Please make sure to click on General above and select the correct appliance type first.

Brand: Samsung
Model Number: RF22K9381SG
Main Symptom: Control Panel Locked
What happens & when: Control panel on door lights up and shows temp, but all functions are locked, so no water, no ice, no adjusting temp. Resetting “lock” instructions does not work (holding for 3 secs). Could I need a new main control board?

Error Code (if any): no codes

I agree, it sounds like the main control. I don’t have the letters or number for your model number. if there are any let me know and I will look the part up for you.
