When your Lippert electric slide room starts acting up -- running unevenly, stopping mid-travel, or throwing a control board fault -- the Hall Effect feedback jack is often the culprit. Part number 344792 is the factory right-side jack assembly, complete with integrated mounting plate, designed as a direct OEM drop-in for Lippert electric slideout systems found across hundreds of travel trailers and fifth wheels. No splicing, no adapters, no guesswork on the sensor harness -- this is the part Lippert puts on the production line.
Lippert's electric slide-out systems use Hall Effect sensors built directly into the drive jack assembly to count motor revolutions and relay position feedback to the slide control board. Without accurate feedback from both jacks, the control board cannot synchronize the inner and outer drive units, which causes the slide room to rack, bind, or trigger a safety stop. This right-side Hall Effect jack (344792) restores that position-sensing loop to factory spec.
This assembly includes the slide-out jack tube, the integrated Hall Effect sensor and wiring pigtail, and the mounting plate pre-attached for right-side installation. It is sold as a single unit -- one jack -- which is the correct approach when one side has failed but the opposing jack still tests good. If both sides have failed or the system is being rebuilt, a matching left-side unit should be ordered separately.
Integrated sensor counts jack travel and reports position data to the Lippert slide control board for synchronized dual-jack operation.
Mounting plate and sensor harness orientation are configured for the right-side drive position. Not interchangeable with the left-side assembly.
Jack tube, sensor, wiring pigtail, and mounting plate ship as one ready-to-install unit -- no sub-assembly required in the field.
Genuine Lippert Components part number 344792. Matches factory specifications for fit, harness connector type, and sensor output signal.
Lippert electric slide-out systems use either a single or dual-motor configuration. In dual-motor setups, one motor drives the inner slide tube and one drives the outer, with both motors needing to stay in sync to prevent the room from racking. The Hall Effect sensor in each jack contains a small magnet and a semiconductor that generates a pulse each time a tooth or rotor feature passes the sensor face. The control board counts those pulses from both sides and cuts power to whichever side is running ahead, keeping travel even across the full extension and retraction cycle.
When a Hall Effect sensor fails -- typically due to moisture intrusion, vibration damage to the wiring pigtail, or a cracked sensor body -- the control board either receives a flat signal (no pulses) or erratic pulses. Either condition triggers a fault and stops the slide. Replacing the faulty jack assembly with this factory unit restores the correct pulse signal and allows the board to re-sync the system.
Before ordering, confirm the jack sensor -- not the motor, gearbox, or control board -- is the failed component. Common symptoms of a Hall Effect sensor failure include:
A basic diagnostic step: with the system powered and the slide commanded to move, use a multimeter set to DC volts on the sensor signal wire. A functioning Hall Effect sensor will toggle between approximately 0V and 5V (or 12V depending on system voltage) as the motor rotates. A dead sensor will hold a flat reading in either state.
Installation is straightforward for an experienced RV technician or a mechanically confident owner. General steps include:
