Understanding and Troubleshooting Common Issues with Propane Generators

Propane generators are a popular and convenient source of power for RVs and motor homes. However, like any other equipment, they can experience issues that affect their performance. In this article, we will explore the common problems faced by propane generators and provide troubleshooting tips to help you resolve them.

1. Introduction

Propane generators have become a vital component of RVs, providing power for various appliances and systems, including air conditioners. However, when these generators encounter problems, it can be frustrating and hinder your overall RV experience. This article aims to address common issues faced by propane generator owners and guide you through the process of troubleshooting and resolving these problems effectively.

2. Understanding Propane Generators

Before diving into troubleshooting, it's essential to have a basic understanding of how propane generators work. Propane generators can be classified into two types: liquid-fed and vapor-fed generators.

2.1 Liquid-Fed vs Vapor-Fed Generators

Liquid-fed generators utilize liquid propane stored in the propane tank. The liquid propane is pumped into the generator unit, where it is converted into a vapor or gas to fuel the generator. On the other hand, vapor-fed generators directly use propane in its gaseous form.

The type of generator you have will affect the troubleshooting tactics that you or a technician can undertake. Identifying the brand and model of your generator is crucial as it provides valuable insights into potential issues and their corresponding solutions.

3. Troubleshooting a Propane Generator

When troubleshooting a propane generator, it's crucial to conduct electrical measurements to ensure the generator is outputting the correct frequency and voltage. This step is necessary to determine if the generator is functioning correctly under idle conditions and when a load is applied.

3.1 Electrical Measurements

To measure the voltage, current flow, and frequency, you will need specialized equipment. It is advisable to seek the assistance of a technician or use a professional service facility equipped with a generator load bank. A generator load bank is essential as it assists in accurately setting up the generator's mechanical adjustments based on its electrical response.

3.2 Importance of Generator Load Bank

A generator load bank is a device that provides an electrical load to the generator. By simulating real-world conditions, it allows technicians to measure the generator's performance accurately. If a service facility does not have a generator load bank, it is advisable to seek an alternative facility that can perform this crucial step.

4. Potential Issues and Solutions

Several components of a propane generator can cause it to sputter or run out of fuel when a load is applied. Here are some potential problem areas to consider:

4.1 Carburetor Problems

The carburetor is a vital component that mixes fuel and air to create the combustible mixture required by the generator. Issues with the carburetor, such as clogs or maladjustments, can prevent the proper delivery of fuel, resulting in poor generator performance. Cleaning or adjusting the carburetor may be necessary to resolve these problems.

4.2 Governor Issues

The governor regulates the speed and power output of the generator. Problems with the governor can lead to power inconsistencies or difficulty handling a load. Inspecting and adjusting the governor settings, as well as checking for any mechanical issues, can help resolve these problems.

4.3 Internal Engine Problems

If your generator has been in use for a significant amount of time, internal engine problems may arise. These can range from worn-out components to more severe issues. A qualified technician will need to perform a thorough examination to determine the specific problem and recommend appropriate solutions.

4.4 Fuel Solenoid Valve

All propane generators have a device known as an electric fuel solenoid valve. This valve must receive a constant 12-volt battery power supply through the generator's control system. Loss of voltage to this device can cause the generator to be starved of fuel. It is essential to ensure that the voltage to the solenoid valve is not interrupted, especially when a load is applied.

5. Considerations for Proper Setup

To ensure optimal performance of your propane generator, several factors need to be considered during its setup.

5.1 Setting up Regulators

If you have replaced the exterior regulators, it is crucial to ensure they are set up to the proper pressure according to the specifications of your generator. A mismatch in pressure can lead to fuel delivery issues and affect your generator's performance.

5.2 Propane System Tap

Determining where the generator taps into the propane system is essential. It can be either before or after the regulator on the coach. Knowing the location helps in diagnosing potential issues with fuel delivery.

6. The Role of Filters in Propane Generators

Contrary to Deborah's query, propane tanks do not have filters built into them. However, a faulty coach regulator propane regulator could be the source of the problem. If all other troubleshooting steps have been exhausted, it is worth rechecking the regulator system and ensuring it is functioning correctly.

7. Conclusion

Propane generators are reliable power sources for RVs, but they can encounter various issues. By understanding the inner workings of these generators and following the troubleshooting tips provided in this article, you can resolve most problems and ensure your propane generator functions optimally. If troubleshooting becomes challenging, it is recommended to consult a qualified technician for assistance.
