Atwood HE0801----helium fridge (no longer in production and parts are scarce)
12V at BOTH 3A fuses :H
12V DC at terminals J2 (12V POS) and J4 (Ground)
then should have 12V DC on both sides of 3A DC fuse
That would be the center vertical 3A fuse
THIS fuse is for ALL DC controls, display and light
Far left horizontal 3A is for the 120V AC circuit
Should only have 120V AC ...no DC
Far right horizontal 20A (25A) is for the DC electric heater
No display lights no interior light........NO DC Voltage
SO either fuse holder is not making contact if fuse is good
Or circuit board is issue
Did you plug AC power cord back in and check fridge function???
Reset for fridge is POWER ON/OFF button.........but have to have DC for that to work
Is it time for your medication or mine?
