Garage Door

We recommend performing the following inspections every 6 months:

• 

  Check lift cables and rollers for visible signs of wear (cable fraying, roller bearings loose or sloppy). Never attempt to adjust or replace the springs, cables or bottom roller brackets yourself as all of these components are under extreme tension and serious injury can result. Call us if you notice any problems with these items.

• 

  Check the balance of the door. Start with the door in the closed position. Pull the emergency release rope to disengage the door from the electric opener. Open the door by hand half-way and release. The door should move easily and stop in a balanced position at the half-way point. If the door wants to drop down or open up by itself from this point either the springs need to be adjusted or they are the wrong springs for the door and should be replaced. Note: all springs are under extreme tension and should only be adjusted by a qualified door mechanic. Serious injury can result if adjustment is attempted without the proper tools and knowledge. A well-balanced door should not weigh more than 3 to 4kg.

• 

  Lubricate the moving metal parts on the door (roller bearings, hinges and springs). Do not lubricate tracks as this is not necessary and will only attract dirt affecting performance. A good quality spray lube is the easiest to use. You may also use a motor oil like 10W30 and wipe off excess oil with a cloth.

Electric Opener

We recommend performing the following inspections every 3 months for safety reasons. Electric openers are capable of producing significant force when opening or closing your door and if not properly adjusted can cause serious injury or death from being hit or trapped by the moving door.

Check the automatic safety reverse sensor on your electric opener. While door is closing grab bottom of door when it is about 1/2 way closed. Door should stop and open back up. If the door is very hard to stop or can’t be stopped at all, adjust the down force sensitivity adjustment knob to a lower number (some brands don’t have numbers and will say increase or decrease sensitivity – in this case you want to increase sensitivity). Re-perform reversing test until door reverses properly. Please note that if the sensor setting is too sensitive the door may reverse under normal operating conditions, if it is not sensitive enough the door will not be safe to use. If you cannot get the reversing sensor to activate the door is not safe to use and you will require a service call to have your opener repaired or replaced.

Place a 2×6 on the floor under the door laying flat. Use the electric opener to close the door. The door should reverse and open upon contact. If the motor keeps trying to close the door after contact re-check sensitivity adjustment. If the door stops on the obstruction it may not be set to close far enough. Adjust the down limit to close the door further. This adjustment should be made without the 2×4 in place so you can see when the door is closed far enough to seal properly on the floor. Re-do 2×4 test after making this adjustment.
