Just returned from a fantastic time with my Westy camping in Colorado.  On
warmer days above 80 degrees, the refrigerator fan ran a lot, as it should,
but unlike in the past, it didn't go through a normal cycle.  Instead, it
might stay on 60 seconds, off for 2 seconds, back on for 5, off for 3, back
on for a minute, etc.  Do you think the thermostat attached to the rear fins
is going bad?  If so, do you know where I can get a replacement?

Thanks,
Paul in Colorado
