Find out how to diagnose the most common issues for motors and what actions you can take to resolve them.
Motors may pause momentarily during starting and may reverse a number of times before a stable operating speed and direction is achieved. This is normal behaviour for this type of motor and is not a fault condition.
| Problem | Possible cause | Action |
| Motor does not turn | No mains power | Check mains power supply |
| Faulty connection | Check power cable connection | |
| Reverse function timed out | Allow motor to reset to CCW mode | |
| Thermal protection activated | Allow motor to cool down and Thermal Protector to reset | |
| Motor fails to start after multiple attempts or stops and starts often. | Fan diameter or pitch too large | Reduce load on motor |
| Motor runs in wrong or opposite direction | Black control wire not connected properly | Check the connection of the black control wire connection |
