FAAC Gate Motor & Opener in Sunnyvale: What to Know First

We provide independent FAAC gate motor and opener service in Sunnyvale, typically diagnosing and repairing most FAAC operators in a single visit. Most FAAC swing-arm and slide-gate motor repairs run $180-$340; full operator replacement with a comparable FAAC unit generally falls between $1,400 and $2,200 depending on the 400 series or 770 series model and whether the existing mounting bracket is reusable. We write the price before we pick up a tool, and we leave a photographed record of every adjustment.

Call (669) 900-1904

This page is for Sunnyvale homeowners who already know they have a FAAC operator and want to understand what’s actually wrong with it before calling anyone. If your FAAC 402, 422, or 746 is clicking without moving, reversing for no reason, or throwing a fault code you can’t clear, call (669) 900-1904. We’ll review what you’re seeing and schedule a technician who carries FAAC-specific parts.

How FAAC Products Fail - and How We Fix Them

• FAAC 400 series swing-arm operators - stripped worm gear in the reduction box. The 402 and 422 units use a brass worm gear that meshes with a steel worm. After roughly 8-12 years of daily cycles in Sunnyvale’s dry summers, the brass gear wears until the motor runs but the arm doesn’t move. We open the gearbox, measure gear backlash, and replace with OEM FAAC worm gear kits rather than aftermarket copies. The aftermarket gears we’ve tested run softer and fail again within 18 months.
• FAAC 746 slide-gate operators - limit switch drift causing overrun. The magnetic limit switches on 746 and 844 models lose calibration when the gate rail shifts slightly, which happens regularly near Sunnyvale’s older concrete driveways that heave in winter wet cycles. The motor hits the mechanical stop, the control board registers an obstruction fault, and the gate reverses. We reset limits with a digital protractor, photograph the final position, and note the rail condition in the job record so the next technician knows the history.
• FAAC control board capacitor failure - slow start or humming without torque. The start capacitors on pre-2018 FAAC 780 and 844 boards degrade in heat. Sunnyvale attic-mounted control boxes see 140°F+ in August. The capacitor tests within spec cold but drops microfarads under load. We load-test capacitors on-site rather than just checking voltage, and we carry replacement boards and discrete capacitor kits because FAAC doesn’t sell the capacitor separately for some revisions.
• FAAC hydraulic operators - seal hardening and fluid weep. The 400 series hydraulic units (402 SBS, 422 SBS) develop slow leaks at the cylinder seal after 6-10 years. The gate starts closing slower, then stops short on cold mornings. We rebuild the cylinder with FAAC seal kits or replace the entire hydraulic unit if the bore is scored. Rebuild saves roughly $400-$600 versus replacement, but only if the cylinder wall is clean.
• FAAC encoder disk contamination - erratic travel and false obstruction stops. The optical encoder disk inside 746 and 844 motors collects metallic dust from brush wear. The control board loses position tracking and defaults to safety mode. We disassemble the motor housing, clean the encoder with lint-free solvent wipes, and verify pulse count against factory spec before reassembly. Most gate techs replace the entire motor; we clean and test first because the encoder fix costs a fraction and lasts years.

Our FAAC Gate Motor & Opener Process

1. 1
   Call review. We ask for the FAAC model number from the operator label, the fault code or symptom, and whether the gate is stuck open or closed. This determines which parts the technician loads.
2. 2
   On-site diagnosis. The technician tests input voltage at the control board, checks limit switch continuity, and runs the operator in manual override mode to isolate mechanical versus electrical failure. Every reading is photographed.
3. 3
   Parts decision. If the part is available as genuine FAAC and the price difference from quality aftermarket is under 30%, we quote OEM. For discontinued 400 series components, we use aftermarket parts we have field-tested and document the substitution in writing.
4. 4
   Repair and calibration. We replace or rebuild, then recalibrate force settings, limit positions, and safety edge response per FAAC’s torque tables - not by feel. The settings are photographed and recorded.
5. 5
   Final test and documentation. We cycle the gate 20 times, test safety devices, and leave you with a written summary and photo log. Under Clause 4 of The Haven Standard, this documentation is included at no additional charge.
6. 6
   365-Day Done Right Promise activation. The repair is covered for one full year. If anything related to our work fails, we return and make it right at no charge.
