It's like this:
GE replaced control and added TCO
GE replaced TCO
TCO just blew again
I wouldn't even think of harassing the GE guy here, I get that he's just doing his job. But I want to see exactly what is being replaced this time around.
If I can't run any cycle other than "normal" without blowing it again, I'd say that's definitely a pattern and something the "fix" isn't taking care of. Are thermal cutouts flukey things that tend to go on their own?
