Step-by-Step Action Plan

Follow these steps before calling a technician — you may be able to resolve the issue yourself.

1

Check Power Supply

Ensure that the circuit breaker is not tripped and that the fan is plugged in properly. If it’s hardwired, check the wiring connections.

2

Inspect Ducting

Look for any blockages in the ductwork that may prevent airflow. Ensure that the duct is correctly installed and not crushed.

3

Listen for Noises

Turn on the fan and listen for any unusual sounds. If you hear rattling or grinding, the fan may need maintenance.

4

Test the Light Functionality

If your fan has a light, check if it works. Replace the bulb if it’s burnt out and check the switch for issues.

5

Check Installation Angle

Ensure that the fan is installed at the correct angle to maximize airflow. Adjust if necessary.

6

Evaluate Electrical Components

Inspect all electrical connections and components for wear. If you suspect an electrical fault, consult a professional.

Always turn off power to the unit at the breaker before inspecting any components. Safety first — even for simple checks.
