This is exactly why I watch these videos, learn something new all the time. I had no idea there was such a thing as an 80V igniter. Kind of makes one question why an engineer would even design a weird device in the first place?
Bentley Jarrad this was exactly my question. I'm an electrical engineer, though in a different industry. There's no electrical advantage of using 80V vs. 120V for the igniter. In fact there is a disadvantage in that the board now has to convert 120V down to 80V to drive the igniter. Maybe in days past they thought it would force people to use their proprietary igniters rather than a standard 120V off the shelf version but 3rd party companies can just as easily design an 80V knock off igniter if they want to. Anyway it appears that they've abandoned that ploy. Another interesting question would be, if the board in the furnace on this video had still been good but the igniter had been bad, would Ted have had a replacement 80V igniter!
Nice video Ted. Never actually seen one of these conversions from 80V and haven't run across one yet myself. Everybody always makes fun of me for reading the directions when a manufacturer sends a "kit" of some sort to change the way something works rather than a drop in replacement. But I can see where not reading the directions on THAT kit could really get you into trouble, and the habit has always served me well.
Working for Lennox, I've lost count how many times techs have tried to return these Surelight board kits saying they don't work. Turns out they don't reference the instructions and then they want to argue to about it Thanks for the videos especially this one. Big fan here in Dallas.
That's very similar to my old Lennox furnace. With the help of RUclips videos like this, I've fixed mine 4 times. I've replaced the flame sensor, high temp. cutoff switch, draft inducer, and the board. Easy peasy!
I was lost on the first bunch of wires you pulled Ted. How in the world you remember all those wires is beyond me. Must be the repetition. Enjoyed the video. About that lizard losing its tail. I used to pull them off accidentally when I was a kid out in California. Every time the tail seemed to have a life of its own. It spooked me the first time I saw it.
I just wanted to let you know how much I appreciate your videos. I work as a building maintenance mechanic for an authority that has over 600 units. Our family units (200) have gas furnaces which we are responsible to maintain and servicing. Your videos cover most if not all problems we encounter and are a good resource. I encourage the "new" guys to watch your videos and learn. Thanks for the informative videos, never too old to learn!
The White Rodgers universal furnace control board kit costs more than $100 less than the kit Lennox sells. You just have to use a step drill bit to drill the square hole in the igniter bracket to round to fit the igniter that comes in the kit.
Thanks for the video Ted I have the exact same furnace, just wanted to let you know that you can use the little (smaller) bracket that came with the kit and use the igniter that came with the kit. It fits just like OEM. You just have to use the supplied white wire connectors for the new igniter. Thanks
30 year HVAC Tech/contractor here (GA). Only thing I would have done different is, I would have put the new diagnostic decal on top of the old one on the door. That way there is no guess in which one to go by, and old guys like us can hold the sticker 6 inches from our face so we can read it. lol
What I can assume that thing taped to the side of the furnace where it sits above the return plenum, might be a 'gutter' for when IF the coil freezes or the drain line get's clogged, it won't soak the top of that return box and drips it straight into the pan. If my theory is correct that's honestly pretty smart and can even save some headaches.
Dave Lennox's suspenders were to tight the day he invented the 80 volt igniter system . Word has it he was trying to save power 120-80 = 40 volt savings . GENIUS !
The original installers must have lost their tape measure and snips when they cut the side of the furnace out for the return air. Looks like they had to resort to a can opener!
That's a defense mechanism for the lizard. When they're threatened they're able to drop their tail and it will continue to wiggle to try to draw the attention of the predator while the lizard gets away. The tail will actually regenerate and grow back. #Jimmy
Wonder why the new Lennox board and not a Lennox ignitor from the warehouse? In any regard, all is well...repair went smooth. Would it have been reasonable to replace that blower motor capacitor as well since it was buried behind the circuit board and likely old, just to be sure all is up to snuff for the very small cost? Maybe not.
Nice Video, The Lizard will grow a new tail but the tail will not grow a new Lizard...for sure. Your video reminded me of the John Israels video, I sure Hope they do the right thing and allow John to make right by them...Take care and be safe....
those lizards shed their tails as a defense, the idea is that if the tail keeps squirming like a worm, itll keep the predator busy whilst the lizard escapes.
Not an HVAC tech…just curious but as a homeowner facing a new install, would a metal plenum be something worth requesting from the company or is it really not that big of a deal?
ANTI DIY HVAC,HELLO,YES LENNOX ,does strange things, just like their OWN COMPRESSORS, IN ROOF TOP A/C , ,DOyou know what an OIL RECTIFIER IS dammed CRANKCASE HEATER ! Stay well,good thing you had that board assembly on the truck,, Great going, CHERIO,🇺🇸🇺🇸🇺🇸🇺🇸
