Downdraft blower failure
Blower motor stopped working and the breaker tripped. Horrible smell! from the somewhere in the oven. Looking at the wiring diagram told me that there was a relay board feeding he motor, but I had no idea where it was, which took a little Internet searching to find it. Finally seeing that it was in the rear I was happy to see that there was enough flexible gas line to pull out the stove enough to check the board, which was fried. I replaced the board and then looked for the reason it smoked and found that the blower motor was shorted (and stank horribly).
It was straighforward to replace, but when I put everything back, NOTHING worked at all - no lights on the control panel, nothing. I then checked the voltage across the terminals and saw 240V and was puzzled until saw that there was no 120V to neutral where the plug connected to the back of the stove. The outlet, however, had 120V to neutral. Since it was a molded plug I thought that was not likey to be a cmmon failure, so after killing th breaker I took off the outlet cover that the stove plugged into and found out that the neutral terminal was intermittent.
The neutral contacts were not grabbing the netral terminal on the plug tightly enough and were a little discolored in one spot. All that moving around of the plug while moving the stove probably moved it just enough not to work at all - that thing was a fire hazard that I'm surprised hadn't been the cause of more damage in a house only 12 years old. Rather than try and clean the termnals and trust bending them to be tighter (and worry about metal fatigue) I spent the $10 so that I could sleep better for a tight new 240V 30A outlet.
Everthing works like a charm now.
