During normal use of your stair lift it is likely the main batteries will need to be replaced or the lift will display a fault error code. The guide below is a list of the Acorn stair lift error codes and most common things to check. If your lift is beeping or making a chirping noise it’s an indication your lift is not receiving a charge voltage and needs immediate attention. For help with these issues give us a call at 866-721-6004. We serve the Northern Virginia, DC and Maryland area.
Acorn stair lift codes models 120/130
Explanation of the codes, what they are telling you and what to do.
Stair lifts have many features to keep you safe and operational at the same time. If your lift stops working the codes on your lift can tell you what the problem is. It is important to note the codes flash in sequence of a letter then number. Here are the most common codes for the Acorn 120 and 130 stair lifts.
C1- This code is normal, it’s to let you know the batteries are charging.
C4- The internal lift batteries are fully charged. All Acorn lifts run off the batteries, the household power is supplied to charge theses batteries.
C5- The charger is connected but not charging. This is a battery fault problem and requires a service call. The batteries will need to be replaced and the lift charging circuit should be checked.
A1- Stair lift is beeping, the lift is not parked on a charging station. The A1 code is telling you the lift is not charging. Move the lift to a charging point. If the lift doesn’t stop beeping check the power supply.
Normal operating codes.
A2- This is a normal code when the lift is traveling up with the armrest switch.
A3- Is also normal and should be on when the lift is traveling down using the armrest switch.
A4- Normal and the same as A2, lift traveling in the up direction but is shown when using the remote control.
A5- Normal and the same as A3, lift is traveling in the down direction but is shown when using the remote control.
E Codes – Indicate an Error and is typically a problem that can be easily fixed.
E1- The footrest safety edge has been activated in the up direction, check footrest for an obstruction.
E2- Is also the footrest sensor but in the down direction, check footrest for an obstruction.
E3- The safety edge on the carriage has been activated in the up direction. The safety edge is different from the footrest sensor. The safety edge is on the carriage of the lift and wraps around the stair lift rail. The top safety edge will have a key switch and battery switch located on the front.
E4- This is also the safety edge on the carriage but for the down direction. It will look like the top safety edge but without any switches on the cover.
E5- The seat is not in its normal operating position. Try swiveling the seat to reset the sensor.
E8- The batteries are low and need to be charged.
E9- The lift key-switch is in the off position. Check the key-switch is turned to the on position.
F Codes – Fatal Error codes indicate a problem that will need a stair lift service tech.
F1- Board relay fault, you will likely need a replacement board call for service.
F2- Brake fault will usually require a service call. Try turning the lift off and resetting.
F3- Motor fault call for service.
F4- Over current to the motor fault. Recommend service tech.
F5- Battery fault, try parking the lift on a charging contact.
F6- Over limit means the lift went past the normal limit and shut off. Try hand winding the lift away from the end of the track. Before running again it will need to be determined why the lift went too far. Recommend service call.
F7- OSG or over-speed governor, the lift should be check by a service technician.
F8- System lock out, try turning the power off and resetting the lift, call for service.
H Codes – Hardware Faults – Lift will not Operate Requires Tech
H1- Multiple error codes likely SW-1 safety short to ground, requires service
H2- Multiple error codes SW-2 safety short to ground, requires service
H3- More than one error has occurred
H4- More than one error, safety device fault
Stair lifts are machinery and should always be serviced or repaired by certified lift technicians.
The Acorn lift operates with the use of two stairlift batteries. The batteries are internal and should only be serviced or replaced by experienced stair lift technicians that are familiar with the Acorn stairlift.
The batteries on the Acorn 130/120 receive a charging current from an external power supply. This unique transformer has an output 15VAC 2500mA and is a plug-in style transformer that should also be checked when your lift is serviced.
