Stairlift circuit boards and controllers.
Stairlifts are controlled with circuit boards that perform many different functions including normal operation, safety fault monitoring, battery charging and more. On occasion, these boards can randomly stop working and prevent a lift from moving. If a circuit board has blown your lift won’t beep or have any indicator lights on the controller.
All stairlifts have revisions and redesigns on their circuit board designs and internal software. For example, The Pinnacle stairlift model does not have the same board as it did a few years ago. Even though the Pinnacle is the same model lift the circuit board and connecting wiring harness will be different depending on the year it was manufactured.
This is also the case with Acorn, Bruno and all other stairlifts. To illustrate this the two circuit boards shown here are for the Sterling/Handicare model 1000 chairlift. The green board on the left is just a few years different than the orange board on the right. Besides the color, the connectors are different as well as many other details.

Notable differences in the Acorn T502 & 130 T700 PCB upgrades including new transformer power supply from 15VAC to 28VDC, larger fuse 20A to 25A, ribbon cable to diagnostics display readout and top main terminal strip.
