It should not run continuously. Typically, the fan (sometimes called a blower) will continue to run for a minute or so after the flame is out. This does not consume much energy; it does flush the residual heated air from the ducts.
Make sure the fan is set to "AUTO" on the thermostat, to ensure proper cycling.

What does the pilot light assembly look like on a furnace?
The pilot light assembly on a furnace typically consists of a small, tube-like component with a flame holder and a thermocouple. It usually features a small flame that burns continuously, indicating that the furnace is ready to operate. The assembly is often located near the burner and may have a protective cover or shield. In some models, it can be accessed via an inspection door on the furnace’s front.
What does a Flame sensor in a hot surface ignition furnace do?
It tells the furnace that it lit... Hence the name Flame Sensor.
Does a furnace have a pilot light and how does it function in the heating process"?
Yes, some furnaces have a pilot light. The pilot light is a small flame that ignites the main burner when the furnace needs to heat the air. It functions by staying lit continuously to ignite the gas when the thermostat signals the furnace to start heating.
What is the function of a furnace fan limit switch and how does it impact the operation of the furnace?
The function of a furnace fan limit switch is to regulate the temperature inside the furnace. It helps control when the fan turns on and off based on the temperature of the air inside the furnace. If the switch is not working properly, it can cause the fan to run continuously or not turn on at all, which can lead to overheating or inefficient heating in the furnace.
Seguence of operation for a direct ignition gas furnace?

What are the common symptoms and troubleshooting steps for a furnace issue related to a bad flame sensor?
Common symptoms of a furnace issue related to a bad flame sensor include the furnace not staying on, frequent cycling on and off, or the furnace not producing heat. Troubleshooting steps for this issue include cleaning the flame sensor with steel wool, checking the sensor's alignment, and ensuring the sensor is securely connected to the furnace.
Why does the furnace igniter glow but no flame is produced?
The furnace igniter may glow but not produce a flame due to issues such as a clogged burner, a faulty gas valve, or a malfunctioning flame sensor. These problems can prevent the gas from igniting properly, leading to the lack of a flame.
