Says refrigerator side getting warm 54 degrees. Freezer side running zero.
Refrigerator temperature normal. Fresh food 36 and freezer 0. . Stated Monday afternoon. Left door open for 3 minutes to see if unit goes into liner protection and freezer fan runs on high. Works fine. Confirm damper/fan assembly in refrigerator working. . Air return clear. Run diagnostics test. Only thing that didn’t pass was temperature control panel to dispenser board communication. That failed. Did try my test control panel I carry in place of customers panel. Same results. Failed. Don’t really understand why temperature control panel talks to dispenser board when there is nothing on temperature control panel that controls anything on dispenser board. Refrigerator door switch is on side wall. Confirmed door switch is being activated by door. When door is one inch from closing, switch turns off interior lights. Currently have door switch taped closed. Did go ahead and do the system reset. . Thermistors passed testing, but then again you never know. Also is the picture of thermistor old style? Should I maybe upgrade them?

Cycle the compressor off, wait 4-5 minutes, then restart. I had one that was bugging me like this, and after several trips finally caught the compressor having a hard time starting up. Replaced relay/OL and solved the problem. The fact that the temperature is corresponding with the display, my assumption is that your thermistor in fresh foods is fine. Sounds like an airflow issue to fresh foods since your freezer side is holding at 0F. Freezer staying cold would rule out sealed system issue on single evaporator unit. Now the only issue is catching the problem when it is acting up! My two cents would be leaning towards the evaporator fan motor or the low voltage side of main board not supplying the DC voltage at all times. You can use the WR60X10074 motor which comes with the defrost thermistor attached. Would also recommend checking the defrost circuit and energize to make sure it is working properly.
Agree with you on the display and dispenser interface not having anything to do with the other. May want to ask customer to check at air vent in fresh foods for airflow if temperature gets warm again, of course the door switch will need to be held in when checking.
