Hi there. The AC in our bedroom was making a lot of noise a few weeks ago. I thought of inspecting it to figure out why is my air conditioner making crackling noises. I was able to find the problem. However, I called an AC technician to fix the issue, who later shared some more reasons for the crackling noise. Dust particles get stuck in the condenser, which is one of the causes. I will tell you more about this below.
Why is My Window AC Making a Crackling Noise?
Here are a few reasons why your AC is making a crackling noise:
Breakdown of the fan motor bearings
Screws have loosened up
Dust particles trapped in the condenser
Breakdown of the fan motor bearings
If the noise is screeching when you turn on the AC, the reason could be the lack of lubrication in the motor fan bearings. If you can reach the bearings, lubricate them with oil or any other appropriate lubricant. Clean the dust or debris as well.
Screws have loosened up
Another cause could be the loose screws in the AC. You can fix this simply with the help of a screwdriver to tighten the screws. I would advise not to experiment with the outdoor unit while finding the screws if they are not visible at a glance.
Dust particles trapped in the condenser
If there is aggressive banging in your AC, dust particles or little leaves might be the reason behind it. Open the condenser cover from the condenser unit, which is present behind the thin metal find of the outdoor unit. Get rid of dust and stuck material gently using a soft brush and place the cover back.
So, this is all I have to share. I hope it helps.
