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!
