Description
The Lennox 71L20 Wiring Harness is an essential part that links the control box of your furnace to the gas valve. It works like electrical cables that connect these two parts to relay signals that control the amount of gas and the efficiency of your furnace. This wiring harness is intended for Lennox furnaces only. A bad wiring harness can cause many problems with your furnace, such as not heating properly, not igniting, or just shutting down. Performance of such work demands replacement of a damaged wiring harness with a new one, compatible with the rest of the furnace components.
