Good job. Your videos are high quality - good lighting, sound, and resolution.

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

[@deanmartin1966]

Ditto. Very thorough.

[@melvinwillingham233]

Your meter leads are crossed. Common lead to the sensor

[@hvactechwanttobe1499]

That was a tuff one you the man

[@MrRikkitikki]

No pressure switch code?

[@Scott-hb8pu]

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

[@sunshinel5975]

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

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???

[@erik1514]

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.

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. 😎👍

Good find on the loosey goosey wire.

I had a gas valve that had me going back 4 times .....never showed it's dirty face the first 3 visits....

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.
