TROUBLESHOOTING
Before calling for service, try the suggestions below to see whether you can solve your problem without outside help.
PROBLEM POSSIBLE CAUSES RECOMMENDED SOLUTIONS
The evaporative air
cooler will not start
The evaporative air cooler is unplugged. Make sure the power supply cord is plugged into
a grounded 3-prong outlet. See the “Electrical
Requirements” section.
The fuse is blown/circuit breaker is tripped. Check the house fuse/circuit breaker box and replace
the fuse or reset the breaker. See the “Electrical
Requirements” section.
Power failure In the event of a power failure, the evaporative air cooler
will immediately stop. When power is restored, the vent
louvers will close, then the evaporative air cooler will
beep and automatically resume operation at the previous
settings after approximately 30 seconds.
The water tank is not in the proper position. Securely seat the water tank in place.
The evaporative air
cooler is not cooling the
air properly
Airow is restricted. Make sure there are no curtains, blinds, or furniture
blocking the front of the evaporative air cooler.
The water tank is empty. Fill the water tank and be sure Cool mode is on. For
added cooling power, add ice cubes to the water tank,
or use the ice packs (on some models).
The air lter is dirty. Clean the air lter.
The relative humidity in the room is too high. The cooling function of the evaporative air cooler is most
effective if the relative humidity level is below 75%. For
added cooling power, add ice cubes to the water tank,
or use the ice packs (on some models).
The evaporative air
cooler cycles on and
off, or the fan does not
blow at a consistent
speed
The Mode control is set to Natural. This is normal. For a steady, consistent fan speed, set
the Mode control to Normal.
