No and no...
if it is running backwards there is no fixing it...the motor is bad and you will need a new one...

    it wouldn't just start to run backwards if it ever worked correctly before - I have installed way many of these and never encountered that problem

I have a T104 timer that runs my pool pump. I also have a switch that lets me turn on the pump from my house. The switch is wired to the timer. I switched out the T104 with the same and I think I messed up...

The instructions are available from Intermatic if you click on the below link.

240 volts will have two 120 volt lines and a ground(green or bare) or neutral (white) wire.

If your system is 240 volts the Red and Black wires are hot should be individually connected, one to terminal 1 and the second color to terminal 3. The load or pump in your case should be connected to terminal 2 and 4. If you want to wire a switch to the load you need to decide on how you want the switch act, 1) as an auxiliary on 2) as an emergency off. If you want an auxiliary on for the pump, you need a DPDT (Double Pole Double Throw) 40amp switch (what should be in the house). Run the appreciate gage of wire (AWG 8 for 40A) from terminal 1 to one pole of the switch and a wire from terminal 3 to the second pole of your switch. Next run wires from the switch contacts from the two remaining switch terminals to terminals 2 and 4 on the timer matching the Red side on the switch to and Red on the timer and Black side on the switch to Black on the timer. The timer will control the function of the pump, and the switch will turn the pump on when the timer is off. If you only have two hot wires coming from the house attach them to terminal 2 and 4. If you want an emergency stop you need to wire a second DPDT 40amp switch and disconnect the load wires from terminal 2 and 4 and connect each one to the opposite poles of the switch. Using the correct gage of wire you need to connect a red and black wire to the two separate terminals of the switch. When the switch is off the pump will not work but the timer will keep the current time. The color of wires may not be the same in that situation you will need a multi meter to identify the wires.

I need a little more information on the pool sweep timer. Are you using the same timer or just the power? Is the power 120 or 240 volts? When do you want the pool sweep to be active?

Is it possible to buy the timer motor for a Paragon electromechanical timer (Model 7008-20, 208-240 V, 60 Hz)? The timer motor part number is M3100, and the timer is 208-240 V, 3 watt 60 Hz.

1) Paragon is no longer making timers or parts except defrost timers.
7008-20 240V 24-hour mechanical timer is not a defrost timer.
Link below shows folks who might still have Paragon parts

2) To see Paragon timers and manuals:

3) If you want to buy new timer: Intermatic cross-reference guide shows T7802B is correct replacement timer

4) Electric supplies online shows T7802B 4 pole 2NO/2NC

5) Manual for T7802B

Also take advantage of fixya phone service.

Have intermatic t103 time switch, 240 v supply, clock motor not turning. what the correct wiring for the clock. 2 white wires...

Maybe-bad news.
The link below shows wiring for the T-104, T-103 and T-101

For a 240V installation, the correct timer is the T-104, not the T-103
This is because the T-103 clock motor is 120V, and requires additional neutral wire on terminal A
The T-104 clock motor is 240V, and requires only the two hot wires and does not require a neutral.

I suggest you exchange timers and get the T-104
Or run another wire to nearby 120V receptacle and connect Terminal A to the white wires in nearby receptacles. This will give you the neutral that is needed for the clock.
In the absence of a Neutral wire, you can work-around by connecting ground wire to Terminal A >>> but this is NOT Code. You might use the ground wire as a temporary work-around until running additional neutral wire.

Hello can i get the instuctions for tork timer model 1191 please?

According to Intermatic conversion chart, Tork 1191 is same as Tork 1101.

Link to 1101 .pdf
Link to Tork manuals

Tork 1101 is dial-type mechanical timer. Dark pins turn OFF. Light pins turn ON.

Clock motor is 120V
Hot black wire from breaker connects to pole L
Neutral white wire from breaker connects to pole X
Removable bridge connects poles L &1 together
If bridge is gone, Hot from breaker must also connect to pole 1
Black wire to Load connects to pole 2
White wire to Load connects to pole X

Timer can control 240V Load if removable bridge between poles L and 1 is taken out.
Timer clock is still 120V: so 120V Hot still connects to pole L and neutral from breaker connect to poles X
240 V circuit has two hot lines: Hot line 1 and Hot line 2
240 volt Hot line 1 from breaker connects to pole 1
240 volt Hot line 1 to load connects to pole 2
240V Hot line 2 goes directly to Load and does not connect to any pole

Clock doesn't run

Your timer has a manual override. Does 240 circuit work when manual override is turned on? If 240 V circuit works but clock doesn't, then you need another clock.

WW Grainger sells clock motor for $16

If circuit doesn't work when timer override is on, then check circuit breaker.

Both legs of 240 V breaker must be hot for T-104 clock to work. A 240V circuit can appear to have power if only one leg of the circuit breaker is hot. Test breaker or move wires to another same-size breaker to test for sure.

I am replacing the motor (#WG1573-108) for my Intermatic timer WH40. Do both white wires from the motor attach to the load poles, screws # 2 and 4 on the timer? I forgot where the original were wired to....

No, for the Intermatic WH40 the clock motor is connected to the LINE terminals (Terminals #1 and #3) . Which wire connects to where doesn't matter as long as you get one under the #1 terminal and the other one under the #3 terminal. While the WG1573 is the correct part# when using 240 volts, double check the clock motor voltage to make sure says it's for 208-277 volts.

Our intermatic pool pump timer is brand new and is running backward. we bought a second timer and it is also running backward. We had an electrician come out and he can't figure it out either.

You need to check the line voltage being supplied to the timer. It is possible that you have a reversed neutral and common (hot) line providing power to the timer. It is also possible to have another reverse situation with the way the timer is hooked up to the device it is controlling.

Timer motors should only operate in one direction, but if mis-wired, they can operate backwards.

I would need more information about the exact installation you have in order to provide a more thorough diagnois and solution. Info such as is this a 220V-AC installation; is the timer hooked to more than one (1) device (pump, etc.) ; Is there a GFCI breaker on this circuit (there should be!) ; Is this a new installation or a refurbished pool with a new pump & timer?

Please use the "comment" button to supply me with the info requested so I can better address your issue.
