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

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 http://www.inyopools.com/controls_intermatic_timer_parts.aspx

Will these fit the Model PF1202T Timer?
 Reply

A  Answered on 4/29/2015 by InyoPools Product Specialist Robert M.

Hello Ronny - The T101M (120V) would fit the PF1202T box but it is not the correct mechanism. The correct mechanism is the T104M (220V).

I have a pool timer Model # T101P which I need to replace. The enclosure is fine can I replace the clock only? The Model is T101 MD89 would this be a match?
 Reply

A  Answered on 5/21/2015 by InyoPools Product Specialist Patrick P.

Yes if your enclosure is fine then this would be be the correct timer mechanism replacement for the T101P. This would be the complete insides of the T101P minus the outer enclosure / casing.

I have an old intermatic timer that has quit working. It shows the model number as 89 13N66. What is the current replacement?

Hi Steve, The Intermatic Timer Mechanism Only 120V will be the correct replacement or the this can also be a replacement depending on the enclosure you have.

Hey Steve, I have m/n T12404R dual timer controller. One of the timer motors has stopped working. I've seen your step by step guide for replacement but, can't seem to locate a correct p/n for just the timer motor. Can you help?
 Reply

A  Answered on 5/3/2016 by InyoPools Product Specialist Lennox H.

Hi Bobby, The WG1573-10D will be the correct replacement motor for the T104M timer used in the T12404R unit.

I've got lights on my walkway and the timer isn;t working. I will set the time and it doesn;t keep accurate timing. Also, if I put the switch to manual it switches the lights on, but, the timer has no affect on the lights turning off or on. I'm assuming that the motor needs to be replaced. The model is T101R, what timer model should I order? Thanks

A  Answered on 5/7/2016 by InyoPools Product Specialist Lennox H.

Hi, This T101M Mechanism will be the correct part if you want to replace the entire unit or WG1570-10D will be the replacement motor.

I have a T1202 M1. Would this be the appropriate replacement?
 Reply

Hello Rick - The T101M (120V) would fit the PF1202T box but it is not the correct mechanism. The correct mechanism is the T104M (220V). I don't see any replacement for t1202 M1, you might try reaching out to Intermatic 815-675-2321 to see if there is something other than t1202.

I noticed Terminal 1 and wires connected to it have turned black with 2 to 3 inches of the covers on the wires have been melted. Pump and clock are working. I turned off the timer. I don't know what caused the melting of covers on the wires. What do you suggest\?s Thanks, Fred

Hi, Fred. I suggest replacing the timer mechanism along with the wires to and from the breaker making sure that you're using the proper wire size.
