I just removed my refrigerator from my 1985 Vanagon Camper to clean it out
for increased efficiency.   Should I also open the combustion chamber and
give that a good clean (that square silver box with the window)?

I also noticed for the first time the fan (having never heard it before).  I
tested the fan and it worked by placing a 12 volt power supply to the
terminals of the fan.  I am thinking the fan is inoperable because of a fuse
or some other wiring in the vehicle.  Any suggestions?

Thanks,

Paul Borghese
