Automatic Pool Cover Runs Crooked
A cover that runs crooked is usually dragging on one side, sitting on the wrong water level, or no longer square to the tracks. Stop if fabric is leaving a guide. Owners can clear debris and check level. Do not bend a loaded track or shove the leading edge by hand. That is installer work.

Immediate stop-use and safety action
If the fabric is climbing out of a rail, stop the key and keep people off the cover. A crooked run that still stays in both guides can be paused for owner checks. A run that jumps the track is a stop-use condition.
Likely causes and safe owner checks
One dirty rail, low water, or an out-of-square shell will show up as a leading edge that leads on one side.
| Check | Owner can do | Stop and call |
|---|---|---|
| Tracks | Clear grit you can reach from the deck | Rail is bent or missing slugs |
| Water level | Bring the pool to the specified level | Travel still cocks after level is right |
| Standing water | Pump if the cover is designed for it | Bar stays twisted after the water is off |
| Fabric in both guides | Look at both long sides | Fabric has left a track |
| Shell square | Note if the two lengths differ | Do not force a cover to hide out-of-square |

What not to do
Do not pry the leading edge square with a board. Do not grind a track. Do not add weight to the slow side. Those tricks tear gliders and void later service.
When a professional is required
Call when the fabric leaves a guide, the bar is bent, or owner checks do not restore a straight run. Prevention is clean tracks, specified water level, and no travel with a loaded cover.
What to read with this page
Use the parent hub for the product family, then stay inside this cluster for the decision you still have open. The related cards below are the three pages that usually settle the next question without sending you back to a generic search.
If travel is already unsafe, leave the guide and open repair. If you need a preliminary system read, use request system advice with photos of both ends and both long sides.
Square the water and the rails before you blame the motor
Crooked travel is usually one rail dirty, one side low on water support, or a leading edge that is already bent. A motor that still runs both directions is doing its job. Stop and use the repair hub if fabric is leaving a guide.
常见问题
- Can out-of-square pools run true?
- Only with a documented plan from the installer. A cover cannot invent square geometry.
- Does crooked travel mean I need a new motor?
- Rarely as the first guess. Drag and geometry show up before drive failure.
- Can I steer it straight with the key?
- No. Jogging a crooked bar is how the second side leaves the track.
