HOW TO replace aircon fan motor

Step-by-Step Guide to Replace Aircon Fan Motors

1. Safety First

When you start working on any electrical appliance, ensure to turn off the power. Find and switch off the circuit breaker that controls the current to your aircon. Verify that there is no current flowing in the aircon. Try to turn the aircon on and it should not. If it does, it indicates the aircon is still in connection with the electrical power. 

2. Access the Fan Motor

Remove the cover of the aircon and bible from the manufacturer’s user manual to remove the screws and lift the cover off. Be cautious not to damage the components in this process. 

3. Locate the Fan Motor

When you remove the cover, find the fan motor, which is usually found near the centre and connected to the fan blades. Thoroughly check the connections and take snaps before you remove the motor. You can use these pictures later on to reassemble the new fan motor. 

4. Disconnect the Fan Motor

Here is the procedure to remove the fan motor from the aircon unit.

  • Disconnect the fan motor from the power source and other connections.
  • Check the residual charge in the circuit using a DMM. If there is a charge, wait for it to disappear. 
  • Disconnect all the wires from the fan motor. 
  • Keep a picture of the connections to know the reconnection in the later part. 

5. Remove the Fan Motor

Now, the fan motor is not connected to any other component of the aircon. The fan motor may have some screws to hold it in place within the aircon. Loosen and remove the screws to slide the motor out. Be careful not to damage other components in this process. 

6. Install the New Fan Motor

Compare your new motor with the old one and check the ratings. Install the new motor in the same slot where the old one was placed. Connect it to the aircon using screws and brackets. Ensure that it is securely attached to the fan blades. Tighten the screws without damaging them. 

7. Reconnect the Wires

Do the connections by looking at the connection snap that you took in step four. Ensure the connections are correct and securely completed. Make sure there are no loosings or false connections. 

8. Test the New Motor

Before you close the casing, inspect the functionality of the new fan motor. Turn on the circuit breaker power and the aircon. Ensure the new fan motor is working well and does not cause any issues. If there is an issue, check the connections and adjust if needed. Turn off the power and continue to the next step.
