Identifying the Types of Noises. Pinpointing the specific type of noise your AC compressor makes when the clutch engages is crucial to diagnosing the issue: Squealing: This high-pitched noise often suggests a belt issue. The belt may be old and stretched, causing it to slip on the pulleys. It can also indicate misalignment or a lack of tension.Air compressors made by the Wayne Company have been around for years, and they are still a favorite of the various industries, like car maintenance, that make extensive use of air ...The following interlocks must be meet for the A/C compressor to transition states from off ...
