How to open a garage door manually

To open a garage door manually, start with the door fully closed, pull the red emergency release cord that hangs from the opener's rail, and lift the door by its handle. A balanced door lifts smoothly. If it feels heavy, stop: a spring is the likely cause.

Chamberlain Group, which makes Chamberlain and LiftMaster openers, gives three reasons to work a door by hand: a power outage, a motor that does not respond, or a damaged opener. An outage ends when the power returns. The other two are a job for garage door opener repair in Ottawa.

What the emergency release does

The red cord hangs from the trolley that rides along the opener's rail. Garaga's power outage article says pulling it disables the part of the opener that pulls the door. After that the door is held up by its springs alone.

Chamberlain Group's instructions sort openers by what you see when you look up:

• A square tube along the ceiling: a square rail opener. Pulling the cord snaps the trolley's release arm upright.
• A rail shaped like a T, flat on top with a leg below: a T-rail opener.
• No rail, and a motor on the wall beside the door: a wall-mount opener, released by a handle you pull until it clicks.

Why the door must be closed before you pull the cord

The springs hold the door up, not the opener. Garaga's springs page puts a typical single door at around 150 lb, and says a well-balanced one should feel like 8 to 10 lb to lift. When a spring is weak or broken, the springs no longer carry that difference.

That is why Chamberlain Group's warning is in capitals. Use the emergency release only when the door is fully closed, if possible, because a door on weak or broken springs may fall rapidly and without warning. It also says never to pull the release handle to raise or lower the door.

So if the door is stuck open when the power goes, leave it open. Keep the car and everyone out from under it, lock the door from the garage into the house, and wait for the power or call. Emergency garage door repair in Ottawa is for that night.

How to open a garage door manually, step by step

In order, from Chamberlain Group's and Garaga's instructions:

• Take a flashlight, not a candle, as Hydro Ottawa's outage advice also says.
• Check that the door is fully closed and that nothing and nobody is in the opening.
• Look at the springs, cables and rollers. Chamberlain Group says not to go on if any of them look damaged.
• Undo any lock on the door itself, such as a side lock bolted to the inside.
• Pull the red cord straight down.
• Lift by the handle, which Garaga says is usually on the bottom section. DASMA's garage door safety tips say never to put fingers between the sections.
• Once the car is out, lower the door by the same handle until it is fully closed.

If the door will not lift

Lower it slowly and leave it. Garaga calls a door that takes real force to lift a clear sign of a broken or worn-out spring. DASMA's opener safety tips say a door that needs two hands is probably out of balance, and that the fix is a trained technician, not a more powerful opener.

A broken spring is not an owner's repair: it is garage door spring repair in Ottawa.

How to put the door back on the opener

Chamberlain Group's steps for reconnecting depend on the rail:

• Square rail: pull the cord toward the opener so the release arm drops back to horizontal, then run the opener through a full open and a full close. If the trolley has not caught the door, run one more cycle.
• T-rail: pull the cord straight down, then run the opener. It reconnects on the next trip up or down.
• Wall-mount: pull the release handle straight down, firmly, until it clicks. Then run the opener.

Garaga says you will hear a click when the trolley catches. If the motor then runs and the door stays put, or only the wall button works, garage door opener not working covers the trolley and the wall control's lock.

Locking a door you are working by hand

A released door is an unlocked door. Garaga's 2017 battery backup article says that if the trolley is not reconnected, anyone can open the garage door by hand.

Garaga's answer is a side lock, fitted inside the door on the second section, with a steel bar that slides into the vertical track. Its outage article adds: unlock it before you reconnect the trolley.

An outage that lasts for days

A T-rail opener has a setting for this. Chamberlain Group says pulling the cord straight down and then back toward the opener locks the trolley out, so the door can be worked by hand again and again. One straight pull down clears it.

Can you open a garage door from the outside?

Only if the door has an outside release. Chamberlain Group describes the exterior emergency release kit as a small round keyed lock, usually near the top of the door. Turning the key and pulling it disconnects the opener; you still lift the door by hand.

Without one, and with no other way in, Chamberlain Group says the door cannot be opened from outside in an outage. Genie's FAQ says opening its openers from outside needs its Emergency Release Lock.

Battery backup: an opener that keeps working

A battery backup runs the opener through an outage. Garaga's 2017 article says a fully charged battery is designed to give 24 hours of standby power and up to 20 full cycles (an open and a close each) at 15 to 25 °C, and recharges in about four and a half hours.

An unheated Ottawa garage in January is a long way from that. Environment and Climate Change Canada's 1991 to 2020 normals for the Ottawa airport put its January daily average at minus 10.0 °C. Test the battery before winter rather than trusting the rating.

Chamberlain's battery backup page says battery backup comes only on DC-motor openers, and that the battery lasts about 1 to 2 years with normal use. When it needs replacing, the opener beeps and its battery light turns red.

Hydro Ottawa asks households to be ready for an outage of at least 72 hours, and Garaga's rating covers one day of that. The openers we supply and install are on garage door openers in Ottawa.

When the door is frozen to the ground

Ice is another reason an Ottawa door will not move: the same normals count 14.0 days a year of freezing rain or freezing drizzle at the airport, 3.6 in December and 3.8 in January.

Garaga's frozen door FAQ says not to run the opener against a door stuck in ice, because it can seriously damage the motor and several parts of the opener. Its steps:

• With the door down, pull the red cord and undo the side lock if there is one.
• Check that no metal part is broken or frozen together, then try the door carefully by hand.
• If it is held, tap the bottom gently with a hammer and a piece of 2x4, then scrape the threshold clear.

To prevent it, Garaga says to run the door at least once a day, clear snow from in front of it, and put a silicone-based lubricant on the bottom seal.
