1. The capacitor is improperly
connected or not connected at all
(single-phase fans only).
1. Check the connections inside the junction box.
The capacitor must be installed according to wiring
diagram.

(RSV 400/450 only).
1. Phase sequence in the power to
the fan is reversed.
1. Swap two phases in the junction box.
The fan is vibrating vigorously. 1. The motor shaft is damaged.
