Testing A Thermistor | What Should The Readings Be ? | Gas Training | Plumber

Hey there fellow plumbers and DIY enthusiasts! Today, I want to chat about something that every plumber should know about – testing a thermistor. Whether you’re a seasoned pro or a homeowner trying to tackle some heating issues, understanding thermistors can make a world of difference in your plumbing and heating projects. So, what exactly is a thermistor? In simple terms, a thermistor is a temperature-sensing resistor that helps regulate the temperature in your heating systems. Think of it as the little gadget that tells your boiler when to turn on and off. If you’ve been experiencing erratic heating or boiler issues, it might just be time to check that thermistor. In the video, I go through step-by-step how to test a thermistor, including what readings you should expect. It’s crucial to know these numbers so you can determine if the thermistor is functioning correctly or if it needs replacing. For most thermistors, you should see a resistance reading that correlates to the temperature they’re sensing. If you’re getting wildly inaccurate readings, it’s likely time to swap it out. As plumbing pros, we know that a simple troubleshooting step like checking a thermistor can save us and our clients a lot of headaches down the line. So, whether you’re a homeowner tinkering with your boiler or a professional plumber looking to hone your skills, I encourage you to check out the video and learn how to test a thermistor yourself. By keeping these valves and sensors in check, you’ll ensure your heating system runs smoothly and efficiently. Happy plumbing!
