Could not figure out what exactly was wrong until I watched your video. Thank you so much!

No B.S. on and on. Straight to the point! Saved me much time. Thank You!

your clip should be on the top of list for diagnoses of pool timers. Thank you

Great video Arnold,great clarity on the visual and you just answered every question I had about the timer!

Excellent informative presentation. Could not determine why the the pool would not turn off and viewing this presentation solved the mystery. Have ordered a new T104 switch. Thank you.

I really appreciated your video, learned how it works, and found the same issue with the worn out part. I have replaced the Intermatic timer with a digital timer for $12.

Bro, great video thank you for this video. I searched everywhere to see what was wrong with mine and I couldn’t find any video

You CAN fix this problem (and without replacement parts). If your lever switch looks worn (as in the video - and it was on mine), notice that the wear is only on the 'front side' (toward the camera). The little protrusion of the 'ON' pin is 'slipping off' the front of the lever switch. Take the 'ON' pin, and identify the leg with the special protrusion. Now take that leg (and ONLY that leg) and bend it 'down' (away from the thumb screw) about 1/8 to 1/4 inch. Now the protrusion will extend far enough to engage what is 'left of' the lever switch (don't bend it too far or it will also hit the gears). Note: If you aren't comfortable making 'warranty-voiding modifications', don't do this. The bent pin worked for me. It took two minutes, and the timer should last a few more years...

Thank you. Same here. I just hesitated to take it that far apart. I'll be doing that this week.

this is the ONLY video that solved my problem! the screw on the front dial of mine was a small torx (don't know the number) but once off there was the problem!!! TY! TY! TY! TY!

You were right on the money. Thanks for saving me time.

Cheers! More detail inside and no frills, GREAT VIDEO!!!

Thank you for this video. I had the exact same issue with the T104 model for my pool. Will replace with a new one from Home Depot as there is not a way to repair the worn down metal piece.

Great detailed video - thank you. now I know what the problem is.

gonna check it out excellent video Arnold thanks you

My "On" clamp was crooked and jamming the gear preventing it from turning - see you take the dial off helped - thanks

Thought that might be my problem and now I know it is ------ thank you so much !!

That was a great video! Now I understand why my pool pump turns OFF after like 10mins ‘coz of that worn out metal...

Thank you man this is exactly what was happening to my security lights.

Man that’s just my problem. Thank you

Finally an answer to my problem. Thank you!

T101 10 years, and now worn out. Looked at a lot of fix videos, but this is the only one I found with the right diagnosis. I like how it abruptly ends - basically saying, get a new timer. Are the newer models designed differently to prevent this?

Very helpful, thank you very much sir!!!

Great info. Thanks.

thanks for the knowledge.

Man that’s just my problem thank you

How do you fix the timer arm getting stuck on the tripper and not turning the pump on?

My exact problem and this was only video to explain it! Except there’s no fix?

My question is if I'm turning it off and on manually then it gets jammed as I try n turn it back on...why would it get stuck

thx u

Has anyone found a replacement part? Or do I need to buy a whole new timer?

Mine did not turn off

Waste of time for me watching this as you have no solution. You either need the part that's broken (which you can't find), or just replace the whole dang timer.
