  Katie ParkerJul 27, 2025
  If the batteries on your Invacare Wheelchair aren't charging, start by checking the cabling and replacing the fuse if it's burnt out. Defective batteries can also cause charging issues, so consider replacing them. To determine if the battery charger is the problem, use a battery charger you know is working properly. If your batteries still do not charge, send the defective battery charger to Invacare Service for repair.

Why my Invacare Storm 4 Wheelchair will not start?

  Henry LewisAug 7, 2025
  If your Invacare Wheelchair won't start, there are several potential causes. First, ensure the drive motors are engaged. If they are disengaged, engage them. Defective batteries can also prevent starting, so consider replacing them. A completely discharged battery will also prevent the device from starting; in this case, pre-charge the batteries. Check the main fuse if the power supply to the remote is interrupted. Inspect the cables between modules for loose connections or damage. Finally, the remote itself might be defective, requiring replacement.

  If the motors on your Invacare Wheelchair stop and won't restart, there are several things to investigate. A high motor load might cause the power module to lower the voltage; leave the mobility device switched on and let the power module operate, then charge the batteries overnight with the device still switched on. Also, check the fuse, and replace it if it's burnt out. Inspect the carbon brushes on the motor and replace them if needed. Finally, the power module itself could be defective and require replacement.

  Mason EllisonAug 22, 2025
  If your Invacare Wheelchair pulls to the left or right, it could be due to drive motors running asymmetrically. Try changing the programming to synchronize the motors. Also, check the air pressure in the tires and replace the inner tube and/or valve if necessary.
