A DoorKing gate motor replacement in Fort Lauderdale typically runs $380 to $850 installed, with most residential swaps landing in the $450 to $650 range for the motor itself, labor, and calibration. We stock DoorKing-compatible motors and gear assemblies on our trucks for the models most common in Broward County, so the job is usually same-day or next-morning once we confirm which series you have. What most owners notice first is the gate going dead silent when they hit the clicker, or a motor that hums but can’t move the gate an inch. Sometimes the chain whips around while the gate itself barely budges. By the time you’re searching for this page, you’ve probably already given the board a suspicious look and the battery a courtesy tap. The motor is usually what’s left.
Which DoorKing Models This Applies To
DoorKing has been building slide-gate operators out of Inglewood, California since 1948, and their residential workhorses in Fort Lauderdale are the 9050, 9100, and 9150 series sliding gate operators, plus the 6002 and 6003 swing gate operators you see on older Coral Ridge and Rio Vista driveways. The 9150 replaced the 9100 around 2009, and while the motors look similar from the outside, the gear ratios changed and the capacitor values differ. Here’s the gotcha that matters: putting a 9100 motor into a 9150 chassis will bolt up fine and then chew the gearbox to pieces within a season. The model plate on the side of the operator cabinet tells you the series, and there’s a smaller motor tag riveted to the motor body with the part number. That motor tag is what we ask for when you call.
DoorKing OEM motors are built to spec and carry predictable tolerances. There are also quality aftermarket equivalents, which is a polite way of saying some are good, some are fine, and some are the reason the phrase “warranty denial” exists. We install whichever makes sense for your gate’s age and daily cycle count, and we tell you which one we’re quoting and why. We’re not affiliated with DoorKing, but we’ve serviced enough of their operators across Broward that our techs know the series quirks without having to puzzle through a parts diagram on your driveway.

Signs Your DoorKing Gate Motor Replacement Is Failing
- Gate hums but doesn’t roll or swing. The motor is getting power and trying to spin, but the gear train or belt has slipped. If you hear the hum and see zero movement, that’s a stripped gear or a dead drive belt loading the motor to its limit.
- Gate moves in jerks or stutters forward a few inches, then stops. The capacitor is failing. On DoorKing slide operators, the capacitor is what gives the motor its starting torque, and a weak one feels exactly like a half-dead battery in a car that still clicks.
- The motor runs, but the gate won’t hold closed. In Fort Lauderdale, this is usually the limit switches or the internal clutch wearing out. The motor spins, the gate drifts, and the operator thinks it closed all the way. Your security gap is a real one, not a cosmetic one.
- Burning-smell after heavy rain or a storm. Salt air and humidity work on the windings. A motor that spent years breathing Fort Lauderdale coastal air eventually lets the corrosion win, and the first sign is a hot electrical smell when the gate cycles during a downpour.
- Gate ran fine for years, now moves at half speed. Worn brushes and commutator wear in the motor itself. This is the slow decline, not the sudden death, and it’s cheaper to address before the motor seizes and takes the gearbox with it.

AfterReplacement Cost & What’s Included
For a standard DoorKing slide gate motor swap in Fort Lauderdale, you’re looking at $380 to $550 for most 9050 and 9150-series motors with labor included. The larger 9100-series and heavier swing gate motors run $500 to $750, and if the gearbox or drive belt needs replacing at the same time, that makes up the upper end. Parts and labor aren’t split into mystery line items; you get the motor price, the labor price, and any hardware we can see you’ll need in advance. The written price we quote is the price on the invoice, no discoveries, no additions. The replacement carries our 365-Day Done Right Promise in writing. If the repair fails within that year, we’re back out at no charge, and that trip is free too. Every Portcullis Gate Repair location is independently owned, but the Kingswell Guarantee is the same written promise on every job: a written price, a real arrival window, a clean job site, and a written guarantee on the repair.
DIY or Call Us?
For door operators, the safe and honest line is this: you can absolutely change the capacitor, check the belt tension, and clean the limit switch contacts if you’re comfortable with a meter. DoorKing operators use 115V or 208/230V supply current depending on the model, and the inrush current on a slide gate motor is enough to hurt you. If you’re swapping a motor, the operator cabinet has wiring that stays live even with the main disconnected because of the battery backup units we strongly recommend for Fort Lauderdale’s storm season, and that battery bank will back-feed the board. Give us a call at (754) 354-7351 before you take the cover off. We’ll tell you over the phone whether it’s a capacitor you can handle in ten minutes or a motor swap that’s safer in uniformed hands. A written price first, then the work – that’s how we do it. It applies to the small jobs and the full motor replacements, every time.
FAQs
In Broward’s heat and salt air, a DoorKing slide gate motor typically lasts 7 to 10 years on a residential gate that cycles 10 to 15 times a day. Coastal properties along the Intracoastal or within a mile of the ocean tend to run closer to 6 or 7 years because the salt mist gets into the windings. A motor under a proper cover with a functioning battery backup will almost always outlast one in direct sun and standing rainwater. Call (754) 354-7351 and we can tell you if yours is at the expected end of life or died young for a fixable reason.
Sometimes, but not as often as people hope. A bad capacitor, worn brushes, or a corroded connection can be repaired for under $200 in Fort Lauderdale. Burned windings, a seized bearing, or a stripped gearbox usually costs more to rebuild than to swap in a new motor with a written 365-day guarantee. We’ll tell you which category yours falls into before you spend a dollar.
Most residential DoorKing motor replacements in Fort Lauderdale take 60 to 90 minutes once we’re on site, assuming the gearbox and belt are still healthy. If the gate needs re-hanging, the gearbox is worn, or the board has to be reprogrammed, that’s 2 to 3 hours total. We’ll give you a real arrival window when you book, not a four-hour open span, and it’s on the written quote.
We keep DoorKing motors, capacitors, belts, and limit switches on the truck for the 9050, 9100, and 9150 slide operators, plus the 6002 and 6003 swing gate motors. If you have a less common DoorKing model or a commercial operator, we source it same-day from our supply partners in Fort Lauderdale, and we’ll also quote you the aftermarket equivalent so you’re not staring at the ceiling waiting for the brown truck.
