If you own an evaporative cooler, then you may need to indulge in some swamp cooler repair before you can start to use it every summer. The swamp cooler is a water-based device that cools the air by increasing the humidity. There are many complex parts to a swamp cooler, including the water reservoir, the air pumps, the electrical connections, and then fan. A lot of these items can become broken just by sitting in storage during the winter, so you will need to practice a few swamp cooler repair basics before you use it in the summer.
Locating the Problem
Once you get your swamp cooler out of retirement, you will need to perform a quick check of the machine. Plug it into a safe socket (which has a circuit breaker device installed), and then operate it for a full cycle. Examine the fan and the air pump, look at the water reservoir, and also check that there are no leaks coming from a particular area. If you locate any problems, shut off the machine completely, and unplug it from the wall.
A big problem with swamp coolers which have been left in storage is mold. Water can sometimes be accidentally left in the reservoir, or it may not be sufficiently dry before it is packed away for the winter. Remove mold by using a combination of water, vinegar, and bicarbonate of soda, and scrub away at the inside of the machine. In the future, it is a good idea to learn how to properly winterize your swamp cooler, as this will prevent some repairs from being necessary in the summer.
One of the most common problems with the swamp cooler is leaking parts. The location of the leak needs to be found, and then you can begin to work on it. Look for cracks and holes which are near to the leak, and also run your finger around the outside of the swamp cooler. Check that the inserts to the water reservoir are working correctly, and then look at the hard water build-up which has been created. You will need to look at possible scaling. If the pads on your cooler are worn, replace them for a new set before using the swamp cooler. You should then check the float valve. Water may be impeded from flowing into the reservoir by a broken valve, and this can cause leaks. Replace the valve is necessary.
Another common need for swamp cooler repairs is caused by the fan breaking down. This may be caused by a number of factors. Remove the fan from the cooler, and examine the condition of the fan paddles. If they are damaged or corroded, discard the fan and start again. Look at the motor and belt which drives the fan. Fitting a new belt can be easily done, but bad motors probably need a complete replacement. Check the fan is working correctly before reinstalling.
