Kustom Diagnoses, Repairs, and Installs Every Opener Brand
Your garage door opener is two things at once. It is a motor — the physical muscle that moves the door up and down. And it is a brain — the electronic control system that manages the motor, processes signals from remotes and wall buttons, monitors safety sensors, enforces travel limits, and increasingly connects to your phone, your smart home, and the internet. When the opener fails, the failure can live in either side of this dual nature — or in the intersection between the two.
A stripped gear is a mechanical problem. A dead circuit board is an electronic problem. A motor that hums but does not turn may be either. A door that opens but will not close is probably a sensor problem, but it could be a limit switch, a wiring issue, or a logic board malfunction. An opener that works intermittently could be a failing capacitor, a loose connection, radio interference, or a circuit board that is degrading from years of heat exposure in a Greenfield garage.
This diagnostic complexity is why opener problems frustrate homeowners and why generic repair approaches — swap the most expensive part and hope for the best — waste money and leave problems unsolved. The opener has at least a dozen subsystems, and accurate repair requires identifying which specific subsystem has failed before any part is replaced.
Kustom diagnoses opener problems at the subsystem level. We isolate the exact failure — mechanical, electrical, or electronic — and repair it with the specific part and technique it requires. When the opener is too old, too damaged, or too obsolete to justify repair, we recommend replacement with honest reasoning and install a new unit with professional calibration and complete smart feature setup.
Whether your opener needs a $50 gear or a complete new installation, call (888) 670-9331. Kustom gets your opener running right.
You can hear the motor running — the familiar hum or chain noise from the ceiling unit — but the door does not respond. The mechanical connection between the motor and the door has been lost. The most common cause is a stripped drive gear — the motor spins but the gear that transfers rotation to the chain, belt, or screw is no longer engaging. The trolley carriage may also have disconnected from the door arm, or the drive chain or belt may have broken.
A completely dead opener — no motor sound, no indicator lights, no response to any control — has lost power or suffered a total electrical failure. Check the outlet first — unplug the opener and plug in another device to confirm the outlet has power. If the outlet is live, the failure is inside the unit — a blown fuse on the circuit board, a failed transformer, a dead circuit board, or wiring that has been damaged by a power surge.
When one control works and the other does not, the problem is in the non-functional control or its connection, not in the opener itself. A dead remote usually needs new batteries or reprogramming. A dead wall button may have a broken wire, a faulty switch, or a damaged connection at the opener terminal. When the wall button works but the remote does not, the remote may need replacement or the opener's receiver may have failed.
A door that begins moving and then immediately reverses has encountered resistance that the opener's safety system interpreted as an obstruction. This can be caused by a binding point in the tracks, a misaligned sensor, force settings calibrated too sensitively, or an actual obstruction. If the sensors check out, the issue is usually mechanical — something in the door system is creating resistance the opener will not push through.

When limits are set incorrectly — often after a spring replacement, a power outage, or an opener reset — the opener stops the door at the wrong position. Limit adjustment corrects this in minutes.
Grinding indicates gear teeth that are worn, stripped, or misaligned. Clicking suggests a drive mechanism that is catching rather than engaging smoothly. Humming without movement indicates a motor receiving power but unable to turn — possibly a seized gear, a locked drive mechanism, or a motor that has bound internally. These sounds are diagnostic signals pointing to specific mechanical failures.
Most modern openers communicate diagnostic information through their indicator lights — specific blink patterns that correspond to specific error conditions. One blink may indicate a sensor issue. Four blinks may indicate a sensor wire problem. Ten blinks may indicate a logic board error. Kustom technicians are trained to read and interpret diagnostic blink codes for all major opener brands, which accelerates diagnosis and eliminates guesswork.
The most common cause of a door that opens normally but refuses to close is a photo-eye sensor problem. The sensors — mounted on each side of the door opening near the floor — must maintain an unbroken infrared beam to allow the door to close. When the beam is blocked, interrupted, or misaligned, the opener reads it as an obstruction and refuses to close the door. Dirty lenses, bumped sensors, cut wires, and sun interference are all common causes.
An opener that functions correctly some of the time and fails unpredictably is one of the more frustrating problems to live with and one of the more challenging to diagnose. Intermittent operation can stem from a capacitor that is failing gradually, a circuit board with a cold solder joint that opens and closes with temperature changes, a loose wire connection that makes contact intermittently, or radio frequency interference affecting remote reception.
Modern openers with Wi-Fi connectivity and smart home integration add a layer of electronic complexity. Smart features can fail independently of core opener function — the door may work fine from the wall button and remote but not respond to the app. Issues may involve the opener's Wi-Fi module, your home network configuration, the manufacturer's cloud service, or the integration with your smart home platform. Kustom troubleshoots smart feature issues alongside core opener diagnosis.
A Broken Spring Mimicking an Opener Failure: The most common misdiagnosis in the garage door industry: the homeowner hears the opener straining and assumes the opener is failing, when the real problem is a broken spring. Without the spring's counterbalance, the door's full weight rests on the opener — far exceeding its capacity. The opener motor may run, strain, overheat, and trigger its overload protection, creating symptoms that look exactly like an opener motor failure. Replacing the opener without fixing the spring results in a new opener that fails the same way for the same reason.
A Snapped Cable Creating Opener Overload: Similar to a spring failure, a broken cable removes balanced support from one side of the door, creating an asymmetric load that the opener was not designed to handle. The opener may manage to move the door partway before the overload creates symptoms that mimic opener failure.
Track or Roller Problems the Opener Can't Push Through: A bent track section, a jammed roller, or a binding point in the door's travel path creates resistance that the opener's safety system detects. The opener reverses or stops — not because it has failed, but because something in the door system is blocking the door's movement.
A Locked Manual Lock That's Blocking the Opener: An embarrassingly common scenario — the manual lock on the side of the door is engaged, physically preventing the door from moving. The opener strains against the lock, creating symptoms that can sound alarming. Disengaging the lock solves the problem instantly.
An opener that appears to have failed may be a perfectly functional opener connected to a door system with a problem elsewhere. Kustom's diagnostic process evaluates the entire system — springs, cables, rollers, tracks, and the door itself — before concluding that the opener is at fault. This prevents the expensive mistake of replacing a good opener while the actual problem persists.

