No need to trash pick / dumpster dive. People know I can fix almost
anything, so I get phone calls, E-mails and deliveries of used items.
To give you an idea of how creative I am at saving money, I am making
some tongue & groove boards from scrap pallets to use as sub flooring.
Politicians should only get paid if the budget is balanced, and there is
enough left over to pay them.

A man after my own heart. I became interested in homebrewing, and am about
ready to kick it off.
I DO need a dedicated refrigerator, though.
I managed to get six Cornelius kegs with connectors and a regulator for
$100. I may get God knows what more, as I am swapping with a guy who wants
my 1200 gal. water tank, and he works for Coke/Dr. Pepper and I am pretty
sure he is getting this stuff for free. I am negotiating getting all the
"stuff" from a home brewer who was SWMBO'd, except for a $12 wort cooler,
which I can build cheaply, and all for $125.
Weather here is hot, and SWMBO will surely complain of the odor of the
flatulent fermentation process, so I guess I'll have to retire to the
containers and make a dedicated beer brewing area, complete with hot water,
triple tank NSF sink, dedicated refrigerators, and welded racking systems to
make things easier.

With the state of the economy today, "working fridges", particularly the
top/bottom varieties can be had for a song, and sometimes for just picking
When I was about 18 (1966), I found an old refrigerator in a motel they were
tearing down. It had the freezer part on top, but only one door. Wish I
knew the brand name, but for the time, was top of the line. Probably go for
a grand on ebay today.
I brought it home, covered it in zebra terrycloth, and put it out by the
pool for a beer and soft drink fridge. It was running when I sold the
house, and had probably been running at least twenty years prior.
They don't make stuff like they used to.
Heart surgery pending?
Read up and prepare.

Your motor has lack of lubrication and is seizing up. Since it's in a
sealed can you can't fix it. Putting lubrication in the coolant could
help but you can't do that either without unsoldering connections and
capturing the coolant and could cost more to fix than to throw out and
buy a new one.
I look outside this morning and everything was in 3D!
I understand the implication of what you are saying, which is that it
is an expensive fix.
But just for my education, what exactly is wrong so that there is lack

A chip of grunge in one of the oiler holes on one of the crank bearings

older units, too, but less often because everything was over-built back
It's not a stretch for a guy with your skills to change the compressor --
say, with one from a 20-year-old fridge. You'd need the tools to
evacuate the system. You'd need to install access valves. You'd need to
either find a "friendly" with some R-22, or replace the charge with
But generally, a fridge isn't worth the work, when you can get another
one for under $100.
I've yet to see an old refrigeration unit that used R22 since R12 was
the first of its type. I use something called R416a in place of R12
and it's more efficient, takes less refrigerant to do the same job
and it runs a lower head pressure which makes it good for old systems
because it puts less of a load on them. Oh yea, it's a drop in, no oil
They're pretty scarce. He might be better with an F-ing professional,
We had a "refrigeration professional" out to the factory a three months
ago to replace an A/C compressor under warrantee.
Long story short... I had to do (actually completely UN-do, clean the
work, and RE-do) the brazing for him. He couldn't lick all the leaks.
To his defense, it was a BAD position in which to work, he was a short
little sucker, the unit was tall, and it was a tiny, tight workspace
inside the coil of that unit. But damn... I'm just a pyrotechnics guy,
and _I_ was able to Sil-Flo that thing down tight in one try.
So much for "refrigeration professionals".
Yeah... I know there are some. I learned to braze from one. But this
guy's was the sort of skills I see all the time over in alt.hvac. And
they SCREAM about how they're the only ones competent to work on systems.
Hell... half of them can't figure out which way is "up" for liquid feed
with R410a. (or why),(and it's printed on the bottle)
yep. I have repaired a number of them with the same symptom, but the
symptom can be caused by more than one problem.
As someone else said, a _thoroughly_ frozen-up evaporator can cause the
symptom, because the liquid refrigerant won't boil out of the coil fast
enough to reduce the head pressure before the next cycle is requested.
A lot of compressors now come with PTC thermistors in place of the
potential relays they used to employ to switch the start cap out of
circuit. They tend to fail rather easily in a high-humidity environment.
Although they're not terribly expensive, I replace all of them with
potential relays; sometimes scavanged from other similar-sized
compressors, sometimes new.
Then, of course, it's possible the new start cap is failing.
The compressor could be on the way out. If the bearings are getting
sticky or tight, the compressor will be harder to start than it should
be. This eventually manifests itself as a "locked rotor", and nothing
you can do (effectively) will fix that, except replacing the compressor.
Foreign material in the closed system can cause it, too. You didn't say
anything about ever opening it, but flakes of insulation from the
compressor windings and corrosion flaking off the inside of improperly
cleaned or improperly brazed lines can all do it. These, too, are
generally fatal problems, and cannot be fixed merely by replacing the
compressor and re-charging.

I always add a little Supco88 to a system when replacing a compressor in

refrigerator for home use doesn't need as much as a commercial unit but
it only needs a little to help it. A small dryer with an access valve is
not a bad idea either when a refrigerator compressor is replaced and the
odd fridge that has a starting problem can benefit from an all in one
hard start relay and capacitor package. I know a lot of guys who do a
great job on HVAC equipment who have trouble working on itty bitty
refrigeration units. I prefer the big stuff myself like 60 to 4k tons,
it's easier to work on. 8-)

I usually only see those for AC units where a burnout is often much
more spectacular. I haven't paid attention to the small bullet dryer
specs to look for acid neutralizing media content. Acid Away is a
liquid that mixes with the refrigeration oil. I use the liquid in
addition to the Sporlan HH series dryers on an AC burnout. If the
AC evaporator and line set is badly contaminated, I use a cleaner
blown through it with nitrogen too. In my opinion, the Acid Away
protects the compressor much better than a dryer alone because it
stays in the oil in every part of the system like the windings of
the compressor motor that are vulnerable to being damaged by acid.
There are those critters out there who will just throw a system in

That could be true. I once made a homemade control for a welding
machine. It was MIG, stick and plasma capable and welded pretty good
(though it was not as convenient to use as an industrial welder like
Anyway, when I calculated the amount of little parts, doodads, and my
time at a VERY conservative rate, the time investment in the welder
control was so enormous that at something like $20 per hour, I could
have used this time to buy the nicest brand new Miller welder out
But the difference between making that weld control, versus fixing the
fridge, is that when I was asking about various specifics, I got
educational, useful answers, instead of screaming and howling like I
get from some (but not all) losers that seem to hail from alt.hvac. I,
obviously, always welcome any useful ideas that would come from
constructively minded HVACers.
