Good job Billy. All boards produce a constant AC voltage output to the flame sensor. You can check the AC voltage from the flame sense terminal on the board to ground to see if its within range for the particular board. Thanks for the video.
That might have been tracking. Where a carbon track builds up over time between two PCB tracks with a high voltage across them. In this case possible the thyristor that fires the ignition transformer. I find it a good idea to take a clear photo of a board before I swap it.
Pierre Ruff I always keep a soldering iron (with pig tails) and solder in my bag just invade maybe the board can be repaired, saving me an extra trip back and having the customer wait even longer
One thing I learn about Lennox they still use old school relays for their equipment and I find their wiring diagrams a little tricky sometimes other than that Lennox makes good stuff. Good video billy
was working on the exact same unit today, went through the same process as yourself, changed flame sensor, still 0 micro amps at sensor. will be checking out that board closer tomorrow
Good video...I'm having a problem with a York RTU, erratic burner ignition...Honeywell S8610u module...Pilot tube was blocked up pretty bad, cleaned it, cleaned flame rod, cleaned spark igniter, good for three days and going back this AM....I didn't have a meter that was capable of checking the flame rod, I know,.........No excuses, just forgot the damn thing after using it in my home....I'll be doing that and thinking maybe the draft inducer circuit might be faulty or erratic if not the flame sensor....Maybe a bad grd. on the burner circuit...I'll let you know....Thanks for this video...I hate call backs, especially in winter, know they happen in this trade, but Damn it to hell...lol
First Off Great Videos , just Subscribed ... New in the Field .. I have 21 RTU units to maintain Goodman 15 ton 10 ton. Overwhelming as far as maintenance, up there everyday. Great warranty tho, they replace parts. Except I still have to Labor. Gone thru 5 Compressors this Summer / Blower Motors / Condenser Fan Motors. Constantly one problem after another. Today's mystery - (3) Units Never Shut off no matter what I do "pull the thermostat off the wall" still running. Thought it was the Fan Relay -tested- somethings back feeding my Green Fan Wire - possibly circlet board ?
I feel like an idiot...I worked on a York RTU unit that visually, showed no signs of a cracked heat exchanger, but it was...It had to warm up first and then the crack would appear, at a seam.....When cooled down, it would close....No blow back or flame flutter at all, and it had to get hot, before the crack appeared, and even then, it would not always appear...When it did, it shut the unit down on the hi limit, then cooled back down and showed no crack again...Reset limit never tripped...No carbon build up on exchanger, nothing....Finally, at night, it showed....A nightmare, literally...I dreamed about it and some how in my dream, it came to me....Look at it at night....Bingo....I was mad at myself and glad at myself at the same time...Thanks again for making this video.
hi BK videos and i got a question in how do you handle with your customers like when you have to make like 2 or more trips to the supply house because some of them may think and look at you like does this guy knows what hes doing or hes just guessing if you know what i mean'¿ some of them do not understand troubleshooting sometimes is not that easy!! happy holidays..
this was a commercial customer....so I don't even check in with the property manager untill I'm done...so no problem here... but for residential customers...they are told that this is the part that is bad...but there may be other problems after I get this one in...and I will not know until I get this in and powered up... I explain I can't have everything for every unit in my little van... and I have had no problems yet..and I've been here at the same company for 19 years....
Excellent video

Thanks for the info +paokoma.

Great work & find Billy!!!
Thanks man!
Fantastic stuff Billy, you're doing a great job with the videos!
Thanks Stephen Rardon . I appreciate it.
Control boards alway make u go crazy. I alway look at the of them for burnt marks. Great job.
Thanks man... I try to look all the time... But this one was killing me..Thanks for watching...

Billy, I don't go wire for wire because I like to smoke on occasion. Good job my man!
Lol Larry.... Thanks man.. Thanks for watching
Larry Cole you just living on the edge
T&N Services LLC. Lol...that's what I was thinking...

good fix Billy. wire for wire is the way to go....
Thanks man...easier that way

Good fix Billy
thanks man...
Where can I buy this part at for model "GCS20H"?
Nice find Billy
Thanks Ralph!!!
Having this same issue right now but even with new board, not resolved.
Are the front of the burners clean?
Near new unit 1st time in heat
But yes
Good video, nice job on the fix
Thanks man
Ahhh, yes. The good old days.
Have the exact unit and the exact problem. fan goes on but no heat. No pilot on. How do you put the pilot on with these units?
Good job Billy but could they have mounted that pressure switch any further away from the inducer motor lol.
Thanks justin!!! I know that switch is so damn far... I dont understand why???
In this case you might say the flame was sensed (by the sensor) but the board just didn't give a damn. lol Good video.
I agree with that 100%
Great job Billy
Thanks harry
Name of song an nice work
wow

Great find
good work
a tleast the leads are long enough swap easly one by one
Just another day on a roof....
Nice find Billy Knoth
Good work man👍
Thanks Tazzman228
Thanks Rob HVAC
That's a great video, thanks for the name in the credits.
nice fix Billy Knoth
Thanks man!
Little bit of resolder and you could've had that job done way sooner and not had to go back twice. Just saying. Stay safe and keep up the good work
Please make more VIDEOS
