You’re probably not thinking about your elevator until something goes wrong. But here’s the thing: most elevator failures don’t happen suddenly. They give you plenty of warning signals first.
The problem? Most building managers don’t know what to look for until it’s too late. A minor issue that could’ve been fixed for a few hundred dollars turns into a five-figure emergency repair when the elevator suddenly stops working.
According to the elevator safety research standards, approximately 17,000 elevator-related injuries occur annually, many of which could have been prevented with proper maintenance and early problem detection.
This guide breaks down the eight critical warning signs that mean your elevator needs professional attention right now. Some require immediate action. Others give you a window to schedule service before things get serious. Knowing the difference can save you money and keep everyone safe.

1. Unusual Noises During Operation
Your elevator makes some noise during normal operation. That’s expected. What’s not normal are new sounds you haven’t heard before.
Grinding, squealing, or scraping noises indicate mechanical problems developing in the system. These sounds usually mean parts are wearing down or misaligned components are rubbing against each other.
Banging or clanking sounds are more serious. They often point to loose components that could fail completely without warning. A loose pulley or cable can create intermittent banging that gets progressively worse.
Here’s what different sounds typically mean:
- Grinding noise: Worn bearings or gears needing replacement
- Squealing sound: Belt slippage or brake issues
- Humming/buzzing: Electrical problems or motor strain
- Rattling: Loose panels, doors, or mounting hardware
Don’t wait for these sounds to get louder. They won’t fix themselves, and the underlying problems will only get worse over time.
2. Delayed Door Response Times
Elevator doors should open and close smoothly within consistent timeframes. When you notice doors hesitating, jerking, or taking longer than usual, something’s wrong with the door mechanism.
Door operators contain motors, sensors, and safety edges that work together precisely. When any component starts failing, the timing gets thrown off.
Delayed door closing presents a particular safety concern. If the doors don’t close properly, the elevator shouldn’t move. But worn safety systems might allow movement anyway, creating dangerous situations.
Watch for these door-related warning signs:
- Doors that hesitate before opening or closing
- Uneven movement where one door moves faster than the other
- Doors that require multiple attempts to close completely
- Safety sensors that trigger unnecessarily
Door problems often start small but escalate quickly. What begins as a slight delay can progress to complete door failure within weeks.
3. Uneven Floor Leveling
Your elevator should stop flush with each floor every single time. A height difference of more than half an inch creates a tripping hazard.
Uneven leveling happens when the elevator’s position detection system malfunctions. This could involve worn cables, failing hydraulic systems, or sensor problems that prevent accurate positioning.
The real danger isn’t just the inconvenience. People entering or exiting the elevator don’t expect a height difference. Trip and fall accidents from uneven elevator floors result in serious injuries, especially for elderly passengers or those with mobility limitations.
If your elevator consistently misses the floor level, even by an inch or two, schedule an inspection immediately. This problem indicates wear in critical components that control the elevator’s stopping position.
4. Jerky or Rough Ride Quality
Smooth acceleration and deceleration define a properly functioning elevator. Any change in ride quality signals developing mechanical issues.
Sudden jerks during startup or stopping indicate problems with the motor control system or worn brake components. The elevator should accelerate gradually, maintain steady speed, then decelerate smoothly before stopping.
Bouncing at stops suggests issues with the buffer system or hydraulic problems in hydraulic elevators. The buffers at the bottom of the shaft absorb energy during descent, and worn buffers can’t cushion properly.
Pay attention to these ride quality changes:
- Shaking or vibration during travel
- Sudden stops that feel too abrupt
- Multiple small corrections when leveling at floors
- Swaying motion during travel
These symptoms rarely improve on their own. They progressively worsen as the underlying components continue deteriorating.
5. Frequent Service Interruptions
An elevator that goes out of service repeatedly is crying for help. Even if it comes back online after each incident, the pattern tells you something serious needs attention.
Modern elevators include numerous safety systems designed to shut down operation when they detect potential problems. Frequent shutdowns mean these safety systems keep finding issues worth stopping for.
The elevator modernization guidelines recommend comprehensive system evaluation when service interruptions exceed twice monthly. This frequency indicates systemic problems rather than isolated incidents.
Track these interruption patterns:
- How often does the elevator go out of service?
- Do problems occur at specific times or under certain conditions?
