I have the T104 with the heater controls, however I removed the heater a few years ago, it has been completely removed from the plumbing circuit. My timer is having contact issues - the motor works fine but when it trips on, many times the pump will not start unless I flip the manual switch back and forth. Can I replace my unit with the heater controls with this one, since I no longer have any need for it to control the heater?

A     Answered on 9/7/2018 by InyoPools Product Specialist Lennox H.

Hi, Randy. Yes, you can.

My panel is the T40004RT3, the motor on the back of the current timer says WG1573-5 60 Hz, I _believe_ this one, the T104M is the correct timer but I wanted to double-check? Thanks.

A     Answered on 8/20/2018 by InyoPools Product Specialist Lennox H.

Hi, Joe. Yes, this T104M Mechanism is the correct replacement.

I have a T104p3 timer. I need to replace the board, motor makes sound but clock does not turn. I picked up a T104M at the local big box store, got it home and it does not have as many lugs as the timer I have. What is the correct board with 5 lugs across the bottom? Thanks Mike

A     Answered on 7/21/2018 by InyoPools Product Specialist Lennox H.

Hi, Mike. The T104M is the correct replacement based on your model. There is not another model or version of the replacement mechanism for the T104P3 timer.

A     Answered on 7/5/2018 by InyoPools Product Specialist Hector F.

I have a T101 timer that failed. Label a bit faded and hard to read. Operates manually. Checked trippers , seem ok. What is model # for clock / motor timer mechanism? I think its 220v but would welcome info on 110v also. Thanks

A     Answered on 4/18/2018 by InyoPools Product Specialist Lennox H.

Hi, Richard. The T101 Timer you have is a 110 volt unit, not 230 volts. You will need the Intermatic Timer Mechanism Only 120V - T101M

?     Asked on 11/27/2017 by Bear

Ok I am a strong believer in simplicity and all these Intermatic timer switches are confusing me.Why do you make a 120V and 220V timers?? Is it for efficiency, the need for more power or simply a stronger application? Do all of the inside timer mechanisms themselves work in all of the Dial boxes no matter what they're rated for? They certainly look like they would being almost identical in site.Anyway I thought I'd ask those questions because I've been looking for the answers for two hours.TYOU

A     Answered on 11/28/2017 by InyoPools Product Specialist Alex V.

Bear, The reason why there are 2 different voltages is some older homes will only have 115/120v and newer homes will have 230/240v. The internal parts are not the same except for design. The "guts" will be rated for the voltage as well. 

?     Asked on 11/2/2017 by

I have the PF1202T timer on my pool. The problem I am having is the timer clock moves correctly, but when it gets to the ON or OFF mark it stops and does not make the switch turn ON or OFF. The timer not working is for the pump. I currently manually turn it on and off. I have a sweeper set on auto on the second timer and it is working correctly. Do I need a new timer for the pump?

A     Answered on 11/3/2017 by InyoPools Product Specialist Lennox H.

Hi. You may want to start by replacing the timer trippers. If that does not work then you will need to replace the entire mechanism.

Model# T104.......probably 20 years old and still looks new. Is it possible for the timer motor gears to spin as seen through the view slot but have the clock wheel never move? If the clock is pulled to set time, all feels perfectly binding or ratcheting, etc. Motor is running and spinning it's gear but wheel refuses to move.............GG

A     Answered on 8/3/2017 by InyoPools Product Specialist Lennox H.

Hi, GG. The timer motor can go bad over time. If the wheel is not spinning then the WG1573 motor will have to be replaced.

A     Answered on 5/25/2017 by InyoPools Product Specialist Patrick P.

This item does not work on the Jandy Aqua Switch J1104R. You will require the Jandy 7152 Timer with Wiring Harness if you don't need the wiring harness then you can go with this Intermatic PB913N66 Timer Only as a replacement for the J1104R.

Hello I need a timer for a T40003RT3. I am not sure if this is the correct timer, my actual timer box label states the follow: In rainproof (type 3R) enclosure for indoor/outdoor use. Suitable for swimming pool/spa applications and for direct connection of underwater lights. 100AMP. 120/240 VOLT OR 120/208 VOLT SINGLE PHASE (THREE WIRE) AC. IS this the correct one?