My Trane control board died a month before warranty end. Trane sent a new board but it powers the ignitor with 120 instead of the previous 80v. Trane usually sends a new ignitor with the new board but they forgot. The old ignitor therefore fried a week after warranty. Service co ordered a new ignitor but Trane is slow to update their database for my serial number so they sold us an 80v again! It fried in a month. Trane pretends to have a customer complaint dept but they refuse to pay for their mistake. They respond with a boilerplate letter of nonsense. They said they have no control over the quality of locally supplied FREON. I wrote back and said they have my GAS FURNACE complaint mixed up with another customer's AIR CONDITIONING complaint. They replied that they have answered me and therefore have closed the file !! I had to eat the parts and labor costs.
Your problem is 100% with the dealer/repair company. The manufacture is absolutely not the problem in that case. They should have ordered the kit to convert that furnace and not the board. The manufacturer cannot control anything in the field all they can do is manufacture equipment and parts. We are a high volume dealer with a lot of experience. I promise you I am telling you the truth. Thank you for watching!
Ted, a quick question. I’ve never seen you have to do anything when swapping out a board. Mine went on my Trane S9V2 on Thanksgiving. The board was replaced. The installer doesn’t need to program anything on the board? It just knows what to set the blower speeds at automatically? Just plug and play? Maybe because that board is just for the S9V2 series? Thanks Ted
Simple circuit boards like this one don't need any "programing" as the fan speeds are individual wires to different windings on the blower motor for different speeds. Colors tend to be Black (High) Blue-Yellow-Orange (Mids) and Red (Low) that have speed taps on the circuit board. You have a bit more sophisticated board that you have to "program" (select the model type for the correct BTUs and Tonnage) to have the right CFM for that unit. You also probably have a ECM motor that doesn't use speed taps, instead it has a module that pulses the speed for the blower to run.
The blower motor is fixed speed, it has multiple power legs so if you power it on one leg it will be slow and if you power it on an other it will be high.
@@NoeArauz I believe he just swapped the board out. It appears that the blower speed is higher on this board than the original board. Trying to understand if the blower speed on the board needs to be checked and adjusted after installing. Do you go by the fan speed charts in the owners manual? It gives fan speeds vs static pressure. Mine is a variable speed motor. Everything is controlled by the ICB.
The blower speed selection on your S9V2 furnace is made via menu selections using the 2 buttons and the LED display on the board, separate settings for 1st and 2nd stage heat and for cooling. It comes with a default setting, but if you are getting higher fan speeds with the new board, it is likely the default settings were changed on the original board during startup commissioning. It will likely work fine in the heat mode with the default settings, but could way off for the cooling mode. I'd have them check the settings.
This may be random but I've been a residential, light commercial and refrigeration technician for three years. Where I live no techs get paid great just fyi. I've been given an opportunity to change careers and make significantly more money. I love what I do and I've gotten pretty good at it but I wanna make more money. I need advice someone help 😆😂
Oh man,, Lennox and their retrofit kits. I've been down some ugly roads with those retrofit kits through the years though most were fine.. In the early 2000's I had a retrofit kit for one of their VERY early top of the line 80% furnaces that came in a box big enough for 10 circuit boards and a 1/4" thick installation booklet, two fistfuls of wiring , gas valve, ignitor, flame sensor,, new everything .... lol The only things that stayed was the induced draft motor, limit switches, and pressure switch. Long LONG story short it did not work. Actually had the Lennox rep. out there troubleshooting and scratching his head,,, it would NOT stay lit... Neither me or the Lennox guy, , who was good,, could solve it.. AND,,,,,, wait for it,,,,, that was the original symptom !! They got a new furnace..
Hey Ted! Lennox has become a real bad brand, leaky evaporator coils and such, just garbage…lmk your thoughts? Wow a 2000 unit, over 22 year old why not replace it Ted?
It's the customers decision. From what I saw in the video the furnace isn't in bad shape. Keep in mind this unit is from when lennox was still decent equipment
In my experience, a lot of what's wrong in equipment is the technician. More that half the techs out there have sub-par knowledge, typically on installing. Customers have no idea how bad the work was as it generally takes about 2 - 4 years for issues to come up.
This is exactly why I watch these videos, learn something new all the time. I had no idea there was such a thing as an 80V igniter. Kind of makes one question why an engineer would even design a weird device in the first place?
So they can sell you a 120V board and ignitor later.
Follow instructions. Who wants to do that
It’s was cheaper in the past?

