Common Issues in Airxcel RV Furnaces

Furnace problems can dampen your RV adventures. Here’s a look at some common issues you may encounter and how to troubleshoot them.

Ignition Problems

Ignition problems often prevent your Airxcel RV furnace from starting. Check the following:

• Thermostat Settings: Ensure the thermostat is set to a temperature higher than the current room temperature.
• Power Supply: Verify that the furnace is connected to a power source and that all fuses are intact.
• Flame Sensor: Clean the flame sensor. A dirty sensor can cause the furnace to shut down after failing to detect a flame.
• Propane Supply: For propane models, check whether the propane tank is full and the valve is open.

Insufficient Heating

Insufficient heating leads to an uncomfortable environment inside your RV. Investigate these possible causes:

• Air Filters: Dirty filters restrict airflow. Clean or replace them regularly to improve efficiency.
• Duct Blockages: Inspect ducts for obstructions or debris. Clear any blockages to ensure warm air flows freely.
• Temperature Setting: Confirm the thermostat is set to a suitable level. Lower settings will result in lower temperatures inside.
• Insulation Issues: Check the insulation on your RV. Insufficient insulation can cause heat loss and reduced comfort.

Unusual Noises

Unusual noises can indicate issues within your furnace. Pay attention to these sounds:

• Rattling: A rattling noise may signal loose components. Tighten any loose screws or parts to eliminate the noise.
• Humming or Buzzing: Humming can suggest electrical problems. Inspect electrical connections and connections to the blower fan.
• Popping or Banging: These sounds often indicate a problem with the ignition sequence or an obstruction in the burner. Inspect the burner for blockage or dirt buildup.

By addressing these common issues, you can enhance the performance of your Airxcel RV furnace and maintain a comfortable environment during your travels.

Troubleshooting Steps

Follow these troubleshooting steps to diagnose and resolve issues with your Airxcel RV furnace.

Checking Power Supply

1. Inspect Power Source: Ensure your RV is connected to a reliable power source. Check the circuit breaker for any tripped switches.
2. Test Power Connections: Examine power cables for any signs of wear or damage. Ensure connections are tight and secure.
3. Ensure Battery Functionality: If you’re using battery power, check battery levels and connections. Replace or recharge the battery if necessary.

Inspecting Thermostat Settings

1. Confirm Thermostat Operation: Set your thermostat to a higher temperature to trigger the furnace. Verify that it displays power and responds to adjustments.
2. Check for Proper Settings: Make sure the thermostat is set to “heat” mode. Ensure the fan setting matches your desired operation (auto or continuous).
3. Replace Batteries: If your thermostat uses batteries, replace them to avoid any power issues.

1. Inspect Ducts for Blockages: Check all ducts for any obstructions, including dust and debris. Clean out any blockages that prevent airflow.
2. Ensure Vent Openings Are Clear: Confirm all vents are open and unobstructed. Check for any furniture or items that may be blocking airflow.
3. Evaluate Insulation: Examine duct insulation for damage or gaps. Proper insulation helps maintain heat within the system, improving efficiency.

Maintenance Tips for RV Furnaces

Maintaining your Airxcel RV furnace ensures optimal performance and longevity. Regular checks and simple tasks keep it running smoothly. Here are essential maintenance tips for your furnace:

Regular Filter Cleaning

• Inspect Filters Monthly: Check your furnace filters every month, especially during heavy use. Dirty filters reduce airflow and efficiency.
• Clean or Replace: If filters show dirt buildup, clean or replace them. Opt for high-efficiency particulate air (HEPA) filters for better results.

Check Ventilation

• Clear Vent Openings: Confirm that all vent openings are free from obstructions. Leaves, dirt, and debris can block airflow.
• Inspect Ducts: Examine ducts for blockages or damage. Blocked ducts can lead to inconsistent heating.

Thermostat Maintenance

• Test Temperature Settings: Regularly test that your thermostat accurately reflects desired temperatures. Adjust settings as necessary.
• Replace Batteries: If your thermostat uses batteries, replace them annually to prevent power failures.

Inspect Flame Sensor

• Clean the Flame Sensor: A dirty flame sensor can cause ignition problems. Clean it with a soft cloth to ensure optimal performance.
• Check for Corrosion: Inspect the sensor for any signs of corrosion. Replace it if corrosion is present.

Review Propane Supply

• Check Propane Levels: Use a gauge to monitor propane levels in your tank. Low propane can cause heating issues.
• Inspect Connections: Examine propane connections for leaks. Use soapy water on connections; bubbles indicate leaks.

• Schedule Inspections: Have a qualified technician inspect your furnace once a year. They can spot potential issues before they become major problems.
• Clean Combustion Chamber: Professionals can clean the combustion chamber to enhance efficiency and safety.

By following these maintenance tips, you keep your Airxcel RV furnace in top shape, ensuring a cozy environment during your getaways. Staying proactive with maintenance prevents small issues from snowballing into larger, costly repairs.
