Oh yeah?? Well I'm only a fetus! But I have learned SO much from these videos that I'm going to get my HVAC certification and begin work immediately after I'm born!
It's like the refrigeration cycle. You teach us invaluable lessons. Other tech's teach you different options. Which in turn, teaches us more invaluable lessons. Lovin' it!
Well, I appreciate you taking the time and putting in the effort in making these videos. It's not just a great resource, but it helps to see a fellow technician going through the same crap. Makes the trade more of a community.
I have been watching your videos for a while now, and I am still impressed with how your methods and basic practices go beyond the HVACR trade. I continue to watch and try to absorb ways that I can improve from you as much as I can in how I troubleshoot in my trade.
I get locked up compresors all the time. Also Ive learned a couple more stuff from your videos thankyou for taking your time to make this videos public it really helps a lot.
I had my department buy me a few of these 3-N-1 hard start kits for this very same purpose. I like to use them to isolate the compressor from the starting components. They were throwing away refrigerators at work because no one knew how to test them at least electrically except for me. A stainless steel fridge that retailed for $1700 new was almost destined for the junkyard but I was able to find a defective PTC starting device which cost $67 at APC to replace. Small domestic units are good units to learn the basics on.
I'm not even an HVAC tech, just an electronics/electrical tech with an uncle in the trade. I didn't even know what a PTC starter was, but I was able to determine that the mini-fridge at work had a bad one. I then applied my knowledge and was able to actually repair it. I had to repair it again a couple years ago, but that dang thing is still running today. Eventually I'll need to actually replace that PTC starter.
75 degrees and sunny today here in Brookfield WI. Dew point around 50 degrees. Just right. T-storm season is upon us. Had some daisies already. Oh... Your anger is just misplaced frustration. Simplify your life and discover the things that truly mean the most to you and live for those reasons.
And thank you for posting these videos . They really give me a great idea on how cooling systems work . Another plus is how you talk to us like where worth something . Thank you.
I think that a compressor going bad on a fully working cooler with a somewhat clean condenser and fan, it's mainly because of the compressor itself. the owners might just had bad luck on this reach-in.
This is another good service walkthrough. If I had to guess why the compressor died I would say that membrane infront of the condenser. They seem like a good idea but when the humidity or ambient rises they tend to cause problems. Also I know you know its locked rotor but perhaps showing an amp draw on the common vs the RLA for the rookies please?
Good job..I feel like it is very useful if you explain the concept of the troubleshooting in little detail along with causes and actions to be taken. I know there are a lot of experienced people here but for new buds it might be very useful. Thanks and much appreciated
Thanks for watching I will be going live on TH-cam this evening 7/1/19 @ 5:PM west coast time to discuss my most recent uploads and answer questions from emails and the chat. Come check it out if you can th-cam.com/video/rlHkdZSIjdU/w-d-xo.html
Really Great Job from a colleague from Amsterdam Holland I watch Channel all the time and I'll earn a lot from you Sometimes It's Little difficult Because you measure with other pressure and temperature
Thanks for the video. How often do you end up changing compressors on these small units? It seems everyone just want to through it out and buy new these days.
Hi , Chris , great vid as always . Couple questions if I may : _ I've never heard of a compressor analyser , could you if possible make a vid on them one of these days _ if the system doesn't have any pressure control , couldn't it theoretically start and run even with no refrigerant at all , until the compressor burns out ? _ how to test the starting components ( I'm not sure how to do it , other than ohming the contacts and check it does have continuity where it's supposed to , so I'm trying to learn how) _ and last : are the pinch off tools reusable , or does the needle not pierce properly once it's been used , or is the gasket not tight anymore Thank you so much again , I really need to get better man, it sucks to suck at my job 😞 !
Came across a traulsen cooler and the Compressor keeps short cycling. Pressures look good in the short time that it runs. I found that the cabin sensor and the discharge sensor was bad. I change those and the error code went away but he compressor keeps short cycling. The next thing that’s a head scratcher is the door sensor says the door is open and the door is not open. Kinda lost I this one.
@@HVACRVIDEOS before TH-cam who would have ever thought a good competent service tech who enjoys training people would gain near celebrity status. Keep up the good work.
They're like Hobart, they don't play ball with outside techs very well. If you're not a HVAC/R technician trained on ice cream, you're just going to screw it up anyway, they are very picky units with a very specialized skill set
They're generic. The 3 in 1 isn't tuned at all. it's meant to start up the widest variety of compressors possible. Conversely, the OEM starting gear is purpose designed to start that specific compressor. In my personal experience with non-HVAC motors, the overload unit is the most valuable thing to have tuned to the specific motor. Though having a tuned capacitor that's the correct value will improve current draw, which could become a problem if your unit runs heavy load often.
Don't you like to check these compressors starting them directly with wires? Line to Common, neutral to Run and a little tap to the Start with neutral to simulate the start relay. (I said neutral because it's the mono-phase 230 VAC system we have here).
