When your Kwikee 32 Series electric steps stop retracting or extending with the door, a failed magnetic door sensor is often the culprit. This genuine Lippert replacement sensor restores proper door-triggered operation and includes everything you need for a direct swap -- no splicing or fabrication required.
The Kwikee 32 Series is one of the most widely used electric entry step systems in towable and motorized RVs. The magnetic door sensor is a critical part of that system -- it signals the step controller to extend when the door opens and retract when it closes. Over time, the sensor body, magnet, or lead wires can fail due to vibration, moisture exposure, or wiring fatigue.
This Lippert 369299 sensor is a direct, OEM-sourced replacement for the original 905323000 door switch used on 32 Series steps. It is also cross-referenced under Jayco part number 0158878 and Thor part number 0116214, making it the correct service part for a wide range of coach brands that left the factory with Kwikee 32 Series steps installed.
Sensor rests as an open circuit. When the door magnet aligns with the sensor body, the circuit completes and signals the step controller to respond.
Includes the sensor body with 19-inch lead wires, the matching door magnet, and mounting screws. Ready to install with basic hand tools.
Cross-listed under Jayco 0158878 and Thor 0116214. If your coach uses Kwikee 32 Series steps, this is your service part regardless of brand.
Manufactured domestically and backed by a 90-day limited warranty from Lippert Components.
The magnetic door sensor is a two-piece reed switch assembly. The sensor body mounts to the door frame; the magnet mounts to the door itself. When the door is closed, the magnet sits adjacent to the sensor, closing the internal reed switch and completing the circuit. When the door swings open, the magnet moves away, the circuit opens, and the step controller receives the signal to extend the steps.
Because this is a passive magnetic sensor with no moving mechanical parts in the switch body itself, failure is usually caused by broken or corroded lead wires, physical damage to the sensor housing, or a lost or demagnetized door magnet. Replacing the complete sensor-and-magnet assembly at once is the recommended approach to rule out all three failure modes in a single service visit.
A simple continuity test across the sensor leads with the magnet held in place (circuit should close) and removed (circuit should open) confirms whether the sensor body itself has failed.
Installation is straightforward for the DIY RV owner comfortable with basic electrical connections. The sensor body mounts to the door frame with the included screws, and the magnet mounts to the door edge in the corresponding position. Lead wires connect to the existing step controller harness at the door sensor plug. No soldering is required on most installations -- the factory connector is reused.
