Opener repair across Marin
All Marin townsOpener questions
Opener runs, door doesn't move?Is it worth repairing my garage door opener?
Usually, when the unit is under about ten years old and the fault is a gear, a board, the limits or the sensors. Chen Garage Door repairs openers in San Rafael and across Marin from $185. When a repair costs close to a new opener, from $620 installed, you get both prices before you choose.
Why does my opener light blink when the door won't close?
The safety sensors. The blinking means the beam between the two photo eyes is broken. Clear the path, wipe both lenses, and check that both sensor lights are steady. If one stays off, it is out of line or its wire has failed.
Do you work on every brand?
We work on the common residential brands, and gear kits, boards and sensors are made for nearly all of them. When an older unit's parts are no longer made, we say so at the visit and price a new opener.
