Garage Door Symptom Checker in Fairfield, IA

Likely causes:

• Broken torsion or extension spring
• Opener has no power or the lock mode is on
• Snapped or slipped lift cable
• Stripped opener gear

Safe checks:

• Look for a gap in the spring above the door.
• Check that the opener is plugged in and the wall button lights up.
• Turn off the lock or vacation mode on the wall control.
• Replace the remote battery.

When to call: Call if a spring or cable is broken or the opener hums without moving the door. See the service

Likely causes:

• Photo-eye sensors misaligned, dirty or blocked

• Door too heavy because of a weak spring

Safe checks:

• Wipe the sensor lenses and make sure both lights are steady.
• Clear anything in the door's path.
• Hold the wall button down until the door closes. If that works, it's almost always the sensors.

Likely causes:

• Broken spring making the door too heavy
