    LOL, no.

    Okay, I'll spill the beans.

    What you do is remove some refrigerant to get the subcooling down to a couple of degrees, if the drier is restricted, NOW you'll get a temp drop across the drier.

    Of course, that is the technique used when you don't have an access valve on both sides of the drier. Like most common package units, that only have a high side tap on the discharge of the compressor.

    You see, you could have a huge pressure drop across the drier, but if you also have enough subcooling, then there will be no temp drop across the drier until there is no subcooling.

    Pretty trippy, huh?

    If you were a real tech, you'd solder a relay on that board and call it good to go.

    I do a triple evac with nitro to remove non condensables.

    I use 56% silver on everything except steel.

    For what it is worth, I gave you the answer in the attached post, LOL.

    So, if you go behind someone who over charged the system because of low pressures, and you now have 45*F subcooling, you may never see a temp change.

    Next idea?

    See what I did there?

    Sometimes the answer to our question is right in front of us, shouting, but we can't see or hear it.

    So we need to step back, relax, and just let the unit talk to us.

    And the value of this forum. I screen-captured this additional info from a 'medic post. I tried to find it on the site, but couldn't (maybe it was lost in the crash). Anyway, here's the screenshot:

    Yup, I get lots of little nuggets here that help tie together all else that I know. Which helps me to be a more awesome tech.

    And in return, I am happy to help another who is trying to better themselves.

    That's the whole cycle of life.

    So your on a deserted island. Your survival depends on an elaborate solar refrigeration system. Don't ask why. The question is, what book would you want most to have?


    The answer is How To Build A Boat.

    Just an exercise in problem avoidance. Always good with a new job.

    I know...that's what made it ironically amusing to me.
    Is the Religious Right to blame for Christianity's decline?

    They argued that, as the Religious Right became increasingly visible and militant, it became associated with Christianity itself. And if being a Christian meant being associated with the likes of Jerry Falwell, many people—especially political moderates and liberals—decided to simply stop identifying as Christians altogether.

    If I was stranded on a desert island the book I would want is how to build a motor that would run on the available fuel. That's assuming I wanted to get off the island.

    I think I'd want to stay on the island. I'd only need the boat if it was discovered by others.

    No thanks...I have my own. You can pack an awful lot of world into a very short time if you failed to answer the knock some time before adolescence...

    Anyway - back to Fender's pending career; I'm regretting and repenting the sidebar.

Not to mention, the owner has been to the school and talked to us a few times but I get a strange vibe from him. He comes on really strong, too strong really. I have also seen a few reviews online from current and former employees that aren't that great. Of course you always have to take those with a grain of salt as it were.
    Ordinarily I would say jump right into a commercial refrigeration gig, assuming there would be adequate on the job training. However I seem to recall you are around my age - and that usually means physical challenges are right around the corner or already at hand. Lots of 28' ladders and hauling equipment up and down. It nearly killed me just doing light commercial with residential a few years back.

    OTOH, residential is becoming a real pain as well. Horrible on call stints, 13 hour days, absolutely unpredictable schedules year round, idiotic customers and occasionally filthy conditions. The technology is steadily becoming far more difficult as well - I often have no idea where to put my meter leads or what all those ones and zeros are supposed to be doing. It was all fairly simple just nine short years ago.

    Tough call. I guess it would depend on how well you are holding up physically - but you are nearly certain to get roughed up pretty good.

    I am blessed to be able to continue my work for now. I have good genes...my Dad just turned 100 on American Independence Day...sort of ironic for a Canuk born on the 4th or July...it is as if he was destined to come here and for me to be born in the cradle of liberty.

    I have a birthday in about 6 weeks. 67. I will be doing this as long as I can drag my stuff up onto the roof by ropes.
