Acorn Stairlift Diagnostic Display Codes
What are stairlift codes used for?
The Acorn and Brooks straight stairlift displays a series of Stairlift fault codes. These fault codes are for diagnostic purposes. They help the user or stairlift engineer quickly identify the current status or potential problem.
This is especially useful when trying to explain over the phone to a Stairlift engineer exactly what has happened or gone wrong with the lift. Using these informative codes enables the Stairlift engineer to quickly diagnose the exact cause of the fault or issue. In many cases they can be used them to resolve the problem over the phone. This saves the user money by not having to pay for a callout.
How to use the stairlift display codes:
The very first versions used a series of traffic light coloured led’s to display the fault codes. These were quite hit and miss, especially when the led’s became loose or desoldered from the circuit board in the arm. Also, when carrying out a Stairlift service, these are invaluable for determining whether individual safety circuits are working correctly or not. It eventually moved on to a digital display which showed various letters and numbers in single format as in the following table:
