Maintenance & Troubleshooting Tips

• Keep garage door hinges, rollers, pulleys, bearings, and torsion springs oiled to prolong life and maintain smooth operation.
• Test the balance of door springs regularly to ensure proper and safe operation, and to prolong your garage door opener’s life. Your door should be tested by hand to ensure it stops at any position and is easy to raise and lower. Springs should be changed if your door feels unbalanced.
• Inspect safety sensor alignment and keep the area clean of cobwebs and leaves. Safety sensors should be located at the bottom of your garage door track on each side. Most standard safety sensors have an LED light on each one, indicating they see each other if both are lit. This will allow your door to operate safely.
• Change the battery in the outside keypad frequently to ensure proper operation. If your keypad used to light up when pressed, it most likely needs a new battery.
• Regularly look at springs and cables to ensure they don’t look worn or damaged. If a cable looks frayed, call us immediately to have it replaced.
• With the door fully open, place a 1-1/2″ board (or a 2×4 laid flat) on the floor, centered under the garage door. Operate the door in the down direction. The door must reverse on striking the obstruction.
• The outside of your door should be regularly maintained to keep it in good working order. Steel doors should be routinely washed (consult your owner’s manual for proper care). Wood doors should be stained or painted regularly to prevent rotting or warping.
• LED Light bulbs have been known to cause radio interference with some Liftmaster garage door openers. To avoid this issue use bulbs from the approved list here.
