I worked as a apartment maintenance engineer. For about 30 years before I retired. I was in electronic radio repair in the military, went through 2 different schools for different MOS before my time in the service ended. I graduated top in both schools. So I was pretty good on low voltage, After I got out of the Army I worked as an electrician apprentice for a few years Installing power in houses and office buildings. So I gained a grasp of the higher voltage. I got into apartment maintenance and the old supervisor taught me about air conditioners and refrigeration and the refrigerants and I went to school and got my certification. the last job I had before I retired I was on for about 20 years. The ground in that area had a lot of minerals in it and it just seemed to attract lightning all the time. We would have a lot of those control boards going out on our heat pumps. If you are new to the AC repair field, get training at a school , things are changing and getting more complicated and newer gases being used, knowledge is key to a successful career.

[@dmc31405]

Watching a Pro Pull a Rabbit out of a hat. Priceless... I bet those people in that house have no idea how blessed they are to have you working on their HVAC.

[@CharlesSmith-hy3hl]

Persistence!

[@janchristensen7993]

Fantastic Curtis. You are a real technician. You didn’t give up and got him going. I do watch all of them but this one I really paid attention to. Good job. 👏

[@davidadowlen]

You have lots of patience 😇

[@kg4muc]

I thought they were sending the fire department your way a little premature 😆 The magic smoke hadn't even been let out LOL

[@OcRefrig]

Wow, What a video ! Bottom line you got them cooling. Congrats ! i Attack FUSE BLOWN calls a little differently in Package 📦 units. 1) Whenever i Have a Fuse Blown on a Package unit i Want to know if its a Thermostat & Wire Issue or a Unit issue. 2) First - Disconnect thermostat wires from unit. 3) second - Jump out unit with jumpers or Home made jump box & Make sure unit Works By itself. Run for 5 minutes Min. Check cooling & Heating. 5 -10 minutes each. if All is Well. 4) You know where the issue lies. thermostat or wiring. 5) Disconnect thermostat wires at thermostat. 6) separate all wires at both ends and check for shorts between wires. if all good 7) Replace thermostat & Sub base Complete. Never replace half a thermostat. Do some fresh connections. that way u know all is good. Crazy Video Curtis. Bottom line you got them some cooling. That's all that counts right now on a friday afternoon. with some heat coming in. Can't wait to See the board install video. that's going to be interesting. maybe our maybe not. who knows with hvac calls. if You are Getting shocked with 24 volts that bad You might want to start wearing gloves of some kind. humidity must be very high. i'd Recommend getting a box of nitrile gloves and throw a few in your tool bag. take care curtis.

[@mikemaki1104]

the cleanest unit i have seen you work on yet!!

When i saw the sparks i thought that’s my man. 😂

[@williamtorres3394]

You have more patience than me I would !!! I would have lit on fire 🔥!

[@OcRefrig]

🤣🤣🤣🤣

[@ziggidun9584]

😂😂😂 seriously

[@DelticEngine]

Fascinating video, Curtis, and well done on getting some cooling sorted out. That control board looked like it was at an odd angle. Personally, I would have taken it out to examine it and see if there was anything going on behind or with the board mounts that could be causing a short. In my experience, when a job starts getting longer and longer I start pondering if I've missed something hidden in plain sight.

[@dennislyon5412]

2/3 of the way through this one. . . are we into that fried critter behind the board trick?

[@Zeviticus]

That was riveting. Having these kinds of issues terrify me. Customer watches you go back and forth from equipment to tstat, then you can't get the part they need.

[@OcRefrig]

Sometimes if it's troubleshooting & it's a odd one i'll ask them if they can give me some space, tell them i need to concentrate on a Wiring diagram etc. if they still don't get the hint i'll say - How Would they like it if i was breathing down thier neck at thier work. i need some space to think & zone in. i'll come get them when ive got it figured if they wish. but sometimes you got to be alone to figure it out. allways - Just stay calm though. Remaining Calm is Key. it's Just a Job. We can only do what we can do.

[@TomLawson05]

Great effort Curtis getting them air thanks for the video

[@HVACGUY]

You bet

[@stevencossaboon3237]

Excellent work Curtis.

