Short answer: When the door will not budge and you are already running late, a short, orderly set of checks resolves a surprising share of so-called emergencies without a service call. Work through these in order, and just as importantly, know the point where continuing to push buttons or force the door does real damage. That line is where the money is either saved or spent.

Start here: power, remote, and the lock button
First decide whether you are looking at an electrical problem or a mechanical one. If the opener motor makes no sound at all, check the obvious power path: the outlet the opener is plugged into (garages often share a GFCI that can trip), the breaker, and whether the plug was knocked loose. Milpitas winter storms bring brief outages that can quietly reset or unplug things overnight. If the motor runs from the wall button but a handheld remote or keypad does nothing, start with a fresh battery in the remote. And check one button that fools people constantly: many wall consoles have a 'lock' or vacation switch that intentionally disables all remotes. Bumped or held down, it produces exactly the symptoms of a dead remote while the wall button keeps working, so a quick press of that button is worth trying before you assume anything is broken.
The door opens but won't close, or reverses right back up
When a door goes up fine but refuses to stay down, the photo-eye sensors are the prime suspect nearly every time. Look at the opener and the sensors for a blinking or red indicator, which signals the beam is broken or misaligned. Clear anything sitting in the beam near the floor, including recycling bins, bikes, and cobwebs, then gently nudge the sensors until both indicator lights glow steady, and wipe the lenses. Even low winter sun coming straight down the driveway can wash out a sensor and stop a close. A useful diagnostic: if the door will close only while you hold the wall button down, that hold-to-close behavior is the opener specifically telling you the safety sensors are the reason it will not close on its own.
When to stop DIY and use the manual release
Stop troubleshooting the moment the picture changes from electronic to structural. If the door is jammed, visibly crooked, off its track, or the motor grinds while the door barely moves, forcing it further can bend tracks and turn a modest repair into a big one. Use the red manual-release cord only when the door is fully closed, because releasing a partly open door that has a failed spring lets it drop hard. To secure a home when the door is stuck open, release it, lower it carefully by hand, and lock it. Here is the clearest signal of all: if the door feels extremely heavy and will not lift by hand, a spring has almost certainly broken, and that is a same-day professional repair rather than a driveway fix. Simpler service visits such as sensor realignment or a roller swap commonly land in the lower range of repair pricing, while spring and cable work costs more, so it helps to know which category you are in before you call.