Do you understand how start windings work? If you don't have a relay to drop off your start windings you're going to lose all your magic smoke and make a bad situation worse. Call a technician please, it'll end up costing you less in the long run
@@mojoemurphy Hi Mojoe, I just talked about simulating manually a start relay, just tapping the start connector during a second. It's for check if you hava a bad start relay. It's not new, is completely old school. Here you have a video about it: th-cam.com/video/dumKbEtHL34/w-d-xo.html Cheers.
Good video I do commercial and residential for the LA County, We don’t do refrigeration few wind rooms in what area of California do you work ??? Video very inspiring I will get the two books you recommend on a previous video chat
Hey man quick question, My AC turns on and runs, I can hear the compressor start before the fan. Both lines to and from the unit are at ambient temp. I don't have gauges, but it suddenly stopped cooling. If I tap the Schrader valve there is definitely pressure in there. Could it just be low charge? Or possibly bad valves on the compressor? It's 28 years old.... Lol
You'd need gauges to test, if it's that old and not tripping a circuit, one easy test is to put a clamp meter on a compressor line, find amps, and look on compressor or data plate, should say LRA if your amps are close to that it's dead. Probably makes a noise right before it shuts off on thermal OL. Giving you the idea it came on, yet not compressing anything, therefore no noticeable temp on refer lines. Edit: if it's not this exact scenario, or even if it is, you should have someone familiar with the work and tools check it out for you.
@@jaredsciguy1634 thanks man. I feel like I have a limited grasp on the concept. I ordered a set of gauges just to check it out and see what the pressures are while it's operating. I appreciate the advice.
Yeah. I feel he is a bit too excessive in just-in-case replacements. It isn't always best for the consumer. The expansion valve he said, he have seen many failing and it could have been source of compressor failure. So that was a good call. But replacing condenser coil seams weird to me, especially as the unit looks very clean and in good shape overall.
He replaced the hot gas condensate loop which is not the condenser, it is about 2 feet of copper tubing that helps evaporate condensate from the evaporator. They leak often and if the system is open it is cheap to add it in as a preventative measure because the expensive part is tearing open the system, not the parts
@@mojoemurphy Sounds a lot like how my dad (an auto mechanic with 40 years of experience) will try to get customers to replace the water pump at the same time as the timing belt, on cars where the timing belt drives the water pump (most import and domestic straight-4 engines). It's just more parts cost, the labor stays about the same because you're working right in the same area so it's really not worth it to try to save money there. Also, if your motor has a timing belt, chances are it needs to be changed about every 60-90k miles (consult owners manual or service information to get the specific mileage). It wears out just like any other belt, but the consequences of it failing might be a roll of the dice to see if you bend some valves, because these days many engines are designed in such a way that the valves when opened by the cam and the piston at Top Dead Center, will try to occupy the same space. This is called an "interference engine", and they perform better than non interference engines but the downside is that if the engine jumps time (meaning that the timing components have failed), you have a high chance of doing severe mechanical engine damage. This can break pistons, but it's more likely to bend valves and damage valve guides, and fixing that means taking the head to a machine shop for inspection and installation of new valves valve guides etc. Much more expensive than just replacing the timing belt and timing belt idler pulleys on the manufacturer recommended schedule with OEM parts.
Good vid but you should always check your voltage also those 3 in1 start kits only have a start cap rated at 88 mfd I would bet that compressor calls for a much higher mfd good vids bud
No it's not a mega ohm meter, a compressor analyzer is a tool that has the ability to start single phase compressors without using their starting componets. The analyzer contains it's own starting componets and instead of a potential and or current relay you use hand operated switches. If your working on a 3 phase compressor you also have the ability to reverse the compressor rotation by a switch instead of physically switching the wires. On single phase compressors it was good because it allowed you to start the compressor before you left to get new starting componets. Like I said In the video it was kind of put out to pasture when 3 n1 start kits came out. Here is a link to a newer one (amzn.to/2J1TwNL) but this one doesnt have 3 phase rotation
I am freaking 14 but you've taught me so much about HVAC that I do not know what to do with it... Thanks
Oh yeah?? Well I'm only a fetus! But I have learned SO much from these videos that I'm going to get my HVAC certification and begin work immediately after I'm born!
I love that you try to find why the compressor failed. Anyone can replace the compressor but everyone can find the reason for the failure. Great job!
It's like the refrigeration cycle. You teach us invaluable lessons. Other tech's teach you different options. Which in turn, teaches us more invaluable lessons. Lovin' it!

Hi , Chris , great vid as always .
Couple questions if I may :
_ I've never heard of a compressor analyser , could you if possible make a vid on them one of these days
_ if the system doesn't have any pressure control , couldn't it theoretically start and run even with no refrigerant at all , until the compressor burns out ?
_ how to test the starting components ( I'm not sure how to do it , other than ohming the contacts and check it does have continuity where it's supposed to , so I'm trying to learn how)
_ and last : are the pinch off tools reusable , or does the needle not pierce properly once it's been used , or is the gasket not tight anymore
Thank you so much again , I really need to get better man, it sucks to suck at my job 😞 !
