RV Furnace: What It Is
If you’re a fan of traveling and camping, an RV is a good investment. Although RVs come with fully-equipped kitchens and bathrooms, the thermostat usually only keeps your RV at a comfortable temperature, and it may not work as well as it should in harsh temperatures. An RV furnace is the answer to such challenges. You don’t have to depend on campsite facilities or start a fire to keep you warm at night. An RV Furnace is an essential appliance for anyone who wants to spend time in their RV throughout the year.
An RV furnace is similar to a home furnace but designed to be smaller and used in an RV. It uses Propane to generate heat and a blower to circulate that heat through the RV. The furnace draws cool air into the heating system through a series of vents, where it’s then heated by the propane burner. Once heated, the warm air is pushed into the RV through a system of ducts by the blower. An RV furnace is a stand-alone unit and not tied to any external system. An RV furnace is an independent system, It can be used when your RV’s electrical systems aren’t powered. [1]
Regular maintenance is essential to ensure that your RV furnace functions properly, it’s better to do maintenance during the off-season. It’s essential to follow the manufacturer’s recommendations in terms of furnace maintenance.
RV furnaces come in different sizes, and the size you choose should be determined by the size of your RV. If you own a larger RV, then you need a larger furnace with greater heating capacity. RV furnace efficiency is another key consideration; the higher the furnace efficiency, the less propane it will require to heat your RV. We recommend doing this if you plan on spending many nights in your RV or in cold temperatures.
An RV furnace is an essential component for anyone who enjoys extended outdoor activities and wants to remain warm on those chilly nights. An RV furnace is not only beneficial in cold areas, but it is also important for those who enjoy long-term camping. Proper furnace maintenance is not only necessary for your comfort, but it is also crucial for your safety. So, enjoy your RV adventures with a reliable furnace and safe operation.

Top Reasons Why It Doesn’t Work
For RV enthusiasts, one of the perks of having a motorhome is that it provides all the comforts of a home, including a reliable heating system. But RV furnace problems can be frustrating, especially if you’re on a trip and it suddenly stops working. Without proper knowledge, it can be a challenge to diagnose and fix the issue. Here we discuss the top reasons why RV furnaces stop working and offer helpful tips on how to troubleshoot and solve the problem.
- Thermostat Issues – Probably the most popular reason why RV furnaces stop working is a malfunctioning thermostat. If you notice that your furnace is not turning on or shutting off at the right time, it could be because of a problem with the thermostat. You can check this by testing the system using a multimeter or replacing the batteries in your thermostat. Also, make sure that the thermostat is set correctly and that it’s not obstructed by any obstacles.
- Airflow Obstructions – Another common problem with RV furnaces is when there are obstructions in the airflow system. This could be due to dirty filters, blockages in the air ducts, or debris in the furnace’s blower wheel. If the air doesn’t flow properly, the furnace will struggle to run correctly, resulting in poor heating or no heating at all.
- Propane System Problems – If your RV furnace relies on propane, the system could be the reason why it’s not working correctly. Common propane system issues include low propane pressure, faulty propane regulator, or air in the propane lines.
- Ignition and Gas Valve Problems – If your furnace makes a clicking noise but doesn’t start up, the problem may be with the ignition or gas valve. The most common culprits for ignition problems are a dirty flame sensor or a corroded igniter. Gas valves, on the other hand, can malfunction due to gas leaks, blockages, or electrical faults.
- Poor Maintenance and Upkeep – Finally, the lack of proper maintenance and upkeep can lead to furnace problems. It’s essential to keep your RV furnace clean and perform regular maintenance, including cleaning or replacing the air filters, cleaning the blower wheel, and removing any debris in the furnace. Also, be sure to get your furnace inspected by a professional technician at least once a year to prevent any significant issues.
Knowing the top reasons why RV furnaces stop working and how to troubleshoot them can save you loads of frustration and money. When in doubt, it’s always best to contact an experienced RV technician to diagnose and repair your RV furnace.

How to Maintain RV Furnace
Your RV furnace is one of the most important components in keeping you warm and comfortable on your camping trips. As an RV owner, it’s essential to understand how to maintain it properly. Not only does sticking to a maintenance routine make your furnace more efficient, but it also prolongs its lifespan, preventing costly repairs. We’ve compiled a list of tips and tricks to ensure that your RV furnace stays in top shape.
- Regular Cleaning
The first step in maintaining your RV furnace is regular cleaning. Dust, dirt, and debris can clog the furnace filter, reducing airflow throughout the unit, and requiring more energy to operate. This not only leads to increased energy consumption but also causes overheating, which can ultimately lead to the failure of your furnace. We suggest cleaning or replacing your furnace filter every 3 months or at the beginning of each camping season.
- Inspection
A yearly inspection should be performed to ensure that every component of your furnace is working correctly. This should include the propane line, furnace ducts, and the burner unit. Be sure to check for any cracks or damage in the ducts, as well as any signs of rust or corrosion. Hiring a professional to carry out the inspection can help identify any underlying issues and keep your furnace in optimal condition.
- Lubrication
Keeping the blower motor lubricated can also help maintain the efficiency of your RV furnace. A well-lubricated motor runs more quietly and reduces resistance, allowing the motor to operate more smoothly. This, in turn, leads to decreased energy usage. Check your furnace owner’s manual for instructions and recommended types of lubrication.
- Electrical Connections
Proper maintenance of electrical connections is essential to keep your furnace running smoothly. Over time, connections can become loose, corroded, or damaged, causing malfunctions. Check for loose connections and ensure all electrical connections are secure.
- Thermostat Settings
Your thermostat settings also play an essential role in furnace maintenance. Operating in temperatures well below or above the recommended range puts undue stress on your furnace’s mechanical parts, reducing its overall lifespan. Be sure to stick to the recommended temperature range, as stated in your furnace owner’s manual.
Maintaining your RV furnace is essential in ensuring your comfort level while camping. Regular cleaning, lubrication, and inspection, along with proper electrical connections, and thermostat settings, can reduce the risk of furnace failure while decreasing energy usage and prolonging its lifespan. By implementing these tips, you can keep your RV furnace operating smoothly for years.
FAQ
Why does my furnace keep turning off in my RV?
Furnace issues in an RV could be a result of several factors. The most common cause could be insufficient airflow. RVs require proper ventilation, and if the air isn’t flowing optimally, it can lead to the furnace shutting off. Another common problem is gas supply issues. Your RV furnace probably runs on propane, and if you’re running out of fuel or there are leaks in your gas lines, the furnace can shut off. Malfunctioning thermostats or control boards can also lead to furnace shutdowns in RVs.
Why does my furnace keep shutting off after a few seconds?
A dirty or damaged flame sensor can cause the furnace to shut off as a safety feature to prevent gas leaks. The thermocouple could also be the culprit. If the thermocouple isn’t sensing the heat from the pilot light, it could cause the furnace to shut off within a few seconds. Other causes could include dirty burners, blocked vents, or a malfunctioning thermostat.
How do I fix my furnace that throws out cold air?
The most straightforward solution for a furnace that throws out cold air is to replace the air filter if it’s dirty or clogged. If the issue persists, inspect the thermostat and ensure that it’s turned on and set to the desired temperature. Check to see that the breaker controlling your furnace is on. Confirm if your furnace is fed with sufficient fuel and assess whether the thermocouple and flame sensor are working correctly.
