What should I do if my lift chair is making unusual noises?

Unusual noises from a lift chair usually indicate an obstruction, a loose fitting, a worn moving component or a fault in the motor, gearbox or electrical system. Stop and assess the chair rather than continuing to use it, particularly if the sound is loud, sudden, repeated or accompanied by jerky movement, an unusual smell, heat, smoke or difficulty operating the handset.

Make the chair safe first. Release the handset, allow the movement to stop and unplug the chair from the mains if it is safe to do so. Keep clear of the footrest, seat mechanism and lifting arms while the chair is moving. If the chair has stopped in a raised or reclined position, do not try to force it back manually. Contact Independent Stairlifts for advice or an inspection.

Check for simple external causes. Once the chair is stationary and disconnected from the power supply, look around the base and footrest for objects, clothing, cables or pet toys that could be rubbing against the mechanism. Check that the power lead and handset cable are not trapped beneath the chair or caught in a moving section. You can also check that the chair is standing securely on a suitable, level surface. Do not reach underneath the chair or place your hands near moving parts.

Do not remove the upholstery, motor covers or electrical covers to investigate the noise. Lift chairs contain moving mechanisms and mains-powered components, and an apparently minor adjustment can affect safe operation. Avoid applying oil, grease or other lubricant unless the manufacturer or a qualified technician has specifically advised it. The wrong lubricant can attract dust, damage components or reach the upholstery and electrical parts.

The type of noise can provide useful information:

• A light squeak or creak may come from normal movement between covers, joints or frame components, but it can also indicate a dry pivot, loose fitting or developing wear.
• Clicking or repeated ticking may be associated with a relay, handset, wiring connection, actuator or control system. Repeated clicking without normal movement should be checked rather than ignored.
• Grinding, scraping or crunching can indicate an obstruction, misalignment, worn gear or damaged moving component. Stop using the chair until it has been inspected.
• A humming, buzzing or straining motor may suggest that the actuator or gearbox is under unusual load, the mechanism is obstructed or the electrical supply is not functioning correctly.
• Knocking or clunking can result from a loose fixing, frame movement or a component reaching an abnormal position. Continued use may increase the damage.
• A crackling sound, burning smell or sound from the plug, cable or control box should be treated as an electrical fault. Switch off and unplug the chair if this can be done without touching damaged wiring, then arrange urgent professional assistance.

A noise that occurs only during lifting, lowering or reclining may point to the relevant actuator or linkage. A noise that continues while the chair is stationary may be more likely to involve the handset, control box, power supply or another electrical connection. This distinction is helpful, but it does not provide a safe diagnosis on its own.

If the noise is quiet and the chair continues to move normally, you may make a brief external check for an obstruction and listen for when the sound occurs. Do not repeatedly cycle the chair to reproduce the noise. If it returns, becomes louder or is present during every movement, stop using the chair and arrange a repair assessment.

Contact Independent Stairlifts promptly if:

• the chair moves unevenly, jerks, stalls or fails to complete a lift or recline cycle;
• the footrest, backrest or seat does not align correctly;
• there is visible damage, looseness or movement in the frame or mechanism;
• the handset, cable, plug or control box shows damage;
• the chair smells of burning, becomes unusually hot, sparks or trips the electrical supply;
• the noise continues after you have removed any accessible obstruction; or
• you are unsure whether the chair is safe to use.

When reporting the problem, describe the sound in everyday terms and state when it happens: during lifting, reclining, returning to the upright position or when the footrest operates. Tell us whether the chair is still moving normally, whether the noise started suddenly and whether there has been any recent movement of the chair, cleaning around it or accidental impact. A short recording made from a safe distance can sometimes help, provided you do not operate the chair solely to create the recording.

A technician can inspect the frame, linkages, actuator, motor, gearbox, wiring, handset and control system, while checking that the chair remains stable and operates within safe limits. The solution may involve removing an obstruction, securing a fitting, replacing a worn part or repairing an electrical or drive component. The chair should not be returned to normal use until the underlying cause has been identified and the operation has been checked.

Do not accept a persistent grinding, electrical or straining noise as normal wear. Early inspection can prevent a minor loose or worn component from placing extra load on the motor or causing the chair to become unusable. If your lift chair is making an unusual noise now, leave it in a safe position, disconnect it where appropriate and contact Independent Stairlifts for further guidance.
