Compared to an air conditioner, a swamp cooler has fewer moving parts, making it more susceptible to malfunction. Predictability is an advantage here because you’ll know exactly where to look if you run into any operational issues. Some of these problems are described in the following content to quickly fix the problem and get your cooling unit to start blowing cold air again.
Swamp coolers perform poorly in humid climates, one of the most common causes of evaporative cooler failure. Evaporative coolers can also fail for other reasons. Swamp coolers fail if the evaporative pads become saturated with water or the scale and debris build-up. Alternatively, the internal belt may break or come loose, in which case a replacement is required.
It’s not uncommon for swamp coolers to fail due to faulty wiring, which can cause the circuit breakers or fuses to trip repeatedly. Also, the fan motor may stop working, so it will be necessary to replace the unit altogether. Another reason your swamp cooler may not work is that the thermostat may be set too high, so the team does not need to blow cold air to maintain that high-temperature setting.
If you don’t have proper airflow, your cooler won’t be able to perform at its best. Open a few windows to allow warm air inside your home to escape. Swallow more excellent airflow can be influenced by closing doors to rooms that are not being used and opening windows in other rooms where a cooler temperature is desired.
If cold air isn’t coming out of your swamp cooler, one of several issues could be to blame. One possibility is that you have the thermostat set too high, which can be fixed by lowering the temperature. If your unit doesn’t turn on, you may have blown a fuse or tripped the circuit breaker. It’s possible you’ve got a wiring problem if the fuse or circuit breaker trips again after replacing it.
You can tell if a short-circuit has occurred by looking for frayed wires around the fuse or the circuit breaker and small black spots. Another possibility is that you’re dealing with low voltage, making your unit perform at a lower level. Additionally, the evaporative pads may have become clogged with scale and debris, necessitating cleaning the evaporative pads in this case.
If your cooler has a musty smell, your evaporative pads likely have mildew or stagnant water. Check your places regularly and replace them if they need to be. Additionally, the water in your sump may have stagnated and require draining and cleaning.
You can add a teaspoon of vinegar to your unit’s water to keep it clean for a more extended period. Using vinegar alone may not be enough to eliminate the musty odor, so you may want to try using a bleed-off kit, which removes some of the water and replaces it with fresher water automatically.
