I watched this video and one other 4 years ago just because it was there. Walked out to my pool equipment today and could smell burnt wire..Readout says low cell voltage. I had it apart in 5 minutes and repaired another 5 and back together in 5 more. Thanks to you and one other site. Checked today and a new pro logic mother board is $990. not including labor. I did order a new relay switch which is the item that overheats and burns up the connection pin and melts the board. $11 for that relay and will change it one day when it gets cold out. Thanks again.

I was extremely skeptical but in less than 20 minutes I was back in business. The board smelled from the burnt connection but I heated up the ol' soldering gun and applies a generous portion of solder. I just loosed the two nuts, lifted the board, tilted it forward to a laid down position and soldered it in place. both circuit breakers off inside the box. Thanks so much!!! Working perfectly!!!

Was trouble shooting and came across this video. I had called my pool guy and he said most likely needs a new board but also said he’s not a computer guy so he called a tech who said 98% chance it needs a new board. Figured I had nothing to lose so I pulled board out myself and had the connection soldered at a local stereo shop for $20 and I’ll be damned it fixed it. After seeing all the inquiries this should be a recall in my eyes. Just my ex two cents worth maybe one…

Amazing. My unit looked exactly like this. Borrowed a soldering iron from my Father-in-law. Sanded the contact to get rid of the oxidization. Heated it - touched the solder. Let it cool for a minute. Put everything back together and powered everything back up. I did it where it hung all connected but no power. Worked like a charge. Best feeling to see everything working and no "Service" light. Perfect tutorial. Thanks so much !

Great Video!! I called a pool guy who had no clue on how to possibly save the circuit board. A waste of $95. I did the soldering and it worked. Thanks for saving me a sh*t load of money.

Bought a solder gun for $15 and followed the instructions. It did not work immediately but the service light was gone overnight. Works like a charm now. Thanks

Forget the little insurance lizard...in 15 minutes, you saved me $500 bucks!! Thanks!!

Just fixed mine. Saved 850.00 for a new one. Thanks a million. If you do it just make sure you practice soldering on something else first and clean the connection with alcohol and toothbrush after you de-solder it. Makes a world of difference. Use flux. Do it right and it will work.

Thank you, worked as described and cost ...zero. Pool repair quoted us $650 for a new board or $250 to fix ,but no warranty. So relieved. thank you a million times.

Thank you, you saved me $590. I followed exactly what you did completed it within 20 minutes and did it all with a $10 Soldering Iron I purchased at Walmart! Appreciate your post.

June 3, 2016 I just followed this procedure and it worked. I had been flipping breakers for an in home remodel and blew the logic board on my garage door opener as well as this issue with the pool logic board. Anyway I followed this guys video exactly and had no problems. Thanks!!!

Wow I figured what would be the worst case scenario due to the location of the soder material... I wasn't going to touch any additional circuitry and all power was off . I borrowed a soldering iron from my neighbor who also had the proper soder materials which were designed for electronics , I gave it 4 tests for heat and the perfect puddle, and less than 10 minutes later I was up and running and I could see the amps and the salt system gaining momentum . You saved me big bucks...I I can't than you enough! Can I send booze or flowers lol

I just used your solution to fix the exact same problem. It worked flawlessly and saved me a lot of money and frustration! Thank you very much for the tip!!

Same here! Thanks for the video. Literally a 15 minute fix from start to finish and until I came across this video I had NO idea what was wrong or where to start. I love youtube.

We just fixed mine and want to thank you for making this video the soldering did the trick and luckily we have a family friend who is an engineer and he did the soldering, replaced the fuses and has fixed some others issues. We live in a rural area by Yosemite National Park and it is not easy to find service folks for pools.

I had a brand new motherboard ready to do a quick swap today. When I flipped the current motherboard over and saw a burnt spot, I decided to desolder and resolder one of the K1 legs as you suggested here. 10 minutes later, bam! Power was generated to the T-Cell with readings, and the error ... gone!!!! Had to comment to thank you for saving me $$$.

Sadly the link to the page is no longer active, but this video did the trick! Thank you for posting it!

Right on and thanks again. Had the same issue again and forgot about this video. I invoked your repair previously, doing a similar soldering job (haha!) - and fixed it. Just looked at it again, chipped away carefully some of the old solder, re-did it and fixed it again. Wish there was a permanent solution. But dude - thank you for taking the time do document this. Restores my faith in humanity! :)

This worked perfect with my Hayward Pro Logic GLX-PCB-PRO board. Same burned out contact exactly. Soldered and repaired in minutes! Thank you!

This worked perfectly. I did pull the whole board off to do the solder at my work bench.I just took a pic of the wiring. Easy peasy. Thanks for posting.

Thank you so much! My aqua cell has been out of commission for three years. My husband found your video, I must admit I was quite the skeptic... Amazing fix ... Thanks

Worked like a champ! I also add a jumper wire from the bad solder point to an adjacent solder point that had continuity prior to jumper. I read that on another thread. Beer and steaks tonight. Merica!

