Review on 🔥 Enhance Furnace Performance with Lennox Flame Sensor: The Ultimate Sensor for Reliable Ignition by Edwin White

I needed 20J91 for my Lennox 80MGF oven and bought this by (my) mistake. This one has a longer sensor cable, which is good, but it was pointing down instead of up when installed. I carefully bent the wire 180° and positioned it outside when the flame was on, hoping it would take longer before cleaning was needed. Now it is installed and working perfectly. This is the second cooker replacement in 1993. Next time I won't be in such a hurry and assume I know the number and I'll order the right one ;)
