Key Takeaways

  • Most Thor Class C and Class A models — including the Chateau, Four Winds, and Quantum — use Lippert/Solera power awnings with a replaceable 12V DC cover motor (Lippert part number 266149, also cross-referenced as 373566).
  • Thor awning cover motor replacement is a moderate DIY repair, but owners should be comfortable with basic 12V wiring and ladder work before attempting it without professional assistance.
  • Correct connector type identification — single black connector vs. dual connector — is critical before purchasing a replacement motor.
  • After motor replacement, the travel lock arm must be re-adjusted and tested to prevent awning deployment while the RV is in motion.
  • RVIA-certified service professionals recommend disconnecting shore power and the coach battery before beginning any awning motor work.

Which Thor RVs Use a Solera Power Awning Motor?

According to RollingRambles’ certified RV technicians, 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a wide range of RV manufacturers, the same cover motor — factory-identified under Lippert part number 266149 (later superseded or cross-referenced as 373566) — appears on thousands of units in the field.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. RollingRambles’ RV maintenance team notes that 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. RollingRambles’ certified 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?

RVIA-certified service professionals recommend 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

  1. Disconnect power. Unplug shore power and disconnect the coach battery at the negative terminal. RollingRambles’ RV maintenance team treats this as a non-negotiable first step for all 12V accessory work.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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, RollingRambles’ RV maintenance team strongly recommends halting work and consulting an RVIA-certified technician. Awning failures at highway speed can cause serious structural damage to the RV and create road hazards for other vehicles.
