- True T-23F reach-in freezer is very loud at startup. I check the pressures, amp draw and test the valves in a pump-down. See what was the final conclusion.

Looking forward to the video brother you do great work and your production quality has only gone up and up so glad that you came back to us after the whole NW. thing .you are definitely an asset to the hvacr world brother please don’t stop !!!!
Thanks man, I don't think I'm anything special, I just like reading the comments 😁. The things I point out are usually things I use to not know or stuff that I seen done wrong over the years.
I like the way you eliminate all other problems to pinpoint the exact cause. Well done
Everyday I'm shuffling. 🎶🎵🎶🎵 Thanks Mark!
Good job Rick. Your trouble shooting skills are improving.
Thanks man! is that kinda like I "you suck but not so much today as yesterday" 🤣👍👍
@@HVACRSurvival what else are you supposed to do when the customer doesn't want to spend money and wants the labor discounted or free. Ya know?
You have natural talent for the HVACR skills.
@@johnwalker890 your to kind, I just love doing what I do. It makes me feel good to hear I'm helping others👍👍
@@HVACRSurvival sometimes I understand what your doing and sometimes your doing things I don't until you explain or I lose focus on what the hell is he doing now.
Good video! My company rushes us too much to let us have enough time to get a good confident diagnosis. Nice work!
Thanks Justin👍👍I can't complain, I work for a great company and we got our previous dispatcher back so that will help with call scheduling.
Thorough steps and constant re-checks to stay sure in the dyagnosis. Not always possible in dubious companies in a constant rush (I quited a couple for that reason). Good one Rick, thanks for share 👍
Very nice sir, Wait all options exhausted all methodologies I would love to have someone like you work on my devices knowing that you’ve given and exhausted all options of repair
Thanks M-Dub, I try to fix it like it was mine. To me it's like a repair game. If I fix it then I win.
That reach in is in amazing shape from what i've seen and super clean. They sure do take good care of it but it's too bad it ate another compressor.
It was at a church so it didn't get used much.
Great video man- thanks for the plug at the end
No problem northern brother! Thanks 4 watching. Hopefully I can get some good stuff to video, things have been sporadic lately.
Thorough Diagnostic is the only correct way👍
It's interesting as I got a comment from one person that said why did I waste so much time. LOL I love people
I have a pop freezer with a similar symptoms... but it takes time to pull down... gonna hook up a CPR most semi hermetic have em' installed... but weird part it gets the gremlins after cool gas defrost...
great problem solving pratices. I will get better as a tech watching your video 2 thumbs up!
Your too kind! Thank you!
When I hear it only on the start up, I think starting circuit check, caps and current relay or potential relay. Ohm the windings... It almost sounds like it has no oil. It’s a pain but dumping the oil and installing a fresh charge measured amount of oil may be the answer. The with that shit pull down.... when I went to college for this in the 90s, they 5aught us it should pull down to a min of 16” in 5 minutes and hold it for 2. If the oil is saturated with refrigerant, it might boil off and the pressure rise would fool ya. The only thing I thought was, what if the service valve won’t front seat tightly......
Finally what's wrong with this system ? Did you replace new compressor ? Great video in HD. Thank you for sharing ^_^
I recorded this probably two months ago and I have not gone back to replace the compressor yet. In theory my feelings are let it run until it pukes then do a clean up. Why waste the money sooner than you need to. They must have felt the same way🤷♂️ . Far as what's wrong with it, I would say the valves are the issue because as you seen it will not pump down as far as it should. Thanks 4 watching 👍👍
How loud is it when not broken? Too loud for home use?
No it's fairly normal to a residential system.
Did you just zip tie the magnet to the amprobe or how did you secure the magnet??
Correct, I used the magnet that you'll see from a Fluke meter but you can also pick generic ones from Amazon, I used a wire tie around the meter then used a little micro Velcro to attach the magnet to the wire tie.
@@HVACRSurvival rad! Thanks! Just picked up the AMP 320 to go into my TPLC. I knew I’d seen someone zip tie the magnet, it was you! Appreciate your time. Keep pumping out great content
@@jmalmy2068 thanks man!
Great entertainment and educational as well ...
Thanks Eddy!
Another great video 👍👍👍
Thanks Harry👍👍
Boy, I’m experiencing the same issue and my assumptions about the compressor were true. Sounds like I’ll be either swapping it or ordering a new freezer.
Yeah, if you check everything else then that's about the only thing it can be.
+HVAC*R Thanks for the video. You're doing a great service to technicians and customers. Please kindly comment on my analysis below.
Higher current at start-up suggests higher load. The noise suggests flooded start. Compressor manufacturer analysis reports failure rate for replaced compressors 4x higher than original ones due to instalation errors.
The problem has to do with liquid refrigerant. Normally, during off-cycles the refrigerant collects in the coolest part of the system, i.e. evaporator. At start-up it should evaporate and return as pure gas to the compressor.
Is it possible that the new capillary tube has to do with the problem, i.e. too small a restriction due to improper capillary selection causes liquid to be carried to the compressor togeter with gas? Is it possible that some form of accumulator was removed during compressor replacement? Is it possible that it is not the evaporator which is the coolest place (e.g. due to de-frost heaters operating) and the refrigerant collects in the compresor body?
Your probably correct on all accounts. How long have you been in the field?
@@HVACRSurvival I'm mostly in electric installations. HVAC has a lot more diagnostic/repair and therefore offers a chance to do some thinking.
