System Not Staying Lit. Flame Sensor Problem? Nope! EP81
Тәжірибелік нұсқаулар және стиль
I was sent out to complete a repair for another tech. He told me the flame sensor needed to be an OEM part, so I was sent out to swap it out. Of course it didn't work and I was left to figure it out. After some testing and conversation with Lennox Tech Support I found the actual problem. Here what happened.

Great find👍
I could’ve just totally missed this until now, but you put your meter lead connections and extended them with the alligator clip leads?!? I’m stealing this immediately
Good job. Your videos are high quality - good lighting, sound, and resolution.
That was a tuff one you the man
So it gave a flame sensor code on the board? That was a good video. Thanks for the explanation. I always learn something when I watch ur videos
I knew right away it was the pressure switch. I had this exact issue where it would run for random amount of times before it shut down. I replaced the pressure switch and it resolved the issue.
Nice job and great knowledge. Thanks for sharing your experience
Your a good tech.. I have been a tech for 30+ years and owned my commercial hvacr business 20 yr I would hire you... this is a hard business...like your video

Ditto. Very thorough.
Nice job
Excellent diagnosis… I learned another connection to focus on quickly when faced with this intermittent issue. Thank you! BTW… is that flex vent pipe up to code in your area? Just curious.
No pressure switch code?
My furnace runs with the burners for 4-9 minutes and then shuts off the burners. I do not get any error codes. It just goes into idle mode. It takes a 15 minute break and then does the same thing. This only heats the house up by .5 to 2 degrees at a time, so the furnace never catches up. The furnace filter was completely clogged. I replaced the filter, the thermostat, cleaned the flame sensor rod and sparker. Still the same problem. What could it be???
Maybe it’s high limit switch
7 uA is high for a flame sensor. 2's & 3's are most common. Even high 1's will usually keep it going. 😎👍
