I'm no fridge expert, but when something stops working when you put the

In a much earlier life, I used to install and repair Radio Shack
TRS-80 workstations. My company also used the Storage Expansion Unit
which could house up to three additional 8âł drives as shown here:
http://www.trs-80.com/wordpress/trs-80-computer-line/model-ii/
These expansion bays were notorious for not working once you put the
cover back on. You'd repair the unit or add a drive, test all three
drives with the cover off and then install the cover and the 84,000
screws that kept it on. Invariably, one of the drives (it would be
random as to which one) would no longer be accessible.
You had to loosen screws, tweak the cover, slap the box, whatever, to
get it working.
With hundreds of these workstations installed in everything from
offices to chemical processing areas, you can be sure that we did a
lot of bench work trying to determine what the problem was in an
effort to make our on-site work easier. We never figured it out and
were thrilled when they started replacing them with the original IBM
PC.

They cut one corner too many by tin plating the edge connectors, then
plugging them into connectors with gold plated contacts. At one time
there was a special connector sold that you soldered to the tin plate,
and had gold plated contacts to mate with the ribbon cables.

re: "At one time there was a special connector sold that you soldered

Trust me, I know all about the many corners they cut! ;-)
However, how would this particular connector issue be impacted by the
installation of the case? The case had no connectors, it was just a
metal shell.
P.S. Before installing the TRS-80's, we opened up every keyboard and
ran a wire from the circuit board ground to the plastic case. Before
we did that, weird things would happen when the user touched the
keyboard.
The worst was seeing the disk drive light turn on and knowing that the
program and/or data disk was now corrupt. The least was hearing the
daisy wheel printer print out a single character.
We had some users that were so paranoid about their data that they
wired a grounding bracelet to the sprinkler system and would hook
themselves up before they touched the system.

The problem hasn't gone away.
We've been farkin' with a CD duplicator for a month. It would randomly fail
to eject a CD. Replacement of the CD drive with a new one didn't help. We
finally got it to work flawlessly but when we tightened the screws holding
the drive in place, back to the same symptom.
Turns out, tightening the screws distorted the drive (made of old beer-can
metal).
Loosening the screws somewhat returned the duplicator to perfect
functioning.
Many times we just left half the screws out altogether!On 9/3/2010 12:46 PM, DerbyDad03 wrote:

However, how would this particular connector issue be impacted by the

metal shell.
Just a guess but tightening the crews could distort the case enough to
put stress on the drives, altering their alignment thus they (especially
with the old stepper-motor drives) no longer have proper track
alignment. Â Solution would be to leave the drive mounting screws on one
side a little loose so they support the drive but don't put any load on
it--a little Loctite would keep them from working loose in service.

hell, my fridge has done that for years... (Really, it has).
The reason is 'high head pressure' and you have to let it sit for as
much as 20 to 30 minutes (typically, but can be longer) between startup
cycles.
Shouldn't take 20 minutes for the head pressure to bleed off enough for a
restart. Unless of course there is a partial restriction in the high
side. If the system has moisture in the freon the end of the cap tube can
ice up causing a restriction. Or some contaminates could plug the cap
tube partially. Normally the head pressure should reduce sufficiently to
allow a proper working compressor to restart in 5 minutes or less.
