Garage Door Won’t Open? Here’s What to Check Safely
Understand common reasons a garage door stops working and when to call for help.
First, decide whether to stop
If the door is crooked, a cable looks damaged or a spring appears separated, stop operating it and keep the area clear. Do not pull the emergency release on an open or damaged door. Do not try to lift it to see whether it is heavy.
Describe what you can observe safely
From a safe position, note whether the opener has an indicator light, whether you hear a sound when a control is used, and whether one control behaves differently from another. Consult the opener manual for its indicator meanings. Do not repeatedly cycle a struggling door.
What to tell a technician
Explain when the problem started, whether the door is open or closed, and whether there was a bang, impact or power outage. Include the brand or model only if you can read it safely. You do not need to diagnose the fault before asking for help.
Choose the next step
If you cannot identify a simple control issue from your manual, arrange an assessment. Never bypass a safety device or adjust springs, cables or brackets. A description of the symptoms is enough to start a repair conversation.
