How to Replace a Squirrel Case Fan in a Air Condition Unit
If you’ve ever had an air conditioning unit repaired by a technician, you’ve probably heard about the squirrel cage and its role in the operation of your unit. Essentially, the squirrel cage is a type of energy source and is used to blow air from your unit. Here’s how to replace one without hiring an HVAC technician. Read on to learn more. Listed below are some steps to follow in order to properly replace this fan.
Condenser fan motor
If the fan has stopped rotating, you may need to replace the motor. The condenser fan uses a different type of motor. The output bearing is prone to failure, while the blower motor’s blade resembles a hamster wheel. If the motor shaft bolt is loose, it will cause the blade to rub against the fan housing. A broken motor shaft bolt may also cause a grinding noise.
To replace this part, check the capacity of your AC system. This motor provides the power to move the air in the home. The blower motor must match the capacity of the overall AC system. The bigger the blower motor, the more expensive the unit will be. To ensure that the fan motor is not faulty, inspect the entire condenser unit for leaks. Once you’ve cleaned all the parts, you’re ready to replace the motor.
Squirrel cage blower
When you notice unusual sounds coming from your HVAC system, you might need to replace the squirrel cage blower motor. A broken belt or bearing could mean that the motor needs to be replaced. A damaged motor part will also need to be replaced. These parts consume the most amount of power, so replacing them is vital. To remove a squirrel cage blower motor, follow these steps. You will need a nut driver to remove the mounting brackets. Once you’ve removed the mounting brackets, pull out the motor assembly. Be careful as the motor is attached to a capacitor, so it can easily be damaged.
The squirrel cage blower is an important component of an air conditioning unit. It moves air throughout the system and is sized to handle the load. Blower motors can range in horsepower from fractional to several hundred. The blower system should be inspected regularly for proper air conditioning and heating maintenance, including changing the belt and bearings. If the blower is causing the air to stagnate in a room, you may need to replace the squirrel cage blower.
Condenser fan blades
A fan blade in an air conditioning unit is a critical component of the cooling system. This blade fits onto the motor shaft and blows air over the condenser, which cools the refrigerant. The blade rotates on the motor shaft to move air and cool the room. Typical fan blades are made of white plastic and come with a slinger ring for proper installation.
First, remove the broken fan from the condenser. You must be careful when lifting the coil and refrigerant lines to avoid damage to the fan motor. Install the new fan and tighten the screws with a spring clamp. Be sure to use perpendicular jaws in a vice grip to keep the spring clamp in place. If the fan is attached to a cage, you may need to unbolt the fan cage to remove it.
Repairing a squeaky blower fan
If you notice a squeaky fan in your air conditioning unit, you can usually diagnose the cause of the noise by disassembling the blower assembly and inspecting its parts. Often, a loose or damaged fan blade clamp will cause the fan to vibrate or wobble. If you see a squeaky fan coming from your air conditioning unit, you may need to replace it.
Another common problem is a worn out blower belt. If you can’t find the problem on your own, you can always get a replacement belt. Motor shaft bearings are another common cause for this problem, and these can be easily fixed with regular maintenance. Oil all moving parts, including the blower belt, to prevent future problems. If you can’t locate the problem in the blower, it may be a faulty motor.
Cleaning a condenser fan blade
To clean a squirrel cage fan blade in an air conditioner, you will need to remove the front control panel and unscrew the two screws holding the blower assembly in place. Then, use a vacuum cleaner to clean the blades. Make sure to avoid disturbing the counterweights that are mounted on the blades. Once cleaned, reinstall the fan assembly. After you’ve cleaned the blades, replace the filter and reassemble the unit.
It is important to clean fan blades in an air conditioning unit regularly to prevent a buildup of dust and dirt. The fan blades are responsible for transferring excess water from the drain to the condenser coils. When the blades become caked with dirt and dust, they restrict airflow and increase the operating temperature. High operating temperatures are harder on electrical components. Moreover, caked-on fan blades reduce the air output of the air conditioner.
