A jockey pump that trips repeatedly, refuses to restart, or leaves the controller energized with no motor response often traces back to a worn thermal overload. The OLDLOV0036 Lovato overload assembly restores motor protection on Tornatech JP1 and JP3 jockey pump controllers in the 13–18 amp band.

As a thermal overload relay, it disconnects the starter when motor current remains above the dial setting, then permits reset once the element cools. Replacement is quick: swap the assembly, set the dial to the pump motor's nameplate full load amps, and confirm normal start/stop cycling before returning the controller to automatic.

Fit this 13–18 A unit only when motor FLA lands inside that window; adjacent OLDLOV ranges cover 9–14 A and 17–23 A motors. Cybertronic Controls — veteran-owned, in Hammond, Louisiana — keeps it in stock; call 985-351-5681 to verify your controller model.
