My electrical components are sitting directly below my refrigerator. I sealed all the necessary areas and installed vents with 120 mm computer cooling fans to force cool air across my electronics and up across the back of my refrigerator area, then exhausted through my roof vent with another fan.
I may be misunderstanding this statement, but it sounds like you have opened up vents between the bottom of the refrigerator and electronics beneath it. This is a very bad idea- the base the refrigerator is sitting on must be sealed and vented out the side- assuming we are dealing with a standard gas/electric model. LP gas is heavier than air.
