For Whirlpool Supply, Power (Part Number: AP4076255)

Hello, I have a Jade refrigerator RJRS4270D and it has completely stopped working. I checked the power supply and the unit has power. I was told its either the power supply board AP4076255 and or the compressor board AP4008850. Anyway to determine one or the other or do I need both? I was looking at the diagram and they appear to be behind the panel directly in front when you remove the top cover, correct… Please let me know. Thanks,

Paris for Model Number RJRS4270D

ANSWER Hello Paris, Yes both boards are located behind the upper panel. If you have displays on your controls you can turn power off and close both doors. Then turn power back on. The unit may be in showroom mode. To test each board to find out if it is sening proper supply, check the power supply board red to white and you sould have 120vac. Then you would test BLK/Rd and to Blk/Grn and should have 26vdc and BLK/wht to blk/grn and have 12VDC. You could also check on main control to the JP11 connector for the same values. You can also check on the Compressor PCB to see if it is getting 120vac across red to white. Check JP10 connection on main board for 12 vdc between pins 1 and 2. If all voltage to the Compressor board are correct but compressor is not getting voltage then it is a bad compressor board. If the power is coming to the supply board but nothing out then the supply board is bad. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
