GI6FARXXF05 Display Dead

[bobwire]

After a storm passed through a customer said their display went out. Lucky for them, the refrigerator still cools. From what I can see on the wiring diagram there is a Black/Green Wire running from the power board to the main board, then from the main board to the display. The tech sheet does not give me voltage information. On that wire, i have roughly 46V. I am doubtful this is supposed to be 46V but I'd like to make sure before I order a power supply board. Thanks!

check power supply board for out voltage P2-1 to P2-2  

check voltage at dispenser board  J2-4 rd-bk  ( J2-5 yl-bk comm wire )   J2-6 bk-gn   14vdc at 4 n 6

I have 46 VAC at power supply board at P2-1 and P2-2

[bobwire]

should either one of these have 46 VAC?

Did you try measuring dc voltage.  check voltage for center mullion .

Should be 14 dc 

or cycling power on n off

There was no DC voltage which is what I was expecting. So I flipped over to AC and had 46 VAC. If it should be 14 VDC then that power supply board is fouled up. I'll order that. Thank you very much for your help Ivasquez11. I'll let you know about the result.

I felt the mullion and it was stone cold. I checked for 14 DC and the UI board and had nothing. I changed the power supply board and still had 46-48 VAC and the black/red wire and the black/green wire. However, the display works now... Would love for it to have made better sense. I checked the mullion wires at the UI board again after changing the power supply board and still had nothing. Oh well. Thanks for the input
