Garage door won’t open? Start here.
A garage door that won’t open can be caused by anything from a flat remote battery to a broken spring. Here’s what homeowners should check before assuming the worst.
Most problems are simpler than they look.
If your garage door won’t open, the cause is often a flat battery, a remote issue, a power interruption or a safety system fault.
More serious problems such as broken springs, snapped cables or motor failures are less common but do occur.
Four quick checks.
Power
Check whether the opener has power and whether the circuit breaker has tripped.
Remote
Replace the battery or try a second remote if available.
Wall Control
Test the wall button to determine whether the issue is with the remote or opener.
Lock Mode
Some systems have a lock or vacation mode that disables remote operation.
What we see most often.
The most common causes behind a garage door that won’t open.

When to stop troubleshooting.
If the garage door feels unusually heavy, has a broken spring, damaged cable or appears off its tracks, stop operating it immediately.
Garage doors are under significant spring tension and attempting repairs without the correct tools can be dangerous.
When in doubt, disconnect the opener and have the system inspected before further use.
“If the door feels heavy or something looks out of place, leave it alone and call us. A quick inspection is always safer than forcing a door under tension.”