The Drive Mechanism: Transfers rotation to linear motion. Chain drives use metal chains; Belt drives use reinforced rubber; Screw drives use threaded rods.
The Gear Assembly: The most common mechanical failure. Nylon teeth strip over time, especially when the opener overworks due to balance issues.
The Circuit Board — The Brain: Manages motor operation, safety logic, and feature handling. Fails from surges, heat, or age.
The Capacitor — The Starter: Provides the initial burst of energy for the motor. A failure causes humming without starting.
The Limit Switches: Control stop points. Misadjusted limits cause the door to stop short or travel too far.
The Safety Sensors: Infrared beam system. Sensor problems are the leading electronic cause for a door not closing.
The Trolley and Carriage: The mechanical linkage to the door. Tab breakage or rail wear prevent door movement.

The Age Factor: Openers less than 8-10 years old are usually excellent repair candidates. Units older than 12-15 years often have recurring issues that make replacement a better long-term value.
Repair vs. Replacement Cost: If repair cost is less than 40-50% of a new opener, repair delivers better value. At 50% or higher, replacement provides a fresh start with full warranty.
Obsolete Parts: Older legacy brands like Stanley or Allstar may have components no longer manufactured, making repair impossible.
Safety Standards: Replacing pre-1993 openers ensures compliance with federal photo-eye safety laws and current UL 325 standards.
Chain Drive — The Workhorse: The most affordable and durable for heavy-duty use. They are noisier than other types, making them best for detached garages.
Belt Drive — The Quiet Choice: Uses reinforced rubber belts to dramatically reduce noise. The preferred choice for attached garages near bedrooms.
Screw Drive — Low-Maintenance: Uses a threaded steel rod. Fewer moving parts means less maintenance, though performance can be affected by temperature extremes.
Direct Drive (Wall-Mount): Mounts beside the door, freeing up ceiling space. The quietest and least vibrational option, ideal for limited overhead clearance.
Jackshaft Openers: Drives the torsion shaft directly. Designed for cathedral ceilings or low-clearance applications where ceiling mounting isn't possible.
LiftMaster / Chamberlain: Our primary recommended brand. We are fluent in their myQ platform, diagnostic codes, and battery backup models.
Genie: We service all chain, belt, and screw drive models and their Aladdin Connect smart systems.

Multiple cycle tests and auto-reverse verification to ensure the door reacts correctly to obstructions.
Heat Stress: Garage temperatures often exceed 120 degrees in Greenfield. This combined thermal load degrades circuit boards and dries out capacitors. Ventilation is key.
Lightning and Power Surges: Greenfield is a high-lightning region. Near-strikes produce surges that kill logic boards. Surge Protection Recommendation: Kustom recommends dedicated surge protectors on the opener outlet to protect your investment.
Humidity and Corrosion: Moist air promotes corrosion on electrical terminals and connections, leading to intermittent failure and heat-generating resistance.
