RTU not cooling
Symptoms:
Warm air discharge, high discharge temperature, insufficient cooling capacity
Solution:
Check refrigerant charge, inspect evaporator coil for dirt/frost, verify compressor operation, test expansion valve, ensure proper airflow across coils.
Economizer failure
Symptoms:
No fresh air intake, stuck damper position, high energy consumption
Solution:
Inspect damper operation, check actuator function, verify sensor readings, clean economizer components, replace if mechanical failure is confirmed.
Compressor short cycling
Symptoms:
Frequent on/off operation, poor temperature control, high energy usage
Solution:
Check refrigerant charge, verify pressure controls, inspect temperature sensors, ensure proper airflow, test compressor windings and capacitors.
