Chris for Model Number RSG257AARS I have the same issue that the user: Nance, is describing. I purchased a new display and it did not solve the problem. The display began flashing 88 88 after a City power outage and has not reset. Display is locked, water will dispense, but no buttons will function. I tried turning the power on & off from the breaker, as well as unplugging several times with no luck. Any tips are appreciated!
Answer Chris, Try to press and hold the ice off button for 3 seconds and see if the unit will start working again. If this does not work then it would most likely be an issue with the main control board. Read More... Answered by AppliancePartsPros.com | Friday, December 3, 2021
