Heartland RV Furnace Problems

When it comes to your Heartland RV furnace, there may be several problems that can arise.

Let’s explore some of the most common issues and discuss the steps you can take to troubleshoot and resolve them.

Insufficient Heating

Are you finding that your Heartland RV furnace is not producing enough heat to keep you warm?

This can be a frustrating problem, especially when you’re relying on your furnace for comfort during colder temperatures.

Possible Causes:

  • Dirty Air Filters: One of the most common reasons for insufficient heating is dirty air filters. Over time, dust and debris can accumulate, obstructing the airflow and reducing the furnace’s efficiency.
  • Thermostat Issues: It’s also possible that there may be an issue with the thermostat, such as incorrect temperature settings or a faulty sensor.
  • Propane Supply: If you’re using propane as the fuel source for your furnace, ensure that you have an adequate supply. Running out of propane can result in reduced heating capabilities.


To address this problem, follow these steps:

  1. Check Air Filters: Locate the air filters in your Heartland RV furnace and inspect them for dirt and debris. If dirty, clean or replace the filters as recommended by the manufacturer.
  2. Inspect Thermostat: Ensure that the thermostat is set to the desired temperature and is functioning correctly. If necessary, replace the batteries or consult the manufacturer’s instructions for troubleshooting.
  3. Verify Propane Supply: If your furnace relies on propane, ensure that you have enough fuel. Check the propane tank levels and refill if necessary.

Furnace Not Igniting

If your Heartland RV furnace fails to ignite, it can be a significant inconvenience, leaving you without the heat you need.

Let’s explore the potential causes and solutions for this problem.

Possible Causes:

  • Ignition System Malfunction: The ignition system, including the igniter or pilot light, may be faulty or require cleaning.
  • Electrical Issues: A blown fuse, tripped circuit breaker, or loose electrical connections can prevent the furnace from igniting.
  • Gas Valve Problems: If there is a problem with the gas valve, the furnace may not receive the necessary gas supply for ignition.


Follow these steps to troubleshoot and address the issue:

  1. Inspect Ignition System: Check the igniter or pilot light for any signs of damage or dirt buildup. Clean the components as recommended by the manufacturer.
  2. Check Electrical Connections: Ensure that all electrical connections are secure and not damaged. If you find a blown fuse or tripped circuit breaker, replace or reset them accordingly.
  3. Verify Gas Supply: Confirm that the gas valve is open and that there are no obstructions or leaks in the gas line. If you suspect a gas valve issue, consult a professional for repair or replacement.

Uneven Heating

Are you experiencing inconsistent heating throughout your Heartland RV?

Uneven heating can lead to discomfort, making it essential to identify and resolve the underlying cause.

Possible Causes:

  • Blocked Vents: Obstructed vents or air registers can disrupt the airflow and result in uneven heating.
  • Ductwork Issues: Damaged or poorly insulated ductwork can lead to heat loss, causing varying temperatures within your RV.
  • Inadequate Furnace Sizing: If your furnace is undersized for your RV, it may struggle to heat the space evenly.


To address uneven heating, consider the following steps:

  1. Check Vents and Air Registers: Ensure that vents and air registers are not blocked by furniture, rugs, or other objects. Clear any obstructions to allow for proper airflow.
  2. Inspect Ductwork: Examine the ductwork for any visible damage or signs of poor insulation. Seal any leaks and insulate the ducts as necessary.
  3. Evaluate Furnace Size: If you suspect that your furnace may be undersized, consult with a professional to determine the appropriate size for your RV.

Blower Fan Issues

The blower fan is an integral component of your Heartland RV furnace, responsible for distributing heated air throughout your vehicle.

Let’s explore common problems associated with the blower fan and their potential solutions.

Possible Causes:

  • Motor Problems: A malfunctioning motor can prevent the blower fan from operating correctly.
  • Worn or Damaged Belt: If the blower fan is belt-driven, a worn or damaged belt can impede its functionality.
  • Electrical Issues: Faulty wiring or a defective capacitor can affect the blower fan’s performance.


Consider the following steps to address blower fan issues:

  1. Inspect Motor: Check the blower fan motor for any signs of damage or irregularities. If you notice any issues, consult a professional for repair or replacement.
  2. Replace Belt: If the blower fan is belt-driven, examine the belt for wear and tear. Replace the belt if necessary, following the manufacturer’s instructions.
  3. Check Electrical Connections: Ensure that all electrical connections related to the blower fan are secure and undamaged. If you suspect an electrical issue, consult a professional for assistance.

Excessive Noise

Excessive noise coming from your Heartland RV furnace can be disruptive and may indicate underlying problems.

Let’s explore the potential causes and solutions for excessive furnace noise.

Possible Causes:

  • Loose Components: Loose components within the furnace, such as screws or panels, can produce rattling or vibrating sounds.
  • Blower Fan Issues: A damaged blower fan or motor can result in unusual noise during operation.
  • Ductwork Problems: Damaged or improperly installed ductwork can cause air turbulence and generate noise.


Follow these steps to address excessive furnace noise:

  1. Tighten Components: Inspect the furnace for any loose components and tighten them accordingly. Ensure that screws, panels, and access doors are secure.
  2. Service Blower Fan: If the blower fan or motor is causing the noise, consider contacting a professional for inspection and potential repair or replacement.
  3. Inspect Ductwork: Examine the ductwork for any visible damage or signs of improper installation. Repair or reposition ducts as necessary to reduce noise.


Why is my Heartland RV furnace not turning on?

There could be several reasons for this issue, such as a blown fuse, tripped circuit breaker, thermostat malfunction, or a problem with the ignition system. Check these components and consult the manufacturer’s instructions for troubleshooting.

How often should I clean or replace the air filters in my Heartland RV furnace?

It is recommended to clean or replace the air filters every three to six months, depending on usage and environmental conditions. Regular maintenance of the air filters ensures optimal furnace performance.

Why is my Heartland RV furnace producing a strange odor during operation?

A foul odor can indicate dust or debris burning off within the furnace, which is common after periods of inactivity. However, if the odor persists or smells like gas, it is crucial to turn off the furnace and seek professional assistance immediately.

Can I troubleshoot and repair my Heartland RV furnace myself?

While some minor issues can be addressed by RV owners, it is recommended to consult the manufacturer’s instructions or seek professional assistance for complex repairs. Improper handling of furnaces can pose safety risks.
