Kenmore Elite gas dryer, fried controller board

Model Number: 110.73932101

Brand: Sears Kenmore

Age: More than 10 years

My dryer won't stay on when I press the START button. I opened the front console and started looking around, and I saw that the controller board had a few failed components on it (See picture). Seems like a simple fix, replace the controller board... only it looks like the board is now $175, which does not make me too happy. Well, I'm good at soldering, so why not try repairing the board? (I know the failure of these components may have damaged other parts of the board and it's lifetime might be up, BUT I wanna try replacing the components before I shell out $175 for a new board... or a new dryer, given that a new board is about 1/3 the cost of a new dryer.) I may have used the even heat option once, and most of the time we use the dryer in low heat or just air fluff.

I mostly have component questions.

From what I read in this thread, the root cause may be underpowered diodes, so I'll probably upgrade those.

For the burned traces, I was just going to use a length of wire to replace the trace. (with sufficient gauge wire, probably 16 gauge)

The capacitors are rated at 220uF and 330uF, both 63v. Would there be any benefit or downside if I went to 100v or 160v caps?

The resistor looks to be brown white blue gold, so 19M Ohms, 5% tolerance... I think. The "gold" band doesn't look metallic at all. Every other option doesn't make much sense aside from possibly Yellow Blue Silver Brown (.46ohm, 1% tolerance). And of course, every picture of this board I can find is a completely different revision so the resistors are different. The problems I can see with this is that 19Mohms is rather high, and .46ohm is pretty low. Some people on another forum suggested that it could be a 47 something (x10 ohm or x100K). Any clue what the value could be, or better yet, is?


Is there any downside from choosing a .5w resistor to replace this (I think) .25w resistor? (And did I read the color code correctly (19Mohm)?)

Any other components that I should replace?

Board is 3976633 rev.d, and I've replaced the motor relay a few years ago.

Those are all good questions, but as appliance techs. we just replace the board, not components on the board.

Hopefully another tech. or member thats replaced components on the board can assist you.

If no one replies, I did find a new board for currently $129 here:
