Wayne Dalton Down Travel Limit Set Too Long

Door closes hard and slams into the floor before stopping.

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

Close limit over-adjusted, Incorrect rail length or mounting height, Weak or broken springs causing fast descent

Safety first: A slamming door can cause damage or injury. Keep people and pets away until corrected.

Adjust close limit: Reduce the down travel setting so the door stops just as it contacts the floor without excessive force.
Check door balance: Disconnect the opener and test door balance. If the door drops quickly, springs need professional service.
Inspect mounting height: Ensure the opener rail and header bracket are installed at the correct height per Wayne Dalton instructions.
