🔥 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
