Which Thor RVs Use a Solera Power Awning Motor?
the vast majority of Thor Motor Coach models built since approximately 2014 are equipped with Lippert Components’ Solera power awning system. This includes popular Class C platforms such as the Thor Chateau, Four Winds, and Quantum, as well as several Class A models. Because Lippert supplies awning hardware across a wide range of RV manufacturers, the same cover motor — factory-identified under Lippert part number 266149 (later superseded or cross-referenced as 373566) — appears on thousands of units in the field.
Owners experiencing a cover motor failure typically report one or more of the following symptoms: the awning fabric cover will not open or close electrically; the motor runs but the cover tube does not rotate; or the control switch produces a click or hum with no movement. a non-responsive cover is most commonly caused by motor failure rather than a wiring fault, though both should be tested before ordering parts.
How Do You Identify the Correct Thor Awning Cover Motor Replacement?
Connector type is the single most important identification factor before purchasing a replacement motor. technicians identify two primary connector configurations used on Solera systems installed in Thor RVs:
- Single black connector: Found on many earlier Solera installations. The motor harness uses one keyed plastic connector.
- Dual connector: Found on later production units and some replacement-market motors. Uses two separate wire leads or connectors.
Owners should physically inspect the existing motor’s wiring harness before ordering. The motor itself is a 12-volt DC, 75-RPM unit designed to fit short, flat, or pitched awning configurations. According to Lippert service documentation, part number 266149 is the original OEM designator, while 373566 is a widely used aftermarket cross-reference. Both numbers appear on compatible replacement motors available through RV dealers and authorized online retailers.
What Is the Step-by-Step Process for Thor Awning Cover Motor Replacement?
completing this repair with a second person present, particularly when working at ladder height on a Class C or Class A chassis. The following procedure is based on Lippert’s published service guidelines for Solera power awning systems and is provided here for informational reference.
Tools and Preparation
- T-25 and T-30 Torx drivers
- Phillips and flathead screwdrivers
- 7mm and 10mm nut drivers or sockets
- Multimeter (for circuit verification)
- Step ladder or RV service ladder
- Electrical tape or heat-shrink connectors
Replacement Procedure
- Disconnect power. Unplug shore power and disconnect the coach battery at the negative terminal. Experienced technicians treats this as a non-negotiable first step for all 12V accessory work.
- Manually retract the awning. If the fabric is extended, use the manual override slot (typically located at the rafter arm head) and a flathead screwdriver or drill with the appropriate bit to retract the awning fully. Secure it with the travel lock before proceeding.
- Access the motor end cap. The Solera cover motor is housed inside the fabric tube at one end of the awning assembly, typically the driver’s-side or street-side end depending on the model year. Remove the end cap cover screws — usually Torx T-25 — and slide the cap off.
- Disconnect the wiring harness. With the cap removed, the motor connector(s) will be accessible. Note the connector orientation with a photo before disconnecting. Use a multimeter to confirm zero voltage at the connector before touching bare terminals.
- Remove the motor retention fastener. A single bolt or set screw secures the motor body inside the tube. Remove this fastener and slide the motor out of the tube. The motor typically weighs under two pounds but may be retained by corrosion on older units; gentle rotation while pulling is usually sufficient to free it.
- Install the replacement motor. Slide the new motor into the tube, aligning the drive spline with the tube’s internal gear track. Reinstall the retention fastener and tighten snugly — do not overtighten, as the motor housing is aluminum. Reconnect the wiring harness, matching the connector orientation documented in Step 4.
- Reinstall the end cap. Replace the end cap and secure with the original Torx screws. Torque should be firm but not forced — the cap housing is typically plastic or light alloy.
- Reconnect power and test. Reconnect the coach battery, restore shore power, and operate the awning through one full open/close cycle using the wall switch or exterior button. Listen for smooth, consistent motor operation with no grinding or hesitation.
- Adjust the travel lock. After confirming correct motor operation, verify that the travel lock arm engages securely when the awning is fully retracted. Per Lippert service guidance, the travel lock must physically prevent awning extension when engaged. If the lock does not seat correctly after motor replacement, re-adjust the lock arm position before the RV is driven.
Important: If the awning does not operate correctly after replacement, or if any wiring appears damaged, Experienced technicians strongly recommends halting work and consulting an a qualified technician. Awning failures at highway speed can cause serious structural damage to the RV and create road hazards for other vehicles.

The Lippert Motor That Actually Survives a Thor Chateau’s Duty Cycle
Thor awning motors fail quietly—one day the fabric retracts fine, the next day you hear the motor strain and quit mid-cycle. The OEM Lippert 266149 is the exact replacement that avoids the part-number roulette and connector mismatches that plague cheaper knockoffs.
What works
- Drop-in fitment; connectors align first try without adapter hunting or terminal crimping on-site.
- Dual-connector design matches both pre- and post-2015 Thor harnesses, eliminating the guesswork on control-box compatibility.
- 75 RPM rated torque holds the fabric tension under wind load without the brown-out stutter you get from undersized knockoffs.
What doesn’t
- Amazon shipping is unpredictable; if your awning fails mid-trip in a remote area, plan for 5–7 days minimum if two-day isn’t available.
- Price premium over Aaiov clones is real (nearly 2x), and some budget-conscious flippers have gotten away with the cheaper equivalent—until they haven’t under load.
I hesitated pulling the trigger on the Lippert over a $40 Aaiov when I was three states away from my dealer, but the moment I had to run a full extend-retract cycle in 25-mph wind, the original spec made sense. Order the Lippert 266149 Solera Power Awning Replacement Motor — 12V DC, 75 RPM, Dual Connectors if you’re not gutting and rebuilding the entire awning assembly.

I replaced mine once and haven’t touched it since; the connectors fit without rewiring.
