Where is the Pilot Light on a Camper Furnace?
What is the Pilot Light?
The pilot light, also known as the igniter or pilot, is a crucial component of your camper’s furnace system. It’s a small, continuous flame that helps light the burner when the furnace is turned on. The pilot light serves as an igniter to ignite the fuel (LP gas or propane) to produce heat in your camper.
What is its Purpose?
The primary function of the pilot light is to provide a flame that helps:
• Light the main burner when the furnace is turned on
• Provide a consistent supply of gas to the furnace
• Burn off excess gas during defrost mode (for water-cooled furnaces)
• Self-test and automatically relight the main burner if it goes out
What Happens If the Pilot Light Goes Out?
If the pilot light extinguishes, you may not have heat, and it can also trigger an error code or alarm on your camper’s electrical system. You may see a light indicator or warning message, and the furnace may shut off to prevent damage.
Where to Find the Pilot Light?
So, where exactly is the pilot light located on your camper furnace?
Step 1: Locate the Furnace and Access Panel
- Typically, the pilot light is located at the bottom or back of the furnace unit. You’ll usually find the furnace behind an access panel or beneath the camper’s flooring.
- Remove any screws or latches holding the panel or flooring to access the area.
Step 2: Identify the Pilot Light Assembly
- Inside the furnace compartment, you’ll typically find the pilot light assembly. It’s usually attached to the side of the furnace unit or at the bottom near the burners.
- Identify the pilot light pilot tube (typically marked with an arrow pointing down) attached to the top of the pilot light assembly.
Step 3: Examine the Pilot Light Element
- The pilot light element is usually located at the end of the pilot tube. It consists of:
- A small orifice or tip
- A jet or injector
- A heat shield
- An igniter button or electrode
- Examine the area to confirm the location of these components.

Tips and Best Practices
When working with propane appliances like your camper’s furnace, always remember to:
• Follow manufacturer’s instructions for maintenance and repairs
• Use safety gloves and a propane-resistant spark source to avoid ignition mishaps
• Store matches, lighters, or other potential ignition sources out of reach
• Disconnect the gas supply when servicing the pilot light to avoid accidents
• Be mindful of sparks and static electricity when handling electrical components
