- Now lets take a look at the reversing valve!
How does a reversing valve work?
What does the inside of a reversing valve look like?
What causes them to fail?
What does cooling activated mean?
What does heating activated mean?
We will not be doing any diagnosing or replacing in this video but we will in future videos!
This is the best explanation and demonstration of how a heat pump reversing valve operates...thank you so much for taking the time to prepare and upload this video!
Amazing Instructor. Because of you I will not fail learning the reversing valve.
I used your magnet method to find where my valve was located. It was right in the middle and stuck. A manual I found suggested applying a high-power magnet to pull the valve to one side or the other. It did not move anything, but it must have loosened it a bit. When I turned the system on with the fridge magnet still attached, I watched it slide to one side. My system is working now. Thank you very much for your video.
Revasrs val not working canced drait fixing
Thank you for the time and effort you give to those who want to learn!!!
😁 I appreciate that!
Love the little hand. LOL
Excellent explanation as always Ty! Your way of teaching gives me another way to break it down for my apprentices and help them along their way to becoming a journeyman.
Cheers from Ontario, Canada!
Thanks Johnny! I really appreciate that!
Man, that’s the best reversing valve video I’ve ever seen.
I always “kinda understood” them, but never really worked with them.
Now I totally get it, and I love the magnet method.
thanks man, im 18 in trade school learning HVAC, this is my last year, really hope this works out for me when i graduate!
so great to get in young. remember there are all kinds of employers and alllll kinds of job possibilities.
Thank you so much for your videos and explanations. I have really really enjoyed listening to the way you explain different things. You have become my absolute favorite yt instructor. I cannot thank you enough.
Thank you, that really makes my day!
You’re the best. Thank you so much for this valuable information.
Thank you sir you explain the reverse cycle valve very nicely it very helpful for all hvac workers
Thanks once again 🎉
Wow..I learned so much from this video Ty..
Thank you sir 🤝
Thank you! I'm glad it helps
Great demonstration and explanation. I just started training a week ago and it’s so much new information. I’ve had to rewind just the beginning of the video like 6 times already so I wished he would talk a little bit slower lol it’s like listening to a auctioneer
Great videos they have always helped me grasp a better understanding at what Im looking at. Thanks for all time and detication you put towards these training videos.
Wow! Nothing to say but a big thanks to you. Great video !
Demystified it in seconds... awesome teaching skills.
Thank you!
Awesome video and thorough breakdown of the reversing valve!
Thank you!
Great video, love the tiny hand.
THANKS!
When I saw those tiny hands, my wife was like what are you going to do with those? Well today was the day 😂
love your explanation ty, it's clear and straightforward I'm hvac student here in the Philippines. pardon for my English I'm not very fluent. your better in our teacher. hahaha 😀
😂that little hand is the key
U r the man!
Well done as always sir🤝 Thank you!

Wow. Lot of work on this video. Thank you for making it understandable
Glad it was helpful!
thaks I allways wanted to know this. I hear a growel every spring.
Really very good video thanks a lot for your efforts.
awesome video! Thank you sir!
Thanks for the explanation ❤❤
Excellent presentation!
Thank you kindly!
Great Class…. Wish you were my instructor 👍🏾
Amazing. Thank you so very much.
big like for apprentice little hand
Excellent job
Thank you! Cheers!
Great video and explanation.
Thank you!
Thank God. Blessed you.
Thank you, sir.
Today’s lesson is brought to you by the sound WOOSH and BRRRRRRRRRRR.
Wouuuu excellent 🙏👌
EXCELLENT! Thank you
Thanks!
One way I remembered which is discharge and which is suction is the the middle (suction) line has “friends” it’s cool. The lonely one doesn’t it’s “mad” (red)
I like it!
Great video Ty, thanks much. Question: Are the typical line sets (3/8" high and 7/8" low) properly designed to handle the pressure differentials caused by the reversing valve in order to prevent premature rupture failures?
Love the video.I just did a service call yesterday,with a scroll compressor in a lennox heat pump, pressures are equalized while compressor is running.Im returning monday with a new compressor,it is under warranty.Im beginning to wonder is it possible its the reversing valve stuck in between.RLA of the compressor is 21.5,but only drawing 5.4.Discharge line temperature from the compressor is outdoor ambient,with absolutely no pressure change.Compressor sounds very nirmal at startup,but does no pumping.
