A garage door that won’t open sends most Colorado homeowners straight to the phone, and sometimes that’s the right call. But in a surprising number of cases, the fix takes less than five minutes and costs nothing. Before you book a service visit, run through these seven checks. You might save yourself a call, and if you do need a technician, you’ll hand them useful information about what you’ve already ruled out.
This sounds obvious, but it’s the first thing a technician will ask about. If your garage door opener isn’t responding at all, no light, no sound, and no movement, the opener may have lost power.
Check that the opener is plugged in (the outlet is usually on the ceiling near the unit), and test the circuit breaker for that outlet. Colorado’s afternoon thunderstorms are notorious for tripping breakers and kicking GFCI outlets into protection mode. If an outlet in your garage was wired as a GFCI or shares a circuit with one, press the “reset” button on the GFCI outlet and try the opener again.
Dead remote batteries are one of the most common “my garage door won’t open” calls we receive. If the wall button inside the garage opens the door but the remote doesn’t, the remote is the problem, not the door system. Replace the batteries with fresh ones (most remotes use CR2032 or AA/AAA cells) and test before anything else.
If neither the remote nor the wall button opens the door, try the wall button alone. A functioning wall button rules out the remote and points the issue to either the opener motor or a safety system. A non-functioning wall button usually means a wiring problem between the button and the opener, or a logic board issue in the opener itself.
Every garage door opener installed in the US since 1993 is required to have safety reversal sensors mounted near the floor on each side of the door opening. These sensors beam an invisible signal across the door opening; if anything breaks that beam, the door won’t close (and in some cases won’t open from a stopped position).
Check each sensor for a solid indicator light. One should be green, one amber. A blinking or absent light means the sensors are misaligned, dirty, or have a wiring issue. Wipe each lens clean with a dry cloth and make sure neither sensor has been bumped out of alignment. Realigning sensors is often a two-minute fix. Our guide to garage door repair services covers sensor alignment as part of our full repair menu.
Every garage door opener has a red emergency release cord hanging from the trolley on the drive rail. Pulling this cord disconnects the door from the opener so you can operate it manually. With the door disconnected, try lifting it by hand.
If the door lifts smoothly and stays up on its own, the problem is with the opener, not the door itself. If the door is extremely heavy, won’t stay up, or drops when you let go, that’s a sign of a broken spring, which is a job for a certified technician. A door with a failed spring should not be operated manually; the spring carries most of the door’s weight.
Some garage doors have a manual slide lock or a vacation lock mode on the opener that disables the remote signal. If someone in your household activated vacation lock (sometimes called “lock mode” on LiftMaster and Chamberlain openers), the remote won’t work until it’s disabled. Check your opener’s manual or the button panel on the wall unit for a lock indicator light.
With the door in its current position, look along both vertical track sections. Are the rollers seated inside the track? Is there any visible bend or gap in the track? A roller that has jumped the track, even partially, will prevent the door from moving and can damage the system further if forced. If you see a roller outside the track or a visibly bent section, stop and call a technician. This is not a safe DIY repair.

The most common causes are a dead remote battery, a tripped circuit breaker, activated vacation/lock mode on the opener, or misaligned safety sensors. If those check out fine, the issue may be mechanical, like a broken spring, a stripped drive gear, or a derailed door. Run through the seven checks in this guide before calling; many sudden failures have a simple explanation.
Unplug the opener from its ceiling outlet, wait 30 seconds, and plug it back in. This performs a soft reset of the logic board and clears minor error states on most LiftMaster, Chamberlain, and Genie units. If the opener has a “Learn” button, you may need to re-pair your remotes after a reset. Check your model’s manual for the re-pairing sequence.
If pressing the wall button produces a click or motor sound but no door movement, the trolley or drive gear may be stripped. The motor runs but doesn’t transfer power to the drive rail. If pressing the button produces nothing at all, check power to the unit and the wall button wiring. If the door moves briefly and then reverses, the safety sensors or the opener’s force settings need adjustment.
