Kim for Model Number HDS7152U/03 What are the proper voltages for the x2/x3 control board pins? Do the relay and control/display board need to be a matched pair? In other words, will a new control/display board work with an original relay board? Thank you again.
Answer Kim, Remove the connector on X2 and test pin 1, 4, 6, 8 to ground. Pin 1 should show 1.5 VDC, Pin 4 should show 5 VDC, Pin 6 would be 8 VDC, and pin 8 would be 32VDC. If you have proper voltage then the display will be the issue and if there is not proper voltage then the issue will be with the control board. You do not need to replace both to get the unit working. Read More... Answered by AppliancePartsPros.com | Monday, February 21, 2022
