Errol for Model Number Whirlpool Model EV190N ( 190NXSN01 ) UPRIGHT FREEZER EV190NXSW01 I ordered a replacement defrost timer w1082278 and received it a week ago. I did not receive installation instructions explaining where to connect the black wire to which of the 4 terminals. the old timer 1115416 had a tab on the metal housing to connect the green wire ground and it had two black wires connected to #2 pink and #3 red. I taped off the green ground wire and connected the black wire on the new part to No. 2 terminal ( pink ) by my best guess. The freezer operates but will not get below 32 degrees (F). This is what had started happening with the old timer.
Answer Hello Errol, The black jumper lead goes on terminal number 1. The issue you are having does not sound like an issue caused by the defrost timer. You should check the frost pattern on the freezer coils. If there is an iceball where the lines come in through the back wall of the unit, there is a Freon loss. If there is no frost at all there may be no Freon in the sealed system at all or, if the compressor is hot, there could be a sealed system restriction. If there is frost built up heavily, the unit may have a defrost issue. Read More... Answered by AppliancePartsPros.com | Friday, June 1, 2018
