New to the forum - i have an Intermatic timer like the one pictured above that won't shut off. Haven't seen my symptoms anywhere on the forum, so --- It's nearly brand new, as the previous one stopped working (the gears in the back were no longer turning.) This one worked for a couple months, but in the past few weeks, it turns on at the correct time, but when it gets to the "off" tripper, the dial stops turning, and the switch doesn't turn off. i have moved the tripper, and the dial always stops where the tripper is. I have checked the tripper, and the flanges are not bent, although I did follow one bit of YouTube advice and tightened the trippers with pliers when they slipped around on the dial instead of tripping the switch. I have checked the switch, and it has a firm, solid motion but is not stuck. Short of replacing a nearly new timer, I'm out of ideas. Anybody have a suggestion?
