How to Solve Garage Door Opener Failure?

A garage door opener is a motorized device that opens and closes a garage door controlled by switches on the garage wall. It is common equipment in homes and factories. This article will introduce specific measures when garage door opener fails.

If the light does not come on, check the fuse box or circuit breaker. Are all doors unlocked? Re-read the installation instructions warnings. Is there ice or snow under the door? The door may have frozen to the ground. Clear obstacles. The garage door spring may have broken. Ask a professional to replace it.

If the garage door operator operates, check the door control panel for wiring errors, shorts under the staples, or broken wires. Are all wire connections good? Read the installation instructions again.
