An electric gate that won’t open, won’t close, or grinds halfway and stops isn’t a minor annoyance. It cuts off your driveway, blocks deliveries, and leaves your property either exposed or trapped. We fix that. Ontario Gate Company handles electric gate repair in Ontario, CA as our core trade, not a side service. Our technicians arrive with brand-specific diagnostic equipment and parts for LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule systems. Call (855) 707-3634 and we’ll get a technician out to diagnose your gate on-site.
Gate Opener Repair
Gate opener repair is the most common call we run in Ontario. Your opener is the motorized unit that pulls or pushes the gate leaf, and when it fails, the gate becomes dead weight. We see opener failures from worn gears, burned capacitors, failed limit switches, and control board shorts. On-site diagnosis tells us which part failed and why, so we replace the failed component rather than guessing and swapping parts. A typical gate opener repair in Ontario runs $180 to $480 depending on whether it’s a gear kit, capacitor, limit switch, or board replacement.
Opener Diagnosis and Replacement
We test voltage to the motor, check gear wear, and verify limit switch function before recommending any repair. That keeps the fix targeted. When a repair won’t hold, we quote a full opener replacement with the same brand or a compatible upgrade.
Common Opener Failures
Gear stripping tops the list, especially on older LiftMaster and Elite units that have run for a decade. Failed capacitors come second on residential swing gates. We keep common gear kits and capacitors stocked for the brands we service so most opener repairs finish in one visit.
Styles & brands we work with





Automatic Gate Repair
Automatic gate repair covers the full system that opens and closes your gate without manual effort: the operator, the safety sensors, the receiver, and the wiring between them. When any one part fails, the whole gate misbehaves. We diagnose the entire system, not just the obvious symptom. That’s the difference between a fix that holds and a repair that fails again in three weeks. Automatic gate repair in Ontario typically falls between $150 and $600, depending on whether we’re replacing a sensor pair, a receiver, a transformer, or a control board.
Sensor and Safety System Repair
Photo eyes and edge sensors prevent the gate from closing on cars or people. When they misalign or short out, the gate reverses or refuses to close. We test sensor alignment, verify edge strip continuity, and replace failed components with matched parts.
Receiver and Remote Troubleshooting
A gate that stops responding to remotes usually points to a dead receiver, failed antenna, or cold solder joints on the board. We test receiver output with a signal meter before condemning the board, which saves you from replacing a working control board when a $40 receiver module is the real problem.
Electric Gate Motor
An electric gate motor is the muscle that moves your gate, and it’s a sealed unit with a finite service life. When the motor burns out, the gate won’t move even if the control board is fine. We test motor windings for resistance, check the capacitor, and verify the drive chain or belt before calling the motor dead. Electric gate motor replacement in Ontario runs $350 to $900 including the motor, labor, and setup, depending on the operator model and whether it’s a residential swing or a commercial slide.
Motor Testing Before Replacement
We don’t replace motors on a hunch. We check amp draw, capacitor health, and thermal overload status first. A motor that trips its thermal overload repeatedly often has a mechanical bind in the gate itself, not a failed motor. Fixing the bind costs less than replacing a motor that wasn’t the root cause.
Motor Replacement and Setup
When a motor truly fails, we match it to your operator’s torque rating and duty cycle. A residential swing motor won’t survive on a commercial slide operator, and we won’t install one that’s under-spec. After replacement, we set the open and close limits, adjust force settings, and cycle the gate to confirm it runs without strain.
Gate Access Control
Gate access control is the electronics layer that decides who gets in: keypads, card readers, intercoms, telephone entry systems, and vehicle loop detectors. When access control fails, tenants can’t get in, deliveries back up, or the gate stays open because the loop detector doesn’t know a car is waiting. We repair and integrate access control as part of our electric gate repair in Ontario, including wiring between the access device and the operator. Access control repair typically runs $150 to $700 depending on whether we’re replacing a keypad, a loop detector, a reader, or re-running signal wiring.
Keypad and Reader Repair
Keypads fail from weather exposure and worn membranes. Card readers fail from power surges or failed readers. We test the output at the control board to confirm whether the problem is the device or the wiring, then replace only what’s failed.
Loop Detector and Entry System Integration
Loop detectors buried in the driveway sense vehicle presence and keep the gate from closing on a car. When they fail, the gate closes unpredictably or won’t open on approach. We test loop frequency and continuity, replace failed detectors, and re-tune the loop to your operator’s input so the access system and the gate work as one.
