This was another iced up walk in cooler, I got the unit defrosted for the customer and on a follow up visit added a new defrost clock to get them by until we can repair the broken door and replace the equipment.

  1. What's happened here? says:

    Did that evaporator have 1 or 2 TXV's? The icing could be from the valve being open too far, or from a dud defrost element (unless the defrost is fan driven). And if the refrigeration system is all running smoothly it can often be where the warm humid air from the kitchen hits the coil first and condenses and freezes up. Air curtains can be really helpful with that

    All im saying is if 20degrees farenhite is -6 degrees celcius through a working evap coil….. I know at these Evap temps if you have a blocked Drain it will freeze watter as it removes heat in that water…. so coil will ice up during the process pluss opening and closing of door will make it worse….. So your LOL regardless……Any temp fom 0 degrees C to 32 F is freezing point….. It removeds heat where heat is present….. Evaps are like vacuume cleaners….They vaccume what is present……But heat is mosst in evap coils. If a coil is fully iced up it is a multidude of problems…. But it can be obviouse….. Every Refrigerant has its own state of absorption…..R 22 is pretty good…. But im finding more in refined refrigerants…… Regardless. So i guess you can comment LOL! Only my opinion in my experience.

    If it is a Freezer/Low Temp……..Then a heating element is present…… If its a medium temp/ Cool Room … No heater shoul be present……then that Drain looks iced up too me… Ive seen coils fully iced up but drain clear….. But i have also seen Dfully iced up coils with Drains fully iced up… If drains in a cool room is fully iced up with evap coils….. I know that drain blockage is present…….If coil is fully iced up only…… Then Humity is present….. Still do your checks regardless…. I always Knock on the drain pan to feel if it is hollow or solid…… That tels me the story.

    Can I ask ask you something? Ok first off one half of evaporator was frozen… ok but then again that txv looked to be restricted if I’m not mistaken. And compressor as you mentioned might not be in good shape. But, yet you put a new defrost clock on it,. And yet you said it could be cause customer was opening door to much, now what I would like to know is why the condenser and evaporator have to be replaced when it could possibly be a leak, or just bad compressor, or instruct customers to not try not to keep opening door which lets moisture in n could clog evaporator? If you would not mind if you can describe the details and why, and how it lead to you thinking it need a whole new unit??? Unless there was a leak in the low side somewhere, or compressor is getting bad, I just want to know, if you didn’t take proper superheat, is that what made you say, this unit is in bad condition we have to replace it. If you don’t mine can you elaborate on that good intelligent sir. Im in no way smart or as experience as you that’s why I want to have a clear explanation in case it happens to me, cause I’m a newbie on this trade would really appreciate it if you can share your knowledge. Thank you for making these videos you are very gifted no doubt. Like your videos really do, you know so much I want to be like you someday sorry if I sound corney

    What city is your business located? I watch your videos and appreciate the quality work that you do. We have restaurants all over the country and would love to have you out if we have any near you for service.

    Ahh i miss old contactors. Back when they were made with real metal and oversized contacts. You could pull far in excess of their rated load before any issues. Now they are made so cheaply with thin contacts and rubbish metal.

  8. More350Power says:

    I have two of those contactors….. one was about 30 years old when removed from service, still works…. It amazes me when I see some of the old compressor rooms with old equipment still running. Always enjoy your videos, have a great weekend !

  9. Brett Waechter says:

    Dude, unreal detail in your videos. I watch each one multple times… usually wake up with HVACR VIDEOS blaring away on the tv, lol. For apprentices, like myself, these videos are invaluable. Thank you so much for taking time to record, edit and upload these

  10. Ed says:

    Don't know if you noticed but when you put the contactor cover on when it was live the contacts started arcing @5:48 but didn't think it would do that with the contactor was pulled in with pressure on the contacts.

    Offering to clean up the mess of water on a Sunday evening is amazing guy, I'll bet 95% of people would not do that. Now if you're the boss and you are making the 150- 200 or more dollars an hour( I have no idea what the charge is) then I could see that it wouldn't matter what time a day or week it is. It just shows your good work ethics. And yeah they don't make em like they used to. Thx for the video.
