Why do I need a variable speed blower motor?
Why do I need a variable speed blower motor?
A variable-speed motor, on the other hand, can operate at lower or higher speeds, which results in a more even temperature throughout your home and better energy efficiency. Similar to other components in an HVAC system, the blower motor will become more vulnerable to mechanical failures as it experiences more wear and tear over time.
When do you need to replace a blower motor?
If you don’t feel any airflow coming out of the vents, it may mean that a problem with the blower motor has developed to the point where the component is entirely inoperable. In this case, you’ll have to replace it with a new motor.
How does the resistor on a blower motor work?
If you start at the blower motor, and check resistance in the circuit, you will find the problem in no time. Power supplied from the fuse panel passes through the switch to the blower resistor assembly. The switch supplies ground to the different resistors in the assembly, depending on the speed selected.
Why does my blower fan only work on one speed?
by Lee Sallings. The most common symptom of a faulty blower motor resistor is a blower fan that only works on one speed, usually high. This can be annoying, but troubleshooting is easy. If you start at the blower motor, and check resistance in the circuit, you will find the problem in no time.

What should air handler blower speed do AC unit need?
It is possible that your AC’s air handler blower is functioning at the improper speed, and to maximize its performance, you should make sure that is not the case. The first step is determining the current speed of your blower so that you can see if it matches the speed recommended for your model.
Can you change the speed of an air blower?
Yes you can but we think its just better to know that it can be done whats involved with a simple speed change of your air blower for your furnace air conditioner or heat pump. Ryan from Environmental Heating & air of nc gives you the color codes and speed of those wires.
What does a blower motor do in an air conditioner?
What Is a Blower Motor? The blower motor is a component in your HVAC system that blows the conditioned air through the vents in your home. It takes the cool air created by your air-conditioner and circulates it throughout your indoor space to ensure that the temperature reaches the level dictated by the thermostat.

Can a blower fan only work on high speed?
Blower Motor Fan Only Works On High Speed? Plus – Tips To Prevent Repeat Failures! If playback doesn’t begin shortly, try restarting your device. Diagnostic training videos and content hosted by ASE Master and L1 Certified Technicians.
Why does my heater not work on high speed?
Heater blower motor will not work on high speed? I have replaced the black bosch relay behind the glovebox, the blower resistor and the blower motor and still cannot get the blower to work on high. I remember in older model years of gmc’s and chevys that their was a high speed blower relay that caused this issue.
How big of a motor do I need to blow air?
The rule of thumb is the blower should produce 440 CFM (cubic feet per minute) of air per ton. On a two-ton system that is 880 cfm (cubic feet per minute). This usually calculates out to about a 1/4 to 1/3 HP blower motor.
