Why is my BIG ASS FANS COOL-SPACE 300 motor overheating and shutting off?
If the motor overheats, shuts off, and restarts, it could be due to an extension cord with too small a gauge or obstructed inlet air. Try replacing the extension cord with a heavier one and ensure there is at least 3 ft (0.9 m) of clearance for inlet air. If the problem continues, consider replacing the motor.

Why is the floor wet near my BIG ASS FANS COOL-SPACE 300 cooler?
If the floor is wet at the side of the cooler, the water inlet hose might be loose at the supply hose or at the bulkhead fitting. Tighten the connections and/or replace the hose washers.
Why is water overflowing from my BIG ASS FANS COOL-SPACE 300 Fan reservoir?
If water is overflowing from the reservoir or spitting through the fan, it could be due to several reasons: a loose float valve hose, water pressure that's too high (exceeding 120 PSI), or a float valve that's not properly seated. Try tightening the hose connections and/or replacing the hose washers. If the water pressure is too high, reduce it by adding an inline reducer. Also, check all hoses for leaks.
What to do if there are too many dry streaks on the pads of my BIG ASS FANS COOL-SPACE 300?
