Do you notice your RV awning looking a bit weathered, or perhaps a nasty tear is letting the sun ruin your afternoon shade? You are not alone, as many travelers face the inevitable wear and tear that comes with life on the open road.
Learning how to replace rv awning fabric on electric awning systems is a valuable skill that saves you hundreds of dollars in dealership labor costs. This guide provides the exact steps needed to swap out your old material for a fresh, durable replacement while ensuring your motor remains safe.
We will walk through the essential tools, the critical safety pinning process, and the “pro” secrets for sliding new fabric into place without a struggle. By the end of this article, you will have the confidence to handle this repair like a seasoned technician.
Understanding the Basics of Electric RV Awnings
Before you start pulling on fabric, you need to understand that electric awnings operate differently than their manual counterparts. While manual awnings rely on heavy internal springs that can be dangerous, electric models use a 12-volt motor to handle the heavy lifting.
Most modern RVs use systems from brands like Dometic (A&E), Carefree of Colorado, or Solera (Lippert). While the specific bracket designs vary, the core principle of the fabric attachment remains the same across most electric awning platforms.
The fabric is held in place by “polycord,” which is a plastic bead sewn into the top and bottom of the material. This bead slides into a C-channel on the side of the RV and a similar groove on the roller tube itself.
Essential Tools and Materials for the Job
Preparation is the difference between a one-hour job and an all-day headache. You will need a few basic hand tools and at least one capable assistant, as handling a 15-to-20-foot piece of fabric is nearly impossible solo.
- Two sturdy ladders: One for you and one for your helper.
- Silicone spray lubricant: This is essential for sliding the new fabric through the metal tracks.
- Cordless drill and driver set: You will likely need to remove small retaining screws.
- Non-marring pliers: Useful for gently opening the ends of the awning rail if they are crimped.
- Zip ties or heavy-duty tape: These help secure the awning arms during the process.
- Flathead and Phillips screwdrivers: Standard tools for various hardware components.
- Replacement fabric: Ensure you have measured from the center of the right arm to the center of the left arm.
Avoid using WD-40 or oil-based lubricants on the awning rail. These attract dirt and can stain your new fabric over time; stick strictly to dry silicone sprays for the best results.
Safety First: Pinning the Motor and Arms
Safety is the most critical part of knowing how to replace rv awning fabric on electric awning units. Electric motors have internal brakes, but if you disconnect the fabric, the weight distribution changes, and the arms can shift unexpectedly.
Start by extending the awning about 12 to 18 inches. This gives you enough slack to work but keeps the arms under enough tension to remain stable. Once extended, look for the access hole on the motor head assembly.
Insert a long cotter pin or a heavy-duty screwdriver into the alignment hole to “pin” the motor. This prevents the roller tube from spinning freely once the fabric is removed, which could otherwise lead to a rapid unraveling and potential injury.
Step-by-Step: how to replace rv awning fabric on electric awning
Now that you are prepped and the system is secured, it is time to perform the actual replacement. Follow these steps carefully to ensure a smooth transition from the old vinyl to the new material.
Step 1: Remove Retaining Screws
Look at the ends of the awning rail attached to the RV. There is usually one small screw on each end that pierces the fabric polycord to keep it from sliding during travel. Remove these and set them aside in a magnetic tray.
Repeat this process on the roller tube. Most manufacturers place screws at the ends of the roller tube grooves to keep the fabric centered. You must remove these before the fabric will budge even an inch.
Step 2: Disconnect the Arms (If Necessary)
On some electric models, you may need to unbolt the top of the awning arms from the RV to allow the roller tube to move away from the wall. If your model allows the fabric to slide out the end of the rail without obstruction, you can skip this part.
If you do unbolt the arms, have your helper support the weight. These arms are under pressure and can be heavy. Use your zip ties to keep the arm assembly from expanding or collapsing while it is disconnected from the coach.
Step 3: Slide Out the Old Fabric
With the screws removed and the motor pinned, you and your helper should grab the roller tube. Simultaneously slide the entire assembly—fabric and tube—out of the C-channel on the RV wall.
Once the tube is free from the wall, you can slide the old fabric off the roller tube itself. If the fabric is old and brittle, it might tear; if it gets stuck, apply a bit of silicone lubricant to the groove to help it move.
Step 4: Clean and Prep the Tracks
This is the most overlooked step in the process. Take a rag and a screwdriver and run it through the entire length of the awning rail on the RV. You will likely find spider webs, dirt, and oxidation that act like sandpaper against new fabric.
After cleaning, spray the entire length of the rail and the roller tube grooves with silicone. This creates a “slick” surface that makes sliding the new, heavy fabric significantly easier for you and your partner.
