It may just need to be replaced. This is most likely a defective motor. It may occur straight out of the box, or after using for awhile.
Troubleshooting techniques:
1) Unplug and reconnect the lifter cord to the GN wireless system. Try turning the headset on and
off to test.
2) Adjust the lift level switch from “-” to “+” and test the headset.
If there are no changes after trying these simple steps, then replace the lifter.
