im wondering if some freezers that don't have the defrost termination on them can be converted to a time clock that has defrost termination and wiring in a defrost termination klixon in the evaporator. as Paragon is a good mechanical time clock they have the electronic Paragon time clock but would stick with mechanical. newer supermarkets with rack systems have a computer controlling everything in the store. and mainly Walmart, their rack system uses heat reclaim for the water heaters to provide hot water to the store. , AC or Vise Versa.
good ol true.. not a great fan of them worked on two last week both had the same problem the plug in for the condenser unit Fry's out and don't how they don't catch fire ! thanks for great videos keep them coming
Did not remember watching or commenting on this video 3 years ago. Went to a call today, unit was partially disassembled, wire nuts and screws scattered about and could not figure out why the time clock was seemingly calling for refrigeration and defrost at the same time. Going back tomorrow with a wiring diagram and an eye for removing that brass bus bar on the timer!
even if there's a light it's gonna get ignored... i put a sticker on customers walk in and ice machine bin lid to remind them to keep it tightly closed and every time I'm doing pm there the door is cracked open and the ice bin lid is wide open.
ya, noted the tank wasn't inverted, no telling whats in the unit now, no big deal, pull down to 2PSI and charge it. yank the thermostat and install a new one. They are usually fixed cut in of 41F and the adjustable part is the cut out. Get it down to about 38 and slowly raise the set point till it cuts in to get a rough idea.
Benjamin Thorman i know u r from refrigeration line. when u answer deep frize or vc cooler is always tripping. by the way sir do you have what's up number.
man I just finished one of them true freezers today. I had to replace the fan delay/ defrost termination( it's one control. 2 in 1).. and the tough part with working on them is you can't get parts for them in Jersey. I found parts for them online only
Sir, I honor you. I have a comment. If there is a leak, then add refrigerant. But... if there is blockage then there will be oil migration. You had two block for heat transfer. Slugging? Refrigerant in oil? Oil in coils causing insulation to perfect heat transfer? I normally heat up the evaporator with a hair dryer for a couple hours to move that oil, then take readings as box temp falls to -10. Head pressure is key. Please advise....
Great example for the new guys.... even after checking the part number of the timer being the same, a rookie would have overlooked the brass bus bar and shorted it all out... that and the wire for wire one at at time change out. Newer guys who are cautious should be taking pictures on their phones before disconnecting anything. Wish you were still posting videos but respect your decision to stop. Be well sir!
i always thought of a head pressure sensor that makes a boxing glove come out of the side of unit and punches the customer every time they walk by.aA relay and a renco Hp control will do:)
My True freezer has three cond fans,and one fan shuts off . It gets over heated ,then only shuts the one fan. The freezer doesn't stay at right temp. I replaced the bad fan ,but it shuts off after five minutes . The other two fans run fine Any ideas ?
Nice work, those clocks i dont come across much here everything is digital even on the true refrigerators. Last one I saw those was on a walk in freezer from teh 70 ies, it had a pressure connection on it as a defrost termination control. Did you end up defrosting that evap? Always a pain in the a***. I did notice that the compressor on that freezer was a Aspera those are not the kind i did expect on a True. I would expect something better like a copeland or tecumseh
your right about putting a sensor on the condenser but true & beverage air can save alot of compressors by putting an hpc safety switch on the high side. 80% of those compressors fail because the condensers are plugged up. the mfg should spend the $5 for a hpc stem switch soldered into the high side to save them compressor failures or get a self cleaning condenser coil like turbo air has
+kingofthecrease30 I agree, but we'll probably never see them do that, back in the 70's I was waiting for Copeland to replace their cast iron compressors with cast aluminum, they would be light, ...thanks
hey jim one thing more I found how to dirty freezer condenser and looking the little restaurant small corner on this video no clinical health and safety no good management lol..?
Your right on the cleaning of the condenser, I looked at a True 1 door freezer were the compressor had failed due to constantly overheating. A sensor would be nice, at least an led light or something. Thanks again....
Just cause a defrost timer spins does not mean it is working correctly. I do commercial Refrigeration it could have bad contacts in it there are a multitude of issues it could be. Paragons are fairly simple now grasslin are a whole nother story
i love the way you explain the work you're doing and the reason why you do it a certain way! cheers from an hvac apprentice!
+Jean Claudine thanks
still important in 2019...a novice here...learning so much from you...thank you.
are TRUE fridges and freezers even worht buying?
I very much appreciate for posting these videos Jim , I'm learning a lot from it coming from a knowledgeable, unselfish guy like you.
I've learned a tremendous amount from you. Great stuff!!!!
I enjoy ur viedos. keeps me sharp on refrigeration
Amazing video!! Well done Jim!!! You are still my favorite!!!
Hey JimI really like your educational learning video . Thanks for sharing it and letting student learn what it is like in the field. Regards Sr.
Great work Jim, thanks for posting!
+Philip Dumond thanks
Great video very informative.
Felt like I was at work. Lol.
Missing your videos. Hope you will be posting again.
Another great Video Jim
thank you jim alway's looking forward to your excellent video's!!!
+jimbola77 thanks
Keep up the good work I love the video very helpful 👍

