Battery disconnect off means no auto retract at all. Motor and sensor work runs **$450 to $3,000**. ## How are powered awning motors and wind sensors diagnosed? Awning motor and sensor repair tests supply voltage, motor current draw, control module output and wind sensor trigger behavior, then recalibrates sensitivity and relearns limit positions. Rancho Santa Margarita owners get this done at our Yorba Linda shop, where the retract logic can be verified on shore power and on battery alone. - A motor that clicks and blows a fuse is usually a bound roller - One direction only is almost always a relay in the control module - Sensors mounted to a rigid part never see the motion they need - Auto retract does nothing when the battery disconnect is open ### Key facts | Item | Value | | --- | --- | | Price range | $450 to $3,000 (2 to 12 labor hours at $260 per hour) | | Labor rate | $260 per hour (Module diagnostics bill at the $285 diagnostics rate, one hour minimum) | | Typical turnaround | 1 to 4 shop days (Control modules for older powered awnings can be slow to source) | | Estimate | $150 written (A $150 estimate charge applies, credited against the repair if you proceed) | | Sensitivity setting | Calibrated for canyon gusts (Factory default is a compromise and it is wrong for this area in both directions) | | Systems handled | Lippert Solera Power, Carefree Eclipse and Travel'r, Dometic 9100, Girard | A powered awning adds three things to the assembly that a manual one does not have: a twelve volt motor inside the roller tube, a control module that decides what the motor does, and in most modern systems a wind sensor that can order a retract without anybody pressing anything. All three are diagnosable with a meter and a clamp, and all three get replaced far more often than they need to be. The wind sensor is the part worth understanding properly, because in this area it is the difference between an intact awning in November and a very expensive morning. It is also the part most owners misunderstand. A wind sensor is not a guardian angel. It is a small circuit that needs power, needs to be mounted somewhere that actually moves, and needs a sensitivity setting appropriate to where the coach is parked. ## What a powered awning adds, and what each part can do wrong The motor lives inside the roller tube on most systems, which is elegant and also means the awning has to come apart to reach it. The control module sits behind a wall panel and handles direction, current limiting, travel limits and, on systems fitted with one, the wind sensor input. The switch is usually the simplest part in the chain and it fails more often than the module does. Each component fails with a recognisable signature. One direction only is a module relay. A click and a blown fuse is a mechanical bind, not an electrical fault. Over retraction that crushes fabric into the rail is lost limit positions. Nothing at all is usually the fuse, the switch or the ground. Reading those signatures correctly is what keeps this from being an expensive parts cannon. - One direction only: relay inside the control module - Click plus blown fuse: bound roller, motor is fine - Over retract or short extend: lost limit positions, needs a relearn - Dead with no click: fuse, switch, ground or battery state ## How a wind sensor actually works, and what it cannot do A wind sensor detects movement, not wind. It is a small motion sensing module, wireless on some systems and hardwired on others, mounted to a part of the awning assembly that flexes when a gust gets under the fabric. When the motion it reads exceeds the configured threshold, it sends a retract command to the module and the awning rolls itself in. That description contains all of its limitations. It needs twelve volts, so an awning on a coach with the battery disconnect open has no protection whatsoever. It needs to be mounted somewhere that actually moves, so a sensor bolted to a rigid part of the frame reads almost nothing regardless of what the fabric is doing. And it needs a threshold that reflects reality, because a value that is too fine retracts every time a truck rolls past and a value that is too coarse waits until the arms are already loaded. It is also strictly reactive. The awning starts retracting after the gust arrives, and on a full length canopy that retraction takes twenty or thirty seconds. A sensor buys margin. It does not make an awning safe to leave out overnight, and no manufacturer claims otherwise. > **note:** Girard systems use an adjustable sensitivity dial on the controller. Carefree and Lippert implementations expose settings differently. We set whichever is fitted to a threshold that suits inland Orange County rather than leaving the factory value. ## Calibrating a wind sensor for canyon conditions Factory defaults are set for nowhere in particular, and inland Orange County is a genuinely awkward place for a wind sensor. Ordinary afternoon conditions in Rancho Santa Margarita bring steady breezes that a sensitive setting will read as a threat, so owners get nuisance retracts and then, entirely predictably, turn the sensitivity down or switch the feature off. Then the offshore flow reverses in October and the same site sees gusts three times as strong arriving after dark. The setting that stopped the nuisance retracts is now the setting that does nothing until an arm is already bending. We calibrate for that gap deliberately: coarse enough that a steady afternoon breeze does not trip it, fine enough