Thank you for sharing.

Concord

I thought black is supposed to be on L2 but mine came from factory 3 wire with 1 hot lead on common and black hot on L2

THANK YOU FOR THIS!!! My Ducane furnace is in my attic, installed horizontally, I didn't even think about laying down and looking up to find the data plate LOL

If you install the 19V36 board in a furnace that is dual-speed heat, the furnace will then be single-speed heat as the 19V36 board doesn’t support dual speed. Also, if the 19V36 install guide tells you to put the red “ACB LOW” wire on the “CONT” terminal of the 19V36 board - don’t do it. If you do this, your blower will run on low speed 7/24 continuously even when the thermostat is off. Instead, move that wire to one of the 19V36 board PARK terminals. The ACB LOW red wire is the low speed blower wire, and there is no low speed function after installing the 19V36 board, so the correct terminal for it on the 19V36 board is one of the PARK terminals. A PARK terminal is not connected to anything - it’s just a place to put an unused wire.

Thank you!! You time making this was well spent

Take pics multiple if needed!! It was all easy till pins came out of old board and I lost my taught! But overall very easy!

Awesome, thank you so much.

thank you

Was searching for an hour here on a single run capacitor if there was a polarity difference. Looking at the other comments I wasn't alone! Thank you for helping us out!

Thanks so much. Needing to register my units and wanted to see where to locate the S/N before I went into the attic. Great explanations.

Thank You for addressing the polarity question.

Great job. what a detail explanation about the part number. It is very helpful. Thanks.

I have a question please… I like your video, but My new control module board is like this one that you are showing in the video. The old board that I have has a neutral wire going next to the spark wire that is not shown on your old board. Do I simply omit this or is there a place on the new board to connect this to?

Thanks, bud.

You're a lifesaver -- thanks so much, this was so well-explained! Working on mine now :)

Mine is a three wire and the original came with a black a purple and a brown. the new one come with a black a white and to browns. I understand that the brown with the white stripe is not needed so does the white wire act as the purple?

Excellent video as a guide. Definitely feel confident and able to fix issue. Thank you

where do you plug the white? Its a nuetral, but where does it go?

I've replaced two boards in a 2-1/2-3yr period so far. Board wouldn't let me clear the code. Also, it would never go in soft lockout mode. That's when I figured it was the board. Who's making these boards for Lennox?

so the thermostat is powerd by 12v DC current batterys and it sends the signal to the 12v DC current coil on the contactor so than the contacts close and send 120v to start the compressor and fan¿¿ am I correct??

¿What is the reason that the outer material is metallic instead of a dielectric insulator? Is it to dissipate heat?

The board you installed doesn’t look like it is a 19V36. It looks like a 83M00. Your title says both? Your video is excellent.

Great video was curious i have Module BGB891-2 -Y4749 that is bad, will this model your showing work on my Lennox Pulse 21 , and if so where are the instructions, listed on your website, didnt see them , thks

Is this style of contactor orientation sensitive?...meaning.....as long as you're mindful of "L" connections used for power-in....and "T" connections for power-out....can the unit be mounted either right-side up or upside down? ( printed material on the cover is then upside down?).....I think it doesn't matter, but thought to ask.

Thank you so much!

Hello I found that my coil pigtail from the thermostat to the contractor is loose and wobble and make a humming sound. My AC air is not that cold anymore. Do you think replace can solve the issue?

Where is the common wire location??

unit looks in great shape for 1998

I'm happy I found your video. I'm trying to register my Air Quest Air conditioner and I'm having a struggle going through my receipts and docs to find the Model number and the Serial number. Now I know! I will go outside and look for the sticker with those info on the air hanger.

No polarity. THANK YOU!

Got a question..

Thanks so much great video, even 8 years after you produced the video !!

So helpful, thank you!

Good work, it’s nice to know this works for units with Robertshaw and Johnson controls boards.

What a fantastic video. I'd hug that man if he was near me.! Thank you very much! The instructions that came with board... garbage. The only thing different from mine and his... My yellow and green wire were in the board together. I cut the green (ground ) from yellow and attached it to the ground. My board also came with a brown thicker wire labeled ACC on the board. That must be for a multi speed fan blower. I followed the brown wire to its origin and a 3 connector (black white brown) plugs into a 2connector. (Black white) Brown empty. Once again.. fantastic video THANK YOU !

I just installed this part. Problem that the connector to the spark wire was brittle and broke when I followed your video to cramp. I am thinking depending on where you get part the connector may be brittle or not. Maybe mention in video.

Very good video

Thank you. I needed this.

could of been better.

when contacts are new, they have a uniform of what ?copper?

I have a question on L1 same side i have 240 all the way to the other side is the normal?without the switch being pull in (my heater dosen't work )

On this type of furnace, why would the ignitor stay on, sparking continuously even when furnace not running. Only way it will shut off is when you disconnect power to furnace

Thanks, got my Lennox Pule 21 working with this video.

Great job.. ty it help alot

Thank you great explanation

thank you sir

What control do I replace the johnson control proven pilot control G60 PFL-1

This guy is excellent tech 👏.

My coils C1395-6(16115 ) I need to know what it goes to
