Please Help! The timer moter on my Intermatic T101 keeps burning out withen an HOUR of installation I done this with three (3) units already, All my Neutral wires are connected to the 1st pin, My Hot wire is connected to the 2nd pin and the load (feed to my PUMP) is connected to the 3rd pin. All my ground wired are connected to th METAL BOX of the unit This is a replacement of an old unit that was installed years ago. As a reminder, or if you didnt know, the Intermatic T-101 is ment for 110v pumps. The ON/OFF togel switch works fine and I do get power.
Thank you for your assistance

I have the Intermatic t104 DPST switch controlling my pool filter. The timer works fine but when the switch is tripped by either the on or off clips the timer stops. Still have power and can operate switch manually. How can I correct this.

In reply to Gary Bauldin. You may need to adjust the meshing of the timer motor gear so it runs the clock. I bought a new motor for mine after 20 years and learned about this the hard way.

In reply to steve harper. After a power failure the timer clock can start up backwards, mine has done this several times. I called Intermatic and there is nothing you can do except check it every time you have a power loss. I had to order new trippers as mine have been straightened too many times. I hope this helps

My original timer worked for 5 years then the clock stopped and I heard no sound. Replaced complete new timer assuming 5 years perfect service probably wore it out. But my new timer will not work either. Clock not turning or making any sound. Manual switch works my aerator. No broken or loose wires visible. Any suggestions as to how to test clock feed?

My clock seems to work but but the on and off switch does not turn on the pool pump. I am using the breaker to turn on and off the pool pump. I have Model T40004RTe.
Any advice on how to fix. Thanks Reid

Hello all.
I have the opposite issue. My Intermatic T104M will NOT turn off. Manual override does not stop it either. When I turn on the breaker, the system turns on, even if it shows to be off.
Any suggestions.
Please and thank you.
David
