Acorn stairlifts use microprocessor boards with power devices to control the lift motor and like anything electronic parts fail. In these cases it’s often the DG38L-7021-30-1024 relay that needs to be replaced.
The relay failure will produce an Acorn stairlift F1 fault. I can source and replace the faulty relay. Contact me for a repair quote.
The relay can often be identified as faulty by giving it a light tap when it’s in fault mode. A lot of current passes through this relay and the contacts fail.
The DG38L-7021-30-1024 relays aren’t the easiest to remove as the relay has large internal pieces of metal that draw the heat away from the soldering iron. The circuit board also has large areas of copper tracking that do the same thing. If you’re not skilled at desoldering I don’t recommend a DIY repair as you could easily damage the board.
I can do one off repairs or a quantity of them.
Note that some newer boards have replaced the relay with a modern solid state device that I can’t obtain. The old relay is a large square black part with DG38L-7021-30-1024 written on it.
The photos below show the Acorn stairlift circuit boards I can replace the relays on.
Stairlifts also have little sensor circuit boards and the wires that are soldered to them become detached or broken that I can also repair.
If you need the DG38L-7021-30-1024 relay replaced on your Acorn stairlift boards (or any other board that uses it) or the small sensor boards repairing please contact me for a repair quote. Faulty boards can be shipped to me or dropped off.
