How To Light A Propane Furnace? Top Troubleshooting Tips

Familiarizing Yourself with Your Propane Furnace


To familiarize yourself with your propane furnace and solve lighting issues, take a look at the parts of a propane furnace. From there, learn about the reasons why pilot lights go out, as well as some common pilot light issues. Before attempting to light your propane furnace, be sure to observe the necessary safety precautions to avoid potential hazards.

Understanding the Parts of a Propane Furnace

A propane furnace is a must-have for home heating. It turns propane gas into heat to warm your house. 

Let’s take a closer look at the parts.

  • Thermostat: senses the desired temperature and tells the furnace to turn on or off.
  • Burner: burns the propane and produces heat.
  • Pilot Light: a small flame that lights up the burner when needed.
  • Heat Exchanger: transfers heat from the combustion process to the air circulating in ductwork.

Plus, most furnaces come with an air filter, a blower motor, and an exhaust vent. The air filter cleans the air before it enters the ductwork. The blower motor pushes the warm air through the ducts and distributes it in your home. The exhaust vent removes gases like carbon monoxide from the combustion process.

Surprisingly, propane has been used as fuel since 1910. Back then, it was extracted from oil or gas byproducts. But technology has improved and now it’s cleaner and more efficient to get and use this resource. Now, millions of homes rely on their propane furnace to stay warm during cold days.

Know what your propane furnace is capable of. With regular maintenance, like changing your air filter and scheduling service visits, you’ll keep it running smoothly. With knowledge of your furnace, you can keep your home safe and warm for years.
