Why would my window AC just stopped working?

Just to be clear, why did my AC stop working in my window?

Air flow is the most common reason why window conditioners stop blowing cold air. The most common reason window air conditioners stop blowing cold air is a lack of airflow. If the filter is dirty or blocked, it may result in a reduced air flow to the evaporator coils. This can cause them to get too cold, causing frost and ice on them.

The second reason why my air conditioner's reset button keeps popping out is that it doesn't work when I plug in the unit. Overheating, electrical overload, cord pinching, or aging may cause the power supply cord to trip. After resolving the issue, press and release. RESET (listen to the click; the Reset button will activate and, on some devices, a green signal will turn on) will allow you to restart operation.

It is also important to understand what could cause an AC unit not to turn on.

If the AC unit isn't turning on, it's usually because the circuit breaker was tripped. The thermostat is likely to be the next reason if the AC unit doesn't turn on. The thermostat that is not responsive will cause the system to stop communicating with the central air system.

How can you troubleshoot an air conditioner in a window?

Your air conditioner may not provide cool air due to a dirty filter or a damaged coil. Clean the air filter to fix it. If this doesn't work, clean the condenser coil located on the exterior of the unit. It may be necessary to replace it if damaged.
