Which symptom is most directly associated with a burned-out compressor?

• A. A pungent smell
• B. Excessive cooling
• C. No movement of refrigerant
• D. Loud fan noise

Answer: (A)

A burnt-out compressor often gives a strong burnt odor as the motor windings and lubrication overheat and insulation can burn. That smell is a direct signal that internal components are overheating or damaged, which is why it’s the most telling clue of a compressor burn-out. Other signs like excessive cooling, no movement of refrigerant, or loud fan noise point to other issues: excessive cooling usually stems from charging or metering problems, a seized compressor would stop refrigerant flow, and loud fan noise typically comes from the condenser fan rather than the compressor itself. So the pungent burnt odor is the clearest, most direct symptom of a burned-out compressor.
