I have a Intermatic mechanical/dial time switch. I don't have the specific manufacturer number but similar as to ones many have. Yellow dial. I have reviewed several postings but they all seem to reflect issues where the motor gears are not running etc. My specific problem is the motor is running as are the gears. The dial stopped moving. It is not the tripper pins and the dial is in the correct position where it should turn. Stopped working a few days ago. I can manually turn the pump off and on from the switch. Could it still be a motor issue? I have had clocks where the motor is running but the correct time is never maintained. What other reasons could the dial not move? Thanks.
