Anything that circulates air in the fridge
and keeps ice from accumulating on the heat transfer fins helps. Interior fridge
fans are not a new idea. I just thought I would share what I did. On a piece of angle aluminum I installed four slow turning ultra-thin 80mm x 80mm x 15mm 12v computer fans and chrome grills. I cut out aluminum where the fan blade overlapped the angle aluminum. From those cut out bits I made fan-to-fan braces rather than install a second piece of angle aluminum. Corner braces were used to install the assembly into the fridge
, immediately in front of the heat transfer fins. Yellow speed control wires came with the fans. I snipped them off and insulated the ends with heat shrink tubing from Harbor Freight.
Colllectively the fans draw 0.2 amps. The wiring exits the fridge through the same hole as the thermostat sensor wire. I have them connected to a switch mounted on the galley, where I can switch them off before opening the fridge. I included a picture of the receipt to show vendor, model numbers, and prices.
These fans really help, even more so I think than the similar fans I installed to blow hot air out the exterior refrigerator
vent. They can barely be heard, if at all, inside the cabin. No more ice build up on the heat transfer fins and no more warm and cold spots inside the fridge. They have been installed for about a year now with no problems.
These fans and regular freezer ice removal have made the refrigerator
work MUCH better.
