Why won’t my Stannah stairlift move down, even though the power light is on?

A Stannah stairlift can have its power light on and still refuse to move down because the drive circuit is being interrupted by a safety sensor, control setting, obstruction, seat position or fault. The light confirms that power is reaching part of the stairlift; it does not prove that every safety switch and operating control is allowing travel. Carry out the safe checks below, but do not bypass a sensor or continue using the lift if it behaves unexpectedly.

Check the basic operating position first. Make sure the seat is fully swivelled back into the travelling position and that the armrests are lowered. On models with a powered swivel seat, the stairlift may not travel until the seat is correctly locked. Check that the footrest is not obstructed and that nothing is pressing against the seat, arms or controls.

Look along the stairs and around the carriage for anything that could be touching the lift. Common examples include clothing, shopping bags, pet items, toys or objects that have fallen onto the steps. Check the edges of the footrest and carriage carefully, as an obstruction may operate a safety edge even when the track appears clear. Remove an obstruction only if it can be done safely without reaching into moving parts.

Confirm that the control is set for downward travel. If you are using the armrest control, operate it deliberately in the direction shown by the control markings and keep it engaged as required by your model. A stairlift will normally stop as soon as the control is released. If the control feels loose, sticks, works intermittently or moves the lift in only one direction, stop using it and arrange an inspection.

If you are using a remote control, check that it is switched on and that its batteries have not gone flat. Make sure you are using the remote paired with the stairlift and point it towards the lift if the system requires this. Try the other approved control only if it is safe to do so. If the armrest control operates the lift but the remote does not, the problem is more likely to be the remote, its batteries or its receiver. If neither control allows downward travel, the issue may be a safety circuit, wiring connection, control board or drive component.

Check the key switch and stop control. Some stairlift models have a key switch that prevents operation when it is in the off position. Confirm that the key is inserted and turned to the operating position. Also check that the emergency stop button has not been pressed. Reset it only using the normal procedure described in your user instructions. Do not repeatedly press the stop control or attempt to dismantle it.

Look for a safety sensor or limit switch preventing movement. Stannah stairlifts use safety edges and switches around areas such as the footrest, carriage and seat mechanism. If a sensor detects pressure, an obstruction or an incorrect position, it can stop the motor in one direction or prevent travel altogether. Gently check that the relevant parts are free from contact and in their normal position. Do not tape down, hold open or otherwise defeat a safety switch. These devices are intended to prevent injury and should be tested by a qualified engineer if they remain activated.

Check the charging and power supply indicators. A power light may remain illuminated when the batteries are not sufficiently charged to drive the motor, or when the lift has not been left correctly on its charging point. If your model has a separate charging indicator, check whether it shows normal charging. If the stairlift has been unused for a long period, the batteries may have discharged or deteriorated. Avoid repeatedly attempting to run the lift, as this can reduce the remaining charge. If the lift is at a charging point, leave it positioned as instructed in the manual and seek advice if the charging indication is absent or unusual.

A stairlift may also stop because of a temporary control-system issue. If your instructions provide a specific reset procedure, follow that procedure exactly. Do not switch off electrical supplies, remove covers or reset internal components unless this is explicitly identified as a user operation. Some faults clear after a correct reset, but a recurring fault needs professional diagnosis rather than repeated resetting.

What if it travels up but not down? One-direction operation can point towards a faulty direction control, remote, wiring connection, limit switch, safety sensor or control-board output. It can also result from a control being held or interpreted incorrectly. This is not a condition to work around by applying force or repeatedly operating the controls. Note whether the lift makes a sound, displays a fault indication, stops immediately or travels briefly before stopping. These details can help an engineer identify the likely cause.

What if it stops halfway? A mid-stair stop may be caused by an obstruction, a safety edge being activated, a loss of battery capacity, a track or carriage issue, or an electrical fault. Keep the stairlift stationary and follow the user instructions for safe assistance. Do not attempt to push the chair along the rail, operate it while standing on the stairs or move it if there is a risk of falling. If someone is left in an unsafe position, obtain appropriate assistance and contact the service provider promptly.

Arrange a professional inspection if the simple checks do not restore downward travel, if the lift stops repeatedly, if there is a burning smell or unusual noise, if a warning light or code appears, or if any control, cable or cover looks damaged. A trained stairlift engineer can test the safety circuit, switches, wiring, battery condition, motor and control equipment without compromising the lift’s protective systems. Keep the stairlift out of use until it has been assessed if it moves unpredictably or fails to stop normally.

When reporting the fault, provide the stairlift model if known, whether it travels in the opposite direction, the position where it stops, the status of the power and charging lights, any displayed fault code, and whether the armrest or remote control was being used. This information can make the assessment more efficient. If you are unsure about any check, stop at the first safe point and contact Independent Stairlifts for guidance and an appropriate inspection.
