Troubleshooting common stair lift problems and what to check. If your stair lift is not working, making a strange noise or won’t stop beeping there a few things you can check. These items may save you a repair call and even get your lift up and running again. The list of the most common things to check before you call:
- Power supply
- Key Switch
- Battery Disconnect Switch
- Error Codes
- Quick video overview
Power Supply
Confirm the power supply is plugged into a working outlet. Most power supplies will look similar to the one in this picture. If the power supply is plugged in it may be the outlet is off. 
Check to see if the outlet is a switched outlet or if the breaker has tripped. If it is a switched outlet you will want to have the power supply plugged into a dedicated outlet that is always on. A stair lift is operated and controlled by circuits that should be protected by a surge protector. After confirming the outlet is supplying power and the power supply is plugged in
check the key switch.
Key Switch
While it may seem obvious we often receive calls to find the key switch has been accidentally turned off. Depending on the model lift you have the key switch can be located in a few different places. 
One of the most common locations for the key switch is on the top landing chassis side as shown in this picture. Other places key switches are located are on the chair armrest and lower front cover. Once you locate the key switch verify operation by turning it off and then back on. There are many times a key switch can appear to be in the on position when it is actually turned just slightly to the off position.
Battery Disconnect Switch
The battery disconnect switch is the main shut off switch for the lift. The battery disconnect switch has a different function then the key switch. 
Locating this switch can sometimes be difficult. The switch location will vary depending on the lift manufacture. Typically they are located on the lift in a place that won’t be knocked into easily. This picture is the disconnect switch for the stairlift model Acorn 130. This switch is located on the front panel adjacent to the diagnostics display of the HandiCare Model 1000 stair lift.
Error codes
Most stair lifts have an error code or diagnostics display located on the lift. It is good to read your owners manual and be at least somewhat familiar with these codes. 
After you locate the diagnostics display check to see what error code or codes are showing to diagnose common stairlift problems. Look up the code in your user manual for more details about the error. Some codes will indicate a simple problem and some will refer you to call a local stair lift repair company. It is important to never take the cover off to attempt a repair.
