  • Reversal Test: Look for a reversal button. If it is not present, you should call to have it replaced. Openers manufactured after January 1, 1993, are required by federal law to have reversal buttons.
  • Force Setting Test: Hold the bottom of your door as it closes. If it does not reverse readily, the force may need adjusting. Check your owner's manual for details. Test again after readjusting.
  • Additional Safety Devices: Many openers have additional safety devices, such as photo eyes or edge sensors to prevent entrapment. Test this by "tripping· the line to make sure they are still functioning. If the door does not respond, check your owner's manual for necessary adjustments and reinstallation measures.

  • Visual Inspection: Look at the springs, cables, rollers and pulleys for signs of wear. If you suspect problems, have a qualified person make repairs. Door equipment is under high tension; so do not attempt to adjust it if you do not have the proper training. If handled improperly, serious injury may result.
  • Lubrication: Regularly lubricate the moving parts of the door. However, do not lubricate plastic parts such as rollers and idler bearings. Consult either the owner or manufacturer's manual for recommendations.
  • Door Balance: Test periodically, starting with the door closed. Use the opener to release the door. You should be able to then lift the door with out any problem. It should stay open about three feet above the ground. If not, it is out of alignment and needs adjustment. Have this done by a qualified service technician.

WARNING - Springs are under high tension. Only qualified persons should adjust them.

Garage door springs, cables, brackets, and other hardware attached to the springs are under very high tension and, if handled improperly, can cause serious injury. Only a qualified professional or a mechanically experienced person should adjust them, but only by carefully following the manufacturer's instructions.

The torsion springs (the springs above the door) should only be adjusted by a professional. Do not attempt to repair or adjust torsion springs yourself.

A restraining cable or other device should be installed on the extension spring (the spring along the side of the door) to help contain the spring if it breaks.

WARNING! Never remove, adjust, or loosen the screws on the bottom brackets of the door. These brackets are connected to the spring by the lift cable and are under extreme tension.
