Your elevator service company just delivered the news: your drive is "obsolete." The repair that would normally cost $2,000? No longer possible. They're quoting $80,000 for a full modernization instead.
You call an independent mechanic for a second opinion. He examines the equipment, pulls up a parts supplier on his phone, and shows you the component you need. In stock. $1,850 delivered.
What happened? The drive was never obsolete. The manufacturer decided to stop supporting it. These are not the same thing.
This distinction, between engineering obsolescence and business-model obsolescence, costs building owners millions of dollars every year. Here's how to tell the difference, and how to protect yourself when an OEM says "obsolete."
Two Types of Obsolescence
The word "obsolete" gets used loosely in the elevator industry. Understanding what it actually means in any given situation is the difference between a necessary modernization and an unnecessary one.
Engineering Obsolescence (The Real Thing)
Engineering obsolescence occurs when equipment genuinely cannot be maintained. The signs are unambiguous:
Parts no longer exist anywhere. Not from the OEM. Not from aftermarket suppliers. Not from salvage operations. The manufacturing has stopped, the stockpiles are depleted, and board-level repair is not viable. When a component fails, there is no replacement.
No aftermarket alternatives. Sometimes third-party suppliers fill gaps left by OEMs. They reverse-engineer boards, stockpile components, or manufacture compatible replacements. True obsolescence means even the aftermarket has dried up.
The entire industry acknowledges it. When equipment is truly obsolete, every service provider, OEM and independent alike, will confirm it. There's no disagreement because the facts are clear.
The Dover DMC controller is a genuine example. Production ended in 2001. TK Elevator (which acquired Dover) officially declared they cannot source critical parts. An estimated 80,000 DMC controllers remain in service, and when they fail, the options are used boards from salvage, board-level repair if a qualified technician is available, or modernization. There is no option four.
Business-Model Obsolescence (The Manufactured Kind)
Business-model obsolescence is different. The equipment works. The parts exist. But the manufacturer has decided to stop supporting it.
The OEM declares it obsolete. They issue an internal memo. They update their service policies. They train their sales teams to quote modernization instead of repair.
Parts remain available through aftermarket channels. Independent suppliers stock the components. Online marketplaces list them. The equipment can be maintained; the OEM just chooses not to.
Independent service providers can still repair it. Companies without OEM affiliations continue servicing the equipment. They source parts, they make repairs, they keep the elevators running.
This is not obsolescence in any engineering sense. It is a business decision to redirect customer spending toward higher-margin modernization projects.
The KONE V3F16L Case Study
The V3F16L variable frequency drive tells the story clearly.
Timeline:
- Through 2017: KONE was still installing V3F16L drives in new equipment
- 2019: KONE declared the V3F16L obsolete
Two years. From active installation to declared obsolescence in two years.
When KONE says "obsolete," they mean: no technical support from KONE. No parts sales from KONE. No repair service from KONE. When a V3F16L fails in a KONE-serviced building, the solution KONE offers is the KDL16L "upgrade." This is not a repair. It is a partial modernization, typically quoted at $15,000 to $25,000 per elevator.
But here's what the building owner often doesn't know: V3F16L drives are available through aftermarket suppliers. Imperial Electric stocks compatible ACPM power modules. VatorTrader lists V3F16L components. The drives can be repaired by qualified technicians.
The equipment is not obsolete. KONE's willingness to support it is.
This matters because the $80,000 modernization quote (which often follows the initial "upgrade" discussion) may be addressing a problem that doesn't exist. The drive works. Parts are available. An independent elevator company can service it.
Industry practitioner feedback on the KDL16L: "Failures at 5 years. Ride quality issues. We don't recommend it as an upgrade path." The "upgrade" KONE pushes as the solution to V3F16L "obsolescence" has its own problems.
The Economic Incentive
Why would a manufacturer declare functional equipment obsolete? The math explains it.
Repairs are low-margin. A drive repair might generate $2,000 in revenue with thin margins. The technician time, parts sourcing, and warranty exposure make it barely profitable.
Modernizations are high-margin. That same elevator, modernized, generates $60,000 to $150,000 in revenue with significantly better margins. One modernization equals thirty repairs.
The contract cycle reinforces it. Many elevator maintenance contracts contain language like "OEM-certified parts only" or "coverage excludes obsolete equipment." When the OEM declares equipment obsolete, these clauses activate. Suddenly your full maintenance coverage has a hole in it, and the hole is shaped exactly like a modernization sale.
Here's the calculation a building owner faces:
Option A (Staying with OEM after obsolescence declaration):
- $350/month FM contract (with "obsolete" exclusion now active)
- Drive failure: $80,000 modernization quote
- Total: $350/month plus $80,000 one-time
Option B (Switching to independent with aftermarket parts):
- $450/month FM contract (no exclusions)
- Drive failure: $2,500 repair
- Total: $450/month plus $2,500 one-time
The OEM's path costs $77,500 more. The economic incentive to declare obsolescence is obvious.
How to Verify Real Obsolescence
When an OEM tells you equipment is obsolete, verify before accepting. Here's the five-step process:
Step 1: Search VatorTrader
VatorTrader is the elevator industry's marketplace for parts. Search for your specific part numbers. If components appear in listings, the equipment is not functionally obsolete; someone is still buying and selling parts.
Write down the prices. When your service company quotes a modernization, you'll have a comparison point.
