Motorhome Gas Regulator Problems

Motorhome Gas Regulator Problems

Many people come with the problem that their gas regulator does not work appropriately in the motorhome.

The installation of gas regulators in this vehicle is necessary because it helps control gas-fueled parts like the stove and brings hot water for showers.

Motorhome Gas Regulator Problems include low, unsteady, and orange flames from the burner, stove, and heaters. In addition, there is a stuck-in regulator due to contaminated gas with humidity and some leaks in its outer body. Furthermore, there is an unwanted increase and decrease in its pressure due to the accumulation of debris and poor installation. The rust on the burners, broken valves, loose springs, and tighten screws are a few other issues with the gas regulator. 

It has two types one is the butane system, the second is the propane system which is the most widely used one.

There is a valve, a filter, knob, a diaphragm, spring, and many other small components in its constitution that may cause malfunctioning.

By proper calibration, care and maintenance, you can enjoy its full functioning of stopping the gas flow till it reaches a limit.

Low Flame

When gas regulators become sticky, they allow little movement of gas from the cylinder to the stove and other appliances.

This condition will result in low temperatures and little flame on the stove, burners of heaters, and geysers.

This stickiness is the most common issue, and you will feel restless more in the winter season because showers become impossible.

You can reset the regulator by turning off the gas tank to release the pressure and remove the burner’s lid.

It is easy to reduce this issue by disconnecting all the parts like the hose and burner, but make the accurate reconnection after the treatment.

At times, the flame does not reach its original height demanding its replacement with a new and better quality one.

Gas Leakage

Any damage or hole in the regulator’s outer body brings the leakage of the gas, and as a result, the appliances do not receive a sufficient amount.

The insufficient amount of gas holds an issue in burning the stove because it makes the cooking process more time-consuming.

The leakage also brings a bad smell to the motorhome, and it can prove dangerous in providing harm to the family.

You have to check the burner, hose, and tank for any damage, and in this inspection, soap liquid works well.

The appearance of bubbles after soapy spray on these parts is a clear-cut symbol of leakage from the burners.

Sometimes, there are holes in the nozzle bringing the problem that even after the full filled tank, the stove does not receive it.

In this situation, you can apply some sticky sealing material on the damaged parts, but damage demands its replacement.

Building of cold vapors

Motorhome gas regulator doesn’t need to be locked in the winter due to the cold outside temperature.

The humidity can make the system frozen because the cold vapors in the flow path lead to moisture condensation.

As you switch on the burner and stove, the cold vapors in the pipes link with the outside humidity that makes it stuck in.

The over-filled tank with gas and the damaged tank is equally responsible for this freezing problem and demand proper maintenance.

This moisture condensation is common in motorhomes, and you cannot get rid of this problem.

The only remedy for this problem is to avoid the direct exposure of water with this device that can reduce the risk of contamination.

Orange flames

An accurately working device gives a blue flame from the stove allowing its smooth and steady movement.

There are hose and valves in the motorhome gas regulator assembly, and a defect in these parts can bring your stove with the orange color flames.

This orange flame results from the non-continuous gas flow through the valves, restricting its movement from the knob.

There are flames on the ports and air intakes of the burner leading to a black sooty appearance all around the parts.

In this case, the tubes and shutters demand some easy adjustments but require all your focus and know-how.

You have to clean the clogged areas by unscrewing the structural components in the assembly of this regulating device.

Unwanted increase in gas pressure

Sometimes, there is an issue that you set the pressure for your device, but it exceeds this set point, and two reasons are responsible for this.

The first reason is the accumulation of the debris at the time of installation, and it starts flowing through the system.

This particulate interference creates a gap between the poppet and seat, bringing an unwanted increase in the gas pressure.

This process is known as creeping, and it becomes more severe when the components present in the downstream assembly are not up to the mark for the set pressure.

There is a filter near the valve, and any damage to its surface brings this problem more frequently.

You can fix it by adding the device precisely with your full attention and cleaning the components for perfect working.

A small act of ignorance can bring you more dangerous problems for the motorhome and your family.

The second reason for the unwanted pressure increase is visible when inlet pressure variation brings the variation pressure at the outlet.

It is actually the supply pressure effect causing the unwanted increase at the outlet due to the decrease in inlet pressure.

High pressure and twin-stage motorhome gas regulators are suitable in this situation because they can manage this pressure sufficiently.

You can install two regulators in a series to have a better working device for your stoves and heaters for the home on wheels.

Inspect the damaged filter surface to avoid the contamination of the dirt particles with the lubricating fluid.

Decrease in gas pressure

Suppose you set pressure of about 70 psi for the cooking stove operation, but it starts to decrease, usually difficult to analyze.

This pressure drop is due to the miss-fitted and less efficient motorhome gas regulator that does not match the appliance you want to operate.

This dropping of gas pressure is known as droop, and it is mandatory to inspect it on an urgent basis without any late.

You can check the needed appropriate size of the device with the help of a flow curve generator tool that is perfectly suitable in this situation.

The selection of a definite-sized device with a sufficient flowing coefficient is helpful to avoid this unwanted decrease.

You have to check that the supplier installs the best product in your RV that provides you with home-like facilities.

Dome-loaded regulating devices are more prone to these sudden variations, and you must replace them with spring regulators.

Unsteady flow of gas

The pulsation is the most frequently occurring problem in the gas pressure regulating apparatus in the motorhome.

Improper venting is the leading cause of this technical issue of pulsation leads to an unsteady regulation of pressure.

The use of more than one elbow and long vent pipes creates a hurdle in controlling the pressure.

You can increase the diameter of the vent line, and it is better to use a small pipe and a few elbows for efficient working.

Since its location in the pipelining is not precise, such as too close to the pipe, it causes turbulence in the smooth pressure flow.

You have to make sure that it is present at the right place concerning the tees and elbows in the pipelining that connects the device with the appliances.

More than two regulators in a motorhome can create pulsation because these two will have a competition between each other.

The distance between this regulating device and the appliance can be the damaging reason behind pulsation in the flow.

The miss-match capacity of the device with the appliance creates an unsteady flow of gas leads to pulsation.

The selection for the perfect combination and appropriate distance between two components in the assembly can help you to reduce pulsation.

Rust on the burner

The accumulation of water inside due to humidity and the dirt is responsible for black rust mass inside the burners, cylinders, and around the knob. This is among the common problems with the gas regulators in RVs.

Rust blocks its functioning, resulting in a stuck-in position on a long journey away from your home.

The lack of a significant lubricating agent is the leading cause of the corrosion inside the motorhome regulator.

You have to clean the surface and make sure that there is suitable dielectric grease around the screws and bolts.

Broken valve

A valve in the gas regulating device in the motorhome controls the gas pressure and stops if it exceeds a limit.

It brings safety to your RV and helps you feel relaxed for cooking and having a shower with hot water in this mobile home.

To examine the broken valve, unscrew the assembly containing the different components, and check for any fault.

Defective spring and screws

The loose spring brings a faulty movement for the spring that creates an annoying sound coming from the vehicle.

A cracking sound comes from the cooking area, a small part of the motorhome, due to tight screws and lack of lubricating agent.

You have to make sure that springs and screws are working with perfection because it is annoying when a popping noise comes by switching on the stove.
