Amana air conditioner display and controls are unresponsive; buttons do not change settings.

Safety first: Unplug the unit before removing the front panel.

Steps to restore control response:

• Check for lock mode: Many Amana units have a lock function. Press and hold the Lock or a specified button combination (see manual) for several seconds to unlock.
• Power reset: Disconnect power for 5 minutes, then restore and test the controls.
• Inspect ribbon cable: Remove the front panel and check the flat ribbon cable between the keypad/display and main board. Reseat both ends.
• Replace display board: If the cable is good but controls remain dead, replace the user interface/display board with the correct Amana part.

Do not spray cleaners directly on the control panel; moisture can damage the keypad membrane.
