I have an intermatic pool timer and when I switch the power on, I can hear the pump try to start for a split second. It kind of sounds like something is stuck in it. I took the motor apart, it turns freely, and put back together. I tried it again, the same thing. I found that if I hit the timer box, it will turn on. So I thought it was a loose wire or something. I turned the power off, checked all of the connections but everything is tight with no corrosion on anything. But still, the same thing when I try to turn it on. Sometimes, when I hit the timer box, it will run for a while, then stop, and vice-versa. Sometimes when the timer is on but the motor will not run, the motor will just suddenly start. I checked the voltage and I will always have power to the line side (240v), and when I turn the switch on and the motor not run, the power on the load side is 0v, but when I hit the box and the motor turns on, the power is 240v. I installed a new capacitor on the motor about a month ago thinking that was the problem but that wasn't it either. I took the individual timer out of the enclosure, and sanded the contacts on the back thinking it's not getting a good connection, but nope. Any suggestions?
