Pool Rover S240 won't go in reverse

Bought my Pool Rover S2-40 last year and it worked great all season. Near the end of the year, the cord got majorly tangled and ended up breaking the outer cover of the cord. Eventually the cleaner stopped working. This year bought a replacement cord. Had to jury rig it to get it to work as it wasn't exactly the same. Now the cleaner goes great in one direction but you hear the controller "click" and then the motor will not reverse. I have check the motor and it turns freely in both directions and there is nothing blocking the external outlet/flap. They more freely. Any ideas how to get it to go both directions? Is there an easy fix inside the controller?
