Fixed my Adlor-Barbour Refrigerator.
After having repaired the leak in the tubing that joined the copper tubing from the compressor to the aluminum tubing from the evaporator with liberal usage of high-quality self-stick (no adhesive) rubber electrical tape, my refrigerator has been functioning normally for over a year. It's been doing a great job keeping my beer, wine and perishable produce fresh. But, just recently over the past month or so it has been acting up. It starts to compress and then acts like it is overloaded and the compressor runs faster and gets louder and the fan runs faster but the compression pretty much ceases to compress as evidenced by the voltage on the volt meter jumping up about a volt. Then it will cycle off and then back on and do the same thing over and over. Sometimes it will work for a minute, sometimes five minutes sometimes ten and then back to a minute. No rhyme or reason to it. Needless to say the box doesn't get as cold as it should be getting. Almost the same symptoms as would be the case if it had too much gas pressure to contend with. I checked the pressure of the refrigerant several time and it has remained at the correct specs. (at least there are no leaks) What next? I did notice that the spade connectors at the yellow (ground) and red (positive) leads to the control box unit got hot at times if I touched them. Arching perhaps and losing the required voltage to the rest of the unit so the diagnostic unit sensed low voltage and shut down the compressor? Maybe so. So I just turned it off at the breaker and pulled the spade connections. I squeezed the female spade connectors (on the wires) together a little tighter and plugged them back in. They slid on hard while they had slid off quite easy. Perhaps the vibration over the years wore the female and male spade connectors enough that they got loose and were commencing to arc and/or make a poor connection? At any rate, since I crimped the connectors tighter it hasn't missed a beat. I am just soooo freaking smart!!! Perhaps this might assist somebody else who has been experiencing the same or similar symptoms. -- Sir Gregory |

Granted, a proper, inboard diesel generator is mighty quite. A little splashing is about all one can hear and that's when there is no wind and wave action. The exhaust fumes, however, are the real problem. Why is it that those who run diesel generators always "treat" the entire downwind anchorage to their fumes? Why is it they can't be considerate of the safe breathing of those who are out there because they wish to breathe fresh air. Why can't they anchor DOWNWIND of everybody? Enquiring minds wish to know because the only answer I can ever come up with is it's because they are rude, inconsiderate, self-centered and couldn't care less what pollution they force other people to breathe. After all, the entire world is required to revolve around them and their desire to watch TV, run hair dryers, microwave ovens, air conditioning, etc. STAY THE **** HOME if you can't live without all that crap! -- Sir Gregory |

If a service technician can charge you and extra hour labor while he sits and twiddles his thumbs or smokes cigarettes he will do so. Here's basically how it works. A "decent" electric vacuum pump is capable of pulling down to about 200 microns. The pump comes equipped with the standard vacuum gauge, which in the U.S. is measuring inches of mercury vacuum. inHG. Not accurate enough to measure microns. It will be bottomed when there's still more vacuum to be had. But a decent micron measuring gauge cost twice as much as the evac pump. A good HVAC guy buys one. Typically refrigeration specs call for evac no higher than 500 microns. Since the evac pump has to work harder and takes longer to draw down those last microns, let's say from 10000 down to 500, but the inHG gauge needle has stopped moving, you let the pump run on for a while. It could take the pump 10 minutes to bottom the inHG gauge, and another half hour to actually reach 500 microns vacuum, which is what indicates an acceptable amount of moisture has been boiled off. Some people - like me - can "guess" by the sound of the pump when it has stopped pulling vacuum. But without an accurate micron gauge, it's really just guessing in the end. I usually end up letting the pump run about 5-10 minutes after both the gauge is bottomed and there's no tonal sound difference from the pump. But without the micron gauge, it's voodoo anyway. I don't sweat it. I've read that pros with micron gauges sometimes have to run the pump for hours to get down to 500 microns. I can buy that. In the past I've repaired my R-12 auto A/C's with no evac, and run them for years after. I started maintaining family cars with R134 some years ago, and wanted to treat them better than I did my old cars. So since one of my kids is a mech and they had an air-operated vacuum pump in his garage, I had him do evacs at work a couple times. That was a hassle for him and me because of timing. So I looked into buying a vacuum pump. First thing I found is air operated vacuum pumps are plain incapable of achieving 500 micron vacuum. Lucky to even reach 2000 microns. And that's with a high capacity air compressor running a looong time. So I bought a mid-level Mastercool electric. About 120 bucks and about 30 for a couple quarts of oil, which is important maintenance on a vacuum pump. Now the other main part is about maintaining vacuum. That doesn't require running the pump, but does require time. I usually let the system set for 2-8 hours with the pump off and isolated when I'm done pulling vacuum and before I charge. Depends on how lucky I feel. That's to see if the system has a leak. Again, that's mostly voodoo without a micron gauge hooked up. The last time I maintained vacuum on the inHG for a couple hours, after replacing the compressor and dryer, Gauge never moved. I still lost R134 from a very small condenser leak, and a year later the car stopped cooling. Supposedly a micron gauge would have picked up that leak because of its sensitivity. But I might be wrong about that, and the condenser wasn't leaking when I tested leakdown. No way for me to prove the timing of events. Anyway, having your own electric evac pump and a gauge set is a good idea for the DIY car or boat guy. Inexpensive enough to pay off the investment. A micron gauge is kinda stretching it, and I don't plan on buying one. I don't mind a little voodoo. |

