Description
This is a BRAND NEW Lennox/Armstrong/Ducane Defrost Sensor L68F-31 3/8" 80L. The part # is 17W11 (also 17W1101 & 100503-04). Opens at 29 degrees. This sensor mounts on a 3/8 Copper line in the HP. When a defrost sensor goes bad the heat pump will often turn to a solid block of ice (although this is not the only ice causing failure). Thanks for looking and good luck! .
