Before initiating troubleshooting, the following equipment is recommended:
Multimeter, 20 gauge (min) wires to use as jumpers, and 12Vdc source.
Before applying power, stand unit upright for a minimum of 1 hour to allow compressor oil
to settle.
NOTE: Although, Dometic states on the packaging to always keep unit
upright, we cannot control how the carrier handles our boxes. This also
applies if the unit has been set on its side to affix any accessories.
If there are any questions, please contact our warranty and service department at 1-800-234-
8778 or 804-764-1313.
