Cardale Minor Door Imbalance / Spring Preload Incorrect

Door opens fully but then slowly drifts closed a few centimetres when disconnected from opener.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Slightly under‑tensioned torsion springs, Worn spring cones or set screws slipping, Heavy aftermarket door furniture added without spring adjustment

Safety first: Spring tension adjustments are dangerous and should be done by professionals.

Confirm drift: Disconnect the opener and move the door to various positions. Note where it tends to move on its own.
Check for added weight: Consider whether insulation, windows, or hardware have been added since installation.
Professional adjustment: Have a garage door technician adjust the Cardale spring tension to restore proper balance.
