Refrigeration Question
We have a commercial 3 door refrigerator that will not stay running. It has
gone through many compressors, including a brand new one last time. The accumulator/filter is plugged and there is black oil coming out of the line. This does not seem right. I know there needs to be oil in the lines, but I doubt it needs as much as was dripping out of the line and I question whether it should be black. Are my assumptions correct so far? My thought was to get the compressor replaced and find some solution to clean out the lines from the oil and dirt in them. I don't think that a vacuum pump will do the job of cleaning out all the oil and junk. Is there a solution (liquid cleaner to wash out the lines) available and where would I get it? |

Refrigeration Question
Does the oil leak out all the time, or just when the unit is
running? Does the oil smell like anything? For example, cherry pits, licorice, or asphalt driveway sealer? This will help us identify the problem. -- Christopher A.

Have you had anyone who knows about commercial refrigeration look at your refrigerator? There are several products used to clean out a system after a burnout and acid neutralizing filters should also be used on both the liquid and suction lines. GEEZ! Get someone other than Leroy The Fridge Repair Man to fix your box. TDD |

I would replace the refrigeration guy. The lines have to be as clean as possible. I think that acetone and compressed air should do the trick as far as cleaning is concerned. Prior to charging the system, they need to do a complete leak check and then pump down to works to remove all water that might be left in the system. -- Roger Shoaf About the time I had mastered getting the toothpaste back in the tube, then they come up with this striped stuff. |

To do a proper service, I'll have to tear it down and blow cleaner through it with dry nitrogen. I'll also have to drain the compressor and wash it out.

Refrigeration Question
If a hermetic compressor shorts out (electrical windings)
and burns up, it can decompose the refrigerant to other chemicals. As to dark oil, not likely. But in any case, the chemicals are still within the sealed system. They used to make acid absorbing filter driers, but those are also part of the sealed system. -- Christopher A. Young Learn more about Jesus www.lds.org .. "Roger Shoaf" wrote in message ...

It could be burned contacts on the clutch relay causing low voltage to the clutch coil or simply a sticking clutch. Of course, loose connections could be the culprit. The darn thing's schizo. TDD |

Ah, well. You'll get it by and by.
One customer of mine, fixing his walk in cooler. Anyhow, the AC didn't work on his big pickup truck, and the garage wanted several hundred dollars to fix it. I found two places where the wires were unhooked at junctions. Connect them back up, and the AC came back to life. -- Christopher A. Young Learn more about Jesus www.lds.org ..

Christopher, It appears from the original post that the system has been unsealed several times, so the original integrity of the system is suspect IMO. If the capacity of the acid absorbent in the dryer was less than the amount of acid that remained in the system after the several times the compressor had been changed, I would suspect that this might be the cause of the black oil. In the times that the unit had been serviced, someone may have also used the wrong oil or refrigerant, or perhaps recharged the system with contaminated refrigerant. Now that the system is open, it seems to me that all of the crud that may in fact be in the lines should be cleaned out so the unit can be returned to reliable service. Or you could be correct and the whole thing is a hoax. -- Roger Shoaf About the time I had mastered getting the toothpaste back in the tube, then they come up with this striped stuff. |

Most kinds of winding insulation have some carbon in them, and produce black soot if they burn. Black carbon in the oil means black oil, so black oil doesn't seem that unlikely if there's been a burnout. Dave |
