Service & TroubleshootingCâu 79 / 110
If a condenser fan motor fails while the compressor keeps running, what symptom is most likely?
a.Low head pressure
b.Rising head pressure and possible high-pressure or overload trip
c.Increased subcooling only
d.Lower amp draw on the compressor
Giải thích
Without condenser airflow, heat rejection collapses and head pressure climbs quickly, often tripping a high-pressure switch or the compressor overload. The system may also lose capacity and overheat. Diagnosing a hot, non-spinning fan points to the motor or its capacitor.
