Replacing the Ryobi Drive Motor Controller Part No. 996508001

If you have a Ryobi RM480e Electric Ride-on Lawn Mower that has stopped moving forward or reverse, follow the steps in your owner's manual to troubleshoot. If the manual still does not give you a solution, one cause to think of is a broken drive motor controller. Several users have reported this to be the problem when their mower stopped moving. In my case, replacing the drive motor controller was the fix.
