Gas Furnace Won't Turn On | Basic Troubleshooting Trane Gas Furnace with No Heat

On Christmas Eve, the gas furnace would not turn on. The Trane gas furnace gave no heat and the temperatures were in the single digits Fahrenheit! The so I checked the typical suspects. Furnace air filter, ignitor, and flame sensor. As in our example, it is always a good idea to have these spare parts on hand especially for holiday breakdowns. Check Amazon for:

✅ EASY TO INSTALL: SEN01114 Furnace Flame Sensor is a direct replacement for many American Standard residential furnace models.
✅ PRODUCT SPECIFICATIONS: If SEN01114 Furnace Flame Sensor is defective, the furnace may not heat properly. This flame sensor monitors the burner to detect whether or not a flame is present. When the sensor does not detect the flame gas valve is closed to prevent gas leaking into the home.

Our BASIC TROUBLESHOOTING involved
1) Checking the air filter to make sure it was not clogged. A dirty air filter or a clogged air filter can stop the furnace from functioning properly.
2) Check to make sure the igniter glows - the ignitor must glow to ignite the gas.
3) Check the flame sensor and clean if it has heavy carbon deposits which can sometimes interfere with proper functioning. But, even a clean ignitor can be broken or defective so looks don't always tell the story.

Ultimately, our issue was traced back to a faulty connection between the Nest Thermostat and the control board. But most often, a gas furnace which is not turning on can be traced to simple causes like a bad ignitor or a bad flame sensor.
