If your Bosch refrigerator looks completely dead or the display and buttons have stopped responding, the most likely culprits are the dispenser control board or the user control and display board—inspect those boards for burn marks and obvious damage first. Next, rule out an incoming power problem by confirming the plug is fully seated, the outlet is live, and no breakers or fuses have tripped. A loose or damaged wire harness between the panel and control board is a common follow up cause, so check connectors for snug fit and visible wire damage. Sometimes a simple power reset restores operation after a surge or outage, so unplug the fridge or flip its breaker off for a few minutes and try again. The main control board can fail, but that is less common; test the more likely parts before swapping the main board.

Ensure plug is tightly pushed into a regular electrical outlet and the outlet is supplying power. Using a ground fault outlet for a refrigerator is not recommended. Confirm that no circuit breakers have tripped or fuses have blown.
Highly Likely
03 - Bosch Refrigerator User Control and Display Board
If the refrigerator display appears completely dead, it's possible the user control and display board has failed. You should inspect the board for any burn marks and replace it if it appears damaged.
The wires from the control panel to the control board may be loose or have become disconnected. Make sure the wire harness connectors are tight. A damaged wire harness will need to be replaced.
Common
05 - Power reset
After a power surge or power outage, refrigerator operation could be temporarily affected. Full operation can sometimes be restored through a power reset by either unplugging the appliance's power cord for a few minutes and then plugging it back in or switching off the circuit breaker for the refrigerator then switching it back on.

06 - Bosch Refrigerator Control Board
If nothing is working on the refrigerator, it's likely the control board is defective. However, this is almost never the cause. Before replacing the main control board, test all of more commonly defective parts. If none of the other components are defective, consider replacing the control board.
