It is a full-time satellite of Mayagüez-licensed WORA-TV (channel 5) which is owned by Telecinco Media Holdings.

WRFB's transmitter is located on Cerro Marquesa in Aguas Buenas; its parent station maintains studios on Ponce de León Avenue in Santurce, with additional studios at the Guanajibo Building in Mayagüez.

On June 15, 2017, WRFB sold for over $600,000 to Telecinco, Inc. through subsidiary ERA International Corporation, and after the transaction with a $30,000 deposit had been made by the buyer, this became a sister station of WORA-TV in Mayagüez.

Due to the passage of Hurricane Maria, WRFB went off the air on September 20.

On June 12, 2009, WRFB signed off its analog signal and completed its move to digital.
