A DoorKing gate motor replacement in Henderson typically runs $850 to $1,650 installed, depending on whether you need a swing-arm operator or a slide-gate motor. We stock DoorKing-compatible motors and control boards on our trucks, and most replacements are done the same day we diagnose the failure. If your gate has started groaning, stalling mid-travel, or refusing to open after a hot Vegas afternoon, the motor is usually the culprit.
Most Henderson homeowners discover the motor has failed when the gate works poorly in the morning, gives up entirely by noon, and the manual release handle has become a permanent fixture on their daily routine. The desert heat doesn’t create these failures, but it does accelerate them, and once a DoorKing motor starts drawing high amperage against a tired gearbox, the clock is running.
Which DoorKing Models This Applies To
DoorKing builds two main lines that show up in Henderson driveways: the 6000/6100 series slide-gate operators and the 9000 series swing-gate operators. Within those lines, you’ll see model numbers like the 6050, 6100, 6500, 9050, and 9100. The slide operators use a 1/2 HP motor with a chain-driven gear reduction, while the swing operators are either direct-drive or use a belt reduction depending on the exact model year.
The fastest way to identify your motor is to open the operator cover and look at the metal tag riveted to the motor housing. It’ll list the part number, voltage (115V or 208/230V), and serial date code. Don’t guess off the operator model alone; DoorKing has shipped at least three motor revisions in the 6000 series, and the mounting-bolt pattern changed between revisions. We carry OEM DoorKing motors plus quality aftermarket equivalents that match the OEM specs exactly. For most homeowners, the aftermarket unit is indistinguishable in daily use and runs $200 to $350 less. We’re an independent service company, not a DoorKing dealer, so we’re free to tell you when the aftermarket part is the better buy and when it isn’t.

Signs Your DoorKing Gate Motor Replacement Is Failing
- Gate hesitates or stalls halfway through travel. This usually means the motor’s thermal overload is tripping because it’s drawing too much amperage, either from a failing capacitor or worn gearbox bearings. Once it starts tripping, it’ll only get more frequent until the motor locks up.
- You can hear the motor humming but the gate doesn’t move. The start capacitor has failed. A cheap part by itself, but on DoorKing 6000-series operators, the capacitor failure often precedes full motor failure by a few months because the motor has been struggling to start under load.
- Burning smell from the operator box. The motor windings are overheating. This is the point where continued use turns a motor replacement into a motor plus control board replacement, which doubles the job.
- Gate has lost power or gets slower over weeks. Motor brushes (on older units) or degraded magnet strength means the motor is producing less torque than the control board expects. The board compensates by running the motor longer, which accelerates wear.
- Breaker keeps tripping when the gate cycles. A shorted motor winding is drawing more current than the circuit can handle. This one is electrical, not mechanical, and needs a motor swap before it stresses the control board.
Replacement Cost & What’s Included
In Henderson, a full DoorKing motor replacement runs:
- Slide-gate operator motor (6000/6100 series): $425 to $675 for the part, $250 to $400 for labor and setup
- Swing-gate operator motor (9000 series): $500 to $850 for the part, $300 to $450 for labor and setup
- Control board replacement (if the motor took it out): $350 to $600 additional
Every quote includes the new motor, removal of the old unit, mounting, chain or belt re-tensioning, limit switch setting, and a full cycle test. You get the written price before we start, and the number doesn’t move when the job is open. The Garrison Standard is our operating code: a written guarantee on every repair, good for a full year, and if it fails inside that window we return free of charge.

You can safely check a few things yourself: confirm the breaker isn’t tripped, confirm the gate hasn’t come off its track, and check that the manual release handle isn’t in the released position. Those three account for a surprising number of “dead gate” calls we take in Henderson.
Beyond that, don’t open the operator housing. These are 115V or 230V systems with capacitors that store charge even after power is cut. A capacitor discharging through a screwdriver is the kind of lesson you only learn once. And if the motor did fail, the replacement is not a pull-and-swap: the limit switch timing, chain tension, and travel stops all need to be dialed in for your gate’s exact length and weight. Get it wrong and the new motor dies young. Call us at (775) 307-6571 and tell us what the gate is doing wrong. Lonnie Burke has been doing this long enough to know that what it’s doing wrong and what it needs are usually two different things.
FAQs
A well-maintained DoorKing gate motor lasts 8 to 12 years in Henderson’s climate, though the heat and dust out here tend to shorten that to 6 to 8 years on gates that run more than 20 cycles a day. The gearbox usually outlives the motor, which is why the motor alone, not the whole operator, is what most homeowners replace. Call (775) 307-6571 and we’ll tell you if your motor is repairable or past saving.
Sometimes. The start capacitor, limit switches, and motor brushes (on older units) are all replaceable parts that cost under $100 each. If the motor windings are burned or the motor is drawing high amperage with nothing mechanically binding, replacement is the honest answer. We don’t sell motors to people who only need a capacitor.
Most DoorKing motor replacements in Henderson take 2 to 3 hours from arrival to final cycle test. Jobs that include a control board replacement add about 45 minutes. We stock the common DoorKing motors on our trucks, so we usually don’t need a second visit.
We stock DoorKing 6000-series slide motors, 9000-series swing motors, control boards, and capacitors on our Henderson trucks. LiftMaster, Mighty Mule, and Ghost Controls parts are also on hand. If we don’t have your exact revision, we’ll have it within one business day.
