AC200P lost power to 12V outlet

The 12V 3 amp RV outlet has lost power. I have been running a diesel heater on it for several months with no problem. The load is less than 30 watts.

The fuse on the plug is good. The device works with a different 12V source.

The 25 amp 12V outlet still works fine. Is there a fuse or a reset to get this outlet back on line?

Thanks

@hertfordnc There is one 12V/25A RV outlet on AC200P. Do you refer to 2 x 12V/3A (5,5mm Outlet)?

Sorry, it’s about nomenclature. I would not call the 25amp a RV outlet. I am referring to what we used ot call cigarette lighter outlets.

Anyway, those have lost power.

@hertfordnc Thanks for your explanation. It is recommended to contact after-sales support for repair.
