The Garage Door Parts Most Likely to Fail

Garage door systems have many moving parts and all are susceptible to wear, tear and failure. However, three of these components are the most common to experience a problem.


Springs, especially torsion springs, frequently fail and are also the most expensive. Many manufacturers and service companies use un-coated springs rated at about 10,000 cycles. (A cycle is one Open/Close). This type of spring is expected to fail 3-5 years. Retrak Door uses powder-coated commercial grade springs that resist rust and have cycle ratings of 30,000 or higher, meaning a much longer lifecycle. Always ask about the cycle ratings on all springs when considering replacement.


Rollers help guide the door up and down the track. Most companies use a plastic or nylon tire on a steel shaft. These will generally show significant wear within 18 months of normal use. Rollers with bearings are typically better; Ask about the cycle and weight ratings on the rollers your technician recommends.


Bearings are the third most frequent component to fail. A typical garage door should have three sets situated in the middle and both ends of the door. Many doors come with only two bearing sets and one plastic bushing.

Being aware of the garage door components most likely to fail will enable you to make a more informed decision when buying, maintaining or repairing your door system. The result is a longer lasting and smoother operating door.
