The portable warning system for cooking appliances includes a mechanism for detecting the state of the appliance through a current sensor for electric appliances or a sensor assembly operatively connected to an actuating member positioned adjacent to a range knob. The state detection mechanism emits a signal that indicates a change of state of the range from an "off" position to an "on" position and vice versa. A range transmitter unit is operatively connected to the detection mechanism and detects the signal from the detection mechanism. The range transmitter unit transmits a wireless communication to portable warning receiver units located throughout the building that the range is activated. The portable warning receiver units are configured to communicate different warning signals to an occupant when a range is on.
