SPD Error problem
This unit, as well as an Optima TL that we have, both recently developed a problem where, during spin-up, the RPMs start going up, then they bounce around erratically for a short while, and then the unit beeps with a speed (SPD) error, locking us out for 20 minutes until it resets. We have tried 3 different rotors in both machines but have not been able to isolate the cause of the problem. If you can coax it to start, it will continue running very well, but it's almost impossible to get to that point. I would appreciate any help. Thanks!
