5 Troubleshooting Methods Explained

Before attempting a reset, it is important to troubleshoot the Suburban RV furnaces. Pressing the reset button alone may not resolve certain technicalities. Ignoring these issues can result in the furnace starting to function unexpectedly.

Follow the instructions below to address the problems that triggered the reset button.

1. Refill Fuel Tank

The Suburban RV furnace relies primarily on a 12V power source for operation. In the event of a drained battery, the furnaces cannot ignite. One can trigger the reset button to determine whether the battery has been depleted or lacks power.

  • The initial step to take is inspecting the battery of your Suburban RV furnace.
  • Assess the remaining charge by utilizing a multimeter.
  • Moreover, acquire a replacement if the battery consistently exhibits a low charge level.
  • If the device functions properly, ensure the battery is recharged before pressing the reset button.

Following these steps can effectively troubleshoot and address potential issues with your RV furnace.

2. Clean Gas Valves

Weather conditions like rain and dust can cause blockages or clogged gas valves. Consequently, fuel flow may be hindered, resulting in difficulties when igniting the furnace. Start by examining the gas valves to check for any obstructions.

  • If a blockage is present, open the valves, thoroughly clean them using pressure, and ensure no residual water.
  • After completing this process, connect your Suburban RV furnace to a power source and press the reset button.
  • In addition to inspecting the gas valves, examining the entire gas line for potential blockages is essential.
  • Clear any debris or obstructions that may be hindering the proper flow of the fuel tank. Ensure that the gas line is also free from any damages or leaks.

3. Thoroughly Check Air Filters and Replace them if Needed

RV air filters accumulate dirt and debris rapidly. Their malfunctioning strains the Suburban RV furnace and trips the reset button. To resolve these issues:

  • Replace them every three months to maintain optimal functionality.
  • Inspect and deep clean them if the furnace does not work well.
  • After cleaning, reset these to their original position to ensure proper functioning.
  • Clean and properly working filters ensure the efficient operation of cold air in an RV.
  • They contribute to a more comfortable and healthier indoor environment during travels.

4. Change Or Wipe Rust From the Flame Sensor

The metal flame sensor in the Suburban RV furnace is prone to rust, dirt, and debris accumulation, leading to ignition problems. Repeated ignition failures result in the activation of the reset button.

  • To address this issue, examine the flame sensor plate for any indications of dirt grains buildup.
  • If feasible, thoroughly clean the sensor to remove any contaminants.
  • In cases where the sensor is damaged, replace it with a new one before pressing the reset button to ensure proper functionality.
  • Regular inspection and maintenance of the flame sensor can help prevent ignition issues and promote the efficient operation of the RV furnace.

5. Clean Air Vents For Better Airflow

Maintaining proper airflow is crucial to prevent overheating of the furnace. Before proceeding with the reset, it is important to ensure that all air vents are clear to prevent the furnace from tripping again.

  • Check each vent to confirm that there are no obstructions or blockages that could impede the airflow.
  • Remove any debris or objects that may be hindering the ventilation.
  • Ensuring unobstructed airflow can help it operate efficiently and reduce the risk of overheating and subsequent trips.
