A Linear gate motor replacement in West Covina typically runs $650 to $1,400 installed, depending on the model and whether the arm, control board, or the whole operator needs to go. We stock Linear-compatible operators and parts on our trucks and can usually have a technician at your property the same day you call. Most owners figure out the motor has failed when the gate simply stops responding to remotes, or when it groans, jerks, and trips the breaker mid-cycle.

Linear builds solid equipment, but nothing lasts forever in West Covina’s heat. Capacitors dry out, gear teeth strip, and control boards cook in the sun. When that happens, you need a straight answer on what it costs and who can actually do the work right the first time. That’s what this page is for.
Key takeaways:
- Installed Linear gate motor replacement in West Covina: $650 to $1,400, with most jobs landing between $850 and $1,100.
- We quote a written price before any work starts. The number does not change once the job is open.
- Every repair carries a 365-day written guarantee through The Garrison Standard. If it fails inside a year, we return free.
- Lonnie Burke and our crew have serviced Linear operators across West Covina for more than a decade, including repeat work near South Hills Country Club.
Which Linear Models This Applies To
If your Linear gate operator is from the LRA, LSO, LD, or APeX series, this page covers what you need to know. The most common Linear residential swing operators in West Covina are the Linear LRA-S and the Linear LSO line. Slide gates usually run a Linear SL or M-series. Each of these takes a specific motor assembly, and the part numbers are not interchangeable across series even when the motor housing looks close.
The fastest way to identify what you have is to open the operator’s plastic cover and read the model label on the control board or the chassis. Older Linear units have that label stamped near the power input. If the label is faded or gone, measure the output shaft and count the gear teeth, or take a clear photo of the board and send it to us. We match the part by the board revision, not just the model name, because Linear changed internal components mid-production on several LRA models. In our area, one of the most common mismatches we see is a homeowner buying an APeX-series arm for an LRA operator. The mounting points and shaft length differ, and forcing it strips the coupler inside the first month. We stock both OEM Linear and quality aftermarket equivalents, and we’ll tell you honestly when the aftermarket part is the better value and when it isn’t.

Signs Your Linear Gate Motor Replacement Is Failing
Symptoms don’t show up by accident. They’re the motor telling you something specific.
- Gate won’t open or opens halfway. This usually points to a motor capacitor that has lost its charge or a stripped gear inside the reduction drive. In West Covina’s summer heat, capacitors fail more often than any other single component.
- Humming or buzzing with no movement. You’re hearing the motor trying to turn against a seized gear train or a bound axle. Do not keep pressing the remote. Repeated tries cook the windings and turn a gear-level repair into a full operator replacement.
- Gate moves slower than it used to. Worn brushes, dragging gears, or low voltage to the motor. Linear operators are rated for a specific duty cycle, and older units that run dozens of cycles daily will naturally lose speed as the brushes wear. Expect a properly maintained Linear operator in West Covina to last 8 to 12 years before the motor itself gives out.
- Burning smell from the operator box. Insulation on the motor windings is breaking down. This is an immediate stop-and-unplug situation. We’ve opened more than one Linear box in West Covina where the owner kept using the gate after smelling hot plastic, and the board was burned past repair by the time we got there.
- Breaker trips when the gate runs. A grounded winding or a failing start capacitor pulling too much current. This will only get worse, and it can damage the control board before the motor finally stalls.
Replacement Cost & What’s Included
For most residential Linear operators in West Covina, an installed motor or full operator replacement lands between $650 and $1,400. The range depends on what actually failed, whether you have a swing or a slide gate, and whether the old operator is still on a supported Linear platform. A motor-only swap on an LRA-S swing unit with good existing arms usually stays under $850. A full operator replacement on a slide gate with new chain brackets, limit adjustments, and safety loop wiring checks will push toward the high end, and if we’re replacing the arms, the photo eyes, and the keypad at the same time, expect $1,600 to $2,200 for a complete refresh.
Every quote is written and itemized before we open a single panel. You’ll see the part cost, labor, and any additional hardware as separate numbers, and you agree to that number before any work starts. The price never grows once the job is open. That’s how we’ve run since 2008 under The Garrison Standard, and it’s non-negotiable. Every Linear gate motor replacement carries our 365-day Done Right Promise in writing. What that means in practice: if the motor we install fails within one year, we come back and make it right at no charge, no argument.

You can safely inspect a few things without opening the operator. Check the breaker. Verify the unit is plugged in. Send a photo of the model label. But opening a Linear gate operator and swapping a motor, capacitor, or board is not a weekend project. These boxes carry live 120V wiring, and the control board holds a stored charge that will bite even with the breaker off. The gate either works right or it doesn’t and there’s not much in between. A wrong capacitor value, a reversed wire, or a limit switch set too far will trash a brand-new board in one cycle. We’ve followed enough owner-attempted repairs in West Covina to know that a $40 part swap turns into a $900 board replacement more often than anyone wants to admit. If you’ve already opened it and aren’t sure what you’re looking at, stop. Call (925) 268-7956 and describe what you see. We’ll tell you over the phone if it’s something simple.
FAQs
A Linear gate motor on a residential gate in West Covina typically lasts 8 to 12 years with average use. Coastal-adjacent humidity and summer heat cycles shorten that when the operator is metal-housed and sun-facing all afternoon. We replace more Linear motors that failed from heat stress on capacitor and winding failures than from mechanical wear, and aftermarket motors with higher-temp insulation tend to hold up better in the San Gabriel Valley climate.
Sometimes. Worn brushes, a bad capacitor, or a seized bearing can be replaced without a full motor swap, and we’ll always quote the smaller repair first if it makes sense. But if the windings are burned, the commutator is scored, or the gearbox shaft is scored, the repair won’t outlast the labor that went into it. Call (925) 268-7956 and we’ll tell you which side of that line your motor is on after a diagnostic.
On a swing gate with an intact arm system, we replace a Linear motor in about one to two hours on site. A full operator replacement with new arms, photo eyes, and limit setup runs three to four hours. Add another hour if we’re also installing a new keypad or adjusting the loop detector. Most West Covina jobs are done in a single visit.
We stock Linear-compatible motors, capacitors, control boards, and arm assemblies for the most common LRA, LSO, and M-series units, and we carry quality aftermarket equivalents for out-of-production Linear models. If your unit needs a part we don’t have that day, we’ll have it ordered and scheduled within the week, and we’ll tell you that before you pay for the diagnostic.
