There is one thing i left out. In the refrigerator service business
there is a old rule that says if there is a dought as to what the
problem was with the defrost system. As a rule you change the defrost
timer and move on.

That's not the rule for me. It's a pretty simple diagnosis. Heater, limit
switch, timer.
Even the newer adaptive defrost models with electronic controls are easy to
figure out.

I would not like changing a timer only to get called back.

this is TRurtle.

first These words was not written when they had electrinic controls,
but on standard block timers.

Second You don't need to spend about 6 to 8 hours at the refrigerator
customers house and change him about $500.00 on a $500.00 refrigerator
to hunt down a defrost problem. You ohn out to see the defront
terminator it ok, then you ohm out the defrost element is ok, and then
see if the defrost timer is running. Now Ed , you do all the test you
can do on this refrigerator and still find nothing wrong . Now What do
you do ?

Thirdly the words that i stated was the old time refrigerator service
people [ not me ] who have workied on these refrigerator all thier
lives and have this as a rule of their business. I was told this by all
the refrigerator service people eversince i was a kid [ 40 something
years ] when you can't find a problem with the defrost system -- change
the defrost timer. Also sears tells their tech this same words when
they can't find anything wrong with the defrost system -- change the
defrost timer.

Fourth No disrespect at all but these words have been carried down the
through the years and is still used in the refrigerator business today.
Now what i think here. On the old stuff i would say yes , but on the
new stuff NO, Sorry if my opinion differes from your !
