After looking at the replacement part for the BM23, I noticed the the fan that is in my cooler is the wrong one. The guard is missing too. I just repitched the blades so it blows on the coils. It should be moving more air than it is, so I will be ordering a new fan, motor and guard from bev air. Still managed to break the 40°F barrier. got down to 39.5°F. Slowly getting there.
