Something doesn't work so you take it apart and troubleshoot all the
components. You can't find anything wrong so you put it back together
and...IT WORKS PERFECT! It has happened to me for forever but what's going
on? My latest is the icemaker in the kitchen refrigerator. I spent hours
and hours finding documents and troubleshooting. No, it wasn't frozen-up,
(the most common fault it seems) the motor worked, the thermostat checked
out, the heater passed muster. The water valve is OK and all cleaned out.
(I've replaced plenty of those in different units over the years). Of
course, I find nothing else that could cause it to crap out so put it all
back together and...it works just fine. Go figure. I've had hundreds if
not thousands of this kind of thing, I'll bet everybody else does too!


It's quite likely an electrical problem with a connector. The metal in
the connectors slowly oxidizes and eventually fails to conduct like it
should. I learned long ago that step #1 was to unplug and replug all
electrical connectors. The root cause of intermittent problems is usually
the connectors.


That's why I used to use a Q-tip and GC 'Tunerlube' to coat
contacts. It kept oxygn and other gasses away from the contact surface.
