Common Issues & Solutions
Damper position feedback misalignment
Symptoms:
Airflow inconsistency, hunting control behavior, inaccurate BAS position reporting
Solution:
Recalibrate damper position feedback, verify mechanical linkage connections, check for obstruction in damper movement path, reset controller calibration parameters, replace position sensor if damaged or consistently inaccurate.
Fan failure in series or parallel terminals
Symptoms:
Reduced or no secondary airflow, vibration, unusual noise, motor overheating
Solution:
Inspect motor wiring and connections, test capacitor in PSC motors, verify proper voltage to motor, check for mechanical binding in fan wheel, clean accumulated dust from fan assembly, replace motor if testing confirms electrical failure.
Control sequence programming errors
Symptoms:
Improper heating/cooling response, unexpected operation, discomfort complaints
Solution:
Verify controller programming against specifications, check for errors in temperature setpoints and deadbands, review sequence of operation for correctness, update firmware if needed, reprogram controller with correct parameters and sequences.
