Dometic Refrigerator Tips

[Howard O. Truitt]

Eric,
BB has a replacement for the fan. They were reasonable on price compared to
Camping World. It is a heavy built fan not a light plastic one.

Hi Ralph,
Thanks for the information. It seems the unit came back from the dead after I
shut off the
12 vdc to the back of the coach and then put it back in service. It took a
long time to cool
back down but then we keep having 100+ºF days which doesn't help. I don't
think the fan
located in the outside compartment is working anymore. Got any info on a good
replacement for this fan? Is it on a thermostat or should it run when I flip
the switch in the
panel next to the kitchen sink, regardless of temperature? Better circulation
through there
might improve cooling on these hot days.
