Anyone use a small fan in their fridge to help stabilize the temperatures.
I have seen a battery powered one. Any comment on their effectiveness. |

Our built in tended to be colder waaay down there and warmer in the top far end (of course!). After the fan, the temps were the same everywhere and less cycling. Also a longer time between defrosting. Here's what I used. Get a computer CPU fan. Take the actual fan off. I left the connector on it and wired in the mating connector from an extension. It's wired directly, thru a fuse, to the house bank. Those fans draw around .06 to .1 Amps, so a max of 2.4 Amp Hours per day. Use a small L-bracket to mount or even a twist-tie to hang it from something. Rick S/V Final Step http://www.morelr.com/coronado/ |

Anyone use a small fan in their fridge to help stabilize the temperatures. I have seen a battery powered one. Any comment on their effectiveness. I have a small fan that lasts a month (continuous duty) on one D-cell battery. I bought it for $12 from an on-line store that caters to the RV crowd. I can't recall the name of the store. This is so cheap and easy that you could try it and, if you don't like the battery option, at least you would know how it worked before going through the effort to wire it. For us, the battery power was not an issue and the results were well worth the cost. Dave |

Practical Sailor did a review of a rather expensive (to me) fridge fan (Tube Fan, US$135.00) in the January 15th, 2004 (Vol. 30, #2). It draws only 1.2 amps at 12 volts. Stainless steel fasteners, non corrosive construction. They found it to be very effective, evening out internal temperatures and increasing the efficiency of the system (in this case a thermoelectric unit). http://www.offshoresystems.us/fan2.htm -- Ken Heaton & Anne Tobin Cape Breton Island, Canada kenheaton AT ess wye dee DOT eastlink DOT ca |

seal the hole with a little bit of white caulking which you probably
already have - forget the foam - it's messy and hard to control for a small hole - like a 1/8" diameter which is all you'll need for 2 small wires and some protective insulation tubing.

Jesus - $135.00 ?? Was this for the space station.
I bought a small 12 vdc fan (1.5" square) from a computer parts place - ball bearings, rated at 50,000 hours life, uses 0.08 amps - for $1.99. That's 1.92 AH for 24 hours. For the $133 I didn't waste - we (couple) can go out to dinner in mexico 19 times - that's something like 3 chicken enchiladas, rice, beans, chips, and a beer for 33 pesos - $3.00 US each - plus $1 tip - $7 total x 19 nights = $133 What's wrong with those idiots at "Practical" Sailor - 19 years ago when I was a novice cruiser - they were idiots even then.

Any words of wisdom on an easy way to do it? The easiest way to run the small fan wires through the box wall is to use the same hole that the refrigeration tubing runs through. Use a blunt tool to open up a small hole adjacent to the existing tubing, be careful not to scratch the tubing or vacuum panel insulation if so equipped. Do not drill holes through box or insulation if the box has vacuum panels insulation. If, it is not possible to follow the existing tubing select an area inside and outside the box, free of other tubing and electrical, that is convenient with good access. Then using a 1/8 inch drill-bit, drill a hole through the box's liner and insulation. Normally a standard drill will not be long enough but it will start the access hole. If you do not have a long drill-bit to complete the hole cut a straight section of a wire coat hanger with wire cutters. The sharp end left by the wire cutters will act as a cutting edge to complete the hole even if there is a wood bulkhead to cut through. Once the 1/8 in. pilot hole is open at both ends, a drill slightly larger than the wires can be used to increase the hole size. Silicone sealant can be used to fill and seal the hole after the wire is installed. When refrigerator or iceboxes are to be constructed I always recommend that the builder consider installing an access tube through the insulation for future wires. There are several reasons you might want or need a small fan in a refrigerator to: Tumble the air when there is insufficient natural air movement. Achieve a forced air spillover dual temperature box with a separate thermostat. Lower the temperature of a shelf located above the evaporator cooling coil or to move the warm air in a long shallow box to the evaporator. Increase the overall efficiency of an incorrectly sized evaporator by changing part of it from a static to a forced air heat exchange.

The refrig lines are a bit hard to get to. Looking at it, I also found that the drain line goes into the bilge. Arrgh.
