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?

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.

The cat was working just as hard as you were Ted

That's very similar to my old Lennox furnace. With the help of KZfaq 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 had the same thing done on mine. It was freezing that weekend. Sure am thankful for knowledgeable contractors.

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.

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.

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.

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!

When I have a service call I always hang out and watch be amazed what you can learn .

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.

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.

Lived in Maine for 5 years in 2 different areas. Never once saw a moose.

Nice trick with the cool wire to bypass the board def will use that in the future 👍

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

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!

I don’t see many Lennox systems. Great info. Thanks

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

Where is a video of the completed shop

One of my long term goals is to have one of every board on the truck!

That was a mess up on the HSI. I've replaced many and they have the right bracket. Good thing you carry the universal.

Uncle Ted working on the dirty six letter "L" word. 😎👍

The cat seemed displeased with his car insurance..

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.

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 only issue I’ve ever had with my TRANE XR heat pump was that the zone’s were controlling the wrong floors.

Always great stuff Ted

only wondered why you didn't "X" out the old instruction stickers, otherwise,good to see,,

Good vid Ted 👍👍👍 Thx for sharing ...

Hello from the guy at Best Buy the other day!

looks like a giant steel mouse ate through the cabinet for the return. they needed their lunchtime booze cutoff. lol

Good yob. I've seen a few flailing lizard tails without the lizard.

Trane had a 80v hsi in the 90s, they're still out there.

Its common for Anole’s to drop their tail when threatened,they usually die within an hour.Nice board job.

Good job Ted.

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.

Cowboy, Isn’t time for a new shop update ???

Hi Ted, enjoy your videos have been watching for a while now. Quick question, what brand/model multi drive do you use.? Thanks

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?

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....

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?

Little Jimmy had a bad day

can i have the old board?

Why not replace the motor cap while you were in there?

I thought you would never get those stickers on.

Could u show detail to condemn a board

He must be an engineer.

I couldn't put that much money into a 2000 lennox for my customer. Whats next to break down?

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,🇺🇸🇺🇸🇺🇸🇺🇸

Conversion board in a 22 year old Lennox builders grade furnace. I assume customer didn’t want to upgrade?

Did you use your jimmy wiggler?

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.

Did I happen to hear a helicopter around minute 12? ;-)

That is the same thing as the WR Universal, just with a Lennox tax.

17:50 My electrical wiring OCD is in hyper-drive right now! 😁🤦‍♂🤷‍♂ Must go in there and clean the rats nest of wires! 👍

Piece of Lennox

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.

How long have you been in the trade?

This must be a east coast thing I never seen a 80 vote igniter in my 25 years as a tech

Greetings from Australia !!

He just unplugs all those wires! How can he remember where they go?

Clint Eastwood 😃

When I get a helicopter, I give em an endless task

this will go smooth as clockwork? how about silk lol

14:07 "The neutrals in the neutral zone" Is Ted a Star Trek fan?

Sorry if I missed it, but was the blade fuse bad on the board?

👍

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

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 😆😂

17:37 How about using Wago connectors instead of wirenuts?

I swapped one from Trane and I got a new igniter with it. Explanation was that it was 90v.

That copper gas line is no longer allowed and should be removed, they corrode way to fast...

Duct board is all you see where I’m from or flex.

The 1/4 inch copper easily slips into your meter case and it will always will be there no excuse

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..

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

Hey Ted - have you blocked my comments ??

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?

id much rather have moose than lizards

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
