How a Power Awning Fails
Most power awnings have a 12 volt motor in or at the end of the roller tube, a switch or control board, and arms that fold and extend as the tube turns. When something goes wrong, the problem is usually in one of three places: the power supply, the motor, or the arms and mounting hardware.
Start with the simple checks. A weak house battery, a blown fuse, a loose ground or a corroded connection can each make a motor click, run slowly or quit partway. Many power awnings will not move at all when battery voltage is low, so charge the battery and try again before you assume the motor is dead.
If power reaches the motor and it still hums without turning, or only moves in one direction, the motor or its internal gearing may be failing. Grinding, binding, or one arm moving ahead of the other usually means bent arms, worn pivots or loose mounting brackets instead.
Arm and Bracket Damage From Alberta Wind
Prairie gusts and sudden mountain storms are hard on awnings. An extended awning acts like a sail, and one strong gust can bend an arm, crack a bracket or pull fasteners out of the sidewall. Some power awnings have a wind sensor that retracts them automatically, but you should still roll the awning in yourself before leaving the site.
Bent arms rarely straighten well and are usually replaced. The bigger worry is the wall behind the brackets. If a bracket has pulled loose, water can get in through the screw holes and rot the wall framing or cause delamination. At that point you have a structural repair as well as an awning repair, so it pays to catch it early.
After any wind event, look along the brackets for gaps, cracked sealant or loose screws. Then check that both arms sit evenly when the awning is closed.
When a Manual Awning Is the Smarter Fix
Power awnings are convenient, but the motor, wiring and controls are all extra parts that can fail. On an older RV, a manual awning is often the more dependable choice. It works with a spring loaded roller tube and a pull strap, so there is no motor to burn out and it does not need battery power.
Manual is worth considering if the motor has failed and parts for your model are hard to find, if the motor and arms both need work, or if you camp off grid where battery power is precious. Manual awnings are also easier to deal with on the road because nearly everything is mechanical and easy to inspect.
Power still makes sense when the rest of the system is in good shape and only one part, such as a switch or motor, needs replacing. It also makes sense if shoulder or mobility issues make pulling a strap difficult, which is a real concern on longer awnings. Whether a conversion works depends on your awning length, the mounting points and your sidewall, so it is best checked in person.
When to Bring It to Horton in Calgary
Some checks are fine to do yourself, such as battery charge, fuses and looking for visible damage. Leave spring tension work to a technician. The roller tube spring stores a lot of energy and can cause serious injury if it is released the wrong way.
Bring your RV to Horton RV Services in Calgary if the motor hums but will not turn, an arm is bent, a bracket has pulled away from the wall, or you are deciding between a repair and a switch to manual. We can test the electrical side, inspect the arms and mounting points, and check the sidewall for water damage before we recommend a fix. If you book in the fall before storage, the awning will be ready when spring camping starts.
Common questions
Can I retract a power awning by hand if the motor dies?
Many power awnings have a manual override or a way to release the motor so you can roll the awning in by hand, but how it works depends on the model. Check your owner's manual. If you cannot find the override and wind is picking up, secure the awning as well as you can and call a technician instead of forcing it.
Is it safe to leave my awning out overnight?
It is best not to, especially in Alberta, where wind can pick up quickly at night. Roll it in when you go to bed or leave the site. In rain, lower one end slightly so water runs off instead of pooling on the fabric.
Do I need a whole new awning if the motor fails?
Not always. If the fabric, arms and roller tube are in good condition, you may only need a new motor or switch, as long as a compatible part is available. If several parts are worn, a full replacement or a manual conversion may be better value.
