The Frigidaire 318232621 Range Wiring Harness is a bundle and arrangement of the internal wiring of the range, which joins electrical power, control switches, heating elements, and safety sensors. It also directs power to the main inlet to other parts, like burners, igniters, to make sure that there is no fluctuation in signal and current. The harness is placed behind the control panel, and inside the chassis to ensure that wires are insulated and that they are organized.
