Timer motor on intermatic t103 stoped, will the wg1570 125 volt clock motor work in this model

You have the T103 timer rated 120-240. The clock motor part of timer is 120Volt. This is a very versatile timer, but confusing for non-electrician and electrician alike.
Solve problem by converting timer from T103 to the 240V T104 by changing clock motor from 120V WG1570 to 240V WG1573.
Buy wg1573 clock motor at WW Grainger or drillspot etc.

This simple fix is intentionally designed by Intermatic so their timers are not only adaptable to all electrical needs, but also can be maintained to last 25 years by replacing clock motors and trippers as needed

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.

You posted under T103 Intermatic 120V timer.

Sounds like you wired the timer wrong:
Timer has 120V clock motor and requires Hot from breaker on terminal 1, and Neutral from breaker on terminal A. This will power clock motor.
If you have any of the wires reversed, timer will do what you describe.

WG1573 is a 240 Volt clock motor for T100 series timers.
This means you have T-104 timer.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html
Image shown on link above is T104R outdoor timer.
T104 indoor timer is the same except door does not have rubber gasket.
Terminals are labeled A 1 2 3 4
If this is not your timer, then add a comment.

Following instructions will convert T104 240V timer to T103 120V timer

Clock motor can be replace with identical 120V clock motor from Grainger
http://www.grainger.com/Grainger/INTERMATIC-Time-Clock-Motor-1PNK1?Pid=search

Timer mechanism snaps out and clock motor is located on back.
Remove clock motor with star screwdriver tip

Connect new clock motor wires to DIFFERENT terminals than before.
Old clock was connected to terminals 1 and 3
New 120V clock motor is connected to terminals A and 1

Wiring for 120V T103 is shown on link below.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T103
White neutral wire must connect to terminal A
Black hot wire must connect to terminal 1

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)

T104 timer is for 240 Volt circuits. It has internal 240V clock motor. Clock terminals and timer terminals are connected, so there is no way this timer can control 110V circuit.

T101 timer is for 110V circuit.
T101 has 110V clock motor
Both white neutral wires = terminal A.
Black hot wire from breaker box = terminal 1
Black wire to load = terminal 2.
Grounds = green screw

T103 clock motor is 125 volt WG1570
1) If you bought the 240V WG1573, the clock will not operate
2) If you connected the motor wires to wrong terminals, then clock will not operate.
3) If original box label says T103, but 240V T104 was installed in same box, and you bought wrong voltage motor
4) Test for 120Volts across terminals A and 1, and make sure clock motor matches voltage of timer, and clock motor wires are connected to terminals A and 1.
