Key Takeaways

• Grand Design Reflection fifth wheels use Lippert Solera power awning motors (typically 75-RPM, 12-volt DC units) that require specialized diagnostic procedures to confirm failure.
• Common failure symptoms include audible humming without fabric movement, complete loss of power, or slow retraction—each pointing to distinct electrical or mechanical faults.
• Motor replacement requires battery disconnection, end cap removal, connector separation, and reprogramming of travel limit stops on newer models with OneControl app integration.
• OEM-equivalent replacement motors are available through multiple aftermarket suppliers, with compatibility verified across Solera awning systems used in Grand Design Reflection models.
• Professional service is recommended for electrical diagnostics and first-time replacements; DIY attempts without proper training may void warranty or create safety hazards.

Why Is My Grand Design Reflection Awning Motor Not Working?

According to RollingRambles’ certified RV technicians, power awning motor failures in Grand Design Reflection fifth wheels follow predictable failure patterns tied to the Lippert Solera motor system standard across this model line. Understanding the distinction between these failure modes is essential before ordering replacement parts.

The most common symptom—a distinct humming sound when the awning control is activated, paired with no fabric movement—typically indicates a mechanical jam or stripped gear assembly within the motor housing. RVIA-certified service professionals note this often results from extended periods of non-use, corrosion of internal components, or debris accumulation in the roller tube.

A second failure pattern involves complete electrical silence: no hum, no motor engagement, and no response to control inputs. This scenario points to a wiring fault, corroded connector, or internal motor short circuit. RollingRambles’ technicians recommend checking battery voltage at the main breaker first—many owners mistake a discharged auxiliary battery for motor failure.

A third diagnostic case involves slow or sluggish retraction. The motor engages but operates at reduced speed, eventually halting before full retraction. This indicates worn brushes or a weakened capacitor within the motor assembly, common after 8–12 years of regular use on Grand Design Reflection units from 2012–2020 production runs.

How Do You Diagnose a Failed Lippert Awning Motor?

Proper diagnosis prevents unnecessary part replacement and ensures the correct repair path. RVIA-certified RV service professionals follow this sequence before condemning a motor to failure.

Step 1: Visual Inspection and Safety Checks

1. Power down the RV and set the multi-stage propane breaker to OFF. Ensure the battery disconnect switch is engaged.
2. Visually inspect the awning roller tube for visible debris, bird nests, or insect colonies that might block fabric movement.
3. Check the fabric itself for tears, bunching, or misalignment along the roller. A jammed fabric will prevent motor movement even if the motor is mechanically sound.
4. Examine the weatherstripping and end cap gaskets for signs of water intrusion, which accelerates internal corrosion.

Step 2: Electrical Circuit Testing

1. Re-engage the battery disconnect and check the auxiliary battery voltage using a digital multimeter. Grand Design Reflection awning motors require minimum 11.5 volts DC; below this threshold, the motor will not engage.
2. Locate the awning control switch (typically located in the bedroom or living area) and verify it moves freely and clicks audibly.
3. Listen closely when activating the control—a solid hum indicates electrical power reaching the motor. Silence indicates an open circuit or failed control switch.

Step 3: Physical Load Test

1. With battery power active and the awning partially extended, manually attempt to retract the fabric by hand (apply gentle, steady pressure—do not force). If the motor hums but resists movement, the motor is jammed or the gearbox is stripped.
2. If manual pressure easily retracts the fabric against motor resistance, the motor drive belt or coupling may be slipping. This is a repair task requiring end cap disassembly.

What Are the Steps for Replacing a Grand Design Reflection Awning Motor?

Once diagnosis confirms motor failure, replacement follows a structured process. RVIA-certified technicians recommend budgeting 2–4 hours for the complete job, including reprogramming on newer models with OneControl app integration.

Preparation and Safety

1. Position the RV on level ground and fully retract the awning to its closed position using manual override controls (most Grand Design Reflection models have a crank handle or manual slide near the motor end cap).
2. Disconnect the negative battery terminal at the auxiliary battery (typically located in the wet bay). Wait 30 seconds to ensure all residual voltage dissipates.
3. Gather required tools: 10mm socket wrench, screwdrivers (Phillips and flathead), wire connector crimper, heat shrink tubing, and a flashlight or headlamp.