- Does the same error code appear repeatedly?
- How long does it take to restore service each time?
Don’t accept frequent breakdowns as normal. They’re not. They indicate your elevator needs comprehensive professional evaluation and probably significant repairs or upgrades.
6. Strange Odors Coming from the Elevator
Your nose knows when something’s wrong. Unusual smells coming from an elevator indicate potentially serious problems.
Burning smells suggest electrical issues or overheating motors. These odors mean components are getting hotter than designed, which can lead to electrical fires or complete system failure.
Oil or hydraulic fluid smells indicate leaks in hydraulic systems. Even small leaks create safety hazards and environmental concerns. Hydraulic fluid on the elevator floor becomes extremely slippery.
Musty or moldy odors point to water infiltration somewhere in the shaft. Water and elevators don’t mix. Moisture causes rust, corrodes electrical components, and creates slipping hazards.
Never ignore these specific smells:
- Burning plastic or rubber: Electrical shorts or overheating wires
- Hot metal smell: Friction from misaligned or failing mechanical parts
- Oil or grease smell: Hydraulic leaks or over-lubrication
- Sulfur or rotten egg smell: Battery problems in backup power systems
If you smell something unusual, take the elevator out of service immediately and call for professional inspection. Some of these situations present fire risks that need immediate attention.
7. Inconsistent Travel Speed
Your elevator should maintain consistent speed during each trip. Speed variations indicate control system problems or mechanical issues affecting performance.
Slowing down during travel suggests the motor is struggling. This could mean the motor itself is wearing out, or something is creating unusual resistance in the system.
Speeding up unexpectedly is more concerning. This might indicate brake problems or control system failures that can’t properly regulate speed. Modern safety systems should prevent dangerous speeds, but you shouldn’t rely on safety systems to compensate for failing primary controls.
For additional insights on maintaining building systems, check out related resources on building maintenance that cover various mechanical systems.
Watch for these speed-related issues:
- Different speeds between upward and downward travel
- Varying speeds on different days or times
- Gradual speed changes as the elevator reaches capacity
- Sudden acceleration or deceleration mid-travel
Speed control problems indicate issues with critical systems. Don’t wait for these to resolve themselves. They won’t.
8. Error Codes or Warning Lights
Modern elevators include diagnostic systems that display error codes or warning lights when they detect problems. These aren’t suggestions. They’re warnings that something specific needs attention.
Some building managers get used to seeing the same warning light repeatedly and start ignoring it. This is dangerous thinking. That warning light indicates a real problem that your elevator is compensating for through backup systems or reduced functionality.
Error codes provide specific information about what’s failing. Professional technicians can use these codes to diagnose problems quickly and order the right parts before arriving onsite.
Take these actions when you see warnings:
- Document the exact error code or warning light description
- Note when the warning appears (specific times, conditions, or loads)
- Take photos of digital displays showing error information
- Record any unusual behavior accompanying the warning
Share this documentation with your service provider. It helps them diagnose problems faster and ensures they bring appropriate tools and parts for repairs.
Frequently Asked Questions
How often should elevators receive professional maintenance?
Most elevators need professional maintenance every month, though high-traffic elevators may require service twice monthly. Hydraulic elevators typically need more frequent attention than traction systems due to their mechanical complexity and fluid systems that require regular monitoring.
Can I continue using an elevator showing warning signs?
It depends on the specific warning sign. Unusual noises or rough rides might allow continued operation while scheduling service, but burning smells, erratic speed, or frequent shutdowns require immediate removal from service. When in doubt, prioritize passenger safety over convenience.
What causes most elevator failures?
Deferred maintenance causes the majority of elevator failures. Small problems left unaddressed gradually worsen until they cause system breakdowns. Regular professional inspections catch developing issues before they become failures, saving money and preventing dangerous situations.
Are older elevators more likely to show these warning signs?
Yes, elevators over 20 years old show warning signs more frequently as components reach the end of their design life. However, even new elevators can develop problems from poor installation, manufacturing defects, or unusual operating conditions. Age increases likelihood but doesn’t guarantee problems.
How quickly do warning signs typically progress to complete failure?
Timeline varies dramatically based on the specific problem. Some issues like failing brakes can progress from first symptoms to complete failure within days, while others like worn guide rails might take months. This unpredictability makes early professional evaluation critical.
