Troubleshooting for Mobile Coolers

PROBLEM

CAUSE/REMEDY
Cooler will not turn on Check that the unit is plugged in properly
Check that the unit is turned on
If the unit has a timer be sure it is off
If the unit has a GFCI plug be sure the light is green-If it will not reset plug needs to be replaced
If the unit is plugged into a GFCI outlet be sure the outlet is not tripped
Unit may need a new ON/OFF switch 
Cooler does not pump Be sure the pump is turned on
Be sure the water level is not low especially important on automatic models
Be sure the pump connection is connected
Be sure the hoses are connected and free of debris
Pump may be defective and need to be replaced
Pump switch may need to be replaced
Fan does not operate Be sure the fan function is on
Be sure nothing is obstructing the fan from turning
Be sure the fan motor connections are connected
Fan switch may need to be replaced
If fan runs slow upon start up the capacitor may need to be replaced
Fan motor may be defective and need to be replaced
Oscillation does not operate Be sure the oscillation/swing function is turned on 
Be sure the oscillation connection is connected
Oscillation motor may be defective and need to be replaced 
Oscillation switch may need to be replaced
Water leakage Be sure drain plug is tight
Make sure cooler is level
Be sure the unit is primed by running pump only for several minutes to allow media to saturate
before turning on the fan function. 
Inspect tank for cracks or breakage
Be sure all hoses are connected with no cracks, holes, or scaling that may disrupt water distribution
Be sure there is atleast 4 inches between the back of the unit and a wall or other obstruction.
An obstruction in the rear airflow could increase the air velocity through the sides and cause water 
to be released into the airstream.
Be sure there are no obstructions in the spreaders/water distribution plates causing the water pool
or not flow over the media properly. 
Be sure the the rubber washers are in place/not worn if leakage is from the hose adapter 
Water intake/overflow Be sure the float valve is adjusted at a 45 degree angle (not straight out or up and down) and adjust
if necessary by loosening the wing nut, adjusting, and then tighening wing nut 
If the float valve is broken or the bulb has taken on water it will need to be replaced.