A     Answered on 5/11/2017 by InyoPools Product Specialist Lennox H.

Hi. The correct replacement timer mechanism is the T103M which is a 12hr, 120V. We do not have this item available.

Hi, This timer would not work, you will need p/n T10450. We do not sell just the mechanism.

?     Asked on 12/30/2016 by Matt

In the T30004R panel with two timers, are both timers the same replacement part? I know the 'low' timer is wired from the breaker and the "high" is piggy-backed onto the first.

A     Answered on 1/3/2017 by InyoPools Product Specialist Lennox H.

Hi, Matt. The T30004R Controller only comes with one T104M Mechanism. However, another T104M can be added or a T106M to operate a dual speed pump.

?     Asked on 12/26/2016 by Matt

I have the T30004R with 2 timers. One for the low pump and one high. My pump was running continuously so went to look at the timer. The time was incorrect so I reset it and went back to check, it hadn't moved. However I looked thru the view hole and the motor was still turning the gears. I detached the motor from the clock. The clock side gears move freely with no slipping noted. The motor side gears can be turned manually with no slipping noted. How is that possible? What should I replace

A     Answered on 12/28/2016 by InyoPools Product Specialist Adam Y.

Good morning Matt, Sounds like it is wired wrong. You can see this if you watch the gears when it is on and off if they stop when it is on then the lead wire is not on the right terminal.

Hello- Per Intermatics schematics for that PF1222TB  the T104m Intermatic Timer Mechanism Only 220V is the correct mechanism.

Replaced a t104m timer , but the timer only works when I manually turn the pool motor on. I thought I replaced the wires correctly but I must have missed something. Any suggestions?

A     Answered on 9/30/2016 by InyoPools Product Specialist Lennox H.

Hi Barry. If the timer only works when manually switch it might be that the trippers are not set or installed properly. Checking the trippers would be my suggestion.

Hi Randy, The Intermatic T104M is the replacement for the Paragon T104-71M.

?     Asked on 5/24/2016 by Scott

I currently have an Intermatic model #T21004R timer. If I want to replace the whole unit, which model # do I purchase? I have been operating the switch manually and have been reluctant to purchase anything new, because mine reads that it is a 60 amp switch and mostly all that I have looked at, are only 40 amps. This unit runs both the pool and spa together, hence the need for a 60 amp model......I suppose! Thanks in advance for any suggestions and/or help.

A     Answered on 5/24/2016 by InyoPools Product Specialist Patrick P.

Hi Scott, We do carry the Intermatic T21004R Timer 60 AMP and that is what I would suggest for your set up.

The Polaris timer works correctly, but the Pool timer has quit moving. I can turn it on and off manually, but the timer does not move with the time of day. Is this the part I need to replace, and if so, is it hard for us to replace?

A     Answered on 3/16/2016 by InyoPools Product Specialist Lennox H.

Hi Debbie, This would be the part I would recommend, in some case you could replace the motor WG157310D. If you're not comfortable working with electricity you can have a professional complete the installation or review our How To: Replace an Intermatic T104 Clock Motor and or How To: Install an Intermatic T104 Timer for DIY installation instructions.

We have a guide here showing How To Install a Pool Timer Mechanism and it is not too difficult. This timer will not work on 110V you would require the T101M 110V Timer Mechanism.

How do I know wheather I need the T101M or the T104M?

A     Answered on 3/9/2008 by InyoPools Product Specialist Patrick P.

T101 or T104 should be on the inside door of your current timer or somewhere on the timer. If you cannot find this information you can unclip the timer clock mechanism and on the back of the timer there will be a motor. If there is a part # of WG1570 or 120V marked on the back of the timer motor then you would require a T101M 120V timer mechanism. If there is a part # of WG1573 or 240V marked on the back of the timer motor then you would require the T104M 240V timer mechanism. You may view or purchase these timers through this link
