Why doesn't the air conditioner work at the hottest time at noon, and the machine outside is still running, so there is no cool air blowing inside?

Compressor overheating causes protection for the following reasons:

1, serious dust accumulation on the heat sink of outdoor unit, resulting in poor heat dissipation.

2. The capacitance of outdoor fan becomes smaller, and the rotation speed of cooling fan is too slow.

3. Excessive snowfall of air conditioner and increased current lead to overheating protection of compressor.
