Your Air Conditioner is Icing Over
What Causes Icing
Icing over occurs when the evaporator coil of your air conditioner freezes due to excessively low temperatures, resulting in the freezing of moisture present in the air. This ice accumulation has the potential to render your air conditioner completely inoperable, in addition to producing popping or crackling noises.
Follow these steps to repair a frozen air conditioner:

Step 2: Examine the coils for obstructions and soiled areas after the melting of the ice.
Step 3: Remove any loose dirt and detritus from the coils using a soft cloth or brush in the third step. To clean the coils, combine warm water and dish soap in a spray bottle.
Step 4: Due to insufficient refrigerant levels, your air conditioner may ice over in certain circumstances. You will need a professional to resolve the matter if you suspect that is the issue.

Step 2: Inspect the interior of the air conditioner with care. Verify that there are no loose components and secure them as necessary. Ensure that you do not overtighten, as doing so could result in further complications.
Problems with Wiring
A wiring malfunction is a potential cause for crackling or popping noises emanating from the electrical components of your air conditioner. Arcing or sparking noises can be produced by frayed or damaged wires; if not repaired, these sounds can be hazardous.
Consider the following course of action.
Step 1: Unplug and turn off the air conditioner.
Step 2: Proceed with the interior access of the unit according to the type and manufacturer’s guidelines.
Step 3: Thoroughly examine the circuitry to identify any frayed or impaired wires. As necessary, replace and tighten them. It is advisable to contact a professional if you lack the necessary expertise to handle electrical components.
Something Stuck in a Vent
A crackling sound may indicate that an object has become lodged between one of the air conditioner’s louvers or openings. The fan’s apertures could cause even a rigid object such as cardboard or paper to generate a clicking or crackling sound.
