Replacing the compressor involves assessing its functionality, and one key indicator is whether the electromagnet clutch is receiving voltage. If there is no voltage present at the electromagnet clutch, it indicates that the clutch is not engaging. This lack of engagement could prevent the compressor from functioning properly, potentially leading to the conclusion that the compressor must be replaced if other tests do not indicate a problem with the system itself.

Voltage to the electromagnet clutch is critical for it to engage the compressor, allowing it to circulate refrigerant throughout the system. Without voltage, an otherwise functional compressor cannot operate, thus signaling a need for replacement either because of an electrical issue or possibly a fault within the compressor itself.

In contrast, the situation where the continuity of the compressor clutch is verified does not directly lead to the conclusion that the compressor should be replaced. Similarly, if the AC system is not producing cold air, it could be due to several issues other than a failed compressor. Lastly, while physical damage to the compressor would certainly warrant replacement, the absence of voltage at the electromagnet clutch effectively points to potential failure at a level that usually necessitates addressing the compressor itself.
