Mike for Model Number Z1SS480NMBS Replaced WR55X10286 main board with WR55X11130 after the unit stopped cooling. Immediately noticed main display at top of refrigerator not lit while produce / vegetable bin displays were on. Upon pressing any button on the main display it come on for a while. Wondering if there was any jumper or something to make the main display come on when door opens. Also when using a calibrated thermometer it reads -15 in the freezer and 40 degrees in the reefer when the main display reads 1 degree in freezer and 34 degrees in the reefer. Is there some way to calibrate the display? Also it will not allow any temperature in the reefer side below 34 degrees?
Answer Mike, There would be no jumper wire that would allow the display to come on when the door is open but you could test to make sure that there is not an issue with the door switch. There is also no calibration of the display board. Read More... Answered by AppliancePartsPros.com | Thursday, November 2, 2023
