Adding fan inside refrigerator

[Richard Kollmann]

Look at Air tumbling Fans These fans must have their own very small fuses. They are normally 10 to 20 CFM fans and powered anytime refrigerator circuit breaker is on.

I used a Pulse Width Modulation speed controller form Ebay. Negligible cost.

I have computer fans in fridges and freezer, that run continuosly, get a rectangular length of PVC downpipe app 100mm by 45mm, you need to set it up so it sucks from the bottom of the chamber, hot air rises cold air sinks! You need to load your frig and freezer chambers so there is air flow at bottom and the fan just circulates from bottom to top.
Ive never had frozen tomatoes or lettuce in my chest frig!

The fan is mounted where the "exit" of th epipe is and sucks air from the low pipe and spills it over everything else in the fridge. Makes a big difference in evening out the cooling. The fan runs 24/7, when the fridge circuit breaker is turned on. I think the fan is rated at 0.15 amps?

I am amazed that 90% of comments are about fixing a fan rather than the benefits of this simple addition. My computer fan was a game changer. I had an evaporation plate one size too small, and could never go below 9°, and with long compressor times. Putting the fan in was like magic. Down to 5° and long pauses between compressor "on". There is literally no investment I made in 40 years of cruising with a higher cost benefit ratio.

following. We have a refer box and a separate freezer...both cooled via holding plates. But the temp is definitely stratified. The fan idea sounds like a game changer.
