🔥 Flame rectification is how a boiler proves the flame is lit The PCB sends AC to the electrode ➡️ the flame conducts & rectifies it into a tiny DC current (measured in µA) ✅ A good flame signal is usually 2–5 µA. ⚠️ This one’s only 1.5–2 µA — right on the edge, causing lockouts 👨‍🔧 I advised a full service strip down: burner, sump & electrodes cleaned, then retest #GasEngineer #BoilerBreakdown #HeatingTips #Boilerrepair | Heating & Plumbing Doctors - Coventry

Understanding flame rectification... It starts with an AC signal that is then converted to a DC signal. The flame becomes part of the circuit to help with this process. ***FYI, the lift hadn't moved yet, I was wearing a harness during the work.*** #flamerectification #hvac #flamesignal #hvaceducation #hvacknowledge #hvacsystem #gasfiredheating #hvaclearning #hvacaf #hvactechnician #hvacapprentice | HVAC Know It All

Flame Rectification Ground... The Sealed Unit Parts Co., Inc. TechLink app has a bunch of tests that can be performed with the IDVM550. In this video we perform the Flame Rectification Ground test by pairing the meter to the app, setting the meter to ohms and checking from the burner to neutral. Our reading was 0 ohms which tells us our burner ground is good. #hvac #hvacr #multimeter #ohmmeter #refrigeration #hvaclife #hvaceducation #hvactraining #hvacknowledge #hvacdiagnostics #residentialhvacs

Flame rectification depends on AC polarity relative to ground, so reversing transformer polarity can prevent the control from seeing the flame signal even though a flame is present. #hvac #hvaclife #hvactech
