Rehabbing a BM-23

[dooley]

By the shape of the fan blade, and the tube going up the tower, I would suspect that the fan should blow air across the condenser, and blow colder air up the tower towards the faucet.
The replacement fan I got locally pushes the air (toward the door), pulling air down the flexible tube across the condenser.

What direction should the fan be rotating, blowing or drawing?

Mine draws air from the fridge into the condenser box and blows it out of the corrugated tube into the tower.

Back in August, I reversed the guts of the fan to blow onto the condenser coils and up the tube to cool the faucet. Had a problem that the old fan blade chipped and rattled. Bought a new replacement (plus a spare) for a couple bucks.
The unit runs great, beer is perfect.

Thanks for all of the varied posts, a wealth of information here.
