There is no single age at which every elevator must be modernized. In many buildings, an elevator may start to require a modernization assessment after around 15–20 years of service, while some systems can operate reliably for longer with proper maintenance.

Age, however, is only one part of the decision.

The more useful question is:

Is the existing elevator still safe, reliable, maintainable, and economical to operate?

An elevator that is 18 years old but well maintained may not require immediate modernization. On the other hand, a younger elevator with frequent failures, obsolete control equipment, or difficult-to-source parts may already be a strong candidate for an upgrade.

FUJISJ-EM provides elevator modernization components and technical support for contractors, maintenance companies, distributors, and building operators working with aging elevator systems.

Is 15–20 Years the Right Time to Modernize an Elevator?

The 15–20 year range is often a useful point for evaluating modernization, rather than an automatic replacement deadline.

By this stage, some electrical and control components may be approaching the end of their practical service life.

Typical areas that may require closer attention include:

• Elevator controller
• Main control board
• VVVF drive
• Door operator
• Encoder
• Safety devices
• Passenger operating panels
• Communication and monitoring equipment

Some mechanical components may remain in good condition and can potentially continue operating after inspection.

This is why modernization is often more practical than replacing the entire elevator.

Elevator Age vs Actual Condition

Two elevators of the same age can have very different modernization requirements.

Consider two 20-year-old elevators.

Elevator A

• Regularly maintained
• Low fault frequency
• Spare parts remain available
• Good ride quality
• Reliable door operation

This elevator may only require selected upgrades or continued maintenance.

Elevator B

• Frequent breakdowns
• Obsolete controller
• Difficult-to-source boards
• Increasing maintenance costs
• Poor leveling
• Door problems

This elevator is a much stronger candidate for modernization.

Age provides a starting point for evaluation. Actual equipment condition should determine the scope of the upgrade.

5 Signs an Older Elevator May Need Modernization

1. Frequent Breakdowns

If the same elevator repeatedly experiences faults, the problem may no longer be isolated to one component.

Repeated failures involving the controller, drive, door system, or electrical equipment can indicate that several major components are aging at the same time.

2. Maintenance Costs Are Increasing

An aging elevator may require increasingly frequent repairs.

Watch for:

• More service calls
• Higher replacement-part costs
• Longer troubleshooting time
• Increasing labor costs
• Repeated repairs to the same system

When maintenance becomes a recurring expense rather than occasional servicing, modernization should be considered.

3. Critical Parts Are Obsolete

Parts availability can become a major issue as elevator systems age.

Older controllers, drives, and electronic boards may be discontinued.

This can result in:

• Longer sourcing times
• Limited stock
• Higher costs
• Dependence on used parts
• Extended elevator downtime

If critical spare parts are becoming difficult to obtain, upgrading the relevant system can provide a more sustainable solution.

4. Ride Quality Has Declined

Passengers may notice:

• Jerky acceleration
• Hard stopping
• Vibration
• Poor leveling
• Slow operation

These symptoms can be related to the drive, encoder, controller, traction system, or mechanical wear.

A modernization assessment can identify which components are responsible.

5. Door Problems Are Becoming Common

Elevator doors operate thousands of times during normal service.

As the door system ages, problems may include:

• Slow opening
• Slow closing
• Door reopening
• Door operator faults
• Uneven movement
• Increased noise

A door operator or door control upgrade can sometimes resolve these issues without replacing the entire elevator.

What Happens After 20 Years?

After 20 years of service, an elevator does not automatically become unsafe or unusable.

However, 20 years is a sensible point for a more detailed modernization assessment, particularly in commercial and high-traffic buildings.

At this stage, owners should review:

• Breakdown history
• Maintenance expenditure
• Spare-part availability
• Control system condition
• Drive system condition
• Door performance
• Safety equipment
• Ride comfort
• Energy performance

The result of this assessment can determine whether the elevator needs:

continued maintenance → partial modernization → comprehensive modernization → full replacement

What About Elevators Over 25 Years Old?

Elevators that have been operating for more than 25 years deserve particularly careful evaluation.

This does not mean every 25-year-old elevator must be replaced.

However, the probability of encountering obsolete technology and difficult-to-source components generally becomes more significant.

A comprehensive inspection should consider whether the existing system can reasonably support another service cycle.

In some cases, upgrading the controller and drive may provide a practical improvement.

In others, extensive modernization may be necessary.

Where the existing structure or major mechanical systems are no longer suitable, full replacement may make more sense.

Which Components Are Usually Considered for Modernization?

The modernization scope depends on the elevator condition.

Common upgrade areas include:

Controller and Mainboard

An aging controller can limit system reliability, diagnostics, and compatibility with newer equipment.

VVVF Drive

A modern drive can improve motor control, acceleration, deceleration, and ride comfort.

Door Operator

Replacing outdated door equipment can improve door movement and reliability.

Encoder

An encoder provides speed and position feedback and may be upgraded when the existing device is obsolete or unreliable.

Safety Components

Safety light curtains, switches, and related equipment may be evaluated as part of a modernization project.

Traction Machine

The traction machine can be inspected to determine whether it should remain in service, be repaired, or be replaced.

Should You Modernize at 10, 15, 20, or 25 Years?

There is no universal answer, but the following framework can help:

These are planning guidelines, not mandatory replacement ages. Local regulations, equipment condition, maintenance history, and building requirements should always be considered.

Modernization vs Full Replacement

The age of the elevator can also help determine whether modernization or full replacement is more appropriate.

Modernization May Be Suitable When:

• The elevator structure remains in good condition
• Major mechanical components are serviceable
• Problems are concentrated in electrical or control systems
• Spare parts are becoming obsolete
• The building needs shorter downtime
• The owner wants to control investment

Full Replacement May Be Better When:

• Major structural problems exist
• Multiple critical systems are beyond economical repair
• The existing architecture severely limits upgrades
• Major building renovation is already planned
• Long-term replacement provides better overall value

For many aging elevators, modernization provides a middle ground between continued repair and complete replacement.

How FUJISJ-EM Supports Aging Elevator Upgrades

Once an elevator has been identified as a modernization candidate, selecting compatible replacement components becomes a key part of the project.

FUJISJ-EM supplies elevator modernization components for different upgrade requirements, including:

• Elevator controllers
• Mainboards
• VVVF drives
• Door operators
• Door controllers
• Encoders
• Safety light curtains
• Traction machine components
• Elevator operating panels
• Other elevator spare parts

Customers can provide existing equipment information, model numbers, nameplate details, or equipment photos to help identify suitable replacement solutions.

This can be particularly useful when working with older elevators where original components are no longer readily available.

Conclusion

The age of an elevator should be treated as a warning signal, not a replacement deadline.

Around 15–20 years, it is reasonable to start evaluating whether modernization makes sense. Beyond 20 years, maintenance costs, obsolete components, parts availability, ride quality, and system reliability become increasingly important considerations.

For elevators over 25 years old, a more comprehensive assessment can help determine whether targeted modernization, extensive modernization, or full replacement offers the best long-term solution.

The right decision comes from looking at the whole system—not just the number of years it has been operating.

With elevator controllers, drives, door systems, encoders, safety components, and other modernization parts, FUJISJ-EM supports customers in upgrading aging elevator systems with practical, project-focused solutions.
