The Modern Fan Co. recalls about 1,300 Pensi Ceiling Fans.

The internal coupler that connects the down rod assembly to the motor can break and cause the fan to fall from the ceiling, posing an injury hazard to consumers. The firm has received four reports.

The recalled Pensi fans have model numbers beginning with or containing "PEN-AA-" or "PEN-GW-" and have an Aluminum/Anthracite or a Gloss White finish.

They were sold online in lighting showrooms, fan specialty stores and electrical distributors nationwide from August 2008 through July 2009 for between $400 and $530.

Consumers should immediately turn off the power to the fan to stop use and contact company. for assistance with model identification and a replacement coupler. Consumers are also advised to not allow anyone underneath the fan.
