DoorKing gate motor repair in Henderson typically runs $225 to $485 for most board, limit switch, and arm failures, with same-week scheduling available and many repairs completed in a single visit. We’re an independent DoorKing service provider, not a factory shop, which means we diagnose the actual fault before recommending any parts swap. If you own a DoorKing 9150 slide operator, a 6002 swing arm, or an older 6003, you’re on the right page.

This page is for Henderson homeowners whose DoorKing opener has stopped behaving. The gate might open but not close. The motor might hum without moving. The keypad might work while the remote doesn’t. Call (775) 307-6571 and a live person answers, 24 hours a day. We’ll ask what it’s doing wrong, then tell you what it needs. Usually those are two different things.
How DoorKing Products Fail – and How We Fix Them
DoorKing builds commercial-grade operators that show up on plenty of Henderson residential properties, particularly in newer developments where developers spec’d slide gates. They’re durable, but they fail in predictable ways. Here’s what we see most often.
- 9150 slide operator limit switch drift. The 9150 uses mechanical limit switches that slowly walk out of position over hundreds of cycles. The symptom is a gate that stops a foot short of fully closed, or reverses before it should. The fix is resetting the limit cams and re-tensioning the drive chain. No parts needed on most calls, just labor and a proper adjustment. Some companies quote a control board for this. We don’t, because the board is usually fine.
- 6002 swing arm worm gear wear. The 6002 articulating arm has a worm gear inside the operator that takes the full load every time the gate swings. After five to eight years in Henderson heat, the grease thins and the gear teeth start to gall. The gate moves slower than it used to, then it starts groaning. This is a gear replacement job, and we use OEM DoorKing gears because the aftermarket versions are machined to looser tolerances and fail early.
- Control board relay failure on older 6003 units. The 6003 predates the current board design and runs relays that eventually weld themselves closed. The gate ignores commands, or it starts and won’t stop. A rebuilt board from an autoparts-style electronics shop might last a year. We prefer OEM DoorKing boards here, even though they cost more, because a welded relay that sends a gate into a locked position while a car is in the path is not a risk worth taking.
- Capacitor failure from Henderson summer heat. Every DoorKing operator has a start capacitor, and capacitors hate sustained heat. Henderson regularly sees 110°F-plus days in July and August, and the inside of a metal operator housing gets well past that. When the capacitor fails, the motor hums but won’t turn. It’s a straightforward replacement, and we carry the common DoorKing capacitor values on every truck so the repair happens in one trip.
- Loop detector false triggering on slide gates. DoorKing slide systems often pair with loop detectors buried in the driveway. When a loop detector fails, the gate either won’t open for a car sitting on it, or opens and closes randomly when nothing is there. Henderson’s clay-heavy soil shifts with moisture, which cracks loop wires over time. We test the detector first. If it’s the loop itself, that’s a saw-cut and splice job. If it’s the detector module, it’s a five-minute swap and a reset.
Styles & brands we work with




Our DoorKing Gate Motor Repair Process
Every job follows the same sequence, whether it’s a 9150 in Anthem or a 6002 near Raiders’ practice corridor. No shortcuts, no parts canon fired at the problem hoping something works.
- 1
You call, we answer. A live person picks up at (775) 307-6571. We ask about the symptoms, the model if you know it, and when the problem started. If the gate is stuck open or stuck closed with a car inside, we treat that as urgent.
- 2
We show up in a window we actually keep. Uniformed, background-checked technician. The van carries DoorKing-specific test gear and the common failure parts: capacitors, limit switches, loop detector modules, control boards for the 6002 and 9150 lines.
- 3
Diagnosis before parts. The technician tests the motor draw, the limit switch continuity, the board outputs, and the safety edges. Only after the fault is confirmed do we talk parts. And we tell you the price before we turn a single wrench if the repair goes beyond the diagnostic.
- 4
OEM parts where it matters, quality aftermarket where it doesn’t. Gears, boards, and safety components get OEM DoorKing parts. Capacitors, remotes, and loop detector modules are often fine with reputable aftermarket equivalents. We’ll explain the difference and the warranty on each.
- 5
Repair, then a full-cycle test. The gate cycles at least 15 times open and close, we check the safety reverse with a test obstruction, and we confirm the manual release works. Then we clean up the work area. Tools, wire clippings, grease smears, all gone.
- 6
Written guarantee before we leave. Every repair gets a written guarantee, good for a full year. If the same fault comes back inside that year, the second visit is free. That’s The Garrison Standard, and it’s in writing on every job.

