Amana Microwave Error Code P004

P004 is a self-diagnostic pass code specific to Amana microwave models .000, .003, .004, and .A. It confirms that the control board has completed its internal self-test and all monitored controller functions are operating normally. This is not a fault or error code requiring repair. Disconnecting and reconnecting the power cord will clear the code and return the unit to normal operation.

Yes, P004 indicates that the controller has passed its self-test, meaning no faults were detected. The unit is safe to use. Cycle the power to dismiss the code, and the microwave should operate normally. If you notice any other unusual behavior alongside the code, investigate further before use.

There is no repair cost associated with P004 because it is a pass code, not a failure code. The only action needed is unplugging and replugging the unit, which costs nothing. If P004 is appearing alongside other codes or persistent malfunctions, a service technician visit could range from $50 to $150 depending on your area and the nature of any additional issues found.

No repair is required for P004 since it is a pass indication, not a fault. To clear the code, simply disconnect the microwave's power cord from the wall outlet, wait a few seconds, and then plug it back in. The display should return to normal standby mode after the power cycle.

Yes, a power reset is the correct and recommended way to clear P004. Disconnect the power cord from the outlet, wait a few seconds, and reconnect it. This exits the diagnostic display and returns the microwave to its standard operating mode.