Thank you! I you made it look so easy that I decided to take a swing at it. A few minutes later (and after a trip to buy a soldering iron) the cell is back in action :)

Drew, I know your post is old, but it still works, oh and your soldering job is far superior to mine, but it works. Thanks

Thanks for sharing this, I just had the same problem soldered the K1, it took three tries but I finally got it fixed and is working fine now. Presidential pools said I would have to spend $550 to get this replaced. Thanks for paying it forward, I will be sure to do the same.

Glad to hear this is still working for so many folks!

This happened to me a couple of years ago. I tried twice to solder (or should I say "glob" of solder) it myself and it would work for a month or so and then turn off. I was so happy when it worked though. So more google searching and learning a bit more about soldering I realized you need to know a bit more before patching this up. So I looked up soldering people in my area and lucked out. Found a person who teaches soldering and for $50.00 and a beer he came by with his whole kit and professionally cleaned the area and put the proper solder for this type of system (to withstand the high heat...). I hope I don't jinx myself but two summers went by and no issue. Terrible for Goldline to create such a problem and make unsuspecting people replace their unit. Should be a recall!

Just worked for me!!! Solder joint was bad, re-soldered and error light is now off, "No Cell Power" alert is gone, and all seems well. Thank you very much!

You are the Man. Had this exact problem and your Video had me up and running in about 10 minutes. Thanks so much!

Thanks a million, worked like a charm for a simple $24 for a soldering iron 👍

Thank you! Perfect diagnosis and repair details-Saved my motherboard!

I had this problem about 2 years ago, and fixed it thanks to this video. Now it seems to be happening again! Will run off to get a souldering iron now!

Thank you so much, I did what you showed on video, and it worked. Total coast $7.20 bought iron and sodder. Thanks again

I can't tell you how much I thank the Lord for sending me to your video! You def saved us $470 plus labor and tax!!

Worked like a dream - took me about 7 min. Thanks so much for the video!

Thank you for posting this. Your video helped save me from probably having to purchase a brand new motherboard for my system.

Thank you!!! What an easy fix and it worked like a charm. Installer wanted $673.32 to fix it - my cost...$0.00!

Thanks for this fix! 7 years later and still useful. Cant say that for many KZfaq videos. Well my day off to fix this really paid off. Another tip besides the last couple of posts (sanding to take away the molten flux or getting rid of carbonized plastic) is to add lots of rosin. The rosin will prevent the formation of a cold junction. There could be some rosin in your solder, but not enough to rework the bad connection. That is perhaps why some folks here are fixing the K1 relay over and over again. Next time it will happen to me, I will take the board off and etch or scratch the part on the PCB that makes the bad connection to this relay. It may increase the surface area for the current to go through and to make a proper weld. Now I know why they install current limiters on their boards!

This video just saved us a ton of $$$. Thank you so much!!

Great! I just did it last weekend for the first time this season, and it didn't take the first time. Had to remove the solder and do it again. This time it worked. At least for a couple months...

Worked like a charm. Thank You! My unit was slightly different, but same results.

Worked great, thanks for making the video.

Thanks Drew, you save my life....funny thing is that it was black around the solder (K1) I just sand it around and now its working A1+.....

Just wanted to say thanks this worked for me!!

I just saw this video and did exactly what you said. Now it works!!!!!! Thanks so much so glad you posted this video. Thanks again you saved my lots of $$$$$!

Wow....it really works.Thanks all. I have had issues for many months, Error message started as "low voltage". Then went to no cell power. Thanks

You saved me a ton of money. Thanks!!!

Thanks for the video, this saved me a bunch of money

Thanks so much for this video! Husband just fixed it in about 10 min!! To bad the pool companies don't tell you about this easy fix!

Thanks so much! You saved me big time! This was my exact issue.

Thanks, Drew. I just discovered the breaker in my fuse box is actually bad so that may explain the problem. Have to switch it out with the replacement I just bought this morning.

Amazing, Thank you so much. Materials on hand, zero cost. Little sweat but worth $500 bucks.

It keep fix the problem... Thank for your nice video ... 4 years old , but still perfectly work :)

Worked perfect, thank you!!

Awesome. I CANT wait to check mine. Thank u so much and I'll get back to u with a result.

AWESOME! Worked great the first time! Thanks!

Thank you so much!! It worked perfectly!!

FYI, I've had to do this three times already just getting the pool cleaned up after winter. Also, I ended up paying $10 more for a better soldering iron, and it's worth it! This one is ready to go after 35 seconds. Makes doing this that much less painful.

Awesome! Now that it's getting warm, I checked on my system for the first time since the Fall, and looks like it's time to get my soldering iron out again, too. =P

FANTASTIC, My solder job looks worse than yours. The first time I fixed it, it took two tries to get it fixed and it worked for about 6 months and did it again. Another two tries and I am back online. Thank you for the great money saving tip!

THis fixed my issue - thanks SOOOO much !!!!

Totally fix mine!!! Thx for the video!!!

Worked like charm! Thank You. Anybody have a source for the nylon standoffs that hold the local display in place?

