Replacing a failed DoorKing gate motor in Woodland Hills typically runs $850 to $1,400 installed, depending on the model series and whether we replace the operator head alone or the full motor-and-gearbox assembly. We stock DoorKing-compatible motors, control boards, and limit-switch kits on our trucks, and we can usually complete the swap the same visit we diagnose the failure. Most owners call us after their gate has started moving slower than normal for a few weeks, then one morning it just won’t open, or it opens six inches and reverses. Sometimes it’s a locked rotor and a burning smell near the operator housing. Either way, the fix is usually a motor replacement rather than a rebuild, and we’ll show you the worn part before we pull it so you can see exactly what failed and why.
Which DoorKing Models This Applies To
DoorKing builds three main operator lines we regularly replace motors on in Woodland Hills: the 9000-series slide gate operators (9150, 9250, 9300), the 6000-series swing operators (6002, 6003, 6050), and the DFW/DSW heavy-duty commercial series for larger or higher-cycle gates. The motor is not universal across these lines. A 9150 slide motor won’t bolt into a 6002 swing housing even though both are DoorKing. Before we order or pull a motor, we read the model tag on the operator chassis, not the keypad or the control box. The tag plate on the motor itself will have the part number stamped into it, usually something like 26-2600 for older 9000-series motors or 26-2520 for the newer gear-reduced swing units. If the tag’s been painted over or weathered off, we pull the housing cover and measure the output shaft and gear stack. One real gotcha we see in Woodland Hills: owners buy a used or surplus DoorKing motor on eBay for a 9150, and it turns out to be a 120V motor from an old 9110, not the 24V motor the 9150’s controller actually drives. Then we’re out there anyway, replacing the board that got cooked. If you’re not certain of the part number, call us before you spend money on a part you can’t return.
On the OEM-versus-aftermarket question: DoorKing’s own replacement motors are well made and carry a known duty rating. Aftermarket drop-in motors exist for the 9000-series and some 6000-series operators. Some are fine. We’ve also seen aftermarket motors with windings that run hot in Woodland Hills’s August heat and fail within 14 months. We stock OEM DoorKing motors and a short list of aftermarket units we’ve personally verified against the 6000 and 9000 series. If a customer insists on the cheapest motor we can find, we’ll tell them plainly what we think the lifespan difference is and then install what they ask for. But our default, and our recommendation, is the proper DoorKing part for the DoorKing operator.
One thing worth knowing if your gate sits on high-cycle duty: the 9000-series and D-series operators are rated for different duty cycles. A residential 9150 running a long driveway gate in the Warner Center corridor that cycles forty times a day through a five-day workweek is being asked to do commercial-grade work. We see those motors burn out earlier than the spec sheet predicts, and we recommend a motor and gearbox rated for the cycle count, not just the cheapest drop-in replacement.
Styles & brands we work with





Signs Your DoorKing Gate Motor Replacement Is Failing
- Gate slows noticeably over a few weeks. The motor windings are losing torque, or the start capacitor is failing. A DoorKing operator should hold a consistent speed right up until the end. Gradual slowdown is almost always mechanical drag inside the motor or gearbox, not a setting.
- Gate starts, stops, and reverses before fully open. The motor’s drawing more current than the controller expects, and the board reads that as an obstruction. We check the limit switches and the leaf spring first, but if the motor’s pulling high amps, it’s the motor.
- Hum or buzz from the operator, but no movement. The motor rotor is locked or the start winding has failed. This is the classic sound of a DoorKing operator with a seized gear stack or a burned winding. Shut the breaker off until we get there.
- Burning smell near the operator housing. Varnish on the motor windings is cooking off. That’s heat damage, and it doesn’t heal. The motor needs replacement before it takes the controller board with it.
- Gate opens fine but drifts or slams closed. On swing operators, the motor’s internal brake or the gearbox’s holding torque has failed. The motor still spins, but it’s not holding the leaf in position. We see this most on 6000-series swing arms that have run for a decade without a gearbox service.

