AfterTrusted Gate Opener Repair Nationwide
When a gate opener stops working, the problem is rarely one single failure. It’s usually a mix of wear on moving parts, a limit switch that slipped out of adjustment, or a circuit board that got fried by a surge. Calder Gate Repair has specialized in Los Angeles Gate Opener Repair since 2009, as part of the Relay Home Co. family, and our technicians arrive trained on nine major brands including LiftMaster, DoorKing, Mighty Mule, and Elite. Most repairs are completed the same day. You get a written price before any work starts, and every job carries the 365-Day Done Right Promise. If the repair fails within a year, we come back free. Call (903) 417-0793 and a live person answers, 24/7.

Gate Operator
A gate operator is the full mechanical and electrical assembly that opens and closes the gate, often a swing arm or a slide track driven by a motor. It’s more than just the motor: it includes the control board, limit settings, safety inputs like photo eyes and edges, and the power supply. You need attention on the whole operator when the gate only moves halfway, stops mid-cycle, or trips its breaker repeatedly. Calder Gate Repair troubleshoots the entire operator as one system. A limit switch repair, a common operator fault, typically runs $175 to $240; a replacement circuit board runs $340 to $520 including the part and install. Most operator diagnostics are completed in one visit.
Limit switch calibration
The limit switch is what tells the gate when to stop. When it’s off, the gate bangs into the post or opens too far and stalls. We check both open and close limits, reset them to spec, and test the gate through several full cycles before leaving.
Control board replacement
If the board isn’t responding to remote commands, the fix is often a full board swap rather than a patch. We carry boards for LiftMaster, DoorKing, Mighty Mule, and Elite among others, and we program the new board to your existing remotes and keypad.
Electric Gate Closers
Electric gate closers are the mechanisms that make sure a gate returns to a closed position, either on its own after a set time or when commanded. A gate that swings back open after closing, or one that slams shut because the hydraulic closer failed, usually points here. We commonly see this in communities where wind load or a sloping driveway puts extra strain on the closer. Calder Gate Repair services electric gate closers by checking for leaks, replacing seals, and adjusting the closing force and speed to match the site. A closer adjustment and seal replacement typically runs $150 to $280. A full closer replacement, including the new unit, falls between $300 and $550 depending on the gate’s size and weight.
Closer force and speed
The closer must be set for the gate’s actual weight and the terrain it sits on. Too fast and it slams; too slow and it never seats. We set the latch speed, sweep speed, and closing force to match the opening.
Seal and fluid repair
Hydraulic closers leak from the seals first, and once the fluid is low the unit runs dry and scores its internal cylinder. A timely seal replacement stops a $200 problem from becoming a $500 replacement.
Gate Servicing
Gate servicing is scheduled maintenance that catches failures while they’re still cheap to fix, before a stuck gate or a dead motor shuts down a driveway or property entrance. Calder Gate Repair recommends an annual service visit for any gate that cycles more than ten times a day, and twice a year for gates on busy properties. We lubricate hinges and rollers, check torque on all mounting hardware, clean and re-seat the limit switches, test safety loops and photo eyes, and tighten all electrical connections. A standard single-gate service visit runs $145 to $260. If we find a worn part mid-service, the repair price is written and agreed before any extra work.
Electrical connection inspection
Loose terminals and corroded connections are behind a surprising number of intermittent failures. During a service we check every terminal block, re-torque, and apply dielectric grease where needed, because heat in a loose connection is what kills control boards early.
Safety device testing
Photo eyes, loop detectors, and edge sensors all need to work together. We test each one, confirm they trigger the gate to stop and reverse, and realign anything that’s out of position.
Gate Intercom
A gate intercom is the call box and inside handset or app link that lets a visitor call into the house before the gate is opened. It often shares wiring and power with the gate opener itself, so when the intercom stops working, the fault is frequently in the shared wiring or power supply, not just the handset. Calder Gate Repair troubleshoots the full intercom link from the call box at the gate post through to the indoor unit. A handset or speaker replacement typically runs $120 to $220. Rewiring a damaged cable, or adding a wireless bridge where a buried line failed, runs $180 to $380 depending on the run length.
