John,
I think we have the same fridge. My fan does not run at all. Some have said there is an inline fuse and I have not found it.
I also tried to figure out how to force the circuit on the fan by bypassing the thermostat that starts the fan and closing the circuit manually. Still the fan does not operate. The fridge seems to cool just fine, but I too belive that if the fan worked, it might cool better.
I read that you swapped fans. I am thinking that perhaps my fan is bad and am interested in what fan you chose to use. Any info?
Also off subject, I read your thread on the shower with no water and my '03 Bambi is the same! Problem is that they used a different shower head. I am next going to test the shower with the city water connection, but it sounds just like your problem.
Eric
