Frozen Air Conditioner Multiple Issues

all right so i have a no ac call here and well it looks like it's frozen up on the line set nope yep we got ice that's for sure boom we're frozen so let's just scope this out see what's going on let's turn the power off now supposedly they have it off inside there's always interesting information that comes out when you're on a job started off that it just wasn't cooling and blah blah blah and then that maybe the thermostat was at 64. so but with everything off i'm wondering why this is still running that's not going to help me that bit way too big so let's see what's causing this or maybe they're pointing me to the wrong thermostat never know this needs to be off anyway for a while as this melts this one out all right one thing i don't like is when people put the electric so close this won't come off it's like why i should have to bend it to get it out all right so see i mean it's frozen to can go down no more all the way to the base it's like i'm going to keep freezing i'm frozen oh look at that contact there looked a little dark it looks a little cooked on the top part so low voltage comes in here yes whatever you do if you want to see if you got a stuck contactor don't shake the unit too much sometimes it'll let go let's see and it's not a stucco actor so something else as it's still running when it's supposed to be off which is telling me that maybe either the thermostat stuck on or it's the wrong thermostat they're pointing me down i'm going to recommend swapping this contactor anyway this is starting to get burnt but for now that's not my problem so i don't know if i don't know if on off doesn't help that we've had some warm weather and then the last two days have been cold so we've had the warmth like it literally dropped from like 75 80 down to 50 40 at night sometimes so i'm gonna have to go inside problems at the doctor's office i can't really bring you guys with me right now cool one is on maybe this is listed as one okay that one's listed as one but this is zone one i can't read that but whatever no schematic doesn't matter so zone one's on still got to locate that all right so i traced out wires i believe i found it so right um here it's solid you could usually just push them right in okay i feel like getting a piece of solid wire all right tired of fighting with this connection so why two other tiny little holes very hard to get into when you're on awkward angles so by two by one okay in and let me cut that down just it should be good okay and have a bunch of these i don't want to use them i heard they loosen up over time i'm probably gonna come back and fix this but okay connected nothing on okay oh not much more i could do right now because it's frozen actually i could check the contactor now because here's the other zone of the zone so here's this zone but the problem with this zone is that there's no zone valve it's to the air handler and for the hot water coil so i don't have any zone damper to control that's very strange i was wrong i got a zone damper over there so this duck always goes that room but then there's one back there in the back it's an open zone all right so i found the problem right here this common wire is off for this zone [Music] so after searching around and checking things out this is something i found was that this zone is not powered look it's in the closed position so i'm gonna have to fasten that in and you can't do nothing with the charge until it melts but this will definitely freeze it up i'm feeling air oh yeah the wire was disconnected i don't know but i found this wire up here not attached maybe we could air in this way and it was shutting off the damper going this way this might take care of your room yeah i think something she hasn't had here and i don't know how long has it been six years never had air in here wow because the wire was just not plugged and the funny thing is when they pump i've never seen them in this area only right there where you want people that's usually all they go to is the air handler but because it froze and i can't do nothing on a frozen unit other than make sure everything electric electric is working and now i'm going to mark the same thing where everything is so this way somebody knows there's his own damper here there's a zone damper in there they only go to those two things right there yeah the control box is in there yeah yeah but i'm going to label i don't know if i have a labeler but i'm at least with the marker i'm going to put a zone there right here so in the future somebody knows so they're not like i was i was looking everywhere for him thank you fans on damper's opening at this zone they haven't had air for a while this will definitely be a reason for freezing green light it's open i hope you enjoyed this until next time if there's anything with the refrigerant charge i'll continue this all right so it wasn't just a closed damper i got a condenser coil over here right here so i gotta replace this unit it's very slowly leaking but they want me to charge it up so charge it and then get out of here it's written up sales already knows about it they want to replace so that's all i could do get it running for now and then it'll be swapped out they know it may not last at all there's an oil spot here but i really couldn't get anything and check this out this is pretty disgusting here's the condenser coil it's like a rug so uh probably overheated and blew a few holes who knows but i'm gonna be getting out of here i'm just gonna charge it up later guys i hope you enjoyed the video peace i'm out