Great job on the furnace. You are a genius. The tail moves so the lizard can get away. The tail will grow back for the next time it is threatened.
I love your appreciating for dogs and cats and the like. They really add to the family as well as your videos. Happy New Year.
When I have a service call I always hang out and watch be amazed what you can learn .
I had the same thing done on mine. It was freezing that weekend. Sure am thankful for knowledgeable contractors.

It's not repetition it's knowledge bro..
Knowledge is power..
@@MrG-hm7xs Some repetition is involved. Manufacturers don't differ that much in color coding. Fred is a master at his craft, though.

Uncle Ted working on the dirty six letter "L" word. 😎👍
Lmao
When the lizards get behind defrost control circuit board and get shorted out in Florida, everything works fine. Until the weather gets cold.
Then the heat pump fails to operate in defrost cycle
And sometimes failes to operate in cool mode. Because the condenser fan motor high voltage relay is damaged by lizard
One of my long term goals is to have one of every board on the truck!
Lived in Maine for 5 years in 2 different areas. Never once saw a moose.

Wish I could do that !!
Shannon knight, ďefense mechinism for the lizard? What about when they crawl behind the defrost board on Florida heat pumps?
They did this for tranes too I had to change my grandpa's garage furance circuit board and it went from a 80v to a 120v igniter.
Hello from the guy at Best Buy the other day!
Nice to meet you as well !! Thank you again for watching !!
Always great stuff Ted
That was a mess up on the HSI. I've replaced many and they have the right bracket. Good thing you carry the universal.
Good vid Ted 👍👍👍 Thx for sharing ...
Where is a video of the completed shop
The cat seemed displeased with his car insurance..
Hi Ted, enjoy your videos have been watching for a while now. Quick question, what brand/model multi drive do you use.?
Thanks
The only issue I’ve ever had with my TRANE XR heat pump was that the zone’s were controlling the wrong floors.
looks like a giant steel mouse ate through the cabinet for the return. they needed their lunchtime booze cutoff. lol
only wondered why you didn't "X" out the old instruction stickers, otherwise,good to see,,
Wonder why the new Lennox board and not a Lennox ignitor from the warehouse? In any regard, all is well...repair went smooth. Would it have been reasonable to replace that blower motor capacitor as well since it was buried behind the circuit board and likely old, just to be sure all is up to snuff for the very small cost? Maybe not.
Trane had a 80v hsi in the 90s, they're still out there.
Good yob. I've seen a few flailing lizard tails without the lizard.
Its common for Anole’s to drop their tail when threatened,they usually die within an hour.Nice board job.
Good job Ted.
Cowboy, Isn’t time for a new shop update ???
Agreed. We need to see the new building
Nice Video, The Lizard will grow a new tail but the tail will not grow a new Lizard...for sure. Your video reminded me of the John Israels video, I sure Hope they do the right thing and allow John to make right by them...Take care and be safe....
I have nothing but contempt for lennox. I can never get ahold of Parts Plus after hours and the coils leak terribly.
Hey Ted, you did you reccomend to clean the blower wheel. that one is bad.
Thanks for the video.
i bet the metal track was for wire...idea to keep it clean?
those lizards shed their tails as a defense, the idea is that if the tail keeps squirming like a worm, itll keep the predator busy whilst the lizard escapes.

17:50 My electrical wiring OCD is in hyper-drive right now! 😁🤦♂🤷♂ Must go in there and clean the rats nest of wires! 👍
I couldn't put that much money into a 2000 lennox for my customer. Whats next to break down?
Little Jimmy had a bad day
Why not replace the motor cap while you were in there?
Conversion board in a 22 year old Lennox builders grade furnace. I assume customer didn’t want to upgrade?
I worked on an 80+ last summer 2021 that was originally installed in 1981. It just had some chewed up wires in the outdoor unit.
I thought you would never get those stickers on.
Piece of Lennox
That is the same thing as the WR Universal, just with a Lennox tax.
Did I happen to hear a helicopter around minute 12? ;-)
can i have the old board?
Could u show detail to condemn a board
He must be an engineer.

14:07 "The neutrals in the neutral zone" Is Ted a Star Trek fan?
No not as much now as I was when I was a kid.
Did you use your jimmy wiggler?
This must be a east coast thing I never seen a 80 vote igniter in my 25 years as a tech

Sorry if I missed it, but was the blade fuse bad on the board?
Board was burnt up. We didn't learn why that happened.
That copper gas line is no longer allowed and should be removed, they corrode way to fast...
this will go smooth as clockwork? how about silk lol
Ted was just anxious to 'make like a tree and - get out of here'. lol 🤦♂
I swapped one from Trane and I got a new igniter with it. Explanation was that it was 90v.

At least a moose would stay outside.. I've never encountered a lizard in my house, nor do I ever want to.

Always put the fault code sticker on the front of the blower door not buried in blower compartment . Lennox wiring diagrams are useless!
Before I even watch, it's a neutral problem , let's see.
Video quality isn’t that great
