Garage door opener repairs
frequently need a qualified garage door technician to perform,
but there are repairs that you can do yourself to save money.
The one repair that a uncertified person should not attempt is
the replacement of a torsion spring in a roll up garage door.
The energy stored in a coiled up spring can cause severe injury
to anyone not trained to do the job.
There can be many reasons for a garage door
failing to open. Over time, track or door misalignment can
occur causing the system to bind and fail. First have a look
around the floor and see if there is anything that has
obviously fallen off onto the floor. Anything found would be a
decent clue to the problem.
Next check the tracks for any obstructions.
Sometimes a horizontal track can start to droop downward over
time until the door begins to stick. Wind can cause the door to
move one or both of the vertical tracks, that are frequently
lighter than the horizontal ones. It is common for lighter
vertical tracks to be held by insufficient brackets to keep it
Occasionally the tracks can be damaged or
dented by something banging into them. Give the tracks a good
check over, and if they seem okay then check the door itself.
Make sure it has not come out of alignment and that it is
straight vertically. If the side of the door is damaged in any
way it can easily become stuck in the tracks.
This type of damage to tracks or door can
sometimes be fixed by hammering out the dent, though it's best
to replace the affected section of track since more problems
will likely come up in it's weakened state. In this case you
are advised to get a professional to do the job since it could
require the whole door to be taken down for the repair.
Sometimes the rollers and hinges can get
damaged. A broken roller can be replaced by unbolting the hinge
and taking the roller out of the track. Reverse this to replace
the roller. The procedure is quite simple and easier to do than
to explain! If you have to tap the bolts out, use a block of
wood to hammer on to prevent damage to the bolts. Make sure
that you tap the bolt fully in before tightening the nut.
The bottom rollers where the cables attach have
to be replaced with door up, and if any of the bottom rollers
are affected make sure that you take the tension off the cable
first. You won't make that mistake twice! You must also support
the door panel before doing any of this or you could break it.
A suitable sized thick piece of wood can be used for this.
If your springs are damaged or worn and need
replaced, get a professional to deal with torsion springs,
normally attached to double garage doors. They are under very
high tension and are dangerous to anybody who is not trained.
Extension side springs are easier to replace. Disconnect the
opener from the door using the emergency release cord then open
the door completely, and hold it open with C clamp attached to
a track right up to a roller so that the roller cannot
Now disconnect the two ends of the spring: one
will be connected to the garage door track and the other to a
pulley. Make sure that any safety cables are removed first.
Attach the spring in the same way as it was before, then
replace the safety cables, disconnect the C clamp and do
everything in reverse order. Reconnect the opener and remove
the support from the door.
If the opener itself goes wrong, stops working
or the door opens by itself, then first check the remote. Make
sure that the batteries are OK and that the light is on. Check
out the opener for a short. This can sometimes cause a door
opener to operate erratically. Use a multimeter if you have one
to check out the circuits.
It would be unusual for the remote to go wrong
other than a drained battery, and the openers generally work
fine unless they are not maintained properly. Obviously make
sure that power is getting to the motor, and the remote is
sending a signal.
If your garage door stops working properly, it
is usually in the mechanics rather than the electrics. If you
keep the whole system maintained properly and clean then you
should rarely have to carry out a garage door opener
