Question about Sub-Zero 632 / S

2 Answers

SubZero 532 have a subzero 532 that has developer a very small hole in the capillary line for the freezer. This happened due to vibration against a adjoining line. Can I braise this line and recharge or will I need to replace the whole capillary? The line is about 3/16 OD I do have acetylene and silver rods. Thanks Cliff

Re: SubZero 532

In refer. repair we usually us silver solder as there is a tremendous amount of pressure that builds up in your sealed system. You would use the same size copper tubing, 3/16", and flare the ends to repair. If you have experience and can get ahold of some silver solder that would be okay. (Silver solder is not the color but the type of solder to use.)

Re: SubZero 532

It's a bit more complicated than you may think. It's not good to braise a hole you need to take a 6 inch piece and splice it into the area of the hole. As for recharging if you have never done it don't attempt it. Since there was a hole you may have gotten contaminants into the line and contaminated or burnt the system. For one thing you need to be certified as it is against the law to open up a system and discharge it into the air. The old freon is poisoness to small animals and if you don't have the right equipment you can't do it anyhow. Also depending on how old the system it may take R12 or R134. It's not just a matter of pouring new freon into the system. It has to be evacuated and the old freon captured then it has to be measured then with the right equipment pushed back into the system. Like I said if you have never done it don't even try it you could make things worse.

Subzero 532 refridge cooling but freezer won't freeze

Unit has separate compressors and thermostat's. Clean the condenser, if it doesn't improve call for service, as there is a decent chance you will need sealed system work or defrost issue. If you need instructions on cleaning the condenser check try advanceing the defrost timer as they mostly die in the defrost cycle. Behind the grille there will be a panel with a small hole in it with a screw above and below. Use a flat blde screw driver to turn the gray piece in th small hole clockwise a few clicks. If the freezer comes back on you will need to replace the defrost timer.

SubZero 532 frig lights out

There are two door switches one for fan and the other for the lights. With the compressor running, there are two so yu need to make sure it is the refrigerator and not the freezer, open the door and press the right switch and listen for a fan. The left should be your light switch and the problem is generally in the switch, on rare occasions there is a failure of bi-metal safety switch part number 4200850. One very rare occasions you may have a wiring proble.If you go to there is a showroom locator tab on the top right corner, click it and you will go to a locator page which will get you to your local parts didtributor.

Sub zero 532: noise increasing.

We have the same SubZero unit and the water leak is the ice maker line or the pan that catches condensation. If you unscrew the panel at the bottom, you will be able to take the pan out and see if the water is from there. If it is from the ice maker line (which was plastic on ours), you should fix this right away as we didn't and we ended up having a $10,000 flood that ruined our hardwood floors. Also, the increased motor noise happened to us as well, but when we had the motor replaced, it is not much quieter.

Subzero 611 Refrigerator not cooling, freezer fine

It sounds like a defective ref section evaporator. This is common, due to poor quality metal used in fabrication. If you call subzero, they will more than likely fix it as they are aware of this issue. It probably wont cost you anything if you get them involved.