So, bottom line, the real reason to pull a vacuum for so long is: 1) subpar equipment that takes forever to get to specs 2) to check for leaks So, it follows, then, if one knows there are no leaks and one has a decent pump that can quickly pull the correct vacuum then one minute is as good as one hour. -- Sir Gregory |

They don't take forever. Mine takes about 5-10 minutes max to bottom the gauge on a typical car. Then I run it another 5-10 minutes to boil off more moisture and get a lower micron count. But it's just guessing without the micron gauge. 2) to check for leaks So, it follows, then, if one knows there are no leaks and one has a decent pump that can quickly pull the correct vacuum then one minute is as good as one hour. If you don't have a micron gauge, you don't know if you've reached the "correct" vacuum. I'd guess you'll get better results lowering microns by running the pump a while after the typical inHG gauge bottoms out. No idea about long term impact, but specs typically want it down to 500 microns. I've also read that going below 200 microns will start boiling off the compressor oil. Bottom line is without a micron gauge, it's voodoo. Bottoming the inHG gauge, then running 5-10 minutes more is just how I arrange the chicken bones. Seems to work. |

As many water molecules will be drawn out in a vacuum held for one minute as for one hour. American's also believe in ripping off the customer. If a service technician can charge you and extra hour labor while he sits and twiddles his thumbs or smokes cigarettes he will do so. Your concept of physics is seriously flawed. Firstly, your term vacuum is not a very scientific one as there is essentially no such thing - it is rather a lower then atmospheric pressure and it doesn't "draw out molecules", rather as pressure is reduced water boils (is vaporized) at a lower temperature which allows any water to "evaporate" and can easily be removed from the system by flowing toward the low pressure source. Now; all vacuum pumps vary in efficiency and none of them is capable of "pulling a complete vacuum" and as it takes time to completely vaporize any water in the system, theoretically the longer one keeps the vacuum pump running the more likely one is to evaporate all the water in the system and remove it. Next flaw in your argument: "American's also believe in ripping off the customer". While I can't argue with your supposition I can say that you have never been ripped off compared to what will happen to you when you arrive in one of these 3rd world, developing countries. As soon as they see you they will identify you as a foreigner and everyone knows that all foreigners are rich, so prices go up. I've seen tourists, at Patong Bay on Phuket Island, paying double the price for a colorful tee shirt that the identical tee shirt sells for in Phuket Town, some 15 Km away. And a bus ride from Patong to Phuket town costs less then a dollar). -- Cheers, Bruce |

