If your Tappan refrigerator is not running and the display or dispenser controls are dead, the most likely causes are a failed dispenser control board or a loss of incoming power. Start by checking the dispenser control board for burn marks and test the outlet and circuit breakers to rule out a power issue. If the display still shows nothing, the user control and display board or a loose or damaged wire harness are frequent causes, and a simple connector reseat can often restore operation. After a power surge try a basic power reset by unplugging the fridge for a few minutes or switching the breaker off and on. The main control board can cause a total shutdown, but that is less common and should be a last resort after you complete refrigerator control board troubleshooting and verify the control panel is actually the problem.

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.

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 - Tappan 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.
