Ignition doesn't occur,and the furnace won't go on. Turn the meter to the ohms setting (resistance is measured in ohms). When your thermostat calls for heat, the furnaces circuitry passes a high voltage between the spark plugs center electrode and ground electrode, breaking down the insulation between the electrodes and allowing current to flow in the discharge phenomenon. The first patent on the gas furnace was in 1919, and by the 1940s, gas furnaces started to become popular as central heating options, replacing coal-burning furnaces because of their power, improved safety, and convenienceno more need to take delivery of coal and shovel it into the furnace, the natural gas comes right to the home. Once the burners are on, the gas . With no safe method of proving a flame, it is possible to allow large volumes of gas into the area around the furnace. That causes the overall system to suffer when it comes to efficiency. A pilot light always burns gas, regardless of whether a heating cycle occurs. In some furnaces, the HSI also serves as a flame sensor (called local sensing) instead of having a separatesensing rod in the burner flame (remote sensing). Once you find it, you must place it aside before continuing. I am very appreciative of his responsiveness and CB professionalism. Miguel was on time and courteous!
