Half of the online manual is upside down.

According to the manual, the clock motor that operates the timer requires a separate Neutral wire.
The clock motor is a separate circuit, just like your alarm clock.

The wiring is:
Black-hot-from-breaker connects to timer-black wire
Wire-to-Load connects to timer-red wire

Timer-white wire connects to Neutral.
The Neutrals are white wires twisted together and covered with a wire nut.
Not every box has Neutrals ... in that case, connect timer-white wire to bare copper wire.
Bare copper wires connect back to the Neutral busbar in breaker box.
Attaching your white wire to ground is not code, but it will work.

How to test your wires:
Separate wires
Turn on power
Test each wire to bare ground
Tester lights up on Hot wire from breaker
Now test Hot from breaker to each of the other wires, except ground.
Tester lights up on Neutral

    Thank you Geno_3245 for you very helpful response. I looked on the Intermatic website but did not find the information on the separate power supply to the clock motor. I have it going now and I am grateful to you.

    Put a 4-thumbs up on the answer, and we'll call it square. Glad it worked out. I am in contact with Intermatic regularly when I find things in their manuals that are not clear. They're working hard to keep the customers happy. We all are. Good luck.

    I have the same problem as the original poster, so I was very hopeful when I read this post. I have the same timer and the timer dial does not rotate even when inserted fully, but the manual button does turn the circuit on and off. I tested all the wires as Geno_3245 indicated and everything checked out with one caveat. I have an extra set of wires that feed a light switch for the light in the room with the timer, so my hot wire from the fixture is in a twisted wire nut with the hot wire for the light switch and a pig-tail hot wire that is then connected to the red wire on the timer. Again, everything functions except the timer dial does not rotate, and I have already replaced the timer with a like model with no changes. Any help would be appreciated.

Why when i just installed a new T104 timer yet seems wont turn on with pins

Are you sure that you put the pins on right? They have little projections on the bottom that turn the timer on/off as the cam moves through its 24 hour rotation. The little gear in the back is connected to the motor and because it is spinning that tells you that the motor is definitely good.

I have an Intermatic T104R201. Recently the dial stopped rotating - it was due to the clock motor (I confimred that it was not working thru the visual inspection slot). I replaced the clock motor with...

Take it apart and look at the gears. Clean up the gears and timer. make sure dial is all the way down into place.
Check that white clock wires are connected to terminals 1 and 3
WH40 timer is same mechanism as T104R201 except without fireman's switch.

I have a Roper Model RTW4440VQ2.

If you can rotate the timer to different places and the machine agitates and spins but the timer doesn't advance on it's own, then the timer motor is not engaging the timer, may have a bad gear. Usually you have to buy a whole timer to get a new motor and gear.
Check to see what's available.

Need to set the timer properly. No instructions to follow. Want lights to come on at 6PM and off at 6AM. the timer has red and black pegs on the timer, HEL:P

Experiment with the timer.
Hook up the lights and timer. And read resource link below.
Put the trippers on the dial. Put red at 6pm and black at 6am.
Then manually rotate the dial two revolutions.
Turn the override knob to different setting, and then manually rotate the dial two revolutions.
Watch what the lights do as you rotate timer dial.
Then rotate dial two revolutions until current time lines up with stationary arrowhead located on inner dial.
The clock motor located inside timer rotates the dial, and trippers move small switch that turns lights on-and-off.

Where can I find the manual for the Intermatic Incorporated Timer, Spst-125V 24Hr Mechanical 2 On/Off - PB913N84

There is no manual specific to the PB800-900 series timers.

Timer uses 107TTN222 ON tripper and 107TN221 OFF tripper.
Push trippers onto dial at times you want timer to turn on-off.
Rotate dial until current time lines up with arrowhead located in center of timer dial.
images show that timer has override knob that can be rotated.
Timer has 4 terminal connections. 2 connections are for 120Volt clock motor, and 2 terminals are the switch for turning Load on-off.
Black hot wire and white neutral wire connect to clock terminals.
Switch terminals are dry.
Dry terminals mean they have no power when wires are connected to clock motor.
The switch terminals wire just like ordinary light switch: Power connects to one of the terminals, and wire to Load connects to other terminal. Neutral wire does not connect to switch terminals, just like wiring an ordinary light switch.
Offhand I do not know which set of terminals is for clock motor.
Use continuity tester on each set of terminals.
Clock terminals will show continuity at all times, no matter which position override knob is set.
Switch terminals will show continuity with override knob in one position, but not the other position.

The dishwasher seems to of got stuck on its cycle. when we turn it on it hums quietly but won't do anything else. Any ideas?

I assume you have a knob that turns and that is how you turn it on and have it go through it's cycles??? If that is the case there is a small motor that after you turn the d/w on continues to rotate the knob and makes your d/w go through it's cycle. It sound likr the small gear that the motor uses to drive the timer is stripped. Probably need new timer.

Timer dosn't move.

The timer is normally just a motor and that turns a shaft ( soem have gear reduction setups too) and trigger various functions to happen.. Chances are your motor is bad or one of the power leads is detached. Over time, wires loosen and break free of terminals and motors do wear out.. That's probably your problem,.. Hope that helps..
