Garage doors can be fun
Garage doors are an awesome thing, especially if you have an electric garage door opener. Pulling them up and down under your own power can be a wet activity if it is raining and a snowy activity if it is snowing, so it’s just plain nice to have an electric one do the job for you.
If you lose the power to your house, you will find it difficult to get your car out of the garage, so you will have to pull the emergency cord that hangs down from the opener in order to release the lock it has on the door. If you pull this rope, it will disengage from the opener. This will allow you to manually open the door and get your car out. Once you are outside, pull the garage door down by hand and turn the handle so that the door locks.
Your garage door opener will not work when you come back home after the power is on. You will have to go into the house, come through the garage, get on a ladder, and reattach the opener. Release the door lock on the door so that your garage door opener can function properly.
[Note: If you do not do this correctly, you could really mess up the garage door, which would collapse under the strain of being opened when it is locked. You do not want that to happen, so make sure that everything is hooked back up correctly and that the door is unlocked.]
If you have done it right, you will then be able to push the garage door opener button and pull your car back inside. If you have not done it properly, you will destroy your garage door.
I had a friend who got into his car, turned it on, and backed out. He’d forgotten to open the garage door. Things did not go well for him. Always open the door before moving in or out.