Commercial Gate Operator
A commercial gate operator runs more cycles in a week than a residential unit runs in a month, and it’s built for that duty cycle. When a commercial operator fails, it’s usually a worn drive component, a failed reversing device, or a control board that’s been hit by a power surge. We service commercial gate operators throughout Ontario, including slide operators on industrial yards and swing operators on apartment entry gates. Commercial operator repair in Ontario runs $350 to $1,400 depending on the operator type, part required, and whether we’re replacing a drive wheel, a board, or a full operator head.
Slide Operator Drive Repair
Commercial slide operators fail most often at the drive: stripped gears, worn chains, or failed drive wheels. We inspect the drive assembly, check for rail wear and gate alignment, and replace components with parts rated for commercial duty cycles. A slide gate that’s out of alignment will destroy a new drive wheel in months. We align before we replace.
Commercial Board and Safety Circuit Repair
Commercial operators have more safety inputs than residential units: multiple loops, photo eyes, edge sensors, and sometimes fire department override. We trace each input at the board, confirm what’s triggering the fault, and repair the failed circuit. That beats replacing a $600 board only to find the fault was a $30 edge sensor.
Brands We Service
We service Viking gate operators, and we know the common failure points on their commercial slide units better than most. Power supply board failures and limit switch drift are the two we see most. Our technicians have replaced enough Viking boards to diagnose them on-site without a second trip.
Ghost Controls and DoorKing are both common in Chino electric gate repair and other Ontario residential communities. Ghost Controls systems are built for DIY installation originally, but we see plenty of them with wiring issues and sensor faults from years of weather exposure. DoorKing operators are built heavier and run for a long time, but their control boards show their age eventually. We stock DoorKing and Ghost Controls replacement parts for common failures. Whether you have one of these or any other make, we can help.

- Gate reverses halfway through closing. This usually means a safety sensor is misaligned or a loop detector is failing. The gate thinks something is in the way. Left alone, the problem gets worse and the gate eventually refuses to close at all.
- Operator hums but the gate doesn’t move. You’re hearing the motor try to run against a stripped gear or a failed capacitor. Running it like this burns out the motor completely, turning a $200 repair into a $700 replacement.
- Gate opens on its own or stays open. A failed receiver, stuck relay on the board, or shorted loop detector causes phantom openings. It’s a security problem and an equipment problem at the same time.
- Remote range dropped to almost nothing. The receiver antenna or the receiver board itself is failing. You shouldn’t have to stand next to the gate with your remote pressed against the picket to get it to open.
- Gate jerks or shudders while moving. That’s a mechanical bind: worn rollers, misaligned track, or a failing hinge. The operator is working harder than it should, and it will burn out the motor or strip the drive gear if you keep running it.
Our Process, Step by Step
- 1
On-site inspection. We arrive at your Ontario property, listen to the symptoms, and physically inspect the gate, operator, and access components. Nothing is diagnosed over the phone; everything is verified on-site.
- 2
Systematic electrical testing. We test voltage at the board, check motor resistance, verify sensor continuity, and test safety devices with the proper diagnostic equipment. This isolates the failed component instead of guessing.
- 3
Clear repair quote. Before any work starts, you get a written price for the repair. No work happens without your approval. The price we quote is the price you pay.
- 4
Repair and testing. We replace the failed part, re-set limits and force settings, and cycle the gate repeatedly under load. We test every safety device before we call the job done.
- 5
Final walkthrough. We show you what was replaced, explain why it failed, and give you straight answers on what to watch for. If a future repair is likely, we tell you then, not later.
How Much Does Electric Gate Repair Cost in Ontario?
A typical electric gate repair in Ontario runs $180 to $600 for most residential repairs: sensor replacements, capacitor swaps, limit switch replacement, and receiver fixes all fall in that range. Motor replacement runs $350 to $900. Commercial operator repairs run $350 to $1,400 depending on the drive component or board that failed. Access control repairs run $150 to $700 depending on the device.
What affects the price: the brand and age of your operator, whether parts are stocked locally or must be ordered, and whether the gate itself has a mechanical bind we need to correct before the operator can run reliably. The cheapest quote usually skips the mechanical check and gives you a repair that fails again. We don’t work that way.
