Garage Door Opener Repair – Repairing or replacing an opener is easier and more cost-effective than installing an original opener. Even if in the end you have to replace the whole unit, you already have tracks and springs in place that you can reuse. Many of the tasks involved in repairing or replacing a garage door opener are simple things you can do with a minimum of mechanical skill.
Look for dirty rollers. Remove the roller and clean it in the degreaser or kerosene. Replace the roller and apply a little mechanical oil. Oil all rollers twice a year. Insert a screwdriver into the adjustment slots on the side of the garage door unit on the roof to move the door lock bar in the correct position. Stretch the crooked door rails, and use a screwdriver to tighten the screws on all brackets.
Check the batteries in the external signal units. Check to make sure that the garage door springs are in good condition. There are two types of garage door opener springs: torsion and extension. The extension springs are located above the rails on each side of the garage door. The torsion spring is a single mechanism, the long spring at the front of the garage door opening.
