We recently performed a no cooling call visit for a commercial property in Salisbury, MD. This space is near US 13 North by Delmar, used by a national retail chain and classified as light commercial. There are several reasons why an AC can be running but not cooling. These include but are not limited to: a clogged air filter, faulty compressor or refrigerant issues.
In this particular case, the tenant was complaining of a thermostat setpoint not being met. Upon arrival, the Trane, 10-ton, YSC series, rooftop gas system was in lockout. We tested the control board per manufacturer's specifications to determine what mode lockout occurred in and discovered the system in a cooling mode lockout. It was verified that no major or obvious issues were present resulting in the power to be cycle in order to reset the system.
Upon startup, the condenser fan motor was extremely noisy and through further inspection, motor was drawing double the rated amperage. In conclusion, the unit was likely going off on high head pressure after running and fan going off on overload, leading to us quoting a condenser fan replacement.
Is a condenser fan necessary?
The condenser fan plays a pivotal role in your air conditioning setup. Its main function is to lower the temperature of the refrigerant gas, transforming it into a liquid state. This vital function facilitates the effective extraction of heat from your indoor environment, which is essential for proper air conditioning. A few signs that your AC fan motor is bad, include: fan doesn't stop, fan doesn't start, airflow isn't cold or the AC runs intermittently. Looking for AC repair near you? Contact Us Today
