Thermostat: The thermostat regulates the furnace’s operation, turning it on and off based on the desired temperature settings. In gas and oil furnaces, the combustion process generates heat, which is then transferred to the indoor air through the heat exchanger. Electric furnaces use elect...
If you don't know how to use a Honeywell thermostat, you might have trouble staying comfortable because it's the climate-control center for your house. Depending on the nature of your home'sHVAC systemand your heating and cooling needs, you could have — in order of increasing complexity ...
Now that you’ve learned how to replace a thermostat withoutprofessional thermostat installation, you can decide which new type of thermostat to install. Although installing a programmable thermostat or smart thermostat makes the most economical sense, you can also use the steps above to install manu...
The two transformers provide the power the thermostat uses to switch on the various relays. The relays in turn switch on the power to the fan and the air conditioner or furnace. Let's see how this power flows through the thermostat when the air conditioner is running. Power from the air-...

How do you test a thermostat with a multimeter? Set the multimeter to the ohms (Ω) setting. Remove the thermostat from its base and disconnect the wires (first take a photo of where they are attached so you know where to replace them). Touch the multimeter probes to the wire terminals...
Burning gas in afurnacealways introduces the potential for overheating, so to prevent a catastrophe, every furnace has a high limit switch that shuts off the gas if the temperature inside the plenum, which is just above the heat exchanger, exceeds a preset value. In addition, most furnaces al...
Step 3:To discharge the capacitor, use a 20,000-ohm, 2-watt resistor -- an inexpensive wire unit available at most electrical supply stores. Fasten the probes of the resistor to the terminals of the capacitor; this discharges the capacitor. If the capacitor has three terminal posts, connect...
