A circuit for controlling power to the fuser of an electrostatic type reproduction machine in response to voltage levels across the fuser heat source as monitored by a transformer-rectifier combination. The transformer signal output is applied to an R/C circuit which controls a switching means in the fuser power line. When a preset power level is reached, the switching means triggers to interrupt power to the fuser heating source. A second R/C control circuit serves, following a time interval, to reset the switching means and resume power to the fuser heater.
