Micro Switch used to control drive motor
Used on several models of Fleck Valves.
NOTE: This Switch ( 10218 ) and the one next to it ( 16433 ) will sometimes BREAK on the Fleck 9000, 9100, 9500 power head, and this is a result of the DRIVE MOTOR ( 18738 ) running backwards.
The Drive Motor should be REPLACED to solve this issue.
NOTE: Besides physically breaking, this switch can be the problem if the timer completes a full cycle in about 2 minutes and starts again ( never stopping at any of the regeneration cycle positions.
