Dismantling An Aircon Unit Blower During Cleaning

What is an Aircon Unit Blower? 

Also known as the aircon unit fan, the blower serves as one of the key components of a fully functioning aircon unit. An aircon unit uses blowers to transfer the warm air away from any space and replace it with cold air. It also maximizes airflow for better circulation and machine function

How does an Aircon Unit Blower work?

The aircon unit blower motor is the heating and cooling systems component that sends conditioned air from the furnace, heat pump, or air conditioner into the home. Once the system heats or cools the air, the blower motor forces it through the duct system and out the vents in rooms throughout the house.

How do you know if your Aircon Unit Blower Motor is bad?

Be aware of the following signs and symptoms of a bad Aircon Unit Blower Motor:

Aircon unit fan doesn’t start even though you have the aircon unit turned on

– Aircon unit fan doesn’t stop 

– Slow rotating blades or outside fan blades are still 

Rattling, humming, and buzzing noises

– Aircon unit runs intermittently

No cold airflow

Steps in safely Dismantling an Aircon Unit Blower during cleaning or servicing:

Step 1) Carefully remove the front cover

Most aircon units possess a smooth white front cover to protect their inner components. This cover is composed of plastic, and it needs removal to access the indoor parts. There are several screws located at the bottom of the unit. Once you remove these, popping off the front cover is easy, and it can be set aside.

Do not worry about screws at the top of the case, as usually there are none. Aircon manufacturers understand that most air conditioning units will be installed by a professional aircon servicing company high up on the walls. It would not be feasible to place screws at the top because of this design facet.

Nevertheless, if the case is not coming off easily, you should not force it. Other screws or clamps should be located, and see if anything else is holding it in place.

Step 2) Set aside the Drain Panel

Once the front cover has been removed, you can now access the inside components of the aircon unit. When you perform the service yourself, you may notice that the blower wheel is surrounded by other parts. To have more room to work with the aircon unit blower, the surrounding parts must first be set aside.

The drain panel is a large panel found in front of the aircon unit blower. Professionals do not secure or attach most drain panels using any sort of screws or bolts. They are just fixed in place by tabs and clamps in the corners and middle of the panel.

The drain panel is rather large and difficult to remove completely. A professional aircon servicing company recommends just setting it aside and letting it hang while you service the aircon blower.

Taking it out of place is simple, but removing it from the aircon is a complex task.

Step 3) Remove screws of the Blower Wheel

This step is a tricky one because the screws are not immediately visible and accessible. Finding the blower wheel right behind the drain panel makes it concealed already. The screw for the blower wheel attaches it to the blower motor that making it function.

To find the screw, search at the inside of the blower wheel on the right. This location means that you have to spin the blower wheel until you can see the screw.

Furthermore, you need to insert the screwdriver into the wheel to remove it. It is always important to be careful and make sure not to mess anything up when poking the screwdriver inside.

Step 4) Move the Evaporator Coil with care

The last part blocking access to the aircon unit blower is the evaporator coil. It is the large metal sheet that you see in the front. It is responsible for absorbing the heat in the room so it is important to be careful with it.

There are screws located on the side of it. Removing the evaporator coil completely is not required, nor is it advisable.

Just remove enough screws to loosen it so that you can effortlessly move it. Once you have done this, you should be able to move it enough to reach in and grab the aircon blower to remove it.

Step 5) Pulling out the Aircon Unit Blower

You can now move the evaporator coil enough to grab the aircon unit blower. Grab it and pull it out gently. It should come out with no resistance if you had removed the screw properly in the previous step. Now that it is out, it can be properly cleaned or serviced.

To return everything in place, perform everything previously done in reverse.
