Let’s talk about DIY air conditioner fan replacement guide
If you suspect that the condenser fan motor is bad, you should check it to be sure before it is replaced. Start your diagnosis by closing the power for the air conditioner.
Common engine problems :
Next, you should check to see if the fan blade turns freely. If it does not, the motor must be replaced. If the blade turns freely, you should feel the engine to see if it is hot.
If the engine is hot, it must be checked that the condenser is running; using our practical guide and replace if necessary. If the running capacitor was bad, the fan motor should be allowed to cool. Then you can activate the unit again and see if the engine starts and that the speed increases. If the fan does not start or does not run at full speed, it must be replaced.
Selection of the motor :
The next step, replacing the air conditioning fan, is to select the right motor. This is also a good time to consider money-saving update for your air conditioner.
All engines have a number/model manufacturers in them. You can find an exact replacement for that number. You can buy your replacement motor through the motor category of the condenser fans on Amazon.
If you can not find an exact replacement, you can usually use a universal substitute. This is what you should look for and combine:
- The diameter of the motor in inches (3.3, 5, 5.5, 6.5)
- the operating voltage (115, 208 to 230, 460)
- Power (1/8, 1/6, 1/4, 1/3, 1/2): Many universal replacement motors have more than one rated power.
- the size of the axis in inches.
- The direction of rotation: Many replacement engines are a universal double rotation. The direction of the rotation is easily changed to meet the required need.
- The mounting method: Many universal replacement motors can be assembled in multiple ways.
Replacing the air conditioner fan :
To begin replacing the air conditioner fan, make sure that the power of the unit is off. Then, you should write down the colors of the fan motor cables and where it is connected.
Then, the motor and fan assembly can be removed. There are several different ways that can be mounted. In general, what is required is to loosen the bolt on the belt that holds the engine in place. In some units, the motor supports are integrated into the motor.
Now, you can remove the fan blade from the motor. It is important that you note the orientation of the blade on the motor shaft. To remove the fan blades, loosen the set screws and turn and pull the blade off the shaft.
The replacement motor is installed simply by reversing the disassembly procedure. Special care must be taken to ensure that the fan blades are centered in the opening of the unit.
In addition, the running capacitor must be replaced at any time a motor is replaced. Make sure you have the right size for your engine and the desired power (for engines with several horsepowers).
Once the engine is installed, you must complete your air conditioner fan replacement by verifying the proper rotation and ventilation operating system.
