Sometimes it will reset the control board the may fix the KitchenAid Refrigerator won’t stop beeping with Error Code PO issue. If it still doesn’t work then please check below for other solution.
This is what you need to do to stop the continuous beeping of KitchenAid French Refrigerator.
- Replace the Control Board when you see PO Error code.
- Or Replace the Power Supply Board.
So Control Board and Power Supply Board can cause the PO Error code. We suggest you to search them on Amazon or at your local improvement shop and replace them.
This advice may not be accurate. The PO code shows repeatedly because the control board itself is restarting itself continuously. Something is causing the board to reboot, which could be the board itself or something connected to the board. In my case, it was the freezer evaporator fan. You can test a LOT of things with NO disassembly and NO tools by getting the tech sheet for your model and putting your refrigerator in diagnostic mode.
When I used diagnostic mode to run the freezer evap fan, the whole system restarted itself again, so I knew to change the fan out.
I posted this information on Appliance Blog forum, which is the first Google hit that recommends unconditionally to buy a new control board to resolve the PO code, and Jake the shady admin on that site DELETED my comment and my account and then LOCKED the thread so people will continue to be misled. Complete scumbag.
Hopefully people dig a little further and find this comment before getting ripped off on an expensive, non-refundable part.
