I have an Intermatic PF1102T timer which is 11 years old. Beginning several months ago, it randomly would stop turning. If I spun the dial a revolution or two, it would begin turning again. Now it has stopped turning completely. It still operates the pump if I manually turn it to a place on the dial where the pins are raised. Also, the thermostat appears to still turn the pump on at the set temperature. I've seen on some older post where a suggestion was made to only replace the motor (rather than the entire unit). Where is the motor located? When I look in my unit, I see three parts: the thermostat, the relay, and the timer housing. Is the motor inside the timer housing? Because my unit is 11 years old, should I replace the entire unit or just the motor? Thanks for all your help. You folks are awesome.
