A stairlift that suddenly stops working is alarming, especially if the person who relies on it is now stuck upstairs or down. The good news is that most stairlift problems are not faults at all but simple issues you can put right in a minute or two. This guide walks through the common causes, the safe checks you can make yourself, and the point at which you should stop and call an engineer.
First, the safe checks
Before assuming the worst, run through the basics. The large majority of callouts turn out to be one of these.
Is the power on? Stairlifts run from a normal mains socket, usually tucked away near the top or bottom of the stairs. Check the switch has not been knocked off, the plug is in, and the socket itself is working. It is surprisingly common for a stairlift to be switched off by accident while cleaning or vacuuming.
Is the lift parked on its charging point? A stairlift charges through contact points on the rail, usually at the top and bottom. If it has been left halfway up the stairs, it is not charging and the battery will eventually run flat. Move it to a charging point and leave it there.
Is the seat in the right position? Most lifts will not move unless the seat, the footrest and the arms are correctly positioned, and the seat is swivelled fully back to face forward. This is a safety feature, not a fault. Make sure everything is locked into its travelling position.
Why is my stairlift beeping?
Beeping is the lift trying to tell you something, and the cause is usually one of two things. Most often it means the battery is low because the lift has been left off its charging point or the power has been switched off. Park it on the charger, leave it on, and the beeping normally stops once the battery recovers.
If the lift is charging and still beeping, the message may relate to the footrest, the hinge rail or the swivel seat not being seated correctly. Gently adjust each one until it clicks into position. Many lifts also use a pattern of beeps as a fault code, so it is worth checking the number of beeps against your user manual, which lists what each pattern means.
The lift will not move at all
If the seat is positioned correctly and the lift still refuses to travel, the usual suspects are a flat battery, a blocked safety edge, or an obstruction on the rail. Stairlifts have pressure-sensitive safety edges around the footplate and carriage that stop the lift the moment they touch something. A stray slipper, a trailing dressing gown cord, a pet toy or even a build-up of dust on a sensor can be enough to trigger them. Clear the staircase, wipe the rail, and check nothing is pressing against the footplate.
A key switch is another easy thing to miss. Many lifts have a removable key that turns the unit on and off. If it has been turned to off or removed, the lift will do nothing until it is turned back on.
Trying a reset
If everything looks right but the lift is unresponsive, a simple reset often clears a temporary glitch. Switch the lift off at the mains, wait around 30 seconds, then switch it back on. This is the stairlift equivalent of turning it off and on again, and it resolves a surprising number of electronic hiccups. If the lift works after a reset but the same problem returns, make a note of when it happens, as that will help the engineer diagnose it.
When to call an engineer
Some things are not safe to tackle yourself, and forcing a stairlift that is faulty can make matters worse. Call a professional if the lift is making grinding or unusual mechanical noises, if it moves jerkily or stops partway, if a fault code keeps returning after a reset, or if you suspect anything electrical. Never attempt repairs on the motor, the wiring or the drive mechanism. If someone is stranded on the lift, most manufacturers and installers run an emergency callout line, and many offer 24-hour cover.
Most of these faults are far less likely to happen in the first place if the lift is serviced once a year. Our stairlift maintenance and repair guide and our advice on how to care for your stairlift cover the upkeep that keeps it running reliably. If you need someone local, our directory of stairlift companies can help you find an engineer.
At a glance
- Beeping: nearly always a low battery. Park the lift on its charging point and leave the power on.
- Will not move: check the seat, footrest and arms are in their travelling position and the key switch is on.
- Stops suddenly: look for an obstruction on the rail or against the safety edges, then clear it.
- Still stuck: switch off at the mains, wait 30 seconds, switch back on.
- Call an engineer for: grinding noises, jerky movement, recurring fault codes, or anything electrical.
Frequently asked questions
Why does my stairlift keep beeping?
The most common reason is a low battery caused by the lift being left off its charging point or the power being switched off. Park it on the charger and leave the power on. If it still beeps, check the footrest, seat and hinge rail are correctly positioned, and look up the beep pattern in your manual.
My stairlift will not move. What should I check first?
Make sure the power is on, the lift is on its charging point, the key switch is turned on, and the seat, arms and footrest are in their travelling position. Then check nothing is obstructing the rail or pressing on the safety edges.
How do I reset my stairlift?
Switch it off at the mains, wait about 30 seconds, then switch it back on. This clears many temporary electronic faults. If the same problem returns, it needs an engineer.
Can I repair a stairlift myself?
You can safely do the basic checks in this guide, such as clearing obstructions, repositioning the seat and resetting the power. You should never attempt repairs to the motor, wiring or drive mechanism. Those need a qualified engineer.
How do I stop the faults happening in the first place?
An annual service is the single best preventative step. It keeps the battery, safety edges and drive system in good order and catches small problems before they leave someone stranded.
