Hello I have an older T103 Intermatic which controlls outside lights. It is no longer turning on lights and is making an unusual clicking noise. Can it be repaired or should I install a new one? Chris [email protected] 707-546-4910

the motor is defective, it is available on line price about $20-25.

if it won't trip it, the on pin is not lining up right and u need to take it off and put it making sure it is right. if that's not it u got a bad timer

Intermatic T103 is mechanical timer with moving gears.
Timer makes audible sound when tripper clicks on-off, but it should not make constant noise unless gears are causing noise.
Turn off power and spray WD-40 on gears and see if problem continues.
WD-40 vapor is extremely flammable hydrocarbon when sprayed, and should not be sprayed on live electric circuits.
If problem continues, turn off power, pull mechanism out and spray WD-40 on plastic gears of clock motor.
Open following links for illustrations of clock motor and removing mechanism.

T-103 is 120Volt timer that can be used to control 120Volt and/or 240Volt loads, for example pools and spas and outdoor lights.
Look at the yellow dial and see if it has trippers attached to dial.
If no trippers are on the dial, then the timer function is off.
Next look at dial and see if it rotates as time passes.
If dial does not rotate, then either the clock motor is bad or electricity to timer is off or timer is not connected to power.
Test across terminals A and 1 for 120Volts will tell if timer is getting power.
Last, move manual override back and forth and see if anything turns on and off.

As you probably know, Paragon is no longer making timers and parts except defrost timers.
4003-00 is not a defrost timer
4003-00 is DPST 120Volt timer 24-hour mechanical timer

Intermatic cross reference shows that T-103 is replacement for 4003-00

T-103 has 120Volt clock motor and can control 1 or 2 - 120V loads or 1 - 240Volt load

T-103 has 120V clock motor with 5 terminals A 1 2 3 4
Tork 1101 has 120V clock motor with 4 terminals L 1 X 2

T103 is DPST and can control one-or-two 120Volt loads, or one-or-two 240Volt loads.
Tork 1101 is SPST can control one 120Volt load

Common ground between these timers one 120 Volt load
Changeover for one 120 Volt load:
White wires T103 terminal A go to Tork terminal X
Black wire T103 terminal 1 goes Tork terminals L and 1 (there is brass connector plate that connects L and 1 - if connector is missing, jumper between L and 1)
Black wire on T103 terminal 2 goes Tork terminal 2

If Load requirement is greater than T1101, Grainger sells T103 clock motor for $16

How to wire T103

T1101 wiring manual

T103 Intermatic timer has 120Volt clock motor and can control 120V or 240V Loads.
Wiring for timer is shown on following link:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T103

Troubleshoot T103:
1) Manual override is working correctly, and it snaps crisp and clean, and Load turns on-and-off.
That means timer is basically good.

2) Next look to see if yellow dial is rotating.
If dial is not rotating, then 120Volt clock motor needs to be replaced.
Take photo of wiring and mark wires before starting.
Remove two white wires connected to screw terminals 1 and A.
Snap timer mechanism out of box, clock motor is on back of timer.
Use small star screwdriver to remove old clock motor.
Reattach white wires on terminals 1 and A, tighten screws very tight.
Reset current time: lift and rotate dial until current time lines up with silver pointer.

3) If dial is rotating, but gets stuck at certain times, or runs slow, then replace clock motor.

4) If dial is rotating, and trippers are attached to dial, but timer does not turn ON, then trippers are worn down and need to be replaced.
Grainger sells the T103 trippers
http://www.grainger.com/Grainger/INTERMATIC-Timer-Tripper-2E054?Pid=search

5) How Intermatic mechanical timers work:
Dial with ON-OFF trippers is rotated by clock motor.
Trippers on dial contact ON-OFF lever.
ON tripper pushes lever one direction.
OFF tripper pushes lever opposite direction.
Lever moves electrical contacts on back of timer that turn Load ON-OFF.
Manual override lever clicks back and forth with each ON-OFF action.

Sounds like you need new ON pin
http://www.grainger.com/Grainger/INTERMATIC-Timer-Tripper-2E054?Pid=search



The ON-OFF pins rotate around until they come in contact with a lever. The clock motor pushes the pin forward until it clicks the on-off lever. The pins are softer metal than the lever, so the pins wear out.

If you need a new T-103 timer some day > the new timer mechanism can snap right into the old box without changing boxes.

If the dial is not rotating, then you can replace the T100 series 125 Volt clock motor (the T103 clock motor is 125V)

ON OFF trippers are not set correctly.
Timer is not wired correctly.

yes u will, but u will have to make sure one of the motor wires are hooked up that way also, in case it has been moved, here is a link with the diagram u need