Hey MR.Ty
Do you hire ? 😂
Thank you Sir
Good
Valve the same for HOT Gas defrost for you refrigeration nerds. AI find these on the MAC units at McDs a lot.
Hi Ty! Could you show how the Mollier diagram its changing for some particular cases? (e.g. low in charge, evaporator obtracion,..). Thx
Yes!
When I get to the advanced red class I will be doing a lot with the Mollier diagram.
Work keeps getting in the way of making videos
Fuck, you are an amazing teacher.
Most Asian mfg build their HP with reversing valves active heat configuration. In North America the convention is to do the contrary, reversing valve active cool. The rationale behind this is that is more critical to have heat in winter than ac in summer. At one point this was a requirement but It appears that with the influx of imported equipment some of the traditional NA design conventions are changing.
It depends on what the equipment is doing. Most heat pumps energize in cooling. And yes for that reason. Rev Chillers energize in heating mode
Great vid Ty, but, you cannot install the changeover valve in a position where the sliding piston is parallel with gravity, this is a no no no go
Parallel or perpendicular?
I have only seen them parallel, perpendicular is a no go because the oil will fill up the ends and not allow it to shift I thought I covered that, but I don't remember.
@@love2hvac We are on the same page Ty, but expressing differently, I meant a no go when the piston is positioned vertically, up down motion (parallel to gravity not to earth). Btw I love all your videos bcz you are thorough
Thanks, And thank you for clarifying. I see exactly what you mean now.
@@love2hvac now I’m totally confused. Forget about gravity and just use the ground surface. Should the sliding valve be horizontal or vertical? In the video where you’re demonstrating a real valve functioning the sliding piston is horizontal.
Never mind, you covered it at the end of the video quite clearly.
Honeyyy, I shrunk my hand!!! 😄...
Like the little hand pointer ... where u get it?
A place in San Angelo Texas called Eggemeyers general store
Sometimes I pinch it squeeze with ajustable plyers to eliminate it incase of it gets mulfunctioned , instead of heat extract it, pinch it from both sides, what u think?
Thanks.
I mean keep it on cool mode.
The valve very rarely fails but often gets misdiagnosed.
Damaging a good part eliminating 1/2 of the system function Incase a very very rare problem occurs sounds like a bad idea.
I had a faulty reversing valve on a 3T 17 year old R22 Rheem unit. It was stuck in heating mode - summer time in Georgia!
The solenoid would click when I cycled power to it. The valve would not change. The replacement part was not available and I recommended changing the entire system due to the cost and the age. To get the owner by, I crimped the end tubing, vented the end to get it into cooling mode, used a pair of Vise-Grip pliers to lock the slide in place and then sealed the tubing. It ran without any problems. This was the only time that I have had one fail.
I had considered cutting the reversing valve out and making it a straight AC - the cost would have been high due to the R22
so the weeme tube makes the slide valve valve move. 24 volts; where is it where n do power to the valve go again, clean line when brazing. with nitrogen or it gets dirty and then sticks; wow im in florida
On the demo condenser it looked like the the high pressures port was offset to the left. Do the three on top stay the Same with suction in the middle?
Yes
So, do most reversing valve default to heating mode, until orange wire is energized?
Is white wire energized at same time as orange, or simply until heat strips are energized?
So Mr Ty if I want to get my Certification through your classes is that Possible and if so; how much is the Class and Will you help me get my HVAC-R 608 REF ?
I have a video on how to get your EPA under the playlist learn HVAC.
I don't have a course to take it's just how I teach class when I do. I'm not with a school currently.
I recommend hvacr.elearn.network/
You can take an EPA prep class and take the EPA test remotely with them.
Thank you Mr Ty another Question Do I need a Class for HVAC EPA Certification? Or Can I just take the test I Actually Work in the Maintenance Tech Field and I am Looking to get my EPA CERTIFICATION AND HVAC-R CERTIFICATION
The EPA 608 is the only certification.
Schools can give you a certificate of attendance, and some can give a diploma but it does not mean much unless you get an associates from a community college.
You have to be careful, a lot of for profit schools are saddling people with debt but they give the exact same EPA 608 certification.
What the hell did he build
Just came across this short video from 5 yrs ago that found a melted teflon seal. The seal had formed so the valve worked in heat but failed in cool
Trane reversing Valve won't cool but heats ok.

Thanks for sharing! That's interesting!
It wasn’t TY it was the one armed man ✋🏻
😂
I’ve only seen 1 actually bad. In 12 years.
Yes! They rarely fail but often condemned.
