Dale October 03, 2016 for Model Number NNT196GZA/7A11A Was not defrosting. The heater was cracked from the ice buildup. I replace the heater tube and thermostat. The heater works if I manually turn the timer with a screwdriver. Once the heater comes on I turn the timer and the compressor and fan run and the refrigerator cools fine. I marked the timer screw (that I turn clockwise to activate the heater) and it never moves. I assume it has to be a faulty timer that the manual screw should rotate with the timer gear or am I wrong? Thank You
1 Answer Hello Dale. Yes, the timer WP4391974 is bad and will need to be replaced on the unit. Read More...

Jw August 31, 2016 for Model Number NNS207DH This is a old Norge refrigerator. the model # MAY be NN5207 instead of NNS (number 5 instead of letter S) The DH is definitely there on the plate, but online locators don't show that particular ending. The Serial # is DL3250443. The replacement part is defrost timer WP4391974. The question is the usual one -- does this model require the extra black wire to go to terminal 1, or 2? Can we choose the 6 hr cycle for this model?
1 Answer Hello JW. You should put the black lead on the number 1 terminal as labeled on the defrost timer. This wires the unit as a continuous run configuration. Read More...

Henry December 03, 2015 for Model Number NNT156GZA Purchased a generic replacement defrost timer from you all and I have no clue if I am cumulative or continuous?

Needed a whirlpool part 65702-1 but it is replaced my the expanded application unit 4391974 TIMER-DEF with more going on than is needed for my unit.

Sarah July 09, 2015 for Model Number Magic Chef Refrigerator RB23FA-3A We have purchased timer #4391974, but we do not know if our refrigerator is continuous run or cumulative. The instructions state for continuous, attach loose lead to terminal 1 and for cumulative, attach loose lead to terminal 2. This seems to be backwards from the answers provided to others, although no one has the same model we do. Wires are 1-blue, 2-yellow, 3-white and 4-orange. Thanks for your help.
1 Answer Hello Sarah. For your model number, you will need to attach the lead to terminal number 1 of the timer. Read More...
