Electromechanical relay failure on Power Board
My 82 year-old mom’s left front burner failed some months ago. Last night she did something with the controls and noticed that the burner came on! Then it went off. She fiddled with the controls again. At some point, white smoke was pouring out; enough so that she was quite alarmed. She called me as she tripped the circuit breaker. I opener her up (the range, not my mom) and took a look-see. I am calling it a blown relay requiring a power board replacement.
Check out my photos and please tell me if I am on the right track, and if I've overlooked anything.
Main question: What causes an electromechanical relay failure on a power board such as the one found on this range?
Using it. Nothing you did or didn't do could prevent this from happening.
Is Power Board replacement the correct first remedy?
(please follow link above and see shot of whole back of range)
Need I have any concern over...
1) Stain on "box"?
2) Discoloration around, and rising up from ... whatever the round thing is?
3a) Marks rising from fan motor assembly?
3b) Material dripping down from fan motor assy? (see close-up shot)
What should I ask (or do) that I have failed to ask about (or do)?
Replace the board?
Thanks in advance,
