1. Door behaviour that changes over time

Doors that repeatedly reopen, close with impact, hesitate at one landing or need passengers to move before closing deserve a service record. The cause may vary, so avoid assuming that every door complaint is a sensor fault. Note the landing, time, direction of travel and whether the issue appears during busy periods.

Do not hold doors with objects or try to realign a door by hand. If a landing door appears unsecured, a gap is visible or the car moves with an unsafe door condition, prevent use and report it as a safety concern.

2. Cabin not level with the landing

Passengers can trip when a cabin stops above or below the floor. Record whether the difference happens at one floor, several floors or only under a particular load. A small variation that repeats is still useful evidence because it shows a pattern rather than a one-off passenger impression.

Mark the lift unavailable if the level difference creates a clear trip hazard or if movement continues unexpectedly. Do not ask passengers to test it repeatedly. Share the floor, direction, load estimate and any recent power interruption with the service contact.

3. New noise, vibration, smell or heat

A new scraping, impact, grinding sound or strong vibration should be described in plain language and linked to a point in the journey: starting, stopping, passing a floor or door operation. A burning smell, smoke or unusual heat is more urgent. Stop normal use and involve emergency services where there is fire or direct danger.

People should not enter restricted lift areas to investigate. The safer observation is from the lobby or cabin, followed by an accurate report to the person responsible for technical access.

  • Which lift, tower and floor were involved?
  • Did the symptom happen at start, travel, levelling or door operation?
  • Was there a recent outage, voltage event, water leak or building work?
  • Did the fault clear temporarily and then return?

4. Repeat stoppages, error displays and resets

A reset that makes a lift run again does not explain why it stopped. Record the displayed code or message without opening a controller. If the same issue returns, give the service team the sequence of events and previous visit notes instead of treating each call as unrelated.

Repeated passenger entrapment, uncontrolled movement, abrupt stopping or safety-device activation calls for an appropriate technical review before continued operation. Building teams should resist pressure to keep a frequently failing lift in service simply because it restarts.

5. Turn observations into a useful fault log

Use one log per lift. Record date and time, floor, direction, load context, visible display, sound or movement, passenger status, person informed and action taken. Video can help document a repeat symptom only when it is safe to record and does not delay reporting or expose passengers' personal information.

Review the log for recurrence by floor, time or component. A clear history supports better breakdown diagnosis, an AMC review and an evidence-based decision about repair versus modernization.

Safety and local-requirement note

This article is general information, not a repair manual, remote diagnosis or legal opinion. Do not force lift doors, bypass controls or enter restricted lift areas. Requirements can vary by jurisdiction and building type; confirm current obligations with the responsible local authority and use appropriate lift professionals for site-specific work.
