Jeff,

I'm not sure I follow the sequence of events. The service guy comes out,
tests, diagnoses the problem (bad element and bad board), replaces the
broiler element as authorized, and leaves because you won't authorize the
board replacement. Is that right? Why did you authorize the broiler element?
After the tests and diagnosis what did he say to you? Just a bad element?
Bad element and a bad board? Does the oven element work?
Like you, I'm surprised the breaker did not trip. PC boards can fail
without "burn marks". I'm troubled by the absence of error codes. Why does
the tech want to replace the board? How does he know that the new element
isn't at fault or a wire?
