When your Power Gear electric leveling system stops reading jack position accurately, the hall effect sensor is often the culprit. The Lippert 383490 is the factory-correct replacement harness, restoring reliable position feedback so your leveling system operates the way it was designed to.
The hall effect sensor in a Power Gear electric leveling system monitors the rotational position of the jack motor or drive mechanism using a magnetic field rather than physical contact. This non-contact design reduces wear, but when the sensor or its harness fails, the control board loses position data -- resulting in jacks that won't retract fully, error codes on the control panel, or a system that refuses to cycle at all.
Lippert part 383490 is the direct OEM-style replacement harness for this sensor, designed to plug in exactly where the original did with no splicing or modification required. Replacing a faulty sensor harness is one of the most cost-effective repairs in the PowerGear leveling system, and this part is the correct starting point when diagnosing position-related faults.
Hall effect technology reads jack position magnetically with no mechanical wear on sensing components.
Designed as a drop-in harness for Power Gear electric leveling jack systems -- no splicing required.
Complete sensor harness assembly. Restores the wiring connection between the sensor and the leveling control board.
Backed by a limited 1-year manufacturer warranty from Lippert Components.
Power Gear electric leveling jacks use hall effect sensors to tell the control module exactly how far each jack has extended or retracted. The sensor detects pulses from a rotating magnet on the motor or lead screw, and the controller counts those pulses to track position. If the sensor harness is damaged, corroded, or has a broken wire, the count is lost -- and the system either faults out or behaves erratically.
Common symptoms of a failed hall effect sensor or harness include:
This sensor harness is compatible with Power Gear electric leveling jack systems as found on a wide range of fifth wheels, travel trailers, and motorhomes from manufacturers including Coachmen, Forest River, Keystone, Heartland, and others that specified Power Gear (now Lippert) electric leveling from the factory.
