This was a late evening walk in freezer service call that had an interesting defrost issue.

  1. JM SometimeWoodWorker says:

    Quit often machinery will develop a temporary fault that clears itself given a little time. So not calling as soon as there is a problem is often the best approach. I don’t say that this is best for refrigerant but it will partly explain why you don’t get immediate calls, not to mention that if they are crazy busy a service call may get a lower priority.

  2. DashCamAndy says:

    I'm fairly comfortable in saying that poorly-crimped wire was the problem, and that the unit iced up simply because the heaters never got powered. You wouldn't have an arc from high amperage if it pulled far enough out of the terminal to be fully-disconnected. Would the "brain" notice this, or is it a simple "dumb-logic" on-off circuit?

  3. ForceablePizza says:

    i know you probably won't admit it, but i say you are the best, not because you know everything, but because you don't know everything, and you know you don't know everything. when you make mistakes, you own them, and you put them them in the videos for others to learn from. and you are giving your knowledge out for free and asking virtually nothing in return. yes, you are the best. i'd rather hire you to work on something that i know you've never seen before than i had hire someone who deals with it on a daily basis because i know that you will figure it out, you will fix it, and it'll be right. i can't trust the guy that does it everyday to do that, that's just the world we live in these days.

  4. Jeremy Chapman says:

    Not that it has anything to do with the price of beans in China, but latex gloves always freaked me out while working around live power. Slip and melt the glove to your skin? Lol Great work as usual. I’m keeping your home town taken care of until you leave Cali!

  5. Jeff Jackson says:

    Not in Refrigeration. I. T. but operate by the same principle. 60k foot view, same as you, took me to where i am today as well, you are so so right. BIG PICTURE…. salute.. nice work

  6. The Dane says:

    Hi chris. a tip. Dont insulate the drain and let the drain heat run all the time.
    Connect drain heater to defrost heaters, and run it together, no insulation on drain pipe. Works best.
    also door switch which disconnect fans and solenoid.
    Good find with the wire.
    Other tip , i know the frustation. but i tell myself. they pay my overtime and im gonna take my time , and enjoy my work. Get into that mindset _D

  7. K Z says:

    i see that you test amp on heater and i dont think low amp is heating coils and i have seen few electric heater burn out after amp dropped to 0 other still 2 amp

  8. Richard Howlin says:

    Have you ever got to a freezer and it's so badly iced up that you just tell them to empty it and I'll be back tomorrow? Great videos, I hear your voice in my head sometimes when I'm working, " big picture "

  9. Mason Goodman says:

    I’m always rolling up my hose with a rag in hand so it’s not dirty. Glad to see I’m not the only one doing that. But I got hired on as a refrigeration and air conditioning tech for a company. Any tips for the switch from resi to commercial?

  10. Randal Richter says:

    Hi Chris, in a situation like this, bungee cords would work wonders on holding the motors, so you are not putting too much strain on the wires. Just a thought. Great video as always. I'm not in the industry but I love learning about new things. Keep up the great work!
    Hello from Wisconsin!

  11. Mr Sentinel says:

    As a customer, sometimes we give those late calls because #1 were not sure if the equipment is actually going bad or not until more than a day passes by with the same symptoms and #2 we have so much other stuff to do that we forget to check again.

  12. Glenn Sepelak says:

    I have been looking for a small leak forever on this system. walk in cooler takes 8 or 10 months to warm up. found the leak at the TXV 1/4" Bypass tube where the brass tube goes into the brass valve noe the braze joint micro bubbles after a long wait and small beeps from leak detector.. it was a Major pain in my a**.

  13. David Lee says:

    After working in multiple kitchens over the years, and seeing different Walk-ins. watching your videos really gives me some perspective on which kitchens really look after their stuff. Most kitchens with constant walk-in problems was due to defrosting problems and the tech they sent never took this level of attention and detail to do this level of work you provide. Dude you are awesome. Looking to solve the next one on my own hopefully lol. Great videos man.

  14. shine says:

    Great video my west coast utube friend! I'm in Philly n I'm not looking forward to another winter. They absolutely blow as u get older. Snow was fun when u got off from school but working n driving in it is no fun. I don't mind so much except for the rookies out on the road concern me. Stay safe n positive 🙏

  15. nsboost says:

    I have a big tote I toss under the evap to catch any drippings.

    Could you touch more on what goes through your head when your looking at a frosted/frozen coil? Like TXV frozen – low refer/bad TXV… or top frozen bottom isn’t… etc etc. I know nothings means this or that is definitely the issue till you inspect stuff. But what does the look of the frost tell you to check first?

    Thanks Chris!

  16. Shawn Lindstrom says:

    I don't do AC, but I've been watching all of your videos for months. What I love the most is that you keep it real, make mistakes and own them, and alwasy strive to do better. I do the same with my work. That is all we can do. Keep striving. Keep learning and improving. And, doing all that while maintaining a positive attitude and outlook despite work and life's many frustrations. Thanks for doing what you do.

  17. Brian Freeman says:

    I just wish chris was my boss back in the 90s. As I would have gotten better training as a newbie back then. Today , I have gotten back in the field . I was given door back in 2009 and I am happy that I was given a chance to get back in the field this year. Boy, do I have alot to catch up on.
