Bill for Model Number Admiral NT23B8SV A refrigerator repairman has replaced the defrost timer in our Admiral NT23B8SV with Whirlpool WP4391974. But it is not defrosting--the freezer is at zero degrees F while the fridge is at 65 degrees. He did *not* use the extra black wire, since all 4 terminals match the 4 correct wire colors in the plug. Directions say "For 6 hour continuous defrost cycle, attach loose lead to terminal 1." Does he need to do this to make the defrost timer work properly? How can the loose lead be attached when all 4 terminals are already taken?
Answer Bill If your referring to the jumper wire, it is used when there is a three wire hookup. The black lead attached to the timer will depend on your model and wiring diagram as to where it goes. The loose lead slides over a terminal and a wire is still able to be connected, and yes it has to be connected. Read More... Answered by AppliancePartsPros.com | Thursday, September 6, 2018
