I have received the replacement relay and capacitor today.


Installed them (it was a 2 minute job).


Plugged in the fridge.


The compressor happily started working normally, mildly vibrating and
indicating in all respects that it is running fine.


Happy after 2 minutes, I turned off the fridge, and reinstalled the
rear insulated covering panel and ground.


Plugged in again and I HEARD THE SAME OLD DREADED BUZZING SOUND. Now,
the compressor motor would not start again! It busses fomr several
seconds and the relay clicks and turns it off.


I am completely puzzled as to why exactly it turned on once, but would
not turn on again.


Any idea?


Take the cover back off and see if anything changes? Mebbe fridge got
shoved into the wall, and the cover got bent, and is making something
not work?


I'm no fridge expert, but when something stops working when you put the
lid on, that tells me the lid is somehow binding something up or
shorting something out.

"when something stops working when you put the lid on, that tells

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 8€³ drives as shown he

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.


Many of these kinds of things end up being cracked connector solder or
chips that fail when heated. BTDT
