Trane package unit problems

This was a service call on a Trane Package unit not working,I found that the unit had a bad compressor contactor, a dirty condenser and it was a little overcharged. Give it a watch and let me know what you think.

A note for the guys who are new to working on these units....if that is a YCD036 RTU, know that the three pole contactor only breaks two of the compressor phase legs. The other pole is for the condenser fan motor and the crankcase heater. Never assume that a three pole contactor breaks all there legs. In this setup, that one unbroken leg will make everything hot, and a shock can result if you assume that side is dead. It isn't dead. Turn off the disconnect and look inside to make sure ALL power is off.

Hey Chris, without a doubt & no disrespect to the other guys who make HVAC videos on YT, I have to say that your videos are hands down the best out there. First of all I like I the good audio & visual quality of your videos. Second of all I feel like I am a apprentice out there on the jobsite with you as you are teaching me the fundamentals of troubleshooting HVAC & refrigeration equipment. It is not uncommon for me to watch the same videos numerous times trying to squeeze out every tidbit of information I can get from you. I also make sure to take notes from these videos that I can use for future reference. I really appreciate these videos. I also love the recap where you discuss the situation & how you corrected the problem. You have a real talent for teaching & instructing. Keep the videos coming!

[@richardmorinelli9931]

Great thoroughness in your service call. Most techs would have just changed the contactor and got the unit up and going again. Not only did you get the unit up and going again you got it running properly.

Richard Morinelli Unfortunately you are probably right. I do right by the customers because they are the one’s paying the bills. Sometimes though there are too many calls to spend the time necessary to do what’s right.

[@livingstones1196]

Just a friendly suggestion while testing the contactor. While the contactor is engaged (system hot) and the cover off like you had it. Perform a voltage drop test across each "contactor" like you did while toning except set meter to voltage so you will be checking voltage drop, you should read 0 volts, anything significantly greater indicates a problem, this way the system is loaded and you can identify which contactor is "dropping" voltage. The problem with performing a continuity test is the meter only lets out a very small current to pass so if there is high resistance in the circuit, the small current will still pass through and the meter will indicate continuity which falsely confirms a good connection. but when you load the system down only a small amount of current passes through because of the high resistance in the faulty (in this case contactor) hence the voltage drop across the faulty connection. Remember, resistance is a robber of voltage. Great video! Sorry for my winded explanation. You definitely nailed it though.

[@38911bytefree]

Issue with tone test is ... the tone test uses just mA current. so there is a slim chance that a failing swtich or relay pass anyways because is not under actual load. Also, tone circuits (cont test) are not well protected in meters. If for any reason happens the circuit have voltage you can blow the meter appart no jokes. Im talking about 100 to 200 dollar range meters. Of course this is not happening with Fluke, Brymen. You dont need to go nuts with a Fluke, Brymen is fine. I dont do HVAC, but use meters a lot, I dont have a Fluke. They are sky expensive here ... so Im using a good price / performance meter but it is unprotected. You need to walk very carefull with them. I do power supply repair and 311V DC is all over the place. I will get a Fluke in the end. But you need big bucks for a decent one like the 87, 89, 289 etc.

[@NotPridesfall]

Good call. As an automotive mechanic, the voltage drop test is one of the most helpful diagnosis techniques that practically nobody understands or uses.

[@dunckeroo1987]

When the contacts get corroded they will start to act like an oxide semiconductor and have a nominal voltage drop that creates lot of heat. Eventually the oxides build up and voltage drop increases to a point of blocking instead of conducting. Thus voltage drop method can also tell if a part is on its way to failure.

[@markdennis4170]

[@jimkey920]

I just call them orifices. When checking a Trane lean the access cover as tight as possible. , to gauge head pressure. Very important on larger units with multiple fans and compressed. I appreciate your hosing the roof down. Good lob. I am retired after 50 years on A/C and Boilers. I once went on a heat call on Florida. Th store had 6 Roof Top Gas units with A/C. There were 6 gas lines stubbed at each unit, no new were ever connected in the 5 years since built! North Florida had gone into the teens!

I do cap tubes and orifices as the same. And you did have that condenser section door panel on when you were checking it right cuz the fan will pull true the least resistance opening.

[@Sagittarius-88]

The contactor issue is a great example of why loaded circuit testing is so important. Ohm meters are great, but they don't simulate the full load of the circuit, and don't give a clear measure of voltage drop in the circuit. There was obviously a massive voltage drop across the contactor, but it wasn't something the continuity tester flagged. Good video, for sure. I deal with AC systems, but in the automotive repair field. Still, there are some similarities as far as basic diagnosis. Enjoying these industrial AC videos. Very informative, with great diagnostic tips.

[@josephwright8002]

when you have screwy voltages with the contactor energized, consider that you may be getting a reading coming back from the compressor. pull off the compressor wires and see if the reading changes.

[@stevenmcl1]

I don't know if you want to do this, but what would be cool to see are timeframes. Like labelling what time it is when you're recording or just how many hours it's been as you've continued working on it. Gives an average on how long services typically take from an experienced technician. That'd be awesome for me as a new guy to set a standard for myself to meet and improve my efficiency.

It is definitely a series of capillary tubes which are fixed usually crushed or pinched tubes. Pistons move back and forth as refrigerant flow changes direction usually in heat pumps.

Just a side note, been using the fieldpiece probes, all of them for a few years now, you only have to sand before putting pipe clamps on if the pipe is real bad with buildup of some sort, or painted obviously. But if it's just tarnished, no need to sand. I will just put the clamp on and move it back n forth like 6 times and it makes its own little cleaned off marks on the pipe. Works great

[@ask4george1]

My first run in with a double row condensing coil, when I was an apprentice was a 15 ton Trane package unit, at a commercial printing business. I had hi condensing pressure. I washed the coil several times, and still had the same high pressure. Like you, I removed the top and saw the double coil. I split the coil and the inside was full of paper pulp, it looked like a laundry lint trap completely plugged.

[@rossy9549]

[@Fryloc87HVAC]

i just call it a fixed metering device. either expansion valve or fixed via cap tube, piston, etc. great vid Chris!

[@matthewmears5549]

The only thing I’d add is on the contactor, you could have verified the contactor as being bad by checking voltage across the contacts. So, you’d check voltage from L1 (line) to L1 (load). If you read any voltage over about 2 or 3 on the same leg leg like that, you should change the contactor. Also, when you read the ohms across the contacts, anything over 1 ohm should indicate an issue. That one read above thirty. Good going on this one homie!

[@TechnicalLee]

I was going to say the same thing-check the voltage drop across the contacts on each phase. It's a much more accurate way of determining the connection quality vs. ohm measurements. It might take as little as 0.2 ohms resistance to start causing low voltage problems on some circuits, and 0.2 ohms is within the noise/fluctuation of most meters, whereas most will measure fractions of a volt easily. If the voltage drop is more than a volt or two I would think about replacing the contacts. If you are running 25 amps through with a 1 volt drop that means the contacts have to dissipate 25W of heat, so it adds up quickly.

[@tomorichard]

I think he could be sure the contactor was faulty due to the voltage readings difference from supply to load
