2006 Frigidaire Smoke Show!

[thatwasherguy]

Hi everyone! Hope you’re all well. Today, the 2006 Frigidaire range had its first major breakdown in a long time. We were trying to bake some chicken when the Electronic control started beeping. Initially, I thought that it was the timer going off, until I noticed that it was beeping in a more rapid rhythm than it does for the timer. When I looked at the display, F10 was flashing. I had just enough time to process this when smoke began pouring from the bottom of the control panel! Needless to say, I ran to the garage and turned off the breaker to it. Once it cooled down, I pulled it out and took the back cover off, and was greeted by this:

Here’s a better view of the carnage.

One of the resistors (R-41) decided that it was time for it to fly, and cooked several other things when it got hot. Needless to say, that board is toast (literally!).

It’s back, just in time for the holidays!

I wasn’t about to let an old friend die that easily, so I got online and found out that my local appliance parts store had a board in stock, so I picked it up, and installed it. I just got through baking a pizza, and everything is working as it should. This new board definitely has some different qualities than the old one. The relays are from a different manufacturer, so they sound different when they actuate. The LED’s are also brighter, and the beeper horn has a slightly different pitch to it. Has anyone else noticed differences like these when replacing a control board?

Thanks,

Looks like yet another case of "too much of vulnerable electronics" compromising an appliance.
The original problem might have been poor soldering of parts, substandard parts, who knows?
It's the way things are made today......

Parts suppliers come and go, different relays 19+ years later isn't surprising to me.
Seems the original was fairly reliable. Why someone would blame that on the way things are made "today" is rather absurd.
Hope you get another 19+ years. I'm sure the board was far less than a new range.

How much was the replacement board?

Wonder how far the shorting / burning would have gone if you did not cut the power supply? I can't see a Fuse anywhere on the pictures of the board that should burn out before it got to the point it did in your pictures. Did I miss seeing a fuse? Glad it was a quick fix for you! Looks like a nice stove.

Question:
Where is the oven heat exhaust vent located?, if it has one.
My Tappan gas range's vent port is at the bottom center of the control panel.

The reason I am asking is because electronics cannot withstand or last if exposed to severe heat, particularly capacitors and semiconductors.

Well this board did last for almost 20 years. Seems it's designed just fine.

I think age and power surges and spikes also play a part in the longevity of boards and power supplies.
