The present invention discloses a power failure compensation method for a laundry room machine that includes a payment device for collecting a payment for operating a laundry room machine, and an interface for communicating with a communicator. The method includes: a) detecting power failure by determining whether or not a pulse generated from an AC (alternative current) power is interrupted for a predetermined time; b) storing compensation data having information about a state of a laundry room machine when power failure occurs; and c) operating the laundry room machine according to the stored compensation data when the power is supplied again.
