Inside every Tornatech JP-series jockey pump controller, a thermal overload relay stands between the starter and the motor, breaking the circuit if current runs high for too long. OLDLOV0031 is the genuine Lovato overload assembly for that job on motors in the 1.6–2.5 amp band, fitting Tornatech JP1 and JP3 jockey pump controllers.

Setup takes a single adjustment: rotate the dial until it reads the full load amps (FLA) stamped on the jockey pump motor nameplate. Plan on replacing the assembly if the pump drops out under normal load, demands repeated resets, or the controller energizes without ever starting the motor — classic indications the relay's thermal elements have drifted out of calibration.

Check that your motor nameplate FLA sits between 1.6 and 2.5 amps before ordering; adjacent ranges, including 1–1.6 A and 2.5–4 A assemblies, are also in stock. Cybertronic Controls is a veteran-owned supplier in Hammond, Louisiana — reach us at 985-351-5681 for fitment help before you order.
