How to Reset RV Furnace

As an RV owner, you rely on various systems and appliances to ensure a comfortable and enjoyable journey.

One of the most essential components of your RV is the furnace, which keeps you warm and cozy during chilly nights on the road.

However, like any mechanical device, your RV furnace may encounter issues that require troubleshooting and resetting.

In this comprehensive guide, we will walk you through the step-by-step process of resetting your RV furnace, ensuring that you can quickly resolve common problems and get back to enjoying your adventures.

So let’s dive in and learn how to reset your RV furnace effectively.

Understanding the Basics: What is an RV Furnace?

Before we delve into the process of resetting an RV furnace, let’s take a moment to understand what exactly an RV furnace is and how it operates.

An RV furnace is a heating system specifically designed for recreational vehicles, providing warmth and comfort during colder seasons.

It works by utilizing propane gas or electricity to produce heat, which is then circulated throughout the RV using a blower fan.

Signs that Your RV Furnace Needs to Be Reset

Knowing when to reset your RV furnace is crucial in maintaining its optimal performance.

Here are some common signs that indicate the need for a reset:

  1. No heat: If your furnace fails to produce warm air or if the temperature inside your RV remains consistently low despite the furnace running, a reset may be necessary.
  2. Frequent cycling: If your furnace turns on and off repeatedly without reaching the desired temperature, resetting it can help resolve the issue.
  3. Ignition failure: When your furnace struggles to ignite or doesn’t ignite at all, resetting it might help reestablish the proper ignition sequence.
  4. Blower fan issues: If the blower fan of your RV furnace isn’t working correctly, resetting the system can potentially resolve the problem.

Safety First: Precautions Before Resetting Your RV Furnace

Before you begin the reset process, it’s essential to prioritize safety.

Follow these precautions to ensure a safe and successful reset:

  1. Turn off the power: Locate the power switch or breaker associated with your RV furnace and turn it off. This step is crucial to prevent electrical accidents while working on the system.
  2. Check for gas leaks: If your RV furnace operates on propane gas, inspect for any gas leaks using a gas leak detector or soapy water solution. If you detect a leak, do not proceed with the reset and contact a professional immediately.
  3. Allow cooling time: Give your furnace sufficient time to cool down before attempting a reset. Touching hot components can result in burns or injuries.
  4. Refer to the manufacturer’s manual: Consult the owner’s manual specific to your RV furnace model for detailed instructions and safety guidelines. Different furnace models may have unique reset procedures, so it’s crucial to follow the manufacturer’s recommendations.

By adhering to these safety precautions, you can minimize the risk of accidents and ensure a secure environment while resetting your RV furnace.

How to Reset RV Furnace: Step-by-Step Instructions

Now that you’re familiar with the basics and safety precautions, let’s proceed with the step-by-step process of resetting your RV furnace.

Remember to consult your furnace’s manual for model-specific instructions.

The following instructions provide a general guideline for resetting most RV furnaces:

Step 1: Turn Off the Power Supply

Start by locating the power switch or breaker associated with your RV furnace.

This switch or breaker should be in the off position to ensure your safety while working on the system.

If you’re unsure about the location, consult your RV’s electrical system diagram or the owner’s manual.

Step 2: Locate the Reset Button

Once the power supply is off, locate the reset button on your RV furnace.

The reset button is typically situated near the furnace’s ignition control board.

It might be labeled as “Reset” or indicated by a small red button.

Step 3: Press and Hold the Reset Button

Gently press the reset button and hold it down for about 30 seconds.

While doing so, ensure that you apply consistent pressure to allow the furnace’s internal systems to reset properly.

This step is crucial in clearing any error codes or malfunctions that may be affecting the furnace’s operation.

Step 4: Release the Reset Button

After holding the reset button for the recommended time, release it and ensure that it pops back into its original position.

This signifies that the reset process has been completed.

Step 5: Restore Power Supply

Finally, restore the power supply to your RV furnace by turning on the power switch or flipping the breaker to the on position.

Wait for a few moments to allow the system to initialize and start up.

You should hear the furnace ignite, and warm air should begin flowing through the RV’s vents.

Monitor the furnace for a few minutes to ensure it is functioning correctly.

By following these step-by-step instructions, you can successfully reset your RV furnace and restore its normal operation.

However, if the issues persist even after resetting, it may be necessary to consult a professional for further inspection and repairs.
