That small 3A fuse protects low-current 12V circuits like the controls, interior light and door switch. Since Norcold mentioned door alignment, check the door light switch and its wiring for a short, and unplug the interior light and fan leads one at a time. If the fuse still blows with those disconnected, the board is likely the cause. The 637082 power board is in stock.