Step 5: Installing the New Fabric
Unfold your new fabric on a clean surface, like a large tarp. Identify the top bead (which goes into the RV rail) and the bottom bead (which goes into the roller tube). Most replacement fabrics have a specific “up” side for UV protection.
Feed the polycord into the roller tube first. Once the fabric is centered on the tube, you and your helper will lift the entire assembly and feed the top polycord into the RV’s awning rail. This is where the second ladder is mandatory.
Slide the fabric down the rail slowly. If it bunches up, stop and have your helper gently pull the fabric taut. Do not force it, or you risk tearing the new vinyl or bending the aluminum rail.
Final Adjustments and Calibration
Once the fabric is fully installed and centered, it is time to reattach any hardware you removed. Reinstall the retaining screws into the awning rail and the roller tube. These screws should go through the polycord bead to prevent the fabric from shifting.
Remove your safety pins or screwdrivers from the motor head. Slowly retract the awning, watching closely to see if the fabric rolls up straight. If it “telescopes” to one side, you may need to slide the fabric slightly on the roller tube to re-center it.
Cycle the awning in and out three times. This allows the fabric to find its natural “seat” on the roller. If your electric awning has auto-stop limits, you may need to recalibrate them according to the manufacturer’s manual if the new fabric is thicker than the original.
Common Pitfalls to Avoid
Even experienced DIYers can run into trouble when learning how to replace rv awning fabric on electric awning units. One common mistake is working on a windy day. A 20-foot piece of fabric acts like a giant sail; a small gust can knock you off your ladder or bend your awning arms.
Another pitfall is failing to check the “bead” size. Most RV rails use a 3/16-inch or 1/4-inch polycord. If you buy a generic fabric with the wrong size cord, it will either be impossible to slide in or will pull out of the track during the first heavy rain.
Finally, never let go of the roller tube if the arms are not secured. The weight of the motor can cause the tube to drop, potentially denting your RV’s siding or breaking the motor’s internal gears.
Maintaining Your New Awning Fabric
Now that your install is complete, you want it to last. The number one enemy of RV fabric is mildew and UV damage. Always try to let your awning dry completely before rolling it up for long-term storage.
Wash the fabric twice a year using a mixture of water and mild dish soap. Avoid harsh bleach unless you have a severe mold problem, as bleach can break down the stitching over time. Applying a UV-protectant spray specifically designed for vinyl or acrylic can also extend the life of your awning investment.
Check the hardware regularly. Vibration from highway travel can loosen the mounting bolts on your electric arms. A quick check with a wrench every few months can prevent a catastrophic failure while you are cruising down the interstate.
Frequently Asked Questions About How to Replace RV Awning Fabric on Electric Awning
Can I replace the fabric by myself?
It is highly discouraged. The length and weight of the fabric and the roller tube make it a two-person job at minimum. Attempting this solo often leads to bent rails or damaged fabric.
How long does the replacement process take?
For a beginner, expect the process to take two to three hours. If you have all your tools ready and a helpful assistant, an experienced DIYer can often finish the job in about 90 minutes.
Is vinyl or acrylic fabric better for an electric awning?
Vinyl is the most common because it is waterproof and easy to clean. Acrylic is more breathable and stays cooler, but it is technically a weave and can “mist” water during a very heavy downpour. Most electric systems come standard with heavy-duty vinyl.
What if my awning motor doesn’t have a pinning hole?
Some newer “direct drive” motors do not require pinning because the gear reduction prevents the tube from spinning freely. However, you should always consult your specific model’s manual to ensure there isn’t a hidden locking mechanism.
Should I replace the motor while the fabric is off?
If your motor has been sounding strained or “crunchy,” this is the perfect time to replace it. Since the fabric is already removed, accessing the motor assembly is much easier and requires less teardown.
Success Metrics for Your DIY Project
How do you know you did the job right? A successful how to replace rv awning fabric on electric awning project results in a fabric that is perfectly centered with no wrinkles when fully extended. The motor should sound smooth, and the hemmed edges should line up with the edges of the roller tube.
If you notice the awning “stalling” halfway through retraction, the fabric might be too thick for the motor’s current settings, or the tension in the arms needs a slight adjustment. Addressing these small issues immediately ensures your new shade lasts for years of camping adventures.
Taking the time to do this yourself not only builds your mechanical skills but also gives you a deeper understanding of your RV’s exterior systems. You are now ready to tackle the road with a fresh look and reliable shade.
Stay safe, take your time with the measurements, and enjoy the comfort of your restored outdoor living space. Happy camping!
