How to Remove a Squirrel Cage Fan From a Swamp Cooler
To dismantle the fan, first unplug the unit and lay it face down. Then, remove the stand from underneath. Look for a screw in a small indent in the back. Gently unscrew both screws to remove the back cover. To remove the squirrel cage, wiggle it downwards to slide it off. You may have to squeeze the center grille to open it up.
Oiling the bearings
The two bearings of the squirrel cage fan on your swamp cooler should be oiled as part of preventative maintenance. If you fail to do so, the fan will either seize up and stop spinning or it will make a terrible noise. If you are unsure how to do this, you can use a zoom spout bottle of oil, which comes with an extender. Pour a small amount of oil into the bearing holes and fill the bottle to the brim. The swamp cooler motor will turn the caged fan, which blows cool air into your home.
Once you’ve completed this step, you can reinstall the panels to the cooler. To do this, place the water tubes above the pads. After oiling the bearings, put the cage back together and tighten all of the bolts. If your cooler has an evaporative cooling system, it’s important to turn on the water shutoff valve and the circuit breaker. If the cooling system does not have water flowing through it, the problem may be with the water pump.
Checking the tension of the fan belt
Checking the tension of the fan belt when disassembling a swamp cooler is essential. An improperly tensioned belt can make the fan spin freely but also cause overheating. In order to prevent this from happening, it is important to tighten or replace the belt periodically. You can easily check the tension of the fan belt by simply moving it. The motor sheave is part of the pulley system that pulls the belt. If the sheave is loose, you may experience overheating. If this occurs, you will have to shut off the swamp cooler.
Besides checking the tension of the fan belt, you should also check the voltage. You can find this information on the side of the motor. If the voltage is too high, the motor will overheat and damage the circuitry and wiring. To avoid such an accident, you should ensure that the wiring is properly installed and secured. It is vital to ensure that the swamp cooler motor runs smoothly and does not break down because of a bad switch.
Replacing the blower pulley
To remove the squirrel cage fan, you’ll first need to unscrew the two bolts holding the motor to the blower pulley. Once unbolted, you can simply lift the motor pulley off the shaft. Once you’ve removed the fan, you’ll need to replace the blower pulley. Then, you’ll need to replace the belt.
To begin, disconnect the hot and neutral wires from the motor. You can also disconnect the ground wire from the motor’s base. Make sure the motor is not damaged. If it’s not, you’ll need to replace the blower pulley. This will give you access to the fan’s motor. Once the fan is unplugged, you’ll want to replace the motor pulley.
Checking the motor voltage
If you suspect your swamp cooler has a problem, check the motor voltage. The motor’s voltage capacity is usually printed on the side of the cooler. Applying too much voltage to the motor could cause it to overheat, causing damage to its circuitry and wiring. The best way to prevent this is to apply the correct motor voltage. The voltage capacity listed on the motor is not its maximum operating voltage. Rather, the motor should run at 55 to 60 percent of its total capacity.
If the thermostat is set too high, the fan will not blow cold air. Check the motor voltage and reset the thermostat. If the fan still does not blow cold air, then the motor may be too hot or the thermostat is set too high. You may also need to adjust the thermostat. If it is set too high, the swamp cooler might not be blowing cold air, causing the motor to stop running altogether.
Winterizing a swamp cooler
If you’ve been wondering how to remove the squirrel cage fan from a swamp cooler, you’ve come to the right place. This evaporative cooling system works by pulling air through a mesh, allowing it to cool as it passes through the water. The fan forces this cooled air through walls and into ductwork that distributes it throughout the area being cooled. Most swamp coolers can cool a room or an entire home by 20 degrees or more.
First, remove the back cover. The back cover may be pushed up or squeezing the center of the grille to release the back cover. The back cover is attached to the motor by two screws. If it does not slide, turn it upside down and unscrew the screws. Once the back cover is off, remove the motor shaft. You can also adjust the voltage of the motor pulley with an Allen wrench.
