How to Test Pressure Switch on a Furnace

How to Test Pressure Switch on a Furnace. In this video I show 3 ways how to check a pressure switch. The first method is to measure continuity and resistance while the furnace is running. The second method is to check voltage on the pressure switch while the furnace is running, and the third method is to put a manometer in series with the pressure switch to see what vacuum pressure the inducer motor is pulling and if it matches/exceeds the rating of the pressure switch. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ➡️ Video Reference: 10 Reasons Why Pressure Switch Wont Close: https://youtu.be/Zax02itYHkU ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ For More Repair Videos: 🔌 Dryer Repair Playlist: https://www.youtube.com/playlist?list=PLK8tZPlovA8DyWVUXZFEdP1GN6sYOu5CP 🧺 Washer Repair Playlist: https://www.youtube.com/playlist?list=PLK8tZPlovA8DZ_JCHVUX2jIfqU_F3BEDS 🔥 Furnace Repair Playlist: https://www.youtube.com/playlist?list=PLK8tZPlovA8BJJ_weFseSjQWUvB2FFII2 ❄️ AC Repair Playlist: https://www.youtube.com/playlist?list=PLK8tZPlovA8Aw5W4GIoingc_enl5apH4C 💧 Water Heater Playlist: https://www.youtube.com/playlist?list=PLK8tZPlovA8AJXKuLPbaG6uPbG28wRD6L 🛠️ HVAC Tools Playlist: https://www.youtube.com/playlist?list=PLK8tZPlovA8Cn_Jh-HkdIRAJ4fzweqmAP 🔋 Capacitor Playlist: https://www.youtube.com/playlist?list=PLK8tZPlovA8A-Q4k613Siy1v6lr0Jim3d ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 🛒 Furnace Parts Reference: Furnace Filters 6 Pack: https://amzn.to/2SyXT6F FM55 Motor Bracket: https://amzn.to/2RrcZKh 409 Hot Surface Ignitor: https://amzn.to/2DdKXiq 402 Hot Surface Ignitor: https://amzn.to/2Q69tVp Universal Nitride Ignitor Kit: https://amzn.to/2CS5msj Universal Nitride Ignitor: https://amzn.to/2Ddn2zv Flame Sensor: https://amzn.to/2Js4POT 1/4 HP Blower Motor: https://amzn.to/2yGiUnM 1/3 HP Blower Motor: https://amzn.to/2SygVKH 1/2 HP Blower Motor: https://amzn.to/2RsBdUB 3/4 HP Blower Motor: https://amzn.to/2Q6auNd 5 uF Oval Capacitor: https://amzn.to/2Rt1LoF 7.5 uF Oval Capacitor: https://amzn.to/2Q7YkTU 10 uF Oval Capacitor: https://amzn.to/2SwMXGT 15 uF Oval Capacitor: https://amzn.to/2JsAdgk Carrier 80% Inducer Motor Kit: https://amzn.to/2Q8cdBE Carrier 90% Inducer Motor Assembly: https://amzn.to/2RoeCZi Goodman 80% Inducer Motor: https://amzn.to/2JtWMRy Goodman 90% Inducer Motor: https://amzn.to/2Q8nd1Z Trane 80% Inducer Motor: https://amzn.to/2SyH4Jo Trane 90% Inducer Motor: https://amzn.to/2Q6b8u7 3" Hi-Limit Switch: https://amzn.to/2Svmg5j Small Hi-Limit Switch: https://amzn.to/2Q2vtjU Honeywell Gas Valve: https://amzn.to/2yGvB20 Round Digital Non-Programmable Thermostat: https://amzn.to/2JsIsc2 Basic Honeywell Programmable Thermostat: https://amzn.to/2JqEjFy Nest Thermostat: https://amzn.to/2qlCgds ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 🛒 For a Complete List of Tools and Parts Visit my Amazon Page: https://amzn.to/2Q3QTOA ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 🅿️ If you want to support the channel: paypal.me/WordofAdviceTV ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 📷 Interested in What Gear I use to Film my Videos?
