Brand: Whirlpool
Model Number: SF385PEEN0
Main Symptom: Bottom igniter no power
What happens & when: Broiler top igniter has power but bottom igniter does not. Top igniter went out years ago but never used broiler so didn’t care. Recently, bottom igniter went out so I went ahead and ordered both cuz they were pretty cheap. Both worked for about 10 minutes or so then they didn’t. It’s an old stove so I was gonna say eff it since I had a pretty big toaster oven. Now I at least want to give it one last try b4 completely scrapping. All 4 burners work fine. The control board looks pretty good except for around the Zener diode (D13) looks a bit toasty. Also the LED display/module has a cm black spot in upper left face. I’m wondering if I just need to replace the D13 diode. I have a cheapy little AstronAI 4000 Auto Sensing multimeter. With the board out (no power), I tested for resistance at D13 and the other 4 diodes next to it for the hell of it. With the board mounted, D13 shows 25.xx volts. I didn’t put the faceplate back on to activate the “Bake” button which I assume will show the parameter of a normal Zener diode reading (.05 - .07 volts), no? Given what I’ve explained so far, should I take the diode reading after pressing ‘Bake’ or does it matter? TIA
Error Code (if any): None
Parts or tests already tried: New igniters (multiple)

I believe that that brown area is just from age and the heat generated by the diode. I think the bigger problem is that when you put the new ignitors on that old board the power draw fried something, especially since it affects both bake and broil. A new board ( Whirlpool WP6610059 Range Microcomputer | Genuine OEM Part ) is not available anymore. but you may be able to find one on a 3rd party site. As far as repairing it yourself, if you have the know how and the tools it may be a cost effective solution
Thanks for the quick reply Jeffery. I haven’t tackled a single appliance that I haven’t fixed myself. If it may not be the diode, any idea what it might be? We’re in an area that has all underground utilities that are decades old. There was bad neutral a few years back between the transformer and my meter that dropped my voltage to 92. I’m sure that was responsible for subsequent premature failing of a few of my devices over the following year. I’m not sure it effed with the stove but who knows.
Possibly the relays, beyond that it’s all guesswork.
Do you know how many relays and their location? I looked for an old manual on .pdf a while back but I couldn’t find one.

Thanks, I just found this one also.
Thanks that had a lot more useful information. I saved it
Here’s the url I linked to, they may have more if u need:
No problem. I’m a bit leery on a bunch of the “free manual” sites. Ironically, this site mimicked the sketchy sites with all the giant “download” pop-ups so I don’t know if I just got lucky.