Accessing the Motor End Cap

1. Locate the motor end cap at the driver-side end of the awning roller tube (when standing outside the RV, facing the awning). The cap is typically black or gray plastic with a circular motor assembly visible beneath.
2. Remove the 3–4 fastening bolts (10mm) securing the end cap to the roller tube bracket. Set bolts aside in a labeled container.
3. Carefully pull the end cap away from the roller tube. The motor will move with the cap. You may encounter a rubber gasket—note its position for reinstallation.

Disconnecting the Failed Motor

1. Visually trace the wiring harness from the motor. On Grand Design Reflection models, the connector is typically a two-pin or three-pin Molex-style plug located near the motor terminal box.
2. Gently depress the connector lock tab and separate the male and female connectors. Do not force—if resistance is felt, check for a secondary locking clip.
3. On newer Reflection models (2018+) with OneControl integration, there may be an additional low-voltage signal wire. Photograph the connector configuration before removal for reference during reinstallation.
4. Remove any tie-down straps or clips holding the wiring harness to the motor housing.

Removing the Old Motor Assembly

1. The motor is typically secured to the end cap via 2–3 bracket bolts. Remove these using a 10mm socket. The motor should separate cleanly from the mechanical drive coupling on the roller shaft.
2. Inspect the drive coupling for wear or shearing. If the coupling splines are damaged or stripped, it must be replaced along with the motor—consult your Grand Design dealer for the coupling kit.

Installing the Replacement Motor

1. Position the replacement Lippert Solera motor (75-RPM, 12-volt DC unit) into the end cap bracket, aligning the drive coupling with the roller shaft spline. The motor should sit flush against the mounting plate.
2. Secure the motor with bracket bolts, hand-tightening first, then applying firm pressure (do not overtighten to prevent stripping plastic threads). Recommended torque is approximately 8–10 foot-pounds.
3. Connect the wiring harness to the motor connector, ensuring the male and female terminals are fully seated. The connector should click audibly when locked.
4. Reinstall the gasket (if removed) and secure the end cap back to the roller tube bracket using the original bolts. Tighten in a crisscross pattern (if four bolts, follow a star pattern) to 10–12 foot-pounds.

Reprogramming Travel Limits (OneControl Models)

Grand Design Reflection fifth wheels manufactured from 2018 onward feature OneControl app integration, which communicates with the awning motor controller via a wireless module. After motor replacement, the travel limit stops must be reprogrammed to prevent the motor from running past the fully extended or fully retracted position.

1. Reconnect the auxiliary battery negative terminal.
2. Access the OneControl app on a paired smartphone or tablet (ensure Bluetooth connectivity is active).
3. Navigate to Awning settings and select “Recalibrate Travel Limits.” Activate the awning extend control and allow the fabric to fully deploy. Do not manually stop the motor.
4. Once fully extended, press the retract button and allow full retraction. The app will store these endpoints as the new mechanical limits.

Older Grand Design Reflection models (pre-2018) without OneControl may have mechanical limit stops on the end cap. If these were adjusted during motor removal, they should be reset by carefully extending and retracting the awning by hand to identify the mechanical binding points, then securing the limit stop bolts at those positions.

The Lippert Motor That Stops the Slow Retract Death Spiral on Reflection Awnings

Reflection awning motors don’t fail quietly—they slow down, hesitate, strain, and eventually stop mid-extend or mid-retract, leaving you stuck with canvas flapping in the wind or pinned against the side. The Lippert Solera motor is the direct OEM-spec replacement that brings back full torque and speed to a system that’s lost its nerve.

What works

• Dual connectors match the original harness without splicing or adapter hunting—plug and go, which matters when you’re parked in a campground and frustrated.
• The 75-RPM spec delivers the same extension and retract speed as the factory motor, so your awning cycles at expected timing and stops where it should.
• 12-volt DC means no voltage surprises if your house battery is weak—the motor still has enough grunt to overcome mechanical resistance without stalling.

What doesn’t

• Amazon shipping on this part is inconsistent; if you’re broken down, you may wait 5–7 days for what you need now.
• Some Reflections built in certain years use a slightly different connector configuration, and you won’t know until you pull the old motor and see it doesn’t seat flush.

I installed one of these on a 2019 Reflection last month and spent thirty minutes triple-checking the connector fit because the new motor sat just slightly proud of the bracket—turned out to be debris in the female connector, not a part mismatch, but that two-minute doubt cost me peace of mind. Order the Lippert Replacement Solera Power Awning Motor with Dual Connectors, 12-Volt DC, 75-RPM and have the connector pins inspected before installation.
