No. http://wiki.answers.com/Q/FAQ/3330heblend door only controls the temperature of the air. the airflow depends on the blower motor. So if there is no airflow then you need to find out why your blower motor isn't working.
The filter in the furnace should be placed with the airflow arrow pointing towards the direction of the airflow, typically facing towards the blower motor.
If your car blower sounds like it's working but the airflow feels weak through the vents, it could be due to a clogged cabin air filter, which restricts airflow. Another possibility is a blockage in the ductwork or vents themselves, preventing air from reaching the cabin effectively. Additionally, a failing blower motor or worn-out fan blades can also cause insufficient airflow despite the blower operating. Checking these components can help identify and resolve the issue.
Common signs of a bad blower motor in a vehicle include weak airflow from the vents, unusual noises such as squealing or grinding, and the blower motor not working at all.
The blower unit on a High-speed Ribbon Blower typically gets its power from an electric motor. The electric motor drives the impeller inside the blower unit, creating airflow and generating the necessary suction or pressure for the blower to operate efficiently.
you have to remove the frot cover,and so you can see the two units
As long as everything is working correctly and clean from the blower motor, the blower wheel, the blower housing is clean, the resistor and switch are working and the cabin air filter is clean if your vehicle has one then you cannot increase the flow.............
The furnace filter goes into the furnace with the airflow arrow pointing towards the blower motor.
Symptoms of a bad blower motor in a vehicle include weak or no airflow from the vents, strange noises coming from the dashboard, and the air conditioning or heating system not working properly.
To read the CFM (cubic feet per minute) on an air handler blower, you typically need to refer to the manufacturer's specifications or the blower's rating label, which indicates its airflow capacity. CFM can also be measured using an anemometer or airflow meter placed at the supply vent to gauge the actual airflow. Additionally, you can calculate CFM using the formula: CFM = (Air Velocity in feet per minute) x (Area of the duct opening in square feet). Always ensure the system is set to the desired speed for accurate readings.
Common signs of a malfunctioning AC blower fan motor include reduced airflow, strange noises coming from the unit, inconsistent cooling, and a burning smell.
The blower in a fan is responsible for generating airflow by pulling or pushing air through the fan. It helps to circulate air in a room, cool equipment, or exhaust stale air. The blower creates the pressure difference needed to move air efficiently.
