Sr" "Cl"/"Ac" "Re" Fault Code - Norcold 1200 Series Service Manual

"dc" "HI" Fault Code – DC voltage input to power board is higher than 15.4 volts
Before beginning this procedure:
Make sure RV DC voltage to refrigerator is 10.5 to 15.4 volts.
Determine if the "dc" "HI" fault code displays when the converter is the source of DC power.
Fault indicator displayed:
Check for DC voltage input
to power board terminals
12VDC and GND1.
Electronic controls operate on 12 volt DC. When an AC/DC converter is
used to supply DC power, the refrigerator circuit must be connected to the
appliance output terminals of the converter (filtered side).
If the refrigerator circuit is connected to the unfiltered side, the AC ripple
generated by the converter may cause a "dc HI" fault code to display.
To troubleshoot a "dc HI" fault, connect a charged 12 volt automotive battery
to the power board. If the "dc HI" code clears, the fault was caused by
unfiltered DC power. If the "dc HI" code does not clear, replace the power
board (see page 39).
