Swamp coolers are examples of evaporation heaters. They are popular in hot, dry climates because they throw cool, moist air through a house. Swamp coolers are not complicated pieces of machinery: they are essentially fans that blow air through pads soaked with water.
The first step is to take off the old swamp cooler meter, and install a new one. Open up the back of your swamp cooler by unscrewing the case. You should be able to reach inside the swamp cooler, and locate the motor. This may have another case holding it in place, and you will need to remove this if it is so.
