A combination drying unit has a towel roll rotatably held within a housing. By activation of a switch, a motor drives a drive roller that has an idler roller biased thereagainst for advancing the paper towel stream through a first opening of the housing. A blower is also disposed within the housing and blows a stream of air through at least one second opening on the housing. A sensor activates the motor and the blower. A sensor detects the presence of a towel stream and deactivates the motor until this sensor no longer detects the paper towel stream. Another sensor detects the absence of a towel stream, deactivates the motor, and increases the length of operation of the blower upon activation of the switch. This sensor also illuminates a service light indicating either a jam condition or an out of paper condition.
