What to do if my SystemAir IV-50 EC motor does not rotate?
- WwallmonicaAug 5, 2025
If the motor of your SystemAir Fan isn't rotating, several factors could be at play. First, check the supply voltage and ensure it's correctly established. If the connections are faulty, disconnect the power supply and correct the wiring according to the circuit diagram. High ambient temperatures can also cause this issue, so verify that the correct fan is being used for your specific application. Also, check the control signal wiring and verify the signal value at the fan. Finally, if the temperature monitor has activated, allow the motor to cool down before identifying and resolving the underlying cause of the fault.
