Furnace Runs 2 Minutes, Then Shuts Off? Check This $10 Hose First

🔧 Everything I learned fixing HVAC for 25 years, in one plain-English book. 📘 THE HVAC SURVIVAL GUIDE - get it here: https://raydutton.com The burners catch, the vents start to warm, and about two minutes later the fire cuts out, then it tries again. The part that shut it down is a small safety switch, so that switch ends up on the invoice at a couple hundred dollars, or the motor next to it at four hundred and up. But the switch is usually just reporting a problem, and the real fix is often a rubber hose that costs about ten dollars. In twenty-five years of these calls, the clock was my quickest clue. In this video I go through the five reasons a furnace quits at two minutes, cheapest first: the cracked rubber hose, the rusted little hole it connects to, the drain that can't drain, the switch itself, and the fan motor that gets replaced when it wasn't the problem. For each one I show you what to look and listen for, what the fix costs, and the exact question to ask before anybody puts in a new switch or a new motor.
