Lift Problem Checker
Select what's happening with your lift and get a quick indication of the areas that may need inspection.
Step 1
Choose a problem
What is happening with your lift?
Select the symptom that best matches the problem.
Possible areas to inspect
This is a preliminary indication only, not a confirmed diagnosis.
Need the problem inspected?
Get a professional inspection instead of repeatedly resetting a recurring lift fault.
Common Lift Problems
Lift problems can originate from mechanical, electrical, control, door, safety or power-related systems. The same symptom can sometimes have more than one possible cause.
Door Problems
Door operators, rollers, tracks, sensors, locks, interlocks and alignment may need inspection.
Jerking or Vibration
Drive performance, encoder feedback, traction, guide components and mechanical alignment may need checking.
Unusual Noise
Bearings, brakes, traction equipment, guide components and door mechanisms may need inspection.
Incorrect Leveling
Leveling sensors, encoder feedback, drive performance, brake operation and floor-positioning systems may be involved.
Frequent Breakdowns
Repeated faults may require checking the door system, electrical connections, controls, ageing components and maintenance history.
What can cause common lift problems?
Common inspection areas can include door operators, landing door locks, safety circuits, controllers, drives, motors, brakes, encoders, sensors, wiring, power supplies, guide components and emergency systems.
Can this tool diagnose a lift?
No. The Lift Problem Checker is designed only to give a preliminary indication of possible areas to inspect. The actual fault should be established through appropriate technical inspection and testing.
When should a lift be inspected?
A professional inspection should be considered when a lift repeatedly stops, jerks, makes unusual sounds, has door problems, stops inaccurately, fails to respond to calls, or behaves abnormally after a power failure.
Lift Problem Checker FAQs
Why is my lift not working?
A lift may stop working because of issues involving
the door interlock, safety circuit, controller,
power supply, drive, brake, motor or other components.
The exact cause requires technical inspection.
Why is my lift making noise?
Unusual noise can come from door mechanisms,
bearings, guide components, traction equipment,
brakes or other mechanical and electrical components.
Why does my lift jerk while moving?
Jerking can be associated with drive performance,
motor or traction components, encoder feedback,
guide components, leveling systems or mechanical alignment.
Why is my lift door not closing?
Possible inspection areas include the door operator,
door sensors, rollers, tracks, locks, interlocks,
alignment and associated wiring.
Why does my lift stop above or below the floor?
Incorrect leveling can involve position feedback,
encoder systems, drive performance, brake operation,
leveling sensors or mechanical conditions.
Can this tool tell me which part to replace?
No. The tool identifies possible inspection areas rather
than recommending replacement parts. Replacement should
follow proper diagnosis and testing.