Wiring and power diagnosis
We test the voltage at the call station first, then trace the cable path back to the control board. Exposed cable at the post base is a common failure point that’s visible on almost every site we diagnose.
Call box replacement
Water intrusion is what kills outdoor call boxes. We always replace the weather gasket, re-seal the back box with fresh silicone, and verify the new unit pairs with the property’s indoor handset or app before leaving.
Gate Opener With Keypad
A gate opener with keypad lets you or a visitor enter a code to open the gate without a remote. The keypad is a separate component from the opener itself, and the most common failures are keypad weather damage, code memory loss after a power outage, or mismatched wiring between keypad and control board. Calder Gate Repair services keypads on swing and slide gates across all the major brands we carry. A simple re-pair or reprogramming visit is $120 to $180. If the keypad needs replacing, expect $190 to $310 with the new outdoor-rated unit included.
Code reprogramming
After a power outage, some boards forget their stored codes. We can re-pair the keypad to the board, walk you through setting a new PIN, and show you how to add a temporary code for delivery drivers or guests.
Weatherproofing the installation
Keypads that stop working after rain are almost always a seal issue. We reuse the existing wiring where it’s good, install a fresh back gasket, and bed the housing in a weather seal that keeps moisture out of the circuit board.
Brands We Service
DoorKing units remain one of the most common we see on slide gates at residential properties. We know the swing arm and the slide operator lines well, and our vans typically carry DoorKing boards, limit switches, and receiver parts. A lot of DoorKing failures we catch early are simple limit setting drift on units installed more than eight years ago.
Mighty Mule and Elite units are popular on light residential swing gates, and both brands have their own quirks. Mighty Mule control boards are sensitive to power supply ripple, and Elite operators use a specific programming sequence that most generalists fumble. Our techs are trained on both, and they leave with the board programmed, the remotes paired, and the limits set. Whether you prefer DIY vs Professional Gate Opener Repair or need expert help with LiftMaster, DoorKing, Mighty Mule, Elite, or another make altogether, we can help.
Signs You Need a Pro Right Now
- The gate stops halfway and won’t move without a push. This usually means the limit switch has failed or the gearbox is binding. Continuing to operate the gate this way can burn out the motor, which costs far more than a switch replacement.
- The opener hums but nothing moves. A humming motor with no movement points to a locked-up gearbox or a capacitor that’s gone. Powering through it can destroy the motor windings in under a minute.
- The gate reverses on its own and starts grinding. That’s often an obstruction sensor or an edge sensor sending false signals, but a stripped gear can sound the same. Both need diagnosis before the parts fail completely.
- Water is pooling around the arm or the motor. Moisture ingress is the leading cause of control board failure. If the board is still alive, we can dry and seal it. If it’s gone, replacement is the only fix.
- The keypad or intercom stopped responding after rain. That’s a sign your outdoor electronics are letting water in. Left unchecked, that same water travels to the control board and doubles the bill.

How Much Does Gate Opener Repair Cost?
A typical gate opener repair runs $185 to $540 before parts, depending on the failure. Limit switch adjustments and remote receiver repairs sit at the bottom of that range, usually $120 to $240. A control board replacement is the most expensive common repair, running $340 to $520 with the part and programming included. What changes the price most is the brand: DoorKing and FAAC boards cost more than entry-level Mighty Mule boards. Access is also a factor, since a slide gate embedded in a wall or a swing gate on uneven ground takes more time to service safely.
The best way to avoid overpaying is to get a written diagnosis before the work starts. Every Calder Gate Repair estimate shows the labor, the part number, and the total, and that number does not change at the door. A free estimate includes the trip, the diagnostic work, and the written price. There’s never a charge just to come out and look.
