What to do if ERR 3 is displayed on AvantaPure AC Power Distribution?
- KKimberly MathisAug 1, 2025
If the AvantaPure AC Power Distribution controller doesn't know the camshaft position, wait two minutes for it to return to Home. The hourglass should flash while the motor runs. If the camshaft isn't turning, check the motor connection, wire harness, optical sensor, and motor gear engagement. If it's turning for over five minutes, ensure the optical sensor is correctly placed and connected, the camshaft is properly connected, and no debris is blocking the cam slots. If issues persist, replace the wire harness, motor, optical sensor, or controller, in that order.
