Why the age range matters here
About 43% of San Marcos homes were built in 2000 or later, including roughly 15% from 2010 onward, while 27% are older than 1980; the median year built is 1996 (ACS 5-year data, 2020 to 2024). A newer garage is likely to have an opener with sensors, a keypad and often app control, where many faults are settings or signal problems. An older one may have original framing, extension springs and an opener that predates current safety features, where faults tend to be mechanical and heavier. Start with the symptom below that matches yours.
It starts down, then reverses
This is usually the photo eyes. Check that both sensor lights are steady, that nothing sits in the beam and that neither bracket has been bumped. On a west-facing garage, low afternoon sun shining straight into the receiving sensor can blind it, so the door reverses for no visible reason late in the day. Shading the sensor or swapping its sides with the sender often cures that. If the eyes are fine and the door still reverses partway, the door may be binding, which is a repair call.
It will not respond at all
Check the outlet, the breaker and the wall control's lock setting before anything else. On openers with a battery backup, a battery cooked by summer heat in a closed garage can fail without warning; most units chirp or flash when it is weak. If power is present and the door still will not move, pull the release only with the door fully closed and both springs intact, then try lifting by hand.
It hangs crooked or one side is lower
A cable has slipped or snapped. Stop here: do not run the opener, do not try to level the door, and keep people clear. The guide to broken garage door cables shows how to confirm it from a distance.
It is too heavy to lift, or you heard a bang
A spring has broken. On older San Marcos homes it may be an extension spring along the track; check that a safety cable runs through it before going near. On newer homes it is usually a torsion spring on the shaft over the door, and the matching spring is often near the end of its life too.
What the urgent visit covers
For the mechanical cases, the door is secured in place, the broken spring or cable is replaced (both sides when the pair has aged together), the door is rebalanced, and the opener is reset and tested for reversal. For a pre-1980 garage, the jambs and track brackets get a look too. The full list of first steps for any urgent failure is on the emergency garage door repair page, and routine work by home age is on the San Marcos garage door repair page.

San Marcos emergency FAQs
My app says the door is closed but it is open. Is that an emergency?
The door being open is the emergency, not the app. Check whether the door moves from the wall button. If it does, close it and look at the app or Wi-Fi later. If it does not, unplug the opener and call.
The door reverses only in the late afternoon. What is going on?
Most likely sunlight hitting the receiving photo eye. Shade it or move the sender and receiver to opposite sides. If the door also strains or slows near the floor, the track or rollers may be binding in the heat, and that needs a repair visit.
My house is from the 1970s and a spring broke. Is the repair different?
It can be. An older door may use extension springs, which need safety cables, and the wood holding the track brackets is checked before the door is put back in service. Converting to torsion springs is an option to discuss once the door is safe.
