Common Furnace Problems
When the chill of the night seeps into your RV, the last thing you want is a malfunctioning furnace. But like any appliance, your Keystone RV furnace might occasionally act up. Knowing the most common furnace problems and how to troubleshoot them can save you time, money, and stress on your road trips.
Furnace Not Turning On
Nothing feels more frustrating than flipping the switch and getting no response. Start by checking the basics: is your RV’s thermostat set to “heat”? Is the furnace properly connected to the power source?
If those seem fine, inspect your RV’s fuse box for blown fuses or tripped breakers. A faulty fuse is a common culprit and easy to replace. Also, ensure your propane tank isn’t empty—no fuel means no heat.
Blower Running Without Heat
If your blower is running but no warm air is coming out, it could be a sign of a failed ignition. A dirty or misaligned igniter might prevent the furnace from lighting properly. Clean the igniter gently and see if that resolves the issue.
Another reason could be a clogged burner orifice. Dirt and debris can block the flow of propane. A quick cleaning can often get things back in working order.
Uneven Heating In The Rv
Does one part of your RV feel like a sauna while another feels like a freezer? Uneven heating is often caused by blocked vents or poor air circulation. Make sure nothing is obstructing the furnace vents inside your RV.
If the vents are clear, check the ductwork for damage or leaks. A small tear in a duct can redirect warm air away from where you need it most. Seal any gaps with heat-resistant tape to fix this issue.
Furnace Making Unusual Noises
Odd noises coming from your furnace can be unsettling. A rattling sound might indicate loose screws or components. Tightening these up could solve the problem.
High-pitched squealing usually points to worn-out blower motor bearings. Lubricating the motor or replacing the bearings can silence the noise. If you hear banging or popping, it could signal a more serious issue, like a heat exchanger problem—get it checked by a professional.
Addressing these common furnace problems promptly will keep your RV cozy and comfortable. Have you encountered any of these issues before? If so, which quick fix worked best for you? Share your experience in the comments below!

Checking Power Supply
Getting your Keystone RV furnace back in working order often starts with checking the power supply. A furnace that doesn’t heat could simply be a sign of interrupted electrical flow. Whether it’s a drained battery, a blown fuse, or a faulty thermostat, understanding and troubleshooting the power supply can save you time and frustration.
Inspecting Battery Voltage
Start by ensuring your RV’s battery is adequately charged. A low or dead battery can prevent the furnace from operating correctly. Use a multimeter to measure the voltage. A fully charged battery typically reads around 12.6 volts.
If the reading is significantly lower, recharge your battery or consider replacing it if it no longer holds a charge. Have you accidentally left lights or appliances running? This simple mistake can quickly drain your battery.
Examining Fuse And Circuit Breaker
Check the fuse box and circuit breaker panel in your RV. Look for any blown fuses or tripped breakers. A blown fuse may appear burnt or have a broken filament inside.
Replace damaged fuses with ones of the same rating. Reset any tripped breakers by flipping them off and then back on. These small fixes often restore power to your furnace immediately.
Did you recently experience power fluctuations or connect to a faulty shore power source? Such events can easily trigger fuse or breaker issues.
Testing The Thermostat
The thermostat is another critical piece of the puzzle. Make sure it’s set to “heat” mode and the temperature is high enough to activate the furnace. Sometimes, a simple adjustment solves the problem.
If the thermostat doesn’t respond, it may need recalibration or replacement. Use a screwdriver to remove the thermostat cover and inspect for loose wires or corrosion. Tighten connections if necessary.
Could it be that your thermostat’s batteries are dead? Always check this first—it’s an easy fix that’s often overlooked.
When troubleshooting, don’t rush. Take each step carefully. Have you encountered a similar issue before? Share your insights and let others know how you resolved it. Troubleshooting is all about patience and persistence!
Inspecting The Furnace Components
Regular maintenance of your Keystone RV furnace ensures steady and efficient performance. Inspecting the furnace components can help identify common issues before they escalate. This process involves a closer look at critical parts like the burner assembly, igniter, flame sensor, and blower motor. Keeping these components clean and functional ensures your furnace operates smoothly.
Cleaning The Burner Assembly
The burner assembly is crucial for proper heat generation. Dust and debris often accumulate, affecting its performance. Start by turning off the furnace and disconnecting the power. Remove the burner assembly carefully to avoid damaging it. Use a soft brush or compressed air to clean off dirt and buildup. Ensure all ports are clear of obstructions. A clean burner assembly improves combustion efficiency and reduces the risk of issues.
Checking The Igniter And Flame Sensor
The igniter and flame sensor are essential for ignition and flame detection. Dirt or corrosion can prevent them from functioning correctly. Gently remove the flame sensor and igniter with the proper tools. Use fine sandpaper or a clean cloth to remove buildup. Avoid using excessive force to prevent damage. Reinstall them securely and confirm they are properly aligned for accurate operation.
Examining The Blower Motor
The blower motor circulates warm air throughout your RV. A faulty motor can disrupt airflow and heating. Inspect the motor for signs of dirt, wear, or damage. Check the blower wheel for dust or debris that may hinder performance. Lubricate the motor bearings if required, following the manufacturer’s guidelines. Ensure the motor spins freely and operates without unusual noises.
Airflow Issues And Filters
Keystone RV furnaces are essential for staying warm during cold seasons. Proper airflow ensures the furnace heats your RV efficiently. Clogged filters or blocked vents can disrupt airflow, causing uneven heating or system failures. Addressing these issues promptly can improve performance and comfort.
