The fan switch provides the necessary 120 volts to the fan motor for it to operate. We took this image on the net we consider would be probably the most representative images for basic furnace wiring diagram with transformer. In the future I'm sure we will start to see a required neutral which has already begun with electric ranges and clothes dryers. The gas solenoid opens to let in the gas, and the pilot light ignites it. . Therefore, we will use it here to look at a typical heating system.
I was online most of the time to see the different possibilities and ideas that I can get from these useful articles. I don't want to make a boo boo now. What to Do with a Spare Wire So just cap the neutral off because its a spare wire, better to have too many than not enough!

An example of this would be a relay that has its solenoid coil energized by 24 volts, but the contacts of the relay control a voltage of 120 volts. The position diagram is not included in all manufacturer diagrams. A new system may need as many as ten wires like a two-stage heat, two-stage cooling system, heat pump reversing valves, fan control, etc. Furnace Blower Wiring Diagram Service This unique furnace blower wiring diagram that offers along 14 pictures along with old furnace wiring diagram also with electric furnace wiring diagrams along with ac furnace wiring diagram together with furnace blower fan relay wiring furthermore furnace blower relay wiring diagram as well as goodman gas furnace wiring diagram furthermore basic gas furnace wiring diagram including nordyne furnace blower wiring diagram moreover hvac fan motor wiring diagram also with 3 wire furnace blower wiring diagram additionally furnace blower motor schematic together with old oil furnace wiring diagram along with mobile home furnace wiring diagram together with nordyne furnace wiring diagram together with dayton furnace blower wiring diagram including york furnace wiring diagram together with hvac thermostat wiring diagram also with furnace blower motor wiring furthermore furnace fan relay wiring diagram together with furnace fan wiring diagram.
When the plenum on top of the furnace reaches 90 degrees F, the blower switch opens and turns off the blower. We all know every persons opinion; will be different from each other. It sounds like you have been busy wiring your home, good for you! The videos below are a training tool to help understand how to read the schematic diagram. The wiring diagram shows where the wires are mounted to the components and usually including wire color codes and sometimes numbers for wire identification. Wiring color code or symbols, wiring harness, radio and audio wiring, circuit diagram, light switch wiring diagram. Electricity can be downright scary.
We also have collections such as wiring diagrams, fuse boxes, engine diagrams, circuit diagrams, engine problems, engine schematics, parts diagrams, replacement parts, electrical diagrams, repair manuals, transmission diagrams etc. They connect to a two-wire thermostat generally a mechanical thermostat with a mercury filled ball connected to a coiled bi-metal strip. The obvious down side of this is that if the battery goes dead the thermostat will no longer function. You have given me confidence to do my own projects which I never had before. Make sure your ground wire is attached to the provided ground lug or terminal, and back at the panel bond the ground as well. When the air in the plenum reaches 120 degrees F, the fan switch closes and the fan starts.
If the fan fails to run for any reason, the heat exchanger will get too hot and the hi-limit temperature device will open the circuit to the gas valve, closing the valve and stopping the heat cycle. However, the terminals of the thermostats of today are still labeled the same, and provide the same functions as what we have discussed thus far. Thanks Ray Hi Ray, I understand your question, a lot of people get confused with 220 Volt circuits and just what to do with the extra white wire.

L1 and L2 Wiring As you mentioned, the L1 and L2 are the 2 hot lines coming in and it does not matter which one goes where. Note the location of the blower switch and the limit switch. In order to identify a component split up this way, both parts of the component will be labeled in the diagram with the same designation.
The transformer provides low voltage for control of the gas solenoid. The gas furnace is the simplest to operate and understand. For more information, see this resource link that I found:.

A basic two-wire thermostat can be compared to a simple single-pole switch that you will find throughout your home, only instead of you turning the switch on and off as required, a mechanical or electronic temperature controlled mechanism is the operator of the switch. The wiring diagram shows L1 and L2 for the hot sides red and black and the ground is separate.

If there is no termination for a neutral and the instructions do not call for a 3-wire circuit with a ground then a neutral is not needed. Some info I have found shows that a furnace can be run with only two hot lines and a ground line. Now that you are armed with a basic understanding of the temperature control system in your home, you should now be able to identify what kind of system you have, and what type of functions you will need if replacing or up-grading your existing thermostat. Figure below shows a simple circuit needed to control a furnace with a blower.
