FAQ
...
Failure to Start
- Causes: Power outage, phase loss, capacitor failure, overload protection trip, motor burnout - Solutions: Check power supply/wiring, replace capacitor, reset overload protector, repair motor
Low Airflow
- Causes: Dust accumulation on impeller, clogged filter screen, reverse rotation, loose belt - Solutions: Clean dust/wash impeller, check wiring phase sequence, tighten/replace belt
Excessive Noise & Vibration
- Causes: Impeller imbalance, bearing failure, loose fasteners, resonance - Solutions: Tighten fasteners, replace bearings, perform dynamic balancing, install vibration dampeners
Motor Overheating
- Causes: Overload, unstable voltage, insufficient bearing lubrication, poor heat dissipation - Solutions: Reduce load, check voltage, lubricate/replace bearings, improve ventilation
Abnormal Sounds / Friction Noises
- Causes: Impeller rubbing against casing, bearing damage, foreign objects present - Solutions: Adjust clearances, remove foreign objects, replace bearings
Circuit Tripping
- Causes: Short circuit, ground fault, motor burnout, overload - Solutions: Check wiring insulation, replace motor, resolve motor stalling issues
Failure to Open / Close Tightly
- Causes: Actuator failure, seized shaft, loose linkage rod - Solutions: Replace actuator, lubricate shaft core, tighten linkage rod
Excessive Air Leakage
- Causes: Aged sealing strips, deformed blades, excessive gaps - Solutions: Replace sealing strips, straighten blades, seal gaps
Unresponsive Adjustment
-Causes: Actuator angle misalignment, signal/wiring fault -Solutions: Recalibrate, inspect wiring and controller
Abnormal Noise / Vibration
-Causes: Loose blades, airflow resonance, unstable mounting -Solutions: Tighten screws, reinforce brackets, reduce airflow speed
