FAAC Gate Motor Replacement: The West Covina Owner’s Guide
Most FAAC gate motor replacements in West Covina run between $850 and $1,450 installed, depending on which FAAC series you have and whether your mounting hardware is still sound. We stock FAAC-compatible motors and carry common arm assemblies on the truck, so many replacements in West Covina can be completed the same day we diagnose the failure. The usual discovery path goes like this: the gate starts moving slower than it did last year, then one day it beeps without moving at all, or it opens halfway and stops dead.
What you’re looking at is almost never the gate itself. It’s the operator, the motor-and-gearbox unit inside the housing that has been cycling that gate every day since it was installed. FAAC builds solid equipment, but West Covina heat, dust from the foothills, and the constant load of a hillside driveway near Galster Wilderness Park all age a motor faster than flat-land service would.
Which FAAC Models This Applies To
We service and replace motors across the FAAC line: the 400 series swing operators (402, 412, 415, 422), the 750 and 760 series for heavier swing gates, the S450H and S700H hydraulic swing arms, and the C720/C721 sliding gate operators. Each series uses a different motor assembly, and the mounting plate bolt pattern is not interchangeable across series. That’s the compatibility gotcha we see most often in West Covina: a homeowner buys a used 402 motor to replace a dead 412, and the mounting holes don’t line up.
The reliable way to identify what you have is to read the silver data plate on the operator housing. It lists the model number, voltage (120V or 24V), and the serial number, which contains the production year. If the plate is gone or painted over, we match by housing dimensions and arm length. FAAC’s 400-series motors are 24V DC with an encoder for soft-start and soft-stop; the 750-series adds a hydraulic circuit that costs more to replace but handles continuous-duty cycling that the smaller 400s were never built for.
Signs Your FAAC Gate Motor Replacement Is Failing

- Gate moves noticeably slower in one direction. The motor’s capacitor or winding is degrading, and it’s working harder to open than to close (or vice versa). This is the earliest warning you’ll get, and it can run for months before full failure.
- Motor hums but the gate doesn’t move. The start capacitor has failed, or the gearbox has stripped a tooth. A hum-and-no-move is usually a capacitor on FAAC 400s, and a mechanical bind on the hydraulic 750s.
- Gate stops mid-cycle and reverses or faults out. The encoder is sending bad position data, which makes the control board think the gate hit an obstruction. On FAAC motors, the encoder is integrated into the motor assembly, so the fix is a motor replacement, not a board reset.
- Burning smell or heat radiating from the housing after a cycle. Winding insulation is breaking down. This is the one to act on immediately; a motor that’s hot enough to smell is close to shorting and can take the control board with it.
- Intermittent operation that gets worse after rain or heavy dew. Moisture has entered the housing through a failed gasket, common on older West Covina installs where the marine-layer mornings in the foothills keep seals damp for hours.

AfterReplacement Cost & What’s Included
For most FAAC swing motors in West Covina, plan on $850 to $1,450 installed. The range breaks down like this: a 400-series motor assembly runs $425 to $620 for the part, a 750-series hydraulic motor runs $700 to $950, and labor for a straight swap runs $300 to $450. If your arm bracket, mounting plate, or limit-switch assembly is rusted or out of square, expect $120 to $280 in additional hardware.
You get the written price before we open the housing. That’s Haven Standard Clause 1, and it applies to every FAAC motor replacement we do in West Covina. The written quote includes the exact part number we’re installing, the labor flat rate, and the disposal of the old motor. Every replacement carries the 365-Day Done Right Promise: if the motor or our work fails within a year, we fix it at no charge. No argument, no invoice.
DIY or Call Us?

There’s a safe middle ground between doing nothing and doing surgery. You can check the obvious things: is the operator getting power, is the manual release lever engaged, is there debris in the gate track or arc? What you should not do is open a FAAC motor housing and start disconnecting the capacitor or encoder wiring. These units carry stored charge even with the breaker off, and the encoder calibration on the 400 series is done with the motor under load. Get the calibration wrong and the gate will slam through its travel arc.
If you’ve already done the safe checks and the motor still won’t cycle, call us at (562) 368-4485. We’ll give you a straight answer over the phone, and if a diagnostic visit makes sense, you’ll get a written price before any work is approved. No surprise invoice at the end, ever.
FAQs
A properly maintained FAAC motor in West Covina typically lasts 8 to 12 years, with hillside driveway loads and full-sun exposure shaving the useful life down 2 to 3 years compared to a shaded flat-land install. Capacitors and limit switches usually fail first, before the motor windings themselves. Call (562) 368-4485 if your motor is older than a decade and starting to misbehave; a replacement usually costs less than a third repair cycle on the same unit.
Sometimes: external capacitors, limit-switch assemblies, and arm brackets are the repairs we can do cheaply and reliably. But once the encoder, the windings, or the gearbox fails internally, the motor is a sealed assembly and the honest fix is replacement. We’ll always tell you which one you have and put it in writing before any work starts.
Most FAAC swing-motor replacements in West Covina take 90 minutes to 3 hours, including removal of the old unit, mounting alignment, encoder calibration, and a full cycle test under load. If the arm bracket or mounting plate needs rework, add an hour. We’ll tell you the window before we start and leave you the photo log when we’re done.
We stock FAAC 400-series motors, common arm assemblies, capacitors, and limit-switch kits on the truck, which is why many West Covina replacements happen same-day. For 750-series hydraulic units and less-common sliding operators, we order from the same distributor and typically install within 3 to 5 business days. We’ll tell you which bucket your motor falls into on the first call.
If your FAAC gate motor is dead or dying in West Covina, call (562) 368-4485 for a written estimate and a same-day or next-day replacement. We also stock parts for LiftMaster, Mighty Mule, and Ghost Controls operators if your neighbor’s gate is the one acting up. A live person answers, any hour.
