The direct OEM replacement solenoid for Lippert hydraulic power unit pump assemblies. Rated for 12-volt continuous duty service, this solenoid keeps your slide-outs and leveling jacks operating reliably -- purpose-built to handle the sustained electrical loads that hydraulic systems demand.
Hydraulic solenoids are a common wear and failure point in RV slide-out and leveling systems. When a solenoid fails, the pump may run but produce no hydraulic pressure -- or may not energize at all. The Lippert 161394 is the correct OEM-spec replacement for five Lippert hydraulic pump assembly models, restoring full function without modification.
Rated for 100% continuous duty at 12 volts, this solenoid handles sustained on-time without overheating -- a critical requirement for hydraulic applications where the pump may remain energized for extended periods during slide deployment or leveling cycles.
100% continuous duty cycle -- handles extended energized periods without thermal failure, unlike intermittent-duty substitutes.
Designed for standard 12V DC RV electrical systems. Direct plug-in replacement for original Lippert pump solenoids.
Confirmed compatible with five Lippert hydraulic pump assembly part numbers -- no guesswork on compatibility.
Carries Winnebago cross-reference part number 18223101705, simplifying warranty and service record documentation.
This solenoid is a direct replacement for units installed on the following Lippert hydraulic power unit pump assemblies:
Hydraulic solenoids experience heat, vibration, and repeated current cycling every time slides extend or retract and every time leveling jacks cycle. Over time, the solenoid coil can develop an open circuit, the plunger can stick, or internal seals degrade -- all producing the same symptom: the pump runs but no hydraulic function occurs, or the system is completely unresponsive.
Before replacing a full pump assembly, verify the solenoid by checking for 12V at the solenoid terminals during activation and testing coil resistance with a multimeter. A failed solenoid is a fraction of the cost of a pump replacement and is a logical first diagnostic step.
