We have a Subzero under the counter ice maker. During our hot summer days it really gets hot and slows the ice production down to a crawl. We thought we would install a cooling fan on the wall behind it or push an exhaust fan through the wall to the outside. But we are not sure which one would be the most effective. Right now we have drilled holes in the adjacent cabinet and I leave that door open and vent the heat into the room. Winter it's okay solution but summer no way. Which would be best and what type of fan system do I need?
I would 'push' and 'pull' with "muffin fans"
I would locate the 'push' side in the toe-kick area in the cabinet to the left and put the 'pull fan inside the top left wall (in the cabinet to the right of the icemaker) this should pull out the hot air at the top and supplement with relatively cooler air near the floor. Fan shrouding, plug in timer for night time operation (muffin fans are loud) and safe electrical wiring are left to the reader to implement properly.
