Any garage door
and/or operator needs regular safety checks and maintenance to keep
operating properly and safely. The garage door is often the most used door
in a home or business. The biggest potential problem lies in the spring
system used to lift the door, whether the door is hand operated or if there
is an operator.
An extension spring system usually has springs on either
side of the door which are in the stretched position when the door is down
and are at rest along side the horizontal track when the door is up. When a
spring or cable breaks loose, the spring will fly through the air, unless
there is a safety cable installed through the length of the spring.
The newer and safer lift system for doors consists of
torsion springs mounted on a steel bar on the wall above the door when the
door is down. The bar runs through the center of the springs, so that if a
spring breaks, the bar prevents the spring from flying loose. Also, if a
cable breaks, the bar limits the range of motion.
Following is a list of annual do-it-yourself maintenance for
keeping your door and operator running at their peak performance.
Lubricate all moving parts of the door
with light household oil, including:
lift cables at the bottom bracket
lock hardware where surfaces move
torsion spring (between mounting cones only)
steel rollers at the joint of the shaft and head
Tighten loose hinges (straighten or
replace defective hinges)
Check rollers for broken wheels, bent
shafts, worn out bearings
Check door and track for loose or
missing bolts/screws; tighten or replace
Check cables for wear and fraying at
bottom bracket and drum
Check for bent track
Do not put grease in the track as this
collects dirt and impedes rollers
Lubricate the gear in the operator
Check for worn operator belts, tapes, or
We recommend that broken springs be replaced by an
experienced technician. Improper release of spring tension has caused
serious injury or even death. We also recommend that springs be replaced in
pairs (if applicable) so that each spring will provide the same pull. A
door should be in good working order to cause the least amount of strain to
the operator attached to the door.
carry repair parts for most doors.
It is important for home owners to keep their manuals when
they purchase a garage door or operator. These manuals have
information about common problems and solutions for their door and / or
operator. They also have information about disconnecting the door
from the operator, which is important if a power outage occurs. An
operator manual explains how to recode a remote when the battery has been
replaced. A suggested place to store these manuals would be on an
interior garage wall.
We get many calls from customers saying that their remotes
do not put their door down. They say they need to press and hold the
wall button for the door to go down. These symptoms can indicate that
the safety sensor eyes (mounted near the bottom of the door track) are
probably misaligned, dirty, damaged, or that the remote may be locked out
from the wall button. Simply a leaf or other obstruction hanging from
the bottom of the door can cause the door to reverse.
These problems can be a simple fix done by the
homeowner. The eyes need to be pointed directly toward each other or
may need cleaned. The bottom of the door should be kept clean also. We prefer to discuss the system with the customer
and help them to solve these problems. This saves the customer a
service call and helps them to understand more about their operator and
door system. If a problem persists, then a service call is required.
