Does anyone know the value of R1 or know where I can obtain a Electrolux PN 3164627 pcb 0046 schematic with parts list? Resistor is complete burnt off CCA.

Did you find out what R1 was? Same thing happened to mine. Let me know if you have a chance.
Thank you, Adam

I think R1 is supposed to be a 221 1% resistor, though it appears the only function is really that of a fuse. It'll take 0.5 A under the fault condition that the L2 relay is not energized when the L1 side of either the broil or bake element is switched on.
It might have been part of a poorly implemented power level control.

I have the same problem. What causes the R1 resistor to fry? What should I be checking before installing a new board? Thanks.

I know this is years later, but for others who have a similar problem, the resistor is red, red, brown, black or 221 ohms.

I decided to replace R1 but oven still does'nt work. My board had a large area around ( what use to be the resistor ) covered with black residue. I'm afraid to spend $225 only to have it burn up again. I'm leaning towards a new oven but if you guys come up with the fix , please post.

I have bought a new board and will install when I can determine why it blew. Here's my blown board....Pic is lighter than the real thing...the black soot part is really black... 65Val attached the following image(s):

I think there is a design flaw/bug, likely in the microcontroller firmware. Occasionally the relays controlling the oven elements are actuated out of sequence and the resistor blows.
After my R1 went up in smoke I replaced it with a jumper as it doesn't have any function in normal operation. We still get occasional failures, now the oven overheats and we need to hit the breaker so not ideal :-/ ... if I get it apart again I'll have to try an externally reset fuse/breaker or PTC.

Thanks for the feed back fellows and I also think this problem is a design flaw. 65val, your board really wet up in smoke. Thought mine was bad till I saw yours. I looked on class action.org and low and behold there is an ongoing investigation for a possible lawsuit against Kenmore and Frigidaire range/ovens sold by sears. Evidently these companies were already aware of the problem but did nothing.( I just wish they would beef up the control board and offer it for a reasonable price.) But, for right now I still have use of the stove top so I'll probably go look at new ovens and report my problem with class action.