AfterReplacement Cost & What’s Included
In Woodland Hills, a DoorKing motor replacement with a Carver Gate Repair technician runs $850 to $1,400. The spread comes down to three things: which series motor you have, whether the gearbox or drive gear shows wear and needs replacement at the same time, and whether the controller board survived the motor failure. A 6002 swing motor alone, with labor and the motor, usually lands around $850 to $1,000. A full 9000-series motor, gearbox, and limit-switch kit with fresh drive chain tension on a Warner Center commercial gate can push toward $1,400. We don’t quote a vague “parts and labor” number into the air and then add to it later. The written price we hand you before we start includes the motor, the labor to swap it, the limit re-alignment, and the cycle test to confirm the gate opens and closes cleanly. If the board is also fried, we’ll put that on the written price as a separate line item so there’s no surprise when the work is done.
Every motor replacement we do carries our 365-Day Done Right Promise: a written guarantee on the repair, good for a full year from the date of service. If the motor acts up inside that year, we come back and fix it right at no charge. That’s what Lonnie Burke built the crew around, and it’s the non-negotiable standard for every job we roll out on in Woodland Hills.
DIY or Call Us?
There’s an honest split here, and I’ll give it to you straight: the things worth checking yourself are the breaker, the keypad or loop detector, and the manual release. If the breaker’s on, the keypad’s lit, the loops are clear, and the operator still won’t move, stop checking. DoorKing operators run on household voltage and the motor circuit carries real current even when the gate is idle. Opening the housing and probing around a live board kills the board, trips breakers, or lands you on your back. These motors sit inside cast housings with rotating gearsets that don’t care about fingers when the operator finally decides to move. The motor swap itself isn’t technically exotic for a person who’s done a few, but the limit re-alignment on a 9000-series slide gate is exacting, and a misaligned limit switch is how gates end up crushing the posts or the neighbor’s bumper a week later. If the motor needs replacing, call us at (650) 719-7207. We’ll put eyes on it, tell you the real number, and get it done without guessing.
FAQs
Eight to twelve years for a residential DoorKing motor in our climate, with two local caveats. Summer heat in the west San Fernando Valley pushes motor temperatures higher than coastal installs, which shortens winding life on units running twenty-plus cycles a day. And the clay soil here shifts; when a gate post drifts out of square, the motor loads up and dies early. If you’re running a slide gate on a long driveway in Woodland Hills and the motor dies at year six, check the post alignment before you just swap the motor. Call us at (650) 719-7207 and we’ll diagnose it correctly the first time.
Sometimes, but not often. A failed start capacitor is a twenty-minute fix. A worn brush or a sticking limit switch is serviceable. But if the windings are burned, the rotor’s locked, or the gear stack has chewed itself, rebuilding a DoorKing motor generally costs more in labor than a new motor, and the rebuilt unit won’t carry clean warranty coverage. We’ll always tell you which category your motor falls into before any money is spent.
Most residential DoorKing motor swaps take two to three hours on site. The motor and gearbox come out, the new unit goes in, the limit switches get re-aligned, the chain or arm tension is reset, and the gate is cycled a dozen times under load. If the controller board needs replacing too, add another hour. We schedule these as a single visit, not a “we’ll order the part and come back” job, unless the motor is an unusual commercial spec that isn’t on the truck. Call us at (650) 719-7207 and we’ll tell you what we can do today.
We do. Our Woodland Hills trucks carry 6000-series swing motors, 9000-series slide motors, limit switches, capacitors, and the common controller boards for the DoorKing line, plus equivalent parts for LiftMaster, Mighty Mule, and Ghost Controls operators. If you’re running a DFW-series or a higher-cycle commercial operator, we sometimes need a day to get the exact motor from our supplier. Either way, we answer the phone live, we give you a straight time frame, and we tell you the price before anything gets unbolted.
