A garage door opener usually fails in small steps. A sensor lens gets dusty or knocked out of line, a remote battery dies, a track loosens, and the door keeps running until one day it does not reverse when it should. A house you watch from far away needs someone who owns those small steps.

The safety check every month
Place a flat board on the floor in the door's path. Close the door with the remote or wall button and watch whether it reverses when it meets the board. Then test the sensors: wave an object through the beam while the door closes and confirm it stops or reverses. If it does not, the sensors need cleaning or alignment before anyone uses the door again.
Sensors that drift
Each sensor has a lens on each side of the opening. Wipe the lenses, check that the indicator lights are steady, and make sure neither bracket has been bumped. Do not adjust spring tension or the drive yourself. A spring under tension can cause serious injury, so that work belongs to a trained garage door technician.
Remotes, keypads, and codes
List every remote, keypad code, and phone app that can open the door. Replace remote batteries on a set schedule and write the date in the house folder. Decide who holds a spare remote and where it is kept, so it is not in a coat pocket in another city.
Lubrication and the manual
Find the owner's manual and keep a photo of the page that lists the maintenance schedule. Check the rails and rollers for wear and the hinges for loose bolts. Lubricate moving parts only as the manual directs.
Who calls for service
Name the local person who can meet a technician and watch the door being serviced, and the first phone number you will call. Ask the technician whether one visit covers the sensors, the springs, and the opener, and whether any repaired part comes with a written warranty. For the general safety guidance behind these checks, see the Sources page.
Check these tonight
Find the manual. Run the board test and the sensor test if someone can do it in the house. Write down every remote and who holds it. Put the service contact on the same page as the house folder.
What to take to the doctor
Nothing for the doctor on this one. If your parent has had a fall or a near miss in the garage, mention it at the next visit so the doctor knows how the house is set up.
