Gas Training - How To Test Air Pressure Switches In Gas Boilers - Fault Finding

Gas boilers are a crucial part of many homes, especially during those chilly months. Understanding how they work, particularly the air pressure switches, can save you time, money, and a lot of headaches. Today, I'm sharing some insights from my recent training session where I learned how to test air pressure switches in gas boilers. First up, what is an air pressure switch? Simply put, it's a safety device that ensures your boiler shuts down if the air intake isn't functioning properly. If this switch is tripped, it can stop your boiler from working, and that's where the hassle begins. Testing these switches is a vital skill, whether you're a professional plumber or a DIY enthusiast wanting to keep your heating system in check. In the video linked above, I delve into the step-by-step process for troubleshooting and testing these switches effectively. To get started, make sure you have a multimeter handy. This tool will help you measure voltage and resistance, which are essential for diagnosing any issues with the switch. The trick is to understand the readings — if the switch isn't closing properly, it's likely faulty. Don't forget the safety precautions when working with gas appliances. Always ensure the boiler is off and cooled down before you start fiddling with components. If you’re not comfortable testing the switch yourself, there’s no shame in calling a qualified plumber. Lastly, take a look at the video for a more in-depth look at the process. Whether you’re a seasoned pro or just starting out, there’s always something new to learn in the world of plumbing. Happy troubleshooting!