[@HVACGUY]

Thanks

[@Paul-IE-Repairs]

my suggestion when chasing down a short, disconnect the bonding wire from the common at the transformer to prevent false positives as well as remove the thermostat and then begin checking for shorts to ground. ( isolate the circuits and execute a search)

[@kens.3729]

You Can’t be Stumped especially with your consistent and strong 💪 efforts. 👍🙏

[@johnnypena9682]

Man that transformed is the champ good job

[@hinspect]

Lost me somewhere, but great job bypassing the circuit board. Thanks for the video!😊

[@sknight0391]

.29 min when you were walking in humming, that reminded me of the swedish chef on The Muppet show. 😆👌😎👍

[@HVACGUY]

Lol😂

[@user-oj1ri5ld3x]

All right still going the extra 10 miles for clients

[@user-ud5zx7ln1y]

Compadre su nombre ahora es San Curtis. Saludos desde Chicago

Saludos y gracias

[@thwompalot5000]

My go-to is "Well, that lives there now."

[@OGHVAC]

Great work getting that tenant cooling for the weekend. I have been in the business as a tech for 44+ years. Having a dog with a bone work ethic to get the customer cooling is rare. I can't tell you how many times I've been working longer hours than I wanted just to get the system to cool. Now in the heating season, there's only so much anyone can do to get heat SAFELY!!!

[@rolytech212]

Am seeing the Helicopter around 😎

[@mansurniazz]

Great troubleshooting video.

[@pcsof33]

Great work but please take care of wearing insulation 🧤 .

[@s550wulf9]

Killing me Curtis, super easy that you made complicated. First off shut the power off. Remove contactor low voltage wires from contactor, leaving the common from transformer on the right side. Run a piggy back or jumper off the 24volt hot side of transformer to the red thermostat wire. Then take the blue/black thermostat wire whatever they are using for common, connect to right side of contactor coil. Then take a wire/jumper from the yellow thermostat wire and connect to left side of contactor. Now when you call for cooling compressor and outdoor fan will engage. Now take a little brown fan relay (24v coil), run jumper from green thermostat wire to relay coil, from other side of relay coil run jumper to right side of contactor, now you have complete path. Then take the high speed from indoor fan place on the (1) contact on relay and the fan motor common and place on (2) contact (basically the NO Contact). Boom fixed till Monday. When the thermostat calls for cooling the thermostat will send 24 volts to the contractor and indoor fan relay coils, closing contactor and the NO contact engaging indoor fan and compressor/outdoor motor

[@billj4859]

Just wire the motor hot and don't bother with the relay. Easier, and you don't sacrifice or have to charge for the relay. The cooling will still cycle with the thermostat.

[@s550wulf9]

@@billj4859 agreed, but some customers will complain about the fan running lol

[@alfranca5961]

Curtis is in it for the win. Not for the come back later

[@billj4859]

@s550wulf9 You're correct. Some will that's why I give them the choice. A little noise or no cooling or no heat depending on the season. It's their house, not mine.

[@krishuntzeroable]

Ok captain hindsight.

[@JoseRodriguez-xh6qo]

Thanks for sticking with it.

[@wilsonhortman4110]

Why didn't you ck the codes first???

[@paulbryant68]

i just noticed the helicopter by him. Haaaaaaaa. ole C ignorin’

[@OnusBones]

Now that was irritating. I guess there are no generic boards available, allowing you to have some kind of spare?

[@jenko701]

No smoke detectors, but fire trucks this time ., great video

[@HVACGUY]

Thanks 👍

[@scottbush8767]

Curtis: You should change your company name to HVAC DETECTIVES. Also WAGO connectors are your friend! LOL,

[@hightechhum7402]

Silly thing but you might want to try wago connector when working on jobs like this. They makes it so much easier to connect and disconnect wires

[@TheFatesLieutenant]

Glad the firetruck didn't pull into the driveway you were working at!

[@PhilipNation-xm5lh]

Those low voltage shorts are always fun. Looks to be a fairly new unit. Warranty? About as much fun as attempting to do warranty work for ICP. How many other folks have trouble with them? Not a distributor....nope....well we can't warrant the part. AND...there's no other ICP dealer in town!

[@gtpforever]

They're one of the only manufacturers that require us to send them parts back and require us to install their replacement part that they send us. So we have to get a customer going with our parts and then return later with the manufacturer warranty parts to replace the item for the second time. Lol

[@Chainsaw600]

Yep. That’s exactly what I’m doing. I pay out of pocket for the fan motor and have to send it back for a credit. Not very streamlined.

