🔥 Enhance Furnace Performance with Lennox Flame Sensor: The Ultimate Sensor for Reliable Ignition Review

OEM replacement for the original flame sensor in my Lennox oven. The price was great. Very fast delivery. Fits perfectly.

This worked great and saved me a ton of money since I did this "repair" myself. Very easy to install and there are videos on youtube if you get stuck

Although slightly different in size from the original, this flame detector has been mounted upright and in the correct position for flame detection. The heater caught fire and above all did not stop!

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
