to 4 circuit breakers.
Instruction manual shows that timer can also have fireman's switch that is wired to pool heater and causes pool heater to turn off 20 minutes before pool pump turns off.

(1) First thing: If you have T104 mechanism, do a troubleshoot run-down to see if trippers, clock motor, or wiring are suspect:
http://waterheatertimer.org/How-to-troubleshoot-Intermatic-timer.html

(2) Next would be to check the circuit breakers for loose wires, burned connections, or the smell of burning or crackling sound that says breaker is loose on the busbar.

(3) Check for loose wiring on T104 and test circuit:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html
(a) Push the manual override lever to OFF position and test across terminals 1 and 2 and then across terminals 3 and 4 to make sure timer is turning off power to pump. Both tests should show 0 volts.
(b) Push manual override lever to to ON position and repeat test above. Both tests should show 240 volts.
If the test fails, then buy new T104M timer mechanism.

(4) If the T104 timer is turning off both lines in the 240Volt circuit, then pump cannot turn on since neither wire is Hot.
However if your T104 timer is actually a T101 timer or if timer has different wiring, where timer is turning off only 1 leg and not both legs of 240Volt circuit, then pump has one hot wire available and a short to ground could cause pump to turn on unexpectedly.

T21004R is Intermatic control center with T104M 240Volt mechanical timer mechanism.

Typically the T104M timer is not used to control a 2-speed pump, simply because the timer doesn't have NO NC terminals or programming capability.

Typically, if you are controlling a 2-speed pump, then a different mechanical timer is installed into the T21004R control center, OR the P1353 programmable timer is installed.
Open following links to identify P1353 and download instruction manual.
http://waterheatertimer.org/Intermatic-trippers-and-parts.html#P1353
http://waterheatertimer.org/images/P1353ME-2-speed-motor-500.jpg
IF you are programming P1353, read instruction manual and get along as far as you can, then add a comment saying where you are stuck. Use MODE 2 for 2-speed motor applications.

Thank you for including model number.
Intermatic catelog shows that T40404R is shipped with two T104M timer mechanisms.
However the mechanisms can be changed out for either T101M or T104M, and these timers can be wired many different ways so there is not 100% certainty unless you know or test voltages.

Here's the general difference
T101M is 120 Volt with 120Volt clock motor
T104M is 240 Volt with 240Volt clock motor

You can buy $20 clock motor and $3 trippers and fix the timer mechanism instead of replacing it.

1) Paragon is no longer making timers and parts except defrost timers.
4004-71M is not defrost timer.

2) Manual shows 4004-71M is DPST 40 amp 240Volt timer.
4000 series is 24 hour repeat timer

I solved this problem myself by Googling B&Q TE103 timer and downloading the B&Q instruction manual for the TE103 which I have printed and also saved to my computer so this does not happen again.

Consider NOT connecting your camera to your computer.


The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.


Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo cataloging program such as Picasa.
