Cooler is not cooling (R290)

[@kevingleason5434]

Love how you incorporate the charts into your videos. Nice touch.

[@REFRIGERATIONKITCHENEQTECH]

trying to shorten the learning curve for our techs, hoping this will be what I’ve been looking for.

[@RobertLanghorn]

I agree about the charts. I can tell you really understand this stuff. I'm training a new tech on residential appliances and we're starting to repair R600a systems soon.

[@REFRIGERATIONKITCHENEQTECH]

nice, I havnt seen that refrigerant on the commerical side yet.

[@RobertLanghorn]

@@REFRIGERATIONKITCHENEQTECH It's used in small residential appliances in European countries. Many US states are requiring new appliance sales not have high-GWP refrigerants starting January 1st, 2021. We are seeing a big push from manufacturers for LOKRING connections as well. They don't think we can safely braze around flammable refrigerants I guess.

[@REFRIGERATIONKITCHENEQTECH]

Intereting. I know Delfield was pushing us to buy their “lockring” type tool to repair their units.

[@kiweekeith]

Thanks for a Very Informative vidclip .... I am in NZ, Retired and I do some 'Fridgie' work for myself, to keep me busy .... I have just had virtually the Exact same Compressor, same make, and it also failed with the Very Same Symptoms .... The 'Standing Pressure' was fine .... When I removed the compressor, I tried to tip out the 'Oil', there was not even a Teaspoon of Oil in it, super Brown and Stank.... So the Compressor had intemittent 'Seizing' and the Amps had Exactly the same 'Draw Chacteristic' as in your Great vidclip .... Very Best to ALL, Thanks Again, cheers from Christhurch, New Zealand.

Thank you for you videos really appreciate it I feel more confident as a technician

[@kingkatiin2658]

Starting next week as a kitchen technician. This is gonna be a rough learning curve but you’ve already helped so much really appreciate your videos. Great work

[@REFRIGERATIONKITCHENEQTECH]

Good luck to you sir! It’s gonna be a long first year. Take your time, don’t take shortcuts and master schematics and you will dominate the industry.

​@@REFRIGERATIONKITCHENEQTECHI'm in Ontario Canada,my true vertical fridge soda cooler isn't cooling. Our technician added gas and charged it but said it still doesn't work. Told me to keep it running and if that doesn't work he said to just buy new one or get a free one from Coke and Pepsi. It's a 10 year plus unit. Compressor was working very hard and some.of out water will freeze as well. Especially the water bottles at the back. Any idea where to take action on this?

Thanks!

[@dougking7592]

This might not have anything in common with this compressor you sir replaced,but I have had every compressor that’s has been changed out (2 to 4) weeks I’m. back out looking for a dang leak in the evaporator may not mean anything just the way it seems to work with me

[@REFRIGERATIONKITCHENEQTECH]

Lol, thorough leak testing is important

[@ZeEnderCat777]

Thank you for your great videos. Still quite green in the trade and your charts and equations help a lot, as I did not go to trade school. So, after replacing the start components and you found that it didn't help, did you replace the compressor or just the filter drier?

[@ZeEnderCat777]

oh you obviously replaced the compressor because the old one is showing at 7:07. mb.

[@randomrazr]

what makeis that cooler. all stainless, dam looks pretty well made

[@CapsCup2012]

Any good resources for selecting capillary tubes for a system?

[@Lilyzhang-uy2rb]

Very nice video .

[@blingmotions6996]

Is the td temperature a set temp

[@hvac01453]

That’s funny, I do the same thing, replace those start components. They are usually bad. I was noting you didn’t invert the propane cylinder??? You charge vapor? I have the same scale as you. With that small a charge! I get skeptical on its accuracy with charges that small. If I zero the scale out with let’s say 2 pounds on it....if I come back 10 minutes later it’s changed by .7 ounces because I think it’s just a heated diode or spring that changes. To help stop this I acclimate my scale where I’m using it by removing it from the case and try do this at least 30 minutes before I need it.