AfterWhat DoorKing Gate Motor Repair Costs in Henderson
Here are honest ranges for the DoorKing jobs we do most in Henderson. The diagnostic visit is credited toward the repair, and you get the total price in writing before any work starts. The number doesn’t move at the door.
- Diagnostic service call: $49-$89, credited toward the repair if you approve the work
- Limit switch adjustment or replacement: $140-$260
- Start capacitor replacement: $120-$220
- Loop detector module replacement: $180-$320
- Control board replacement (6002/9150): $350-$550
- Worm gear replacement (6002 swing arm): $300-$485
- Full operator replacement (motor, board, arm): $1,100-$2,400 depending on model and site work
What moves the price: whether the operator is a swing or slide, how old the unit is, whether parts are still in production, and how much disassembly the job requires. A 6002 bolted to a brick column takes longer to work on than a 9150 on a clean steel post. Call (775) 307-6571 for a free estimate. The quote is free, the price is written, and it’s agreed before we start.

Why Henderson Homeowners Call Carver Gate Repair Henderson for DoorKing Work
We’re not the cheapest gate company in Henderson, and we’re not trying to be. We’re the one that answers the phone, shows up when we say, and puts the price in writing before the work starts. Lonnie Burke runs the Henderson team, and he’s the one who set the rule: diagnose first, sell parts second. His background in welding and metal fabrication comes in handy on DoorKing jobs where the operator is fine but the mounting bracket or gate frame has started to pull away.
Every technician is background-checked and uniformed. Every repair carries a 365-day written guarantee. If it fails inside a year, the return visit is free, no argument. We work on DoorKing every week, and we also service LiftMaster, Mighty Mule, and Ghost Controls, so if you have a second gate or a neighbor with a different system, one call covers it. The Garrison Standard has been the operating manual since 2008, and the guarantee is non-negotiable.
FAQs
We’re an independent DoorKing service provider, not a factory-authorized shop, so while we can’t submit claims under the manufacturer’s warranty, we can tell you whether the fault you’re seeing is a part that DoorKing typically covers and whether it’s worth contacting the original installer. Our own work carries a separate one-year written guarantee, so every repair we make is covered regardless of what the manufacturer does or doesn’t pay for.
Yes. We stock the common failure parts for the 9150, 6002, and 6003 lines on our Henderson trucks: capacitors, limit switches, control boards, and loop detector modules. For uncommon parts, we have direct relationships with multiple parts distributors and can usually have the component in hand within two to four business days. Call (775) 307-6571 and we’ll tell you if the part you need is on the truck right now.
If the motor is original and the operator is more than 12 years old, replacement often costs less over time than repeated repairs. The math is simple: a control board on an old 6003 might run $450, and six months later the motor could go. A new operator runs $1,100 to $2,400 with a fresh factory warranty and our one-year guarantee. Lonnie Burke will give you the straight answer on which path makes sense for your specific unit, and it’s generally based on motor condition, not the age on the label. Call (775) 307-6571 and we’ll walk you through it.
For a gate that’s stuck open or won’t close, we prioritize those calls and can often be on site the same day. For a gate that still works but is showing early symptoms, like slower operation or intermittent reverse, we typically schedule within two to four business days. The phone is answered by a live person around the clock, so you’ll know your exact window before you hang up.
We do both. If your existing DoorKing has failed beyond repair, we can source a new DoorKing operator, handle the full installation, and re-use any existing gate hardware that’s still sound. We also work with LiftMaster, Mighty Mule, and Ghost Controls if you want to compare options. The install includes testing, safety edge verification, and the same one-year written guarantee. Call (775) 307-6571 for a free measure and written price.
