Atwood Refrigerator Error Code CHECK+AUTO+GAS+AC+DC ON (Open Fuse)

This condition means fuse F3, the controller fuse on the main control board, has blown open. When F3 fails, the controller loses power and the refrigerator cannot operate in any mode, which is why all mode indicators light up simultaneously. The fuse must be inspected, and the root cause of the failure should be investigated before replacing it.

No, the refrigerator will not operate in any cooling mode while F3 is open, so food safety becomes a concern if the unit is not repaired promptly. Do not attempt to bypass the fuse, as it is a critical protection device for the controller board. Address the fault before relying on the refrigerator to store perishables.

No, resetting the unit will not clear this error because the fault is a physical hardware condition: fuse F3 is open and must be replaced for the controller to function again. Cycling power or performing a reset does nothing to restore a blown fuse. The fuse must be physically inspected and replaced before normal operation can resume.

Replacing fuse F3 on the controller board is a task that a knowledgeable DIYer can perform, provided they are comfortable working with appliance control boards and using a multimeter. The key steps are locating F3 on the controller board, confirming it is open with a continuity test, and replacing it with a fuse of the correct rating. However, if the replacement fuse blows again, a deeper electrical fault is likely present and professional diagnosis is recommended.

If the fix is simply replacing fuse F3, the cost of the fuse itself is minimal, typically just a few dollars. If the controller board has sustained damage or a downstream component has failed and needs replacement, repair costs can range from roughly $50 to $300 or more depending on parts and labor. Having a technician diagnose the root cause before purchasing parts can help avoid unnecessary expenses.