Videos from you and some other guys on the subject are invaluable and give YT platform a real value. Thanks.
@@Luzt. thanks man it's awfully nice of you to say. I'm just trying to help the next guy out. I still make mistakes everyday.
Nice find. So which valve was that? Looked like a king valve on the discharge side. Good to know about the CPR valve. Thanks my man. Keep up the great job.👍
That was the suction valve.
@@HVACRSurvival thanks1👍
Good job bro
Thanks bud👍👍
Does the amprobe do millivolts DC? What scale does it go down to for volts?
Dude, if the problem persists, you might want to consider a crank case heater and an accumulator.
I agree those items might help, according to the factory design, they didn't require any other items than what was on the machine. I truthfully would have preferred to replace the compressor and add a CPR valve CC heater but because this is used only every now and then, the church didn't approve any repairs.
Hi , great videos. quick question, i just installed a new compressor on a True t23f just like this one with the same compressor and it sounds loud at start just like this one did . Simce the compressor is brand new what could be my issue??
What was wrong with the old compressor.
First thank you for replying , Big fan!!
And the previous compress had a bad burnout, terminals "exploded" kind of burn out.
Current relay was welded on together and im pretty sure start winding was never disconected my thinking!
I flushed the WHOLE system with rx11 , tested it for acid and , came clean .
Capilary tube was on great shape.
condensor clean, condensor motor new.
i didnt check superhead or subcool! i just didnt how accurate it is since suction and liquid line are insulated together .
thanks
Please email me hvacrsurvival@gmail.com. It could be a couple things.
Cap tubes been replaced but is it the right size?
Head pressure would be higher and suction lower. It's worked since 2014 and just now got loud. I'd think there probably ok. Never know till you cut one and run a metal gauge in it and check with the factory.
It is the compressor at the first hear
Its not any louder than the 2000 lennox value series units that i discovered in the summer...
What application is that you have on your phone great video btw☺
I have the Tecumseh and Copeland app. Thanks👍👍
This refrigerator is from 1996, why didn’t they just replace it with a brand new one as it is likely going to become more difficult to repair and maintain as time goes on.
It's in a church and it only gets used at events here n there.
I doubt the new stuff is anywhere near as good for reliability
Are you going to recommend a cpr valve?
Factory said it did not have one originally so I don't know why it would need one now. It appears to me something went wrong in the compressor, if they choose to change the compressor which this has been a couple months ago I will check to make sure the accumulator is still up in the evaporator section. That's the only thing I thought of later.
Another thing to think about would be although the CPR would be beneficial, the compressor isn't pulling down to zero psi in a timely manner as it normally would. So damage has already been done to the compressor.
had an issue like this.discharge valves leaking back.when compressor wouuld cycle off,the condenser would equalize with low side of compressor outting liguid in crankcase.worked for a while but did have to replace compressor.new one ran much better.
How do you put a pressure tap on the system?
I think I showed it in a couple of my videos a while back. You can either put one of those junk saddle taps on there or braze one on like I try to do.
I think the valves are bad...Also wonder if all the oil is in the evaporator.
it's been about two months since I've been there, they haven't had us do any work yet. But if they do do it I will likely drain the oil out of the compressor to see how much is in the compressor compared to what it's rated for. Thanks for leaving feedback. I appreciate you watching.
Good job how long have you been doing HVAC?
Started residential HVAC and light commercial in 1995, got into refrigeration hard core in 2014, ice cream in 2016.
CPR valve what is that? Crank case pressure regulator.
You are correct. It regulates the return pressure to the compressor, you adjust it to the maximum rated load amps of the compressor during a harvest or initial pull down. It basically keeps the compressor from being overloaded and going off on thermal overload.
How do you tell how old a tecumseh compressor is
Appliances, HVAC & refrigeration try there app? I don’t do near as many Tecumseh as I do Copeland.
I tried using the app but it didn’t work is there a number on the serial number that says how old it is
@@SeansMechanical what's the model and serial numbe of the compressor?
Condenser looks dirty?
It wasn't spotless but it definitely was not impacted. I mentioned in the video that if we came back we will do a full-blown cleaning on it. I didn't want to spend any more time on it at that particular time because I didn't know if they wanted to fix it or junk it or just let it go.
Very nice vid , sir .
Hey just one thought that popped in my head : could that be an oil issue , like an oil filled evap where it wore out the compressor and the evap isn't making good heat transfer therefore not allowing the liquid to evaporate fully during start ups before it reaches the compressor ?
Just a thought , I'm probably talking out of my rear side though .
Cheers!
I would think my suction pressure would be low and that my subcooling would be high. But anything's possible.
I agree. Sounds like low on oil. I would add to your process 1oz of oil and look at current draw and noise duration. If it changes, RE-oil. Next, the cap tube is next to suction line. SubCooling is made complete by this. Since your cap tube is completely outside, that adds to your problem. Change out the cap tube with one a foot longer and put the loop in the freezer (-10deg) instead of in room (+72deg). Just my thoughts. Very good video!
WOW that's one noisy compressor
Yeah I was a little unreal when I first heard it.
which phone you are using
I record either with my note 9 or my GoPro Hero 7 black.
Wow, that is one clean box.. They don't exist like that around here... :-)
That was a kitchen that didn't get used very much. generally mine are not in that kind of condition either.
#146 thumbs up
Thanks Stevo!
First Hahahah finally
