Replacing the USB Port

The USB port is typically replaced after a software update fails with the assumption the port is bad. There are multiple failure points in the circuit that can cause the update process to fail. Before replacing the external USB port attempt a software update using the internal USB port located on the control board. A short jumper wire connects the external USB port to the internal USB port, ensure it’s connected and intact. Corrupted, out of date or incorrect versions of the files on the USB drive can also cause an update failure.

To avoid electrical shock or property damage, move the power switch to OFF and disconnect power.
