If your Kwikee 32 series electric steps are no longer retracting or extending when you open and close the RV door, the magnetic door switch is often the culprit. This OEM-style replacement switch restores proper automatic step operation without replacing the entire step assembly. Part number 47-0485 also cross-references as Kwikee part 905323000.
The magnetic door switch is the sensor that tells your Kwikee electric step controller whether the entry door is open or closed. When the door opens, the switch signals the step motor to deploy the steps. When the door closes, it signals the steps to retract. A failed or misaligned switch is one of the most common reasons 32 series steps stop cycling correctly -- and replacing just this switch is far more cost-effective than servicing the motor or controller.
This direct-fit black replacement is manufactured in the USA and backed by Kwikee's limited 1-year manufacturer warranty. It is the correct part for Kwikee 32 series electric sliding step systems.
Designed specifically for Kwikee 32 series electric sliding steps. Drop-in fit -- no modification required in most installations.
Uses a magnetically actuated reed switch -- no physical contact between door and switch body. Less wear, more reliable triggering over time.
Manufactured domestically to OEM standards. Quality materials consistent with original Kwikee step system components.
Backed by Kwikee's limited 1-year manufacturer warranty against defects in materials and workmanship.
Unlike mechanical plunger-style switches, the Kwikee magnetic door switch uses a reed switch inside a sealed housing. A small magnet mounted on the door frame passes near the switch body when the door closes, triggering the switch to signal the step controller. Because there is no physical contact, the switch is resistant to dirt, moisture, and wear from repeated door cycling -- all factors that matter significantly in an RV environment.
When the switch fails, common symptoms include steps that stay deployed regardless of door position, steps that won't deploy at all, or steps that retract immediately after deploying. Replacing the switch is the correct first diagnostic step before chasing wiring or controller issues.
This switch is designed for use with Kwikee 32 series electric sliding step systems. Kwikee 32 series steps are among the most widely installed electric RV steps and are found on a broad range of travel trailers, fifth wheels, Class A, Class B, and Class C motorhomes from manufacturers including Forest River, Keystone, Coachmen, Thor, Fleetwood, and many others.
To confirm fitment, locate the series designation on your step motor housing or in your RV's component documentation. If the step system is identified as a Kwikee 32 series unit, this switch is the correct replacement door sensor.
