Blown Fuse Leads Me Outside

[@Biarkii]

Hey Curtis,Im a residential installer and I have really learned alot by watching your videos.what i like about you is that you take your time and do things as best as you can.

[@romeoser5397]

My mans was complaining bout no room but my boy installed these

[@jthonn]

Nice being able to repair one without having to look for a leak. Nice job figuring out what it was.

[@BlueDinnie]

I laugh hysterically every time that brush comes out 🤣🤣🤣

[@TomLawson05]

Good call on the contractor

[@HVACDaily]

I’m from small town Alabama & have been doing HVAC for 6 years now, i love coming to your videos & learning & seeing how others go about diagnosing things. Keep up the amazing work man!

[@robertgentile4498]

Love the popper,use it All the time.better then the pile of fuses on the ground after I find the short.

[@whizzo55]

I am just a DIY home owner with a little knowledge in electronics and a/c systems. I had that happen to me on my old Goodman, fuse blown, put another in and blew immediately. checked the coil on the contactor with my Fluke and it was shorted and had just replaced it a year before because of ants. Luckily I was working at Grainger at the time so it was a cheap fix. Love your videos!

[@joehead1294]

Nothing at Grainger is cheap. Employee discount maybe.

[@whizzo55]

@@joehead1294 As an employee it was way cheaper than going to the local supply store.

[@Bryan-Hensley]

You got lucky. Sometimes the wiring gets soaked and causes internal short. Sometimes it's a float switch shorted. Sometimes it's the reverse valve coil. Sometimes it's an internal short inside the thermostat. Sometimes it's the controller inside the ECM. Sometimes it's the defrost board. Sometimes it's the fan delay board. Sometimes it's the heat sequencers. I can keep going.

[@bobgallo3775]

@@Bryan-Hensley That is why you have a meter. I have seen stinkbugs cause a problem with the defrost board, they like to climb in back of them.

[@Bryan-Hensley]

@@bobgallo3775 I went on a service call a couple of winters ago where the customer heatpump wasn't getting power. I went inside, smelled something burnt, took the breaker panel off and it had caught on fire inside due to it being absolutely packed with stink bugs. They were crispy stick bugs at that point. Some of the Romex connectors were missing in the top and the fire had blacked the 2x4s above the breaker box. He's extremely lucky the house didn't burn.

[@ginny8765]

Really wish you worked where we live. We got a new ac last year and ever since we got it, it just doesn't work properly. I just turn it off inside cuz it is annoying. When it is super hot out my home really doesn't feel cool. When it is cooler out and I forget to turn it off it runs and runs and my home is too cold. I called and told the company and they just want to keep charging us for what we should of had from day one. At times when it runs my home feels like it wasn't drawing out humidity and the house felt musky. We told them but they just want to keep charging us. Love watching you work cuz it reminds me of growing up and being dad's helper. I am female and I grew up being dad's boy ... God bless the work you do.

Good job Curtis.

[@bobboscarato1313]

I remember systems not working due to dogs chewing the low voltage wiring before it enters the outdoor unit; found this many times usually covered the area with chicken wire. In one extreme case owner had a German shepherd put that chewed the wiring and the insulated suction line. Told owner "sorry this isn't covered by extended warranty" Owner cheerfully paid the repair bill.- I suggested he enclose the entire unit so he won't have a repeat performance!

[@jthonn]

Would help too, if they would feed their dogs and give them some attention.

[@Bryan-Hensley]

I always run the low voltage in flexible conduit.

[@andydavis3739]

On a 24 volt coil, if its above 20 or below 10 ohms replace. 2-3 ohms is shorted. Worked for me over the years

[@IIUzzymanII]

The company I work for installs Ruud. Had 2 HPPU that sent me on a bit of a head scratcher this summer. Both times was the contactor. Also had a Ruud dual fuel, not our install, and the contactor also went bad. All installed within the last 6 years. Might just be a bad batch I assume.

It would be nice to teach us how to connect the vacume pump to the contactor to get it to run when using pump for vacume procedure.

[@rupe53]

seems like everyone has that handy vacuum attachment these days. I don't know why someone didn't invent it 50 years ago! BTW, I use it on just about every service call these days.

[@tphvac87]

Nice work Curtis that contactor is shot, I’ve come across similar situations when I ohm em out they are mad low, good troubleshooting bro! I’ve had contactors that have blow fuses before I guess they short out and blow the fuse

[@Eddy63]

Good vid and good info ... Thx Sir ...

[@robertpenczar8930]

very nice

[@snidelywhiplash8923]

What do break yellow and break red mean? Is the fact you changed it mean it was done wrong? Thanks

[@HVACGUY]

The water sensor opens a circuit when it senses water. Breaking yellow just turns off the condenser. I swapped it red so that it will kill power to thermostat and condenser - which will immediately cause a service call, and then a trip to the attic

[@joehead1294]

Compressor wiring connections with fast-ons make me a little nervous. Lotta current riding on thin tabs. Sorta like heat strips, too. YMMV.

[@mikehammer6909]

I did a install and on start up had no low voltage and had to trace it from outside to attic to the float switch that got a low voltage wire nut underneath it during install

[@frankroper3274]

I'm a backwards kind of guy. I would start at the contactor and if it has 24V and not pulled in it is bad. If not I would go to the tstat and if good then the air handler and if fan running check the relays there and sequencer there.

[@Killinza89]

Why put a trap outside? To me that sounds like a problem waiting to happen if debris gets lodged in there. Genuine question if someone can clarify.

[@michaelburgess7703]

Yeah a couple of tree frogs to get in there and then probably the snake will follow the tree frogs up the pipe all the way to the air handler I wonder if there was any in there sometimes.

[@wadespring7123]

The only thing that I can think of is that whoever installed it knew enough that it has to have a trap, but was unaware of the importance of where that vacuum trap is.

[@stephenbierlein2517]

Instead of using circuit breaker on low. Hook up volt meter and you can see the voltage drop. I would do all wires where the voltage drop is check then with ohms on that circuit. Have a great day.

[@Bryan-Hensley]

The amp meter will find the short without taking any wires apart.

[@rupe53]

@@Bryan-Hensley ... the problem is a draw over 10 amps or so through the meter will blow the internal fuse. (more expense) Running a jumper instead of a fuse and using an inductive meter may blow the board. Using a volt meter in series is a good idea.... but you have to guess where the draw is first so you can do the test. Usually I would disconnect everything then reconnect one at a time.

[@Bryan-Hensley]

@@rupe53 just bump the power on. Like 500 milliseconds. And yes you'd need a suspicion

[@rupe53]

@@Bryan-Hensley ... in the automotive trade guys use an incandescent test light across the fuse holder. A short will light it full brightness. Find the issue and the bulb will only glow dim. The trick would be to find a 24 volt bulb. They are out there if you look hard enough. This is probably the oldest trick in the book to find shorts.

I’m getting concerned about your shortness of breath…you also sounded like you were wheezing too…take care P.S. Why a trap at the end of the condensate drain pipe?

[@shawnbologna8281]

Heat pumps are negative air pressure and have to be trapped..a gas furnace is positive pressure so they don't need a trap

[@Bryan-Hensley]

You can put the trap anywhere in the line. When it's in the attic the weight of the water will help keep the trap from clogging up when it's at the lowest point.
