Acorn Stair Lift Troubleshooting: A Comprehensive Guide

How Does an Acorn Stair Lift Work?

Before we delve into troubleshooting, let’s look at how an Acorn stair lift works. It’s a motorized chair that runs up and down a track installed on your stairs. The chair is connected to a carriage that travels along the track, which is fixed to the side of your staircase. When not in use, the chair folds up tightly against either end of the staircase.

The lift operates on electricity and has its own battery backup in case there is a power outage. When you activate the lift using a control (usually located on the armrest), it starts moving slowly along the track until it reaches its destination at either end of your stairs.

Troubleshooting Common Issues with Your Acorn Stair Lift

Here are some common problems users face with their Acorn stair lifts and possible solutions:

Issue: Stair Lift Doesn’t Operate

If your stair lift isn’t operating at all when you press the controls, check:

  • Whether it’s properly plugged into an electrical outlet.
  • If any circuit breakers have tripped.
  • The battery charge level.


  • Make sure that the chair is correctly placed onto its carriage.
  • Check if there are any loose connections or damaged wiring.
  • If everything seems fine, try resetting your unit by turning off its power source for 30 seconds before reconnecting.

Issue: Chair Moves Erratically

If your chair moves erratically when traveling along the track, check:

  • Whether it’s properly seated onto its mounting bracket.
  • If there is any debris or obstacles on the track.
  • If there is any damage to the track itself.


  • Adjust the chair’s position onto its mounting bracket, ensuring that it is secured both at the bottom and top.
  • Clean off any debris on the track, such as dirt or dust.
  • Check if there are any areas of damage on the track causing friction. Remove these using sandpaper or a file.

Issue: Chair Stops Suddenly

If your chair stops suddenly during use, check:

  • Whether there is anything obstructing the carriage path.
  • If there is a loose connection in any wiring.
  • If there are problems with your batteries, such as low charge levels.


  • Remove any obstructions from your carriage’s path before using your stair lift.
  • Ensure all connections are tightened and free of corrosion or rust buildup.
  • Check battery levels and replace them if needed.

Additional Tips for Keeping Your Acorn Stair Lift Functioning Well

To ensure that your Acorn stair lift stays in good working order, here are some additional tips:

  1. Regularly clean your unit: Dust and debris can accumulate over time and cause issues with your stair lift. Use a soft cloth or vacuum cleaner to clean your lift frequently.

  2. Inspect tracks and wiring: Over time, wear and tear can cause damage to tracks and wires. Regularly inspect them and repair or replace damaged components.

  3. Keep batteries charged: Make sure that you keep your batteries charged regularly so that they don’t lose power unexpectedly.

  4. Contact professionals for maintenance: While many issues can be resolved through troubleshooting, some require professional assistance. Contact Acorn Stairlifts’ customer service for help with more complex issues.


Hopefully, this guide helped you resolve common issues with your Acorn stair lift through troubleshooting techniques. With some basic knowledge of how your unit works and regular maintenance checks, you can keep your stair lift running smoothly for years to come.