Respecting drawing a vacuum in a refrigeration system, it can't possibly matter how long the vacuum is in place. One minute is as good as one hour. In a vacuum one draws out molecules. As many water molecules will be drawn out in a vacuum held for one minute as for one hour. American's also believe in ripping off the customer. If a service technician can charge you and extra hour labor while he sits and twiddles his thumbs or smokes cigarettes he will do so. Here's basically how it works. A "decent" electric vacuum pump is capable of pulling down to about 200 microns. The pump comes equipped with the standard vacuum gauge, which in the U.S. is measuring inches of mercury vacuum. inHG. Not accurate enough to measure microns. It will be bottomed when there's still more vacuum to be had. But a decent micron measuring gauge cost twice as much as the evac pump. A good HVAC guy buys one. Typically refrigeration specs call for evac no higher than 500 microns. Since the evac pump has to work harder and takes longer to draw down those last microns, let's say from 10000 down to 500, but the inHG gauge needle has stopped moving, you let the pump run on for a while. It could take the pump 10 minutes to bottom the inHG gauge, and another half hour to actually reach 500 microns vacuum, which is what indicates an acceptable amount of moisture has been boiled off. Some people - like me - can "guess" by the sound of the pump when it has stopped pulling vacuum. But without an accurate micron gauge, it's really just guessing in the end. I usually end up letting the pump run about 5-10 minutes after both the gauge is bottomed and there's no tonal sound difference from the pump. But without the micron gauge, it's voodoo anyway. I don't sweat it. I've read that pros with micron gauges sometimes have to run the pump for hours to get down to 500 microns. I can buy that. In the past I've repaired my R-12 auto A/C's with no evac, and run them for years after. I started maintaining family cars with R134 some years ago, and wanted to treat them better than I did my old cars. So since one of my kids is a mech and they had an air-operated vacuum pump in his garage, I had him do evacs at work a couple times. That was a hassle for him and me because of timing. So I looked into buying a vacuum pump. First thing I found is air operated vacuum pumps are plain incapable of achieving 500 micron vacuum. Lucky to even reach 2000 microns. And that's with a high capacity air compressor running a looong time. So I bought a mid-level Mastercool electric. About 120 bucks and about 30 for a couple quarts of oil, which is important maintenance on a vacuum pump. Now the other main part is about maintaining vacuum. That doesn't require running the pump, but does require time. I usually let the system set for 2-8 hours with the pump off and isolated when I'm done pulling vacuum and before I charge. Depends on how lucky I feel. That's to see if the system has a leak. Again, that's mostly voodoo without a micron gauge hooked up. The last time I maintained vacuum on the inHG for a couple hours, after replacing the compressor and dryer, Gauge never moved. I still lost R134 from a very small condenser leak, and a year later the car stopped cooling. Supposedly a micron gauge would have picked up that leak because of its sensitivity. But I might be wrong about that, and the condenser wasn't leaking when I tested leakdown. No way for me to prove the timing of events. Anyway, having your own electric evac pump and a gauge set is a good idea for the DIY car or boat guy. Inexpensive enough to pay off the investment. A micron gauge is kinda stretching it, and I don't plan on buying one. I don't mind a little voodoo. Actually it doesn't work that way here. Firstly, one buys the absolutely cheapest vacuum pump that one can find. One has never hear of a "micron gauge" so one uses the standard two gauge set. Time is money and there is another customer waiting so vacuuming (which produces no visible results) is done as quickly as possible - usually until the gauge stabilizes and then load the refrigerant, and then demonstrate the air from the evaporator is cold, shut down and get the money. NEXT! :-) (and damn! it seems to work :-) -- Cheers, Bruce |

Quite a few of your sailing buddies also run their diesel aux at fast idle to charge their batteries. That makes more noise and fumes than a good generator. Granted, a proper, inboard diesel generator is mighty quite. A little splashing is about all one can hear and that's when there is no wind and wave action. The exhaust fumes, however, are the real problem. Why is it that those who run diesel generators always "treat" the entire downwind anchorage to their fumes? Why is it they can't be considerate of the safe breathing of those who are out there because they wish to breathe fresh air. Why can't they anchor DOWNWIND of everybody? Enquiring minds wish to know because the only answer I can ever come up with is it's because they are rude, inconsiderate, self-centered and couldn't care less STAY THE **** HOME Exactly..... What ARE you doing here? -- Cheers, Bruce |

(-: Years ago, in North Thailand, I used to walk past a little welding shop where the guy did most of the work out on the sidewalk. Anyway, one day I came walking by and the guy's got this great big single cylinder diesel engine out on the sidewalk and one of the mounting feet is broken off - big chunk of cast iron with the mounting bolt hole in it. The guy's got it all "vee ed out" and propped up right where it broke off. and he's welding it back on using regular old, 6011, mild steel welding rod. Now, you can ask any welder and he'll tell you that you, "can't weld cast iron with regular steel rods", but this guy is doing it :-) A few days go buy and every day I can see he has welded a little more and finally one day I go by and there is no big engine on the sidewalk. So I ask the guy how it went and he, vary nonchalantly tells me he got it finished and they took it back to the rice mill to install it. I asked him whether he though it would hold and he told me that "none of the other ones I've done have broken". Now just like not vacuuming down an AC for a long time you can't weld cast iron with mild steel rods...... but they do :-) -- Cheers, Bruce |

The ONLY absolute requirement is an anchor light and even a cloudy day will produce more electricity than a good anchor light such as the one I mentioned elsewhere will not deplete the battery bank. Even running lights are optional offshore. In an emergency one can always use a back-up kerosene lamps. -- Sir Gregory |
