Merlin Door Out of Balance – Weak Springs

Door will not stay open; it slowly closes when stopped mid‑travel with opener disengaged.

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

Springs losing tension with age, Broken or partially cracked spring, Incorrect spring rating for door weight

Safety first: Do not attempt to operate a heavy, unbalanced door with the opener; it can damage the Merlin motor and rail.

Check for broken springs: Look above the door for a visible gap in the torsion spring or hanging extension springs.
Do not attempt DIY spring replacement: Call a qualified door technician to replace or retension springs.
After repair: Reprogram Merlin opener limits and force settings to match the newly balanced door.
