How do I get my furnace fan to run continuously?

The switch that allows you to do this is commonly known as a summer switch. A summer switch is a small toggle switch attached to the furnace, which, when set to the 'on' position, will allow the furnace fan to run continuously. Another common place to find a summer switch setting is on your thermostat.

Does the furnace fan pull air from outside?

Since high efficiency furnaces draw air directly from outside, the furnace itself does not require a fresh air intake in order to replace inside air that otherwise would have been drawn from the room the furnace is located in. ... No matter what kind of furnace you have installed, the system will push air out of your home.

What is the purpose of the fan switch in a warm air furnace?

The furnace fan limit switch is designed to activate and deactivate the furnace blower assembly. This component is responsible for transmitting warm air throughout the air ducts in your home. In addition, the furnace limit switch is also engineered to shut down the furnace to ensure it doesn't overheat.

What is blower resistor?

The blower motor resistor is responsible for controlling the blower motor speed. ... The change in resistance controls the current through the blower motor, which in turn limits the speed that the blower motor spins at.

Where is the blower motor control module?

It's located inside the dash, often on the opposite side of the steering wheel or inside the engine compartment on the firewall. A blower motor resistor or a blower motor control module is the part that controls the speed of the blower motor.

Can a furnace fan run all the time?

Running your furnace fan all the time isn't exactly a bad thing. In fact, there's no need to worry about the fan wearing out or breaking down because it's designed to run continuously, and there's an array of benefits connected to this.

Where is the furnace fan switch?

Your fan limit switch is located inside the furnace panel cover, usually near the upper right corner. The fan limit switch is responsible for turning the blower on and off at the appropriate times.

Why is my furnace fan not turning on?

Make sure that the power cord hasn't melted or a fuse hasn't been blown. If your cables are looking fine, try unplugging the fan for a few minutes and then plugging it back in again. ... If unplugging and plugging your fan back in again doesn't work, check the fuse box.

Can a blower motor resistor be bypassed?

Blower resistors are made of several resistors with different resistances. ... In the highest speed state, the blower resistor is bypassed completely and the fan is connected directly to the car's battery, which allows maximum current through the motor.