Step 2: Call Independent Parts Suppliers
Contact suppliers directly:
- Imperial Electric
- Elevator Parts Center
- ELSCO
Ask specifically: "Do you stock or can you source [part number]?" Document their response. If they say yes, you have proof the equipment can be maintained.
Step 3: Get a Second Opinion from an ISP
Call an independent service provider (not affiliated with the OEM that declared obsolescence). Ask them:
"Can you service this equipment?" "Where would you source parts?" "What's your assessment of remaining service life?"
Independent providers have no incentive to push unnecessary modernizations. If they say the equipment can be maintained, believe them. If you're considering a switch, our guide on how to switch elevator companies covers the process.
Step 4: Check Regional Production Status
Some equipment declared "obsolete" in North America is still being manufactured elsewhere. Schindler Miconic 10 destination dispatch, for example, was discontinued in some markets but continued production in others. Parts may be available through international channels.
Ask your service provider: "Is this equipment still manufactured anywhere globally?"
Step 5: Request Specific Part Numbers
When an OEM claims obsolescence, ask for specifics:
"Which exact components are unavailable?" "What is the lead time if you attempt to source them?" "Can you provide documentation of the unavailability?"
Vague answers like "the whole system is obsolete" or "we don't support it anymore" reveal that this is a business decision, not an engineering reality. A genuine obsolescence situation comes with specific part numbers and documented sourcing attempts.
Contract Protection Checklist
Your elevator service contract either protects you from manufactured obsolescence or exposes you to it. Review these clauses before your next renewal.
Red Flags (Exposing You to Risk)
"OEM-certified parts only": This clause means your service provider can only use parts blessed by the original manufacturer. When the OEM declares obsolescence and stops selling parts, your coverage effectively ends.
"Coverage excludes obsolete equipment": Who defines obsolete? If the OEM does, they control whether your contract covers your equipment. One internal memo declaring obsolescence, and your full maintenance just became an examination contract.
"Best efforts" sourcing language: "Contractor will make best efforts to source parts" sounds protective but means nothing. There's no standard for "best efforts" and no remedy when they fail.
What to Negotiate
Aftermarket parts permission: Explicit language permitting use of equivalent aftermarket components. "Parts manufactured by or certified by" should read "parts meeting manufacturer specifications."
Obsolescence notice requirements: Require written notice at least 12 months before any obsolescence declaration affects coverage. This gives you time to plan rather than react.
Parts availability definition: Define obsolescence by actual market availability, not OEM policy. "Equipment is considered obsolete only when replacement components cannot be sourced from any supplier within 90 days."
Coverage continuation: Require that coverage continue at the contracted level while replacement parts are available from any source, not just OEM channels.

When Modernization Actually Makes Sense
Not every modernization is unnecessary. Sometimes the equipment genuinely needs replacement. The key is understanding the real reasons versus the manufactured ones.
Legitimate Modernization Triggers
Code compliance requirements. Fire service, door protection, seismic requirements. When code changes mandate equipment that your elevator cannot accommodate, modernization becomes necessary. Check our guide on signs your elevator needs modernization for code-driven triggers.
True parts unavailability. When the aftermarket has dried up and even salvage boards are depleted. Dover DMC is approaching this point. Some early Otis Gen2 configurations are there already.
Energy efficiency ROI. Modern VFD drives can reduce energy consumption by 30-60% versus older technologies. If the payback period makes financial sense, efficiency-driven modernization is legitimate.
Callback reduction. If your elevator is generating 15+ callbacks per year despite proper maintenance, the equipment may have reached the point where ongoing repairs cost more than modernization. Calculate your actual callback burden before accepting this rationale, though. Many "high-callback" elevators are actually victims of deferred maintenance, not equipment age.
Not Legitimate Modernization Triggers
"The OEM says it's obsolete." If parts are available through aftermarket channels, the OEM's declaration is a business decision, not an engineering fact.
"We can't get parts." Verify this claim. An OEM might not be able to get parts through their preferred channels. That doesn't mean parts don't exist.
"It's over 15/20/25 years old." Age alone does not determine obsolescence. Well-maintained equipment can run 30-40 years. The Dover Imperial hydraulic systems installed in the 1980s are still running reliably in many buildings.
"You'll have trouble selling the building." This is a sales tactic, not an engineering assessment. Elevator age appears on due diligence checklists, but sophisticated buyers distinguish between maintained equipment and neglected equipment, not between old and new. See our elevator due diligence checklist for what buyers actually evaluate.
Protecting Yourself Going Forward
The OEM obsolescence trap works because building owners don't know the difference between types of obsolescence and don't verify claims. Here's how to avoid it:
Build relationships with independent providers. Even if you use an OEM for service, have conversations with independents. They'll give you honest assessments of equipment condition and parts availability.
Track your own parts. When repairs happen, record the part numbers. When obsolescence is claimed, you can search for those specific components yourself.
Review your contract annually. Hidden clauses that expose you to obsolescence risk may have entered your agreement during renewals. Know what you're signing.
Question modernization pressure. When the $80,000 quote arrives, ask: "What specific components are unavailable? Can you document the sourcing attempts?" The answers reveal whether you're facing engineering reality or business strategy.
The V3F16L drives declared obsolete in 2019 are still running in buildings across the country. They work fine. Parts are available. Independent technicians service them every day.
The only thing obsolete was KONE's willingness to support them.
Knowing the difference could save you $78,000.
