Bud,
You're barking in the wrong dog park. You want guys that do this work
for a living to peer through their screen and tell you whats wrong
with what they cant see. Then you want us to shit all over the tech
that came out because YOU think he diagnosed it wrong.
How much time, money and comfort have you lost now due to being such a
tightass? You would have been ahead in the long run if you would have
just gone ahead and had the repair done..............THEN, if the tech
put the board on and it didnt work, it would have been HIS problem.
NOT yours.
Take you lumps skin flint.
Keep tossing parts at it or call someone that knows how to do it
right.
OH yeah, dont forget to replace your thermostat. Its almost always the
thermostat.