VERY GOOD VIDEO.THAKS
Nice! well done as usual!
+Marat RPM SoCal thanks
What should the low and high pressure be on a small reach in restaurant cooler
Hi Jim nice videos how and what type of sensor would you put on the condenser to alert for dirty filter
good work Jim. yes the good old 8145-20. I replaced 3 last week.
+George W good ole fun, thanks
good ol true.. not a great fan of them worked on two last week both had the same problem the plug in for the condenser unit Fry's out and don't how they don't catch fire ! thanks for great videos keep them coming
+Rick Hubner the rubber on the plug and wires are self extingusing, thanks
great video, thank you!

CO2 cheaper than nitrogen for blowing out the coils? Do you use a regulator? to what pressure? or just regulate it with the hand valve?
Are Migali 2 door refrigerators any good? I usually buy True brand. Thanks!
Good work Jim
+Harry Dickson thanks
Nice job Jim.
+RomTop Instal thanks
Sr. Petinati parabens pelo seu trabalho. e gostei do aparelho de controle muito pratico. abracos sao joao da boa vista - Sao Paulo BRASIL.
great video Jim..
+A&J Heating thanks
great video!
+refrigeration tech thanks
even if there's a light it's gonna get ignored... i put a sticker on customers walk in and ice machine bin lid to remind them to keep it tightly closed and every time I'm doing pm there the door is cracked open and the ice bin lid is wide open.
How did you slide out the condenser?
ya, noted the tank wasn't inverted, no telling whats in the unit now, no big deal, pull down to 2PSI and charge it. yank the thermostat and install a new one. They are usually fixed cut in of 41F and the adjustable part is the cut out. Get it down to about 38 and slowly raise the set point till it cuts in to get a rough idea.
great video from a great teacher with great explanations thank you
+gonz garr thanks
There is something satisfying about cleaning the condensers on those True units... It's like a lint filter or something
Benjamin Thorman r u a technicians of a refrigeration line
Bijoy Tudu I do a lot of maintenance work, I do refrigeration but it's only part of my job. it's a fascinating technology though.
Benjamin Thorman i know u r from refrigeration line. when u answer deep frize or vc cooler is always tripping. by the way sir do you have what's up number.
Condenser?
man I just finished one of them true freezers today. I had to replace the fan delay/ defrost termination( it's one control. 2 in 1)..
and the tough part with working on them is you can't get parts for them in Jersey. I found parts for them online only
+Ahmad Hamad I just order from Refrigeration Hardware I think they're in Colorado, thanks
+Jim Pettinato I order from parts town.
My fan in the freezer isn't moving, how can I fix that?

Be well sir!
I would like to use a strong dry/wet vacuum cleaner to suck the dirty layer first
i always thought of a head pressure sensor that makes a boxing glove come out of the side of unit and punches the customer every time they walk by.aA relay and a renco Hp control will do:)
Yea.says clean the condenser dummy. Lol
THAT IS THE PSI ON SUCCTION LINE OF COOLERS???
My True freezer has three cond fans,and one fan shuts off .
It gets over heated ,then only shuts the one fan.
The freezer doesn't stay at right temp.
I replaced the bad fan ,but it shuts off after five minutes . The other two fans run fine
Any ideas ?

+sjef oekel I remember those pressure defrost termination Paragon time clocks, thanks
nice job Mr Jimm !! but I have a question... how many amps sould have the heaters?
+frank esquivel There is a label / nameplate inside the cabinet with the amp information, thanks

where you bought the parts sir?
can u vacuum a condensor
hi Jim u work on that is a timer .
Are these 220 volts ..
hey jim one thing more I found how to dirty freezer condenser and looking the little restaurant small corner on this video no clinical health and safety no good management lol..?
+Arshad Mahmood It's a very old place, thanks
I wish Jim was still making new content.
Your right on the cleaning of the condenser, I looked at a True 1 door freezer were the compressor had failed

when he take the clock out of the box just go to TIME 20:05 WELCOME
25:25
I like this guys videos but haven't seen nothing new in a long. long time I was wondering did he croak or something..
Jim stopped making videos instead of dealing with idiot comments.