PERFECT! went and got some steaks to Grill out with the money I saved 15minutes had to solder it 2 times. I'd suggest removing the old/burnt solder first. Had I done that would have taken 10 minutes. Also be careful with the clips holding the Board, they get pretty old and brittle. Also my error was NO CELL POWER 2

worked like a charm

OMG! Thanks dude. Worked perfect. :-)

Thanks for the video just had to do mine and it worked like clock work,, thanks for the video..

Anything on aqua blue 47? Have same issue haven’t unbolt it yet hoping it’s the same easy fix.

just noticed the message "no cell power 2" on my unit. I'm also detecting an odor coming from the ProLogic. Would you recommend cleaning the burned solder ?

Ok, so I took it off, and i did not have a burned circuit. However, I did have a small spider cocoon that had formed near the plug-in adapter (white). I cleaned this out, and now the chlorinator is working. Ifound numerous webs throughout the unit. A search on the internet, determined multiple electronic failures (not pool related) due to spider webs. Spiders are drawn to the heat.So, I guess, I will yank cover every year and make sure I am clean. Special thanks for the video!!!!

I didn’t see what you fixed or how? Any other pictures? Thanks

i am going to attempt this tomorrow, i just wish i saw you do the actual job, dont know if i have to remove the old burnt solder, or just go over it?

Glad to hear it!

God bless you! It worked!!!!

it was the relay, i change it with aux 2 which wasnt being used and i am good to go... thank you

Hello, I have the same prob but with a little diff model. I have the Aqua-Rite with board part # GLX_PCB_RITE. The element that has created the burn out spot on the back of my board is round with the #'s - SL32-2R025 on it. Looks like I can save alot of $ here, but just not sure about how to remove the old one so I can install the new one. I could not get the video to play titles "Soldering". Any help at all will be greatly appreciated! Thanks so much!

... the machine shop said they worked. My voltage meter said power is reaching the motors, but the still won't start after reinstalling. Is there something on the Aqualogic circuit board that would burn out but still let power reach the motors? Just seems odd. Thanks for any suggestions (besides 'call an electrician.')

Are any people with this issue running a genuine Hayward chlorinator? I have a generic unit that I am using and wondered if this issue with the circuit board is caused by the generic unit. Thanks.

I realize this is an old video, but does the K1 relay also need to be replaced or just a simple clean solder? We also have a burnt out solder point, no cell power.

Nice video good job better than your soldering lol

@MacGruber14 great!

Awesome!

Thank you!

help, lol i did this and i got the numbers going, but i created another problem, the hi speed dont work, just the low speed works, any suggestions

So, I'm confused. Did you REPLACE K1 or just resolder the solder joint?

I am using my wifes account to respond, I looked this up and soldered a spot like you said and to let u know I am not the best Soderer in the world. I want to Thank you for Sharing this and Helping me and also I remembered you didn't plug in the sensor and remembered. Thank you again. What is normal running settings on Aqua logic pump timers and chlorinator settings?

Hi Drew. I got the error message today & pulled panel exactly as you did and saw same blackened solder point on the back of the board. I just fail to fully comprehend what the repair is exactly. Do I just place a fresh drop of solder on the original one ?. Or do I need to de-solder & replace the K1 part ? In your video you mention "repair that" but it seems its only a new soldering drop. I did try this (twice) and soon after got the same error again. Hope you can let me know. Thanks

mine is not reading no cell power it is showing chlorinator off high salt\amps anybody have suggestions on what this might be

Just fixed mine. Question, the old solder was dark like burnt and almost all gone behind K1. I cleaned it up as best I could using the braid and put new solder, turned it on and it's working. I'm just a little skeptical that the repair will last. Anyone have any thoughts?

What is the part number help please 😬😬

20A Fuse keeps popping, what may be the cause for this?

This worked for me, too, but I have a bigger issue someone can help with. The circuit breaker that my pump and crawler pump are one tripped while both were running. This has happened in the past and usually it's fine when I shut off the pump at the Aqualogic control panel and this flip the breaker back. This time it didn't work, neither pump would turn back on. No hum, nothing. I removed the pumps and had them tested by a machine shop and they said they work. (cont.)

I followed your directions and everything worked perfect, however about 2 hours later my pool turned green. I'm not sure what to do now. If you know what has occurred let me know. Thank you!

thanks, i just looked, and all seems to be ok, looks like i will need a tech. damn it thank everyone

Not sure which speeds you're referring to. Before you did the solder job, both speeds worked, and after, only one? My first thought, without knowing what speeds you're talking about, are that some connection came loose from the board while you worked on it. Check all the cables and wires. The place you soldered has nothing to do with pump speed, or pump anything, in fact.

Wish I had something helpful to say here. I'm not much of an expert on the system as a whole. You could try the forum at the nocellpower website. Someone there might be helpful.

Im having touble getting the board out

I am a pool technician and this guy is crazy, I hear he is locked up now. Don't do this at home, pay me $1000 and I will fix it right.

Thanks - but get a tri pod!

Worked perfect! Thank you.
