Re:Normalize fridge temperatures by installing a PC fan

Author said the fridge was 10 years old - it should have a fan on the bottom coils - but if the coils are on the back, then that'll take more than one PC fan (I'm not even sure what you could use - maybe a couple of box fans?).
Also - for everyone else - be sure to keep your coils clean (there's a special brush you can buy that looks like an oversized q-tip mated with a pipe cleaner), and make sure there is proper space on the top/sides/rear of the fridge for proper airflow (usually 3-6 inches of room - varies based on the fridge, and sides - some sides need more room than others, usually back side and top need 6-8 inches of room or thereabout; sides less).
We use one in our RV fridge, since it often has to go from ambient to whatever we set it to, and a little circulation helps, especially if the fridge is packed. I keep a battery charger and some rechargeable D-cells. I'm extrapolating that the batteries last about a week-ish.
If the author's fridge is old enough to not have a fan for the interior, it probably doesn't have a fan on the exterior coils. Again, based on camping fridges, a quiet PC fan on the coils can make a noticeable difference.
