Is Your Opener
Humming But Not Moving?
We repair all major motor brands and install smart openers that let you control your garage from anywhere in Pasadena.
Grinding Noise
The Diagnosis: Likely a stripped main gear inside the motor housing. Common in older LiftMaster units.
Blinking Lights
The Diagnosis: Safety sensors are misaligned. If the light blinks 10 times, the beam is blocked or broken.
Remote Not Working
The Diagnosis: Logic board failure or signal interference (LED bulbs).
Is It Just Misaligned Sensors?
Save a service call fee by checking these 3 things first.
Clean the Lens
Spiderwebs or dust on the little glass eye can break the beam. Wipe both sensors with a dry cloth.
Check the Lights
One sensor should have a solid Green light, the other Amber. If one is blinking, they are not looking at each other.
The "Wiggle" Test
Loosen the wing nut and gently wiggle the sensor until the blinking light turns solid. Then tighten it.

Opener Tech Support
My opener is beeping. What does it mean?
If your opener has a Battery Backup, a beeping sound usually indicates the battery is low and needs replacement. This is common in California due to SB 969 compliance. We stock replacement batteries for all LiftMaster units.
Can you program my car's Homelink system?
Yes. Our technicians can assist in programming your vehicle's Homelink buttons to work with your new garage door opener during the installation visit.
Why is my garage door opener making a grinding noise?
In Pasadena, the most common cause of a grinding noise in garage door openers is a stripped drive gear. This often happens due to age or a heavy, unbalanced door. Our Pasadena technicians specialize in gear kit replacements for LiftMaster and Chamberlain models.
