Years ago, GE started providing circuit board
with some refrigerators. And they had a lot of
bad ones. Some just had a burnt or cold solder
joint. I've given a couple to a computer repair
man I know, who has reworked the solder joints
for me. And a couple came back to life.
Does anyone out there know of a board repair
service, or do we just pitch em out and sell
the customer new ones?
I've done board soldering when I was a teen.
The one I took out today looks realy cold.
Plan is to get to a friend of mine who's a
computer repair guy.
Board retails for $175. I hate to just pitch

Understood. I have thru-hole and SMT equipment so can
tackle most "problems" that I am faced with. But, it's
usually not practical if you are a business placing real
values on your labor costs, etc. Esp if you have to provide
a warranty: how do you know that something else in the
device won't toast your repairs, leaving you to "pay
for" them *twice*?
I'll "re-cap" a motherboard that is known to be a likely
candidate for that *before* the caps start to fail (once
they do, there are no guarantees that the components on the
board haven't already been exposed to stressful voltages
from the increased ripple on those supplies). Likewise,
most power supplies, TV's, etc.
Aside from "favors", it also lets me keep current with
manufacturing trends and failure modes -- learn from
OTHER PEOPLE'S mistakes!
(I also learn which vendors to avoid! :> )
the range timers/clocks. They'd send a rebuilt one
and the customer would send in the core. It was like
starters and alternators from the local parts store.
No idea if some one like that is online or Ebay
for circuit boards.

I normally do pinball machine circuit board repairs on machines that are 20
to 35 years old. Also, I have repaired circuit boards in other equipment i
n the past such as these:
Manitowac commercial ice machine (in a theater). It had a bad soldered-in r
elay on the circuit board. Replaced it with a relay socket and plug-in rela
y. Machine repaired and operated correctly.
Hamilton Beach commercial drink mixer. It had a bad speed control pot. Manu
facturer wanted $50 plus shipping for it. They also said it would be a week
before they shipped it out. So I went to Radio Shack and bought an almost
exact replacement for $3 and installed it. Machine is still working today o
n that pot.
Modern residential refrigerator (brand name escapes me). Had several blown
electrolytic capacitors on the control board. Replacing them brought this r
efrigerator back to life.
Hot tub (brand name also escapes me. Had 4 blown electrolytic capacitors on
control board. Replacing them also brought this machine back to life.
It's worth it to at least give it a try repairing those boards yourself. Ho
pefully you have a decent capacitor ESR meter to find bad electrolytic capa
citors. Mine paid for itself the first week.

You can usually recognize bad caps from their brand names, bulging/broken

with high temperatures and high ripple currents that lead to internal
Caps are cheap (more or less). I've seen folks selectively replace only
the "defective" caps on a board. Where's the logic in that? Do you think
the others are less likely to fail or will somehow be more convenient to
replace at a later date?
