# Awning Motor and Sensor Repair: Cost, Hours and Process in Hacienda Heights Awning motor and sensor repair covers the 12 volt motor inside the roller tube, its limit cams, the control switch and wiring, and the wind sensor that retracts a powered awning automatically. Most complaints here are limit drift or a voltage problem at the wall pass through rather than a failed motor. ## Specifications - Price band: $500 to $3,500 - Shop hours: 3 to 14 hours - Turnaround tier: Systems and electrical - Insurance billable: no - Parts lead time: 10 to 20 business days for tube motors and control modules, 5 to 12 business days for switches, sensors and harness parts - OEM brands: Carefree of Colorado, Dometic, Girard, Solera, Lippert ## The motor lives inside the roller tube, which changes everything On nearly every powered patio awning the motor is a tube motor: it sits inside the roller tube with its gearbox and limit mechanism, and the fabric winds directly onto the housing that contains it. That single packaging decision drives most of what is true about servicing these. It means the fabric has to come off to reach the motor, so a motor job and a fabric job share most of their labor. It means the wiring runs through the tube end and into the arm or the wall, where it flexes every cycle and corrodes at the pass through. And it means the limit mechanism is mechanical and inside the tube, which is why limits drift rather than fail cleanly. The practical upshot at intake is that we ask about fabric age on every motor complaint. If the canopy is near end of service and the motor needs to come out, doing both at once avoids paying twice for the same de-tensioning and re-tensioning of the tube. ## Limit cams, travel drift and over-roll The most common powered awning complaint is not a dead motor. It is travel that has drifted: the awning stops short of full extension, or it keeps rolling past the stow position and starts to over-roll the fabric in the wrong direction. Both are the limit mechanism. Cams inside the tube tell the motor where the ends of travel are, and their reference can shift after a fabric replacement, an obstruction event, or simply wear. Nothing is broken and no part is required. What is required is access to the adjustment and knowledge of the specific family's procedure, because the adjustment differs meaningfully between assemblies. Over-roll deserves specific attention because it damages fabric. Once the canopy starts winding the wrong way onto the tube, it loads the hem and the poly cord in a direction they were never designed for, and a week of that produces a fabric problem on top of a limit problem. If your awning is over-rolling, stop using it under power until the limits are set. - Extension limit set short, so the fabric never tensions correctly - Retraction limit set long, producing over-roll and hem damage - Limit reference lost after a fabric replacement - Obstruction events that shift the reference without breaking anything - Thermal cutout inside the motor, misread as an intermittent limit fault ## Wind sensors, false triggers and the fault that matters more A wind sensor on a powered awning reads motion or acceleration at the assembly and commands a retraction when it exceeds a threshold. It is a protective device and it prevents a large share of the arm damage described on the awning arm page. False triggers are the complaint we hear: the awning retracts on a calm night, or every time someone closes the entry door hard. The usual causes are a sensor mounted where it reads structure rather than wind, a sensitivity setting left at the extreme, a loose sensor bracket that amplifies every input, or a marginal supply voltage that the control logic reads as an anomaly. The fault that matters more is the silent one: a sensor that no longer triggers at all. Nobody complains about it, because a sensor that does nothing is invisible until the wind event it was fitted to catch. So we function test the sensor on every powered awning job rather than only when it is the stated complaint. And we do not defeat a sensor that is false triggering. We find out why and correct it, because disabling a protective device to silence a symptom is how arms get bent. ## Cost, hours and the diagnostic hour The band on this page runs from a switch, ground and connector repair at the low end to a tube motor with a control module and a sensor at the high end. Labor is three to fourteen hours at the mechanical and electrical rate of $260 per hour, with tube motors and modules commonly 10 to 20 business days out. Because the answer here is produced by measurement, this leaf carries the in depth diagnostic at one hour of $285, credited against an authorized repair. Voltage is read at the motor under load rather than at the battery, and that reading alone resolves a meaningful share of no move complaints: a corroded ground at the sidewall pass through, a switch with burned contacts and a tired house bank all present exactly as a failed motor. One practical note for anyone stuck with an awning out. Most powered assemblies have a manual retraction path, and it varies by family: a crank access, a clutch release, or a specified procedure at the motor. Find out what yours is before you need it, because the alternative on a windy afternoon is watching a protective device you could not reach. ## Not included - We do not defeat or bypass a wind sensor. Where a sensor is faulting we repair or replace it rather than disabling a protective device. - Mechanical arm and pivot faults presenting as an electrical complaint are addressed on the awning arm page. - House battery and shore power faults that present as a slow awning are onboard electrical work, quoted separately. ## Questions **Why does my powered awning retract by itself on a calm night?** A false wind sensor trigger. The usual causes are a sensor reading structure rather than air, a sensitivity setting at the extreme, a loose sensor bracket that amplifies door slams and footfalls, or a marginal supply voltage the control logic reads as an anomaly. All four are correctable. We will not simply disconnect the sensor, because it is the device that saves the arms. **The awning stops before it is fully out. Is the motor weak?** Usually not. That is the extension limit set short, which is a mechanical adjustment inside the roller tube rather than a failed part. Limit references drift after a fabric replacement or an obstruction event. The adjustment procedure differs between assembly families, which is the main reason this is shop work rather than a switch you can find in a manual. **My awning keeps rolling past the stowed position. Should I keep using it?** No. That is over-roll, and it winds the canopy onto the tube in the wrong direction, loading the hem and poly cord in a direction they were not designed for. A week of it turns a limit adjustment into a limit adjustment plus a fabric replacement. Stop operating it under power until the limits are set correctly. **Does the fabric have to come off to replace the motor?** Yes on nearly every powered awning, because the motor lives inside the roller tube that the fabric winds onto. That is why we ask about canopy age on every motor complaint. If the fabric is near end of service anyway, doing both at once means paying for the tube de-tensioning and re-tensioning labor once instead of twice. **Can a wind sensor be tested, or do you just replace it?** It gets function tested. A sensor that no longer triggers is the fault nobody reports, because a protective device doing nothing is invisible until the day it was needed. We test the trigger and the commanded retraction on every powered awning job, not only when the sensor is the stated complaint. --- Source: https://ocrv.club/rv-slide-out-repair/awning-motor-and-sensor-repair OCRV Center, 23281 La Palma Ave, Yorba Linda, CA 92887 Phone (949) 799-3387.
