Does a variable speed blower run all the time?
Does a variable speed blower run all the time?
Variable speed furnaces have an air handler that operates at many different speeds depending on the demand for air at any given time. A variable speed air handler runs almost all the time, albeit typically at a low setting that is much quieter than the higher setting that’s used during heating cycles.
How is the speed of the blower motor controlled?
The electronic module that controls the speed of the blower motor is called a blower motor control module. In some cars, the blower motor has only 4 or 5 fixed speeds. In this case, the speed of the blower motor is controlled by a blower motor resistor.
What causes a blower motor to turn off randomly?
– Home Improvement Stack Exchange What could be causing an A/C blower motor to turn off randomly? The Blower motor on my AC unit turns off at random times while the outside unit continues to run which is causing the coil to freeze up.
What are the symptoms of a failed blower motor resistor?
Blower motor resistor problems. Problems with a blower motor resistor are common in many cars. The most common symptom of a failed blower motor resistor is when the heater fan only runs at high speed and doesn’t work at low speeds.
How can I tell if my blower motor has a problem?
Press and hold the OFF button and within 10 seconds press and release the Window Defogger button five times. The system enters the self-diagnostic mode and at the end of it, if there is a problem, the fault code will be displayed on the display.

What happens when a blower motor relay wears out?
Without it, the AC system will not be able to circulate any heated or cooled air. The blower motor relay controls the current used to power the blower motor, and is subject to the constant on and off switching. Over time, it can eventually wear out.
