How To Wire Double Float Switches

HOW TO SERIES!!!! In today’s video, I’m showing you how not to wire condensate safety float switches—and more importantly, the correct way to wire them so they actually do their job. This home has two condensate safety float switches, and I see this wiring mistake far too often. When float switches are wired incorrectly, they won’t shut the system down when water backs up, which can lead to serious water damage, mold, and costly repairs. 🔧 What we cover in this video: • What condensate safety float switches do • A common wiring mistake that makes them useless • Why wiring float switches in parallel is wrong • How to wire multiple float switches in series • Why cutting 24V power to the thermostat (R wire) is the best method • How to properly test float switches after installation By wiring the float switches in series, if either switch trips due to water, the entire system shuts down—exactly how it should. This provides real protection instead of a false sense of security. 🙏 A quick word of encouragement: Just like safety float switches protect a system from disaster, we all need a safety net in life. Psalm 46:1 reminds us that God is our refuge and strength in times of trouble. True safety comes from trusting the One who sees everything before it happens. Thanks for watching. Bless you, and I’ll see you next Friday. #HVAC #HVACTips #HVACTechnician #CondensateDrain #FloatSwitch #SafetyFloatSwitch #HVACTraining #HVACLife #HVACR #ACRepair #AirConditioning #TradeSkills #SkilledTrades #HomeMaintenance #HVACEducation #TechTips #Wiring #ElectricalHVAC #PreventWaterDamage #HVACInstall #FaithAndWork #Psalm46 #TrustGod #ACandLife