that a genuine gust does, and we verify by triggering it rather than by trusting a number on a dial. There is one more check that gets skipped everywhere. We test the retract with the coach on shore power, then again on battery alone with the charger unplugged. Most awnings will retract happily on a fifty amp pedestal. The night that matters is the one where the coach is on battery, the battery is at partial charge, and the module has to find the current to run a motor against a wind load. ## Why the motor is usually innocent Awning motors get replaced far more often than they fail. The reason is that the two most common complaints, a dead awning and an awning that trips its fuse, both point somewhere else. A dead awning is usually a fuse, a corroded switch or a ground. A fuse tripper is usually a bound roller, a seized bearing or fabric jammed against the rail, and the motor is doing exactly what a protected motor should do. An amp clamp settles it in about ten minutes. A healthy motor pulls hard for a second, then drops to a steady figure and holds it across the full travel. A motor pinned near stall current the whole way is not failing, it is overloaded. Fitting a replacement in that situation resets nothing and the same fuse blows on the same cycle. ## What motor and sensor work costs This bills at $260 per hour from the mechanical and electrical department. Module and control diagnostics bill at the $285 diagnostics rate with a one hour minimum, credited against the repair if you authorize it. Parts carry standard markup, sales tax applies to parts and materials, and labor is not taxed. A corroded switch, a replacement fuse and a sensitivity recalibration is two hours. A motor, a control module, a new sensor and a rebuilt feed circuit on a large powered awning is twelve. A $150 estimate charge applies, credited against the repair if you proceed. Control modules for older powered awnings are the usual source of delay. ## When a sensor did not save the awning Owners occasionally want to pursue a claim on the basis that an automatic retract failed to operate. Those are difficult files. Carriers look at whether the awning was extended, and a system that did not trigger is hard to distinguish after the fact from a system that was never powered. The evidence is largely gone by the time anybody looks. What helps is a record. If the awning is on a system that logs faults, we pull them. We record sensor test results, sensitivity setting and battery state at the time of service, so if a subsequent event occurs there is a documented baseline rather than a recollection. That is worth having whether or not a claim ever follows. ## Coaches most often fitted with powered awnings Powered awnings arrived first on higher end coaches and have since worked their way down the range. Diesel pushers, luxury Class A units and destination fifth wheels are where we see the most sophisticated implementations, often with multiple awnings, lead rail lighting and integrated sensors. Camper vans are the other growth area, usually with a compact cassette awning and its own control. ## Cost $450 to $3,000, based on 2 to 12 labor hours at $260 per hour. Written repair estimate is $150, credited in full against an authorized repair. All work is performed in shop. ## Questions and answers ### Does a wind sensor protect my awning while the RV is in storage? Only if twelve volts is present. A wind sensor is a powered circuit and the retract needs the motor to run. With the battery disconnect open, or the house bank flat, nothing will happen no matter how hard it blows. Awnings should be stowed manually before a unit goes into storage. ### Why does my powered awning roll itself in when there is no wind? The wind sensor is either contaminated or set too sensitive. It reads motion rather than wind, so dust on the sensor, a slammed door or a truck passing the site can all trip it. Cleaning it and recalibrating the threshold resolves most cases without replacing anything. ### What sensitivity should a wind sensor be set to in this area? Coarse enough that a normal inland afternoon breeze does not trip it, fine enough that an offshore gust does. Factory defaults suit neither. We set the threshold and then verify by deliberately triggering the sensor, rather than trusting a dial position, because the two do not always agree. ### My awning extends but will not retract. Is the motor bad? Almost certainly not. A fault in one direction only points at a relay inside the control module, since the motor uses the same windings both ways. We confirm by measuring voltage at the motor leads while commanding each direction. Present one way and absent the other puts it squarely in the module. ### The awning motor keeps blowing its fuse. What is wrong? Something is stopping the roller from turning. A seized bearing, fabric jammed against the rail or a bent arm all produce stall current, and the fuse is protecting the circuit exactly as intended. We find the mechanical bind first. Replacing the motor before that just repeats the failure. ### The awning over retracts and crushes the fabric. Why? The control module has lost its stored limit positions, usually after a battery disconnect or a deep low voltage event. It no longer knows where either end of travel is. Running the limit learning procedure re establishes both stops in a few minutes and is regularly mistaken for a failed motor. --- Source: [OCRV Center](https://ocrv.me/services/awning-repair/awning-motor-and-sensor-repair/).
