How to Maintain Your Electric Garage Door


For your convenience and safety, frequently test and maintain your door and opener. Make any needed repairs immediately or deactivate the opener until you can.

Things You'll Need

  • Screwdriver
  • Soft Brush
  • Switch Wire
  • Oiling Can And Light Oil
  • 2-by-4
  • Rags
  • Socket And/or Open-end Wrenches
  • Automotive Degreaser
  • Wire Or Metal Tool

Check the door's operation

  • Disengage the opener for manual door operation.

  • Check the door's balance (see How to Fix Garage-Door Tension) and test it for smooth operation.

  • Straighten misaligned tracks: Loosen the screws that secure track brackets to the opening, or the bolts that secure tracks to brackets. Adjust the bracket or track. Then tighten the fasteners to lock the track into place.

  • Clean the tracks with a soft brush or rag. They shouldn't be greasy. Spray on an automotive degreaser and wipe them clean with a rag.

  • Clean and then lubricate roller-wheel bearings and axles or hinge pins with garage door lubricant (available at home stores).

Test and adjust the safety reverse

Troubleshoot a photocell system

  • Attempt to reset the system. Shut off and then restore power to the opener, either at the house's circuit-breaker panel or at the opener's plug.

  • Visually inspect the wiring between the opener and the photocell modules for damage or loose connections.

  • Use a voltmeter to check the wiring for continuity (see How to Troubleshoot Electrical Problems )if you can't see any loose or damaged connections

  • If the wiring is good, either the modules or the main sequencer board in the opener are defective and need to be replaced. Check your Yellow pages under "Garage Door Openers" to find the needed parts.

Tips & Warnings

  • Tracks should be lubricated only with a lubricant designed specially for garage doors. Other lubricants will hold dirt.
  • Install the receiving sensor for a photocell system on the side least likely to have direct sun.
