How To Troubleshoot Propane Heaters

Propane heaters are very useful and they are becoming very popular. They are used to keep the above body temperature well heated. They are designed in such a way that they provide a warmer and even more heated environment.

Propane heaters have got sensitive controls that help you to regulate the flow of gas. This in turn keeps the room comfortable. These controls are very sensitive and therefore one needs to use them with proper knowledge and instructions and take special care while using them.

If your propane heater is not working properly then the problem is only with these controls most of the time. When your propane heater starts to malfunction the fault mainly lies with the controls as they are very sensitive. The gas or the ignition system can be at a fault or the problem can also be with the clogged pipe, the standing pilot that flickers or goes out, or even with the electronic spark that doesn’t spark. These problems can be frustrating but the best thing is the repair is very easy.

Today I am going to explain to you the different types of problems that can occur to a propane heater and in such problems what are the best ways to overcome them. We will first understand the working of a propane heater and then we will look at the most common issues that occur. We will learn how to troubleshoot a propane heater in detail.

Working of a Propane Heater

To understand the working of a propane heater is very simple and all you need to do is read this carefully.

When the thermostat gets on or it is turned up, a little electric signal gets transferred. This electric signal is transferred from the gas valve to the heater, this helps to prompt it to be open. This now helps to pass on the steam of gas. In this state,m of gas passes to the burner where it helps in igniting the pilot.

The temperatures rise and it keeps on continuing until it reaches a point at which the value that the thermostat possesses becomes the same as the room temperature. With the passing of time and the temperature of the premises is again decreasing, the gas valve reopens to give another gas stream to light up the burner to meet the preset value. But the pilot must be kept illuminated throughout the operation, to illuminate the main burner.

This can also be a result of gas wastage. As the pilot must be kept on the running mode it might also be one of the most important and considerable reasons for a clogged gas pipe.

Most common issues with propane heaters and their solutions

The below mentioned things are some of the most common problems that might take place while using a propane heater. If you are looking for solutions you need to understand the problem that is caused first as it is very important.

Standing Pilot Problems

If you want to know that your propane heater has a standing pilot or not then all you need to do is to check.

If your propane heater has a standing pilot it can be easily seen and it is quite visible through a window or opening present under the gas control knob. It is mostly blue and is 1 inch. It is very small in size and it flickers or splits. It also burns yellow or orange. The pilot tube requires cleaning frequently. Normally you would use the gas to turn off and place a needle in the pilot pipeline’s top. It could be because of the drought if the pilot won’t stay lit, but it will always be a thermocouple problem.

Adjusting or replacing the Thermocouple

The thermocouple is the safety measure that helps the propane heater to release the unburned gas. It is a very heat sensitive device that is similar to the one that is present in the thermostat.

When the pilot is lit up the flame tends to heat the thermocouple. When the thermocouple gets very hot it provides a signal to the valve so that it can stay open and the pilot stays lit. The pilot will go out in cases where the thermocouple is very far away from the flames. If you want to fix this then you have to simply push it closer. In cases where the thermocouple wears out then replacing it is a matter where you need to unclip the bulb and unscrew the wire from the gas valve.

Electronic spark issues

If your propane heater is equipped with a blower you might have heard the sound of clicking whenever the blower turns on. This is nothing but the sound that is created by the electronic spark mechanism.

You need to be able to see the spark if you look into the burner chamber. If you do not, the ignitor is likely to be wired to defective electrically. To repair this, you need an electrical device diagram, normally included with the manual of the user. The gas cylinder supplied by the machine can be empty or the gas may be turned off while the heater works without illumination. Clean the opening of the gas valve with a needle if you’re confident that the device has gas.

Thermostat issues

There are chances that the thermostat might be facing some issues in such circumstances the propane heater might not run correctly and it might guzzle up all the gas and deliver a little amount of heat.

The thermostat might have issues and it may not be able to identify the right temperature of the room so that it can properly adjust according to it. By covering the crevices and wedges near boundaries, you can try isolating the space. Make sure you spend some money to recognize and make your premises ‘eco-friendly.’ You will have to change the thermostat in your propane heater if this does not function.

Troubleshooting propane patio heaters

Propane patio heaters are very useful and they are used by many people as they provide a very good service when it comes to outdoor heating. They are very good in small closed places like lawn or terrace.

It is composed in a very simple way with a few components that are connected. The lack of heat is one of the most common challenges you face, which maybe because it’s always held outside. However, if it does not seem to have the way it is used, a quick search with a sequence of steps may be appropriate.

Propane patio hectares might have some problems and issues but unless these problems are something very big or grand they can be easily resolved by yourself with a little knowledge.

Issues with the tank

There are many chances where the gas tank might freeze and it may have issues. If you live in an area where the temperature is very cold or you reside in a cold part of the world then there are chances where the propane gas tank might freeze.

When you notice that the patio heater starts freezing up then you need to check and make sure that the tank is at a level. If this doesn’t solve the issue then you need to get a new tank of propane.

There are possibilities that your tank might have a leak and the tank can also be out of order in situations where the pilot doesn’t light up. The pilot might also be clogged and you can make sure by taking a needle and trying poking the needle into the nozzle of the pilot this will make things clear whether anything is blocking the pathway or not. Before trying this you also need to make sure that the cylinder valve isn’t completely opened or closed.

In case you are attempting to clean the nozzle of the pilot you need to close the valve fully. Once you are done doing this then you need to try lighting up the heater manually. If this manual process works then there might be a problem with the ignition system of your propane heater.

Issues with the flame burner

The flame burner is the most important part of the propane heater as it is the one that helps to generate the maximum amount of heat. This is the most important thing as you look for heat when you buy a propane heater.

If you think that the heat is low then it is an indicator of the gas pressure. You need to check the valve in such cases for gas pressure. If you find that the valves are fine then you need to check whether any other pipes are bent or have any kind of crack or leakage in any way. If you find out that everything is okay then there might be problems with the cylinder and it might be time to buy a new one.

Pilot not lighting up

There might be chances in which the pilot might stop lighting up. This is a very common problem when the gas supply is delivering and it is proper and the electric spark is also working fine still the pilot doesn’t light up.

The biggest reason for such type of issue can be the accumulation of dust inside the heater. This dust is a very common problem that prevents the pilot from lighting or warming the cold room during harsh weather. This simply means that proper cleaning of your propane heater is very essential and you need to clean it to keep the heater lit and if you want to avoid any kind of hassle or problems in the process of lighting.

In case propane gets in your body through inhalation or swallowing you might get affected with propane poisoning the results of which can be dangerous.
