E Fault Code - DC voltage high - N510
NOTE
Electronic controls operate on 12 Vdc. 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 "E" or “C” fault code to display.
To troubleshoot an "E" or “C” fault, connect a charged 12 volt automotive
battery to the power board. If the "E" or “C” code clears, the fault was caused
by unfiltered dc power. If the "E" or “C” code does not clear, replace the
power board (see page 43).
Before beginning this procedure:
■
Make sure RV dc voltage to refrigerator is 10.5 to 15.4 volts.
■
Determine if the "E" fault code displays when the converter is the source of dc power.
Fault indicator displayed.
Voltage
higher than
15.4 Vdc?
NO
Correct incoming dc power distribution to
refrigerator. Power distribution must be
10.5 - 15.4 Vdc.
YES
See NOTE above to determine
and correct an "E" fault.
Check for dc voltage input
to power board terminals
12VDC and GND1.
