There are many reasons why a garage door opener becomes malfunctions. The most common reason is the misaligned garage door tracks. Another reason is the poor adjustment of the chain, either it is too loose or too tight. Weak or broken garage door springs are another reason that will ultimately fail the garage door opener. Let’s go into a few of the common reasons in detail and when to get a garage door repair service to get some solutions. First of all, I want to share what happens to the garage door opener if the metal tracks are not aligned correctly. Dented and misaligned garage door tracks do not allow the garage door to run smoothly and evenly. The main point is that perfectly aligned tracks put the least amount of resistance on the motor of the garage door opener. If the tracks have been misaligned, damaged, or uneven then a huge amount of pressure will destroy the opener. The extra resistance will ultimately burn the motor. Garage door tracks are easy to fix. The loose mounting brackets can be tightened with the help of a screw. If the tracks are shaking or wiggling, simply add more brackets. You can buy them from any hardware store. The second garage door opener malfunctioning cause is the chain itself. Regular cleaning and oiling of the chain will help the motor to last longer. If the chain of the opener is too loose it will cause the motor to slip. In this case, the opener runs fast than its normal speed and the motor will work continuously according to its timer and eventually bunt out. Make sure that the chain is adjusted properly, meaning no slack and no over tighten. The too-tight chain can put extra pressure on the sprocket of the mechanism. The third killer reason is the coil of garage door springs. They are extremely dangerous to adjust on your own as they hold a great amount of pressure. According to the garage door experts, the torsion springs should be replaced every 5 to 7 years. Too tight or weak springs can put a great amount of pressure on the motor. It is strongly suggested that hire professional garage door technicians to adjust and replace the garage door springs.
