One controller board fails. Your elevator company calls with news: the part does not exist. Not backordered. Not expensive. Not available at any price.
You now have two options. Pay for full modernization. Or explain to your tenants why the elevator will be down indefinitely.
This is not a scare tactic. This is the reality facing buildings with obsolete elevator equipment. And most property managers do not know they are in this position until the day the board fails.
What Makes Equipment Truly Obsolete
The word "obsolete" gets misused in the elevator industry. A 20-year-old controller is not necessarily obsolete. A 30-year-old controller is not necessarily obsolete. Age matters, but it is not the determining factor.
A controller is obsolete when all three of these conditions apply:
Parts no longer manufactured. The original equipment manufacturer has stopped production. When a component fails, there is no new replacement to order.
Aftermarket inventory depleted. Third-party suppliers once filled the gap by stockpiling parts, reverse-engineering boards, or manufacturing compatible alternatives. When even these sources dry up, you are out of options.
No service path exists. Some obsolete equipment can be nursed along with creative repairs. Others cannot. When board failure means complete system replacement, you have no service path.
Equipment with all three conditions is a countdown. You just do not know when the clock expires.
Controllers With Zero Long-Term Path
Our research has identified several controller platforms with documented obsolescence issues. If your building runs any of these systems, you should be planning for replacement.
Dover DMC (1985-2001)
The largest obsolescence crisis in the industry. TK Elevator (which acquired Dover) officially declared they cannot source critical parts. An estimated 80,000+ DMC controllers remain in service, primarily in hydraulic applications. Every one of them is operating on borrowed time. For the full analysis, see our Dover DMC obsolescence guide.
Virginia Controls MH2000
The primary electronics supplier for MH2000 discontinued support. Upgrade kits (MH2K/3K) are available but represent finite inventory. When the supply depletes, buildings face full controller replacement.
Older Schindler Miconic Systems
The Miconic 10 destination dispatch system was discontinued in 2012, replaced by PORT. Proprietary components and licensing requirements make long-term service increasingly difficult. Our Schindler controller guide covers this in detail.
Equipment Installed Before 2000
Any controller from a manufacturer that no longer exists or has been acquired multiple times warrants scrutiny. Corporate acquisitions often result in discontinued support for legacy platforms.
The Budget Planning Window
If your equipment appears on this list, you have a decision to make. You can wait for the failure and face emergency modernization. Or you can budget now and control the timing.
The numbers:
Controller-only modernization: $50,000 to $70,000. Replaces the brain of the elevator while keeping the existing motor, door equipment, and cab. Fastest option but may not address other aging components.
Full modernization: $100,000 to $400,000 depending on elevator type and building conditions. Replaces controller, drive, motor, door operators, and often cab interior. Higher cost but resets the 25-year equipment lifecycle.
The capital planning rule: if your controller is on the obsolescence list and your equipment is 15+ years old, you should be budgeting for replacement within 3-5 years. Waiting longer risks forced emergency modernization at worse pricing and timing.

When the State Forces Your Hand
Sometimes obsolescence is not your choice. Regulatory authorities can mandate replacement through safety orders.
Recent examples:
SmartRise SRA safety orders. The Technical Standards and Safety Authority (TSSA) in Ontario issued director's orders requiring assessment by June 2025 and software fixes by December 2025. US adoption is expected for applicable installations.
MCE iControl/Motion 4000 orders. Technical Safety BC mandated VFD replacement by August 2024 for affected units.
State inspectors can also fail equipment that cannot be brought into compliance. When your controller runs outdated firmware that cannot be updated because the manufacturer no longer supports it, you may face citation until replacement.
The worst scenario: regulatory deadline + obsolete equipment + no budget. You have no negotiation room. The work happens when the state says it happens, at whatever price the market demands.
How to Check Your Equipment Status
Finding out whether your equipment is at risk takes 15 minutes:
Locate the controller nameplate. It lists manufacturer, model, and installation date. This is in the machine room or controller cabinet.
Ask your vendor directly: "Is this controller still supported? Can you get parts if a board fails?" Listen carefully to the answer. If they hedge, pivot to modernization talk, or cannot give a straight yes, you have your answer.
Check your contract. Many maintenance contracts exclude obsolete equipment from coverage. The contract may cover labor and "available parts." If parts are not available, you are exposed. Upload your contract to our Contract Scanner to identify exclusion clauses.
Start Planning Now
The point of this warning is not to panic you. It is to give you the planning window that emergency failures eliminate.
If your equipment is on this list:
- Get a written obsolescence disclosure from your service provider
- Request a modernization estimate for budget purposes
- Review your contract for parts exclusion language
- Add equipment replacement to your 5-year capital plan
The building that plans for obsolescence on their timeline replaces equipment when it makes sense. The building that ignores the warning replaces equipment when the board fails, during peak season, at emergency pricing.
