    Leak Seal Repair

    How do you repair a perfectly good two door reach in refrigerator, that this stuff has been added to?
    Restaurant owner said that leak sealer had been added. The refrigerant (17oz.134a) had a sweet smell to it, and I don't know what brand or how much was put in.
    Found a restricted drier, replaced it. Now the cap tubes are stopped up.
    I don't want constant call backs on this unit due to restrictions or other malfuctions.

    I think I know what the fix is going to be, but would like to hear from someone who has faced this problem before.

    Where was the leak and is it still leaking? I personally wouldn't rely on that for a repair. Repair leak properly, flush system, change oil, replace cap tubes weigh in.new charge. Has compressor overheated?

    Not sure where the leak is. The thing iced over about 3 months ago. Thawed it out and it was working fine. (No auto defrost) Then yesterday no cool. I instructed owner to turn it off. When I got there compressor running a about 1 psi and the drier was frosting over. I am sure the compressor got hot running like that.

    drier frosting over sounds like moisture.

    For you to properly repair this piece of equipment now that sealant has been added. it would cost more than a new unit.

    That was my thinking.
    The condensing unit is on top of the refrigerator as well as the evaporator, which is enclosed in an insulated box.
    I was preparing to remove cap tubes, remove copper from condensing coil, remove suction line and change compressor.
    Flush the coils. Then replace the copper, drier and cap tubes.
    However I still don't know if this going to work. The sealer may harden up before I can flush it out.

    Well, the other option that I've heard is to remove the cap tubes and blow straight air through the rest of the lines.

    Since these sealers harden when exposed to moisture, air will carry enough moisture to harden all of the sealant.

    Then you can change the oil, replace the cap tubes and evacuate and charge the system.

    Changing the oil on the compressor might be a better first option than changing compressor. If it does not gum up the valves. (Recip)
