Checking The Thermostat
When your camper furnace stops working, the thermostat is a common culprit. By checking the thermostat, you can often fix the problem quickly. In this section, we will cover some simple steps for troubleshooting.
Thermostat Settings
First, check the thermostat settings. Make sure the thermostat is set to heat and not cool. Verify the temperature setting. It should be higher than the current room temperature.
- Set the thermostat to heat.
- Increase the temperature setting.
- Check if the furnace turns on.
Sometimes the settings get changed by mistake. Adjusting them can solve the issue.
Replacing Batteries
If your thermostat uses batteries, they might be dead. Replacing the batteries can often solve the issue.
- Remove the thermostat cover.
- Take out the old batteries.

Inspecting The Power Source
Understanding how your camper furnace operates starts with inspecting the power source. A reliable power source ensures the furnace functions correctly. It’s essential to check the power supply and the circuit breaker. Faulty power sources are common causes of furnace issues.
Power Supply
First, check the power supply to your camper furnace. Ensure all connections are secure. Loose wires can cause the furnace to malfunction.
Use a multimeter to check voltage levels. The correct voltage is crucial for furnace operation. Verify the power supply meets the manufacturer’s specifications.
Circuit Breaker
Inspect the circuit breaker connected to the furnace. A tripped breaker can cut off power. Reset the breaker if it has tripped.
If the breaker trips again, there may be a short circuit. This issue requires immediate attention. Consult a professional if this happens repeatedly.
Ensure the breaker is not overloaded. An overloaded breaker can cause frequent trips. Distribute the electrical load evenly to prevent this issue.

Examining The Furnace Filter
Keeping your camper furnace in top condition is crucial. One important step is examining the furnace filter. This ensures your furnace runs efficiently and safely.
Filter Condition
First, check the condition of the filter. A dirty filter can block airflow. This makes your furnace work harder. Look for dust, dirt, or debris. If the filter looks clogged, it needs attention. Clean filters improve efficiency and air quality.
Use a flashlight to inspect the filter. Pay attention to the edges and surface. If you see grime or buildup, it’s time to act. A clean filter helps maintain a healthy environment inside your camper.
Replacing The Filter
Replacing the filter is simple. First, turn off the furnace. This ensures safety while you work. Locate the filter compartment. It’s usually near the furnace intake.
- Open the filter compartment.
- Remove the old filter carefully.
- Dispose of the old filter properly.
- Insert the new filter.
- Ensure the new filter fits snugly.
- Close the filter compartment.
Turn the furnace back on. Check if it runs smoothly. A new filter can make a big difference. It helps the furnace perform better and last longer.
Experts recommend changing the filter every three months. This keeps your furnace in top shape. Always have spare filters on hand. Regular maintenance saves time and money.
Investigating The Blower Motor
When your camper furnace isn’t working, start by checking the blower motor. This motor helps circulate warm air. Let’s explore how to ensure your blower motor is functioning correctly.
Motor Functionality
First, check if the motor is turning on. Turn on your furnace and listen for the blower. If you don’t hear it, there could be an issue. Use a multimeter to check for power. Ensure the motor is receiving electricity. If the motor isn’t running, it may need to be replaced.
Lubricating The Motor
Blower motors require lubrication to run smoothly. Locate the lubrication points on the motor. Apply a few drops of oil to each point. Spin the motor by hand to distribute the oil. Regular lubrication keeps the motor running well. It can also extend its lifespan.
Testing The Ignition System
Testing the ignition system in a camper furnace is crucial. It ensures your furnace runs smoothly and efficiently. A faulty ignition system can lead to various problems, including the furnace not starting or the pilot light going out. Here, we will look at the two main types of ignition systems: the pilot light and the electronic ignition.
Pilot Light
The pilot light is a small flame that ignites the furnace burners. To test the pilot light, follow these steps:
- Locate the pilot light assembly.
- Ensure the gas valve is open.
- Check if the pilot light is lit.
If the pilot light is not lit, try to ignite it manually. Follow these steps:
- Turn the gas valve off and wait a few minutes.
- Turn the valve to the pilot position.
- Use a match or lighter to light the pilot.
- Hold the gas valve button down for about 30 seconds.
- Release the button and check if the pilot stays lit.
If the pilot light goes out again, there might be an issue with the thermocouple. The thermocouple ensures the pilot light stays lit. It might need cleaning or replacing.
Electronic Ignition
Electronic ignition systems are common in modern camper furnaces. They replace the traditional pilot light. To test an electronic ignition system, follow these steps:
- Turn the thermostat to the “on” position.
- Listen for the ignition click.
- Check if the burners ignite.
If the burners do not ignite, there could be several issues:
- A faulty igniter
- Loose wiring connections
- A malfunctioning control board
To troubleshoot these issues, start by checking the igniter. Ensure it is clean and free of debris. Next, inspect the wiring connections for any loose or damaged wires. Finally, test the control board using a multimeter to ensure it is functioning correctly.
By following these steps, you can effectively troubleshoot the ignition system in your camper furnace. Regular maintenance and testing can help prevent future problems and ensure your furnace operates smoothly.
