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.

Thanks!

    It's a 220V-AC circuit, no GFIC breaker (getting one) only the pump is hooked up to the timer. I bought it a year ago but only had it installed a month ago by a licensed electrician. It worked fine for a while and then stopped. I can hear the motor clicking, but the dial doesn't turn. I'm thinking about taking the timer out and fooling with the mechanism

Pool timer


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.
Resources:
http://waterheatertimer.org/How-to-replace-Intermatic-clock-motor.html
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T104
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

Can i change the model T101P3 timer from 110 to 220?


1) Yes. Change clock motor from WG1570 to WG1573
Wiring is same as T102 timer:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T102
http://waterheatertimer.org/How-to-replace-Intermatic-clock-motor.html

2) If new pump motor is 2-speed, then converted T101P3 cannot handle 2-speed pump.
Use T106 timer, or T1906 timer:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#2-speed
http://waterheatertimer.org/How-to-wire-T1906-Intermatic-timer.html#pool

3) New T106 or T1906 timer mechanism will snap into T103P enclosure without changing boxes.
Any intermatic timer will snap into Intermatic enclosure.
Other brands of timer can adapt to Intermatic enclosure using Tork IAP adapter bracket.

Can't get timer to work. Wires R red, blue,green. Is red hot, blue neutral?


You should've fixed your Intermatic timer for $20 with new clock motor or trippers.

GE 15306 is 120Volt timer.
You probably have 240Volt power to pump.

Copy following links to help solve problem, and repair the Intermatic timer so you can return the GE for refund at Home Depot.

Why is my timer runnung backwards


Timer is not identified.
Analog timers have clock motor.
If the gears strip out, then timer can run backwards.
Some timers have replaceable clock motors, such as Intermatic and Tork box timers, and pool timers.
http://waterheatertimer.org/How-to-replace-Intermatic-clock-motor.html
While small plug in timers generally do not have replacement parts.

Pool time switches pool on, but off does not trip off, and can't do it manual. When I push it on off, the pool pump tries to stop but continutes running. Have to use breaker box.


Model number of timer is not known.
Is this new installation? Or installation that worked before and recently stopped working?
If the manual override lever on timer does not turn Load on-off, then 1) wiring is wrong or 2) timer has gone bad or 3) pump has a short.
I suspect a short since you say the pump 'tries to stop running.'

Model 4001-ov trips the circuit breaker.


Assuming you have Paragon 4001 40 amp 120Volt timer
By-pass the timer so only pool pump is connected to breaker.
To do this, move wire from terminal 2 and connect to terminal 1.
If breaker no longer trips, then replace timer with Intermatic T101
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T101
Crossover wiring: Paragon terminal 1 goes to Intermatic terminal 1.
Paragon terminal 2 to Intermatic terminal 2.
Paragon terminal 3 to Intermatic terminal A
If breaker keeps tripping after bypassing timer, then tighten wires on circuit breaker and test again.
If breaker keeps tripping, then move wires to another same-size breaker.
http://waterheatertimer.org/How-to-replace-circuit-breaker.html
Breakers trip when they sense overheating.
If motor is causing problem, you might need electrician to track down source of overheating.

Can you send a scematic showing how to wire an intermatic pool pump timer to a polaris intermatic timer so that when the pool pump shuts off so will the polaris pump yet the polaris timer clock continues...


No. I don't have a wiring schematic without knowing what voltage you are using, specifically what Intermatic timer you have, specifically what wires you have coming from breaker box, what wires are on the pump, and what pump rating plate says, what the wiring diagram shows on side of pump, whether you are wiring a 2-speed pump to a single-speed timer, specifically what is the polaris timer clock, and why this pump needs two timers if that's what you mean.
Add a comment with specific information so electrician is not guessing.

Changing Pool Timer


As long as you get a new timer that is 220/240v and is the same amperage or larger, you should be fine. Wiring would be the same.