[@jthonn]

Nice job. i knew you would get it.

[@gregsidel3557]

Damn good job looks like you know what you're doing got that guy fixed up even though he had to rig it but he'll be good for the weekend good job good video

[@metalillness5951]

Great job for hanging in there for the weekend win! Thanks as always for taking us along to learn with you. Sure felt bad for you with the tenant shadow, that was an unfortunate thing a guy doesn't need.

[@J-Colt]

Nice seeing one of those units not sitting in mud for once. Thanks for posting

[@neilcvids2583]

that was some master wirecraft

[@StringDriver]

I think it would be fun to have all of the “experts“ state their occupation and years of experience in this industry, so that people can really give them some weighted values for their opinion.

[@cbar30]

Cat quick reflexes on that arc🤣

[@kevindschlotzhauer9299]

had to do it that way few times myself

[@bradmeekakasilvertopflyer]

How did you know I love fire engines and trains????? Good video ....

[@robd7365]

Nice work

[@fernandobazan829]

hey are they coming for the A/C lol omg it must be a three alarm fiasco lmaoooo

[@TimTakacs]

I've run into thermostat problems many times. But it certainly could have been wire to wire short too or contactor windings. Gone from Y to contactor bypassing the board many times to get them cooling. Process of elimination - Good Job

[@wallywal5475]

You got skills

[@bugeyedwillypetfarm9625]

Had the same thing a couple years back mice chewing on tstat wires

[@GreyRockOne]

A little sloppy but it's working.. As "Anti DIY" TED would say, you have a low flying helicopter nearby..

[@Bryan-Hensley]

I came out of the electronics field into HVAC. I love finding low voltage issues. I never ever apply power until I find the problem. It stresses out the electronic components. You need to know the ohms of all the components like the contactor (14 ohms) and find the short that way.

[@co5863]

this guy got an eye problem i i i i i he knows everything.

[@robertStone-hq1by]

I have had this problem and to get temporary cooling it’s not easy

[@joaquinsosa4693]

Hope it doesn’t freeze up. The blower won’t ramp up without Y input.

[@user-qd6ir5qg2v]

Get the crimpers with the orange and black handles, better crimpers than what your using

[@fidenciomartinez3339]

You're going to have nightmares 😂 that unit just whip you 3 times showing you who the boss is. Anyways, it your yellow wire shorting out from the t-stat. Your welcome.

[@joshuasanchez3107]

[@tonydelgrego2906]

Would a universal control board work

[@terrygrant8126]

I don't mind an audience ......but when their are clock watching when I'm under pressure, i try to maintain my attitude....

[@frankdillon6127]

i have the 25 year old Honeywell mercury switch thermostat never lets me down.

[@richardambrose3156]

I hated them Friday Calls and every supply house is closed or closing.. I feel for ya...

[@stephennichols4815]

Didn't you j7.p it out at the unit and it ran when you had the thermostat wires disconnected ? I would be looking for a problem with the thermostat wire

[@sergiohernandez4163]

Them icp has lots of problems in my area with burners rusting out also behind the inducer motor.

[@bubbabubba2013]

Sounds to me like the house is on fire 🔥📛👨‍🚒, run for your life!!!

[@TheBdog2009]

Add to the invoice to Homeowner $100.00 an hour for your tenant hovering watching me work!

[@joehead1294]

Tenant a new biden voter. Maybe more...

[@harrydickson4575]

👍👍👍

[@jorgenieves9787]

Thermal imager and you would have find the short quickly

[@swanjaymusic]

Did you get to replace that board ????

[@wilsonhortman4110]

Why didn't you ck the codes first. Why are you looking at the high voltage circuits . The fuse is in the low voltage. You didn't have to go back and forth to the t stat. Just connect red, yellow and green at the unit.

[@woodystokes1543]

You’re a glutton for punishment, never put a cover on until the end 😊 nice 👍🏼 job

[@bugeyedwillypetfarm9625]

3 amp

[@user-qd6ir5qg2v]

I think their klein crimpers.

[@wilsonhortman4110]

Worst case of trouble shooting

How come you don't tell us what exactly you're doing you show us the video of but you're not really telling us how you doing it what are you doing
