There are various parts that can break, some are easy to notice, and others are more difficult. A few signs will quickly make you realize that something is wrong with your AC.
According to Lee Heating and Cooling, one of the easiest ways to notice something wrong with the AC is the foul smell. An awful odor can be caused by various reasons and, in some situations, can be fixed by the owners, but in some others cases, professional repair is necessary.

Professionals must check the AC unit, the broken parts need to be replaced, and most importantly, the wires need to be checked. Wiring is essential because they are the reason for the burning smell. They need to be correctly connected and isolated. You can check the socket as well, to see if something is wrong with it that affected the electrical power sent to the AC and produced the burnt smell.
In some situations, this smell can come from burnt dust. This typically happens when the unit has not been turned on for a long period of time, so dust settles in the unit. The easy fix is to clean it properly and blow away the dust. You should keep in mind that when doing any maintenance or repair to the appliance, it should be unplugged from the electrical source.

The Smell of Sewage
The smell of sewage is an awful experience, but unfortunately is one of the most common reasons why ACs produce offensive odors. The good part is that this issue usually has an easy fix and often doesn’t require the intervention of technicians. This smell is most likely coming from clogged pipes or water in the system that became stale. Draining the water should be enough to fix the issue of this type of bad smell. To unclog the pipes, certain chemical products will do the trick. If they remain clogged, professionals might be needed to fix the problem.
