Automatic Door Repair in Southern California

Automatic pedestrian doors involve drive motors, control boards, presence detectors, safety sensors, and safety zone logic that must all function together correctly. A fault in any one component can make the door unsafe or non-compliant with ANSI/BHMA A156.10 — the governing safety standard for power-operated pedestrian doors. Diagnosing and repairing these systems requires specific experience with automatic door technology that goes beyond standard door service.

ANSI/BHMA A156.10 covers kinetic energy limits during operation, presence detection that prevents the door from closing on a person, safety zone coverage, breakout panel emergency egress function, and required warning signage. Non-compliant automatic doors create ADA and insurance liability exposure for your facility.

For emergency automatic door failures, we target same-day response across Southern California — dispatching from our Yorba Linda base. Most commercial locations in the Inland Empire and Orange County are within 20-40 minutes.

Yes. We service all major automatic door brands including ASSA ABLOY, Besam, Stanley, Hormann, Dorma, Tormax, Nabco, Overhead Door, CR Laurence, and LCN — as well as other brands found in commercial and institutional facilities.

Yes. After every service visit, your facility receives a written service report documenting the condition of the system, work performed, parts replaced, and any deficiencies found — including compliance notes relevant to ANSI/BHMA A156.10 requirements.

Cost depends on the failure mode, brand, and parts required. A typical diagnostic and minor sensor, belt, or safety adjustment visit is less expensive than control board or drive motor replacement. We provide an upfront quote before starting work, and we stock common automatic door parts on our service vehicles to keep repairs same-day when possible.

Common causes include a failed or misaligned presence detector, a worn drive belt, a faulty control board, low power to the operator, or a safety sensor that thinks an obstacle is present. Our technicians diagnose the root cause with the correct test equipment and replace only the parts that actually failed.

High-traffic automatic doors should be inspected and adjusted at least once per year, with quarterly checks for very heavy-use entrances. Preventive maintenance extends operator life, reduces emergency calls, and keeps the door within ANSI/BHMA A156.10 safety limits.

• Won't open — dirty or misaligned sensors, power, or control board; cleaning, calibration, testing.
• Stays open after opening — drive, lock, or track obstruction; inspection and clearing.
• Doesn't reverse on contact with people or objects — failed safety sensor (safety-critical: unit taken out of service, sensor replacement, ANSI/BHMA A156.10 testing).
• Slow or noisy operation — worn belts, rollers, motors; wear-part replacement.
