Judy for Model Number bx20nl (very old model) Called Amana. After some searching they found my very old model number and the parts manual associated with it. They said, I need D7790402 for a defrost timer which has now been replaced by a newer version R0168027. However, the one installed currently has a green ground wire attached. What happened to the ground wire on the new version and if I'm using the wires on the refrigerator (which are white, yellow, black and blue) to connect it, how does it get ground if I'm not using that extra green wire?
Answer Judy,The new timer is all plastic and does not require a ground. The timer has L1 and N coming in on the most likely Black and white wires to run the timer and the other two wires would be power to the compressor and the heater circuits. Read More...