[@REFRIGERATIONKITCHENEQTECH]

Yes, I don’t really trust that scale for the small charges unfortunately. Some of the other commentators on some of my videos told me about this new scale where the bottle screws into it and you charge it from there. The price was like under $150 I think so I’m going to most likely order one of those.

[@hvac01453]

@@REFRIGERATIONKITCHENEQTECH before you do... the max charge for maximum propane charge is just over 5 oz, the bottle can’t be more than 3 pounds so look for a cheap throw away scale that Max’s out at about 5 to 8 pounds. Then you’ll get better accuracy. If you have a new bottle of it, just weigh a full one then double the pounds. This should give you a good midrange on the scale. Less than 40 dollars I suspect. Use a cardboard container to support it upside down, then zero the scale.

[@REFRIGERATIONKITCHENEQTECH]

Yes we have those cardboard holders as well. We are going to start using the 1/4” hoses that just came out in our area as well. I’m curious to see how this new scale goes, the reviews from other techs has been really good.

[@babyking5763]

Cute chart you’ve got lol

[@terranceburgess9170]

I worked on one today it’s hard to tell if a 290 compressor is running

[@terranceburgess9170]

I have to go back I think the compressor is bad

[@navjotsingh-lr6nn]

Hello sir I am first year apprentice on video you said we need 36.3 psig but we are having 85 psig . But how it’s low please explain?

[@chaseme9860]

Where did you come up with the +30f for the head pressure calculation?

[@REFRIGERATIONKITCHENEQTECH]

Condensor split is usually 15 or 30F.

[@cesarvargas1758]

Did you swap out the compressor or just changed the filter?

[@REFRIGERATIONKITCHENEQTECH]

Compressor was no good

[@steveshirk7035]

How do you determine the TD for a given coil?

[@REFRIGERATIONKITCHENEQTECH]

Reach in 20F, walk in 10F

[@steveshirk7035]

And I assume Condensor is always 30F?

[@REFRIGERATIONKITCHENEQTECH]

lol no, most of the newer stuff is 15F split

[@hvacmaster96]

Have you changed the compressor?

[@REFRIGERATIONKITCHENEQTECH]

Yup

[@hvacmaster96]

@@REFRIGERATIONKITCHENEQTECH how then is the freezer pressure calculated where the desired temperature is 0F, 0-20F equals -20F which is very low

[@REFRIGERATIONKITCHENEQTECH]

Your evaporator coil needs to be colder than your box temp, or else we will never get to temp. In the case of reach ins, we want the refrigerant going through the evaporator coil to be 20F colder than our desisted box temp.

[@hvacmaster96]

@@REFRIGERATIONKITCHENEQTECH and okay and how much should be the desired temp of the minus freezer box, that is, to read the formula for calculating the suction pressure x-20F = x

[@REFRIGERATIONKITCHENEQTECH]

0F to -4F

[@JDT738126]

Hey I have a question, where did you get the value for the TD? Is that specced on the rating plate/decal? Just taking a guess but everything else makes sense

[@REFRIGERATIONKITCHENEQTECH]

Every manufacturer could be different, but generally a cap tube will have an evaporator TD of 20F. Condensers on these reach ins are usually a 30F condenser split, but I’ve seen it as low as 15F condenser split on some lesser known manufacturers. Unfortunately, this info is not on the nameplate.

[@JDT738126]

@@REFRIGERATIONKITCHENEQTECH hey thanks for the reply! One more question, does the length of the cap tube matter? I understand the idea is to restrict flow so I am guessing you should have a certain length on the tube.

[@REFRIGERATIONKITCHENEQTECH]

Yes length will matter. Too short and there will too much flow, too long and there won’t be enough flow. Now there have been instances where the cap tube is restricted and I’ll cut an inch or so off both ends, blow out with nitrogen and braze it back together.

[@JDT738126]

@@REFRIGERATIONKITCHENEQTECH if you have time I would love to see a video on how to properly select the right cap tube length. Thanks for sharing your thoughts
