🔥 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

We are well into the heating season! This furnace has caused a few headaches this year. I do very little residential but I always try to take care of this gentleman. There will be a point that the furnace will need changed, but I give him the parts at cost and the labor really cheap due to his circumstances. It's always fun to see something slightly different and the way this flame sensor mounted was definitely the first time I've seen that style. I will probably need to make a future video bett

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
