What is a sign that a compressor may be overheating?

A compressor that is overheating often shows signs that indicate an issue with its operation. One clear sign is the frequent shutdown of the compressor. This shutdown is typically a protective measure to prevent damage due to excessive heat.

When a compressor overheats, it may reach a temperature that compromises its function, leading to thermal overload. This triggers an internal safety mechanism, causing the unit to shut down and prevent further heat build-up or possible failure. Therefore, a frequent shutdown is a strong indicator that the compressor is experiencing problems related to overheating.

Other factors, such as high suction pressure or increased refrigerant return, can result from various issues and do not specifically indicate overheating. Low ambient temperature, conversely, is not related to overheating as it pertains to external conditions rather than the compressor's internal temperature. Understanding these signs can help in diagnosing compressor issues effectively.
