Most Common Elevator Repairs in Commercial Buildings
Commercial elevators are built for long-term performance, but even well-maintained systems require attention over time. In high-traffic commercial buildings, certain components experience more wear than others, leading to the most common elevator repairs.
With years of experience servicing commercial elevators, Metro Elevator helps building owners address issues before they become major problems. Understanding which components fail most often helps owners plan budgets, reduce downtime, and make smarter repair or modernization decisions. For tips on spotting problems early, check out our blog: 7 Signs Your Elevator Needs Repair Before It Becomes a Major Problem.
Here are the five most common elevator repairs we see in commercial properties—and how Metro Elevator can help keep your equipment running smoothly.
Door Operator and Door Component Repairs
Elevator doors are the most frequently used moving part of the system. In many buildings, doors cycle thousands of times per week.
Usage varies between properties. Some elevators may run 50 trips per day, while others in busy office towers or hospitals can exceed 1,200 trips daily. Over time, this constant cycling places stress on door operators, rollers, tracks, and safety devices.
Most Common Door Repairs:
Replacing worn rollers
Repairing or replacing door operators
Adjusting misaligned tracks
Replacing damaged safety sensors
Fixing bent door gibs or clearing debris from tracks
Why Doors Fail:
Constant daily use
Dirt and debris buildup in tracks
Doors being struck by carts or equipment
Worn mechanical components
Aging equipment
In many buildings, door-related issues account for a large portion of elevator service calls. When components wear out or fall out of alignment, technicians repair or replace parts to restore safe, reliable operation.
Metro Elevator technicians routinely inspect door systems, adjust mechanisms, and replace worn components to keep elevators operating smoothly and minimize disruption for tenants.
Elevator Controller Repairs and Failures
The controller is the “brain” of your elevator. It manages movement, leveling, speed, and floor selection.
Controller issues vary significantly depending on the age and manufacturer of the system.
Typical Controller Repairs Include:
Replacing circuit boards
Fixing communication errors
Updating outdated software
Repairing electrical connections
Why Controllers Fail:
Power surges or brownouts
Aging electronics
Heat exposure in machine rooms
Obsolete technology
Some older control systems are built to tolerate fluctuations in temperature or power conditions, while certain newer systems can be much more sensitive and may shut down during even minor electrical disturbances.
In many cases, a controller may have run 24 hours a day, 365 days a year for decades. While it may have an excellent track record, aging systems eventually reach a point where continued repairs become less practical.
Metro Elevator can evaluate your system, repair controllers, or guide you through modernization options to improve reliability and efficiency.
Motor and Drive System Repairs
The motor and drive system physically move the elevator cab and handle the heavy lifting required for daily operation.
Different types of drive systems exist depending on the elevator design, including pump motors, motor-generator systems, and modern solid-state drives. Each has its own lifecycle and maintenance expectations.
Common Repairs:
Bearing replacement
Drive recalibration
Motor rewinding or replacement
Brake adjustments
Why They Wear Out:
Heavy daily usage
Lack of lubrication
Deferred maintenance
Equipment age
Like any mechanical system, these components experience gradual wear over time. When addressed early, many issues can be repaired before they develop into larger system failures.
A skilled technician can quickly assess motor and drive systems, perform preventative maintenance, and repair or replace components to avoid major downtime.
Elevator Leveling System Repairs
Precise floor alignment depends on properly functioning sensors, brakes, drive systems, and door restrictor components.
Typical Leveling Repairs:
Sensor replacement
Brake adjustments
Recalibrating the drive system
Adjusting pickup rollers or door restrictors
Why It Happens:
Normal wear over time
Control system drift
Mechanical brake wear
Misalignment of pickup rollers or restrictors
Leveling issues are not just performance concerns—they can also create safety risks and potential liability if passengers encounter uneven floor alignment.
In many cases, technicians diagnose leveling problems by investigating symptoms such as ride irregularities or unusual noises during travel. Once identified, adjustments to sensors, brakes, or restrictor components can restore proper floor alignment and smooth operation.
Electrical and Wiring Repairs in Elevators
Elevators rely on complex electrical systems to function properly.
Common Electrical Repairs:
Tightening loose connections
Replacing damaged wiring
Addressing blown fuses
Repairing lighting circuits
Why Electrical Issues Develop:
Moisture exposure
Corrosion
Power fluctuations
Aging infrastructure
Environmental conditions can also contribute to electrical issues. For example, machine room temperatures that exceed recommended limits or water intrusion can affect sensitive electrical components and lead to system faults.
Electrical problems often start small but can escalate quickly if left unaddressed, leading to costly repairs or unexpected downtime.
Repair vs. Modernization: When Does It Make Sense?
If your elevator is 20-25+ years old and requires frequent controller or drive repairs, modernization may reduce long-term costs.
Signs repair may no longer be cost-effective:
Increasing annual repair expenses
Hard-to-source parts
Repeated failures of the same components
Outdated control systems
Modernization can improve reliability, energy efficiency, parts availability, and long-term safety compliance, often reducing emergency repair costs over time. A professional evaluation can help determine the best solution for your building.
Keep Your Elevators Running Safely and Reliably
While these are the most common commercial elevator repairs, many issues can be minimized through consistent preventative maintenance.
If you notice unusual elevator performance, it’s important to address early warning signs before small problems become major repairs.
Contact Metro Elevator today to schedule a professional repair evaluation or preventative maintenance review and keep your elevators running safely and reliably.
