A pilot light is one of the key elements that help a heater to ignite without human interference. Common Gas heaters that warm up the air in our home rely on a pilot light for triggering the flame of the actual heater. If the pilot light ever goes out, the heater will not turn on to heat the air. These heaters circulate the warm air in the house. Knowing the maintenance procedure of the heater and troubleshooting the regular pilot lights issues will help you avoid costly Gas Heating Repairs in Adelaide. It’s not very tough as everything looks tough unless you don’t try one – two times on your own.

If the Pilot light doesn’t stay lit, it becomes more than frustrating. This situation not only prevents the furnace from operating properly, but an unlit pilot steals the comforts of a hot morning shower too apart from calling a reliable professional for Gas Heating Repairs in Adelaide. Unfortunately, there are a variety of reasons for pilot lights going out; all of them are dependent on some factors. However, understanding these reasons goes a long way in preventing future pilot light outages and eventually saves your money on Gas Heating Repairs in Adelaide. Following are six potential reasons why the pilot light may go out and how to fix it.

Obstructed Thermocouple – Almost all water heaters operate with a thermocouple. This device is the critical factor in the operation of the heater and can detect if the pilot light is on or off by an electrical current powered by the pilot’s heat. As soon as the thermocouple detects an unlit pilot, it turns off the gas. This is an inbuilt safety precaution. If the thermocouple is left dirty, then the electric current received from the pilot may be obstructed, leading to gas outages. For fixing this, Gas Heating Repairs in Adelaide can be performed on your own. You should simply locate the thermocouple & clean it with the help of sandpaper. Before you start cleaning, ensure that the gas is off, and the thermocouple is cool to the touch.

Curved Thermocouple – Apart from compacted dirt and grime, a thermocouple can get bent to the point where it is no longer operational. If the thermocouple is far away from the pilot, then it won’t be able to convey the heat. After following the safety precautions, simply bend the thermocouple back to its original position without the need for Gas Heating Repairs in Adelaide. Just ensure it is close to the flame of the pilot light. Typically, the flame should touch the thermocouple or be close enough to heat the device. A good thumb rule is to look at the light and make sure that it is wrapping around the sensor. Furthermore, a healthy pilot light appears blue.

Damaged Thermocouple – If you are certain that the thermocouple is the main cause of the problem, and there aren’t any signs of dirt or bending, then it might be possible that the device is simply broken. To prevent this, you might need to replace the device or have it proper Gas Heating Repairs in Adelaide. Again, before doing anything, ensure the gas is turned off, and the thermocouple is cool too. Once this is done, simply take out the furnace cover & unscrew the thermocouple. Alternatively, you can determine if the thermocouple is bad by using a multimeter for testing the voltage coming from the thermocouple. Readings below 20 MV indicates a terrible thermocouple.

Filthy Pilot Tube – If the thermocouple shuts out, then another possible culprit might be a filthy pilot tube. Dirt and grime build up and blocks proper flow of the fuel gas. Luckily, fixing this is very easy, and a straightforward process and you don’t know ned for an expert in Gas Heating Repairs in Adelaide. After turning the gas off and waiting for a few minutes for the pilot light to cool, simply take a needle and clean the tube. You will prefer to take out anything large that might be blocking a clear path. After proper cleaning, turn on everything and see if the pilot lights itself again. If it fails to light, then simply repeat the process until everything is thoroughly cleaned, or call for an expert in Gas heating servicing Adelaide.

Flex Tube Issues – Another possible reason for a pilot light that won’t stay lit has to do with the flex tubing. This tubing connects to the gas controller and ensures a steady stream of gas. Sometimes, this tubing gets kinked in places which prevent proper operation. If this is the issue, then unkinking the flex tube might resolve the issue. If it doesn’t work, then new tubing will be needed to be installed. This occurrence of this problem is less frequent than thermocouple issues and should be checked after the thermocouple has been ruled out.

Main Control Valve – In rare cases, issues with the main control valve causes a pilot light to go out. Main control valves do not go out, and we should check for all other possibilities before Gas Heating Repairs in Adelaide your own. If the main control valve is faulty, then it will need to be replaced to fix the problem. If you are uncertain about whether or not the main control valve is operational, then you should test the thermocouple with a multimeter to properly rule it out as the main culprit.

Vacuum Occasionally – Although the accumulation of dust in your heating unit doesn’t necessarily create a safety issue, it’s still beneficial to occasionally vacuum your heaters for removing the accumulated dust and debris. A wall heater does have a burned dust odour when they are first turned on after infrequent use. Vacuum cleaning helps eliminate this odour issue. If you know that your heater will only be used rarely, consider investing in a cover for it as another means of keeping dust and debris out. This will not only give your heater a long life but minims your expense on Gas Heating Repairs in Adelaide.
