Kenmore Dual Elite Oven not heating
Kenmore 790-75503207 oven not heating up. Element resistance is ~18 ohms. Temperature indication appears correct. Side oven works, broiler works. Can hear relays picking up for short while then dropping out, but appears to only be K2 picking up and not K1 when looking at voltage on E7 & E6. Is there something else that it could be other than the control board (318010102) ? Is there a circuit diagram available for 318010102 ?

The oven not heating can be concerning. I found some information for you that I am hoping will help you with the oven. I am adding the link below to help you with your question while you wait for your expert response. It may take 24-48 hours. I do hope that this will help you with the oven.

There is not an internal circuit diagram available for the specific control board component (part 318010102). I posted the wiring schematic for the range in the image below. That range uses a DLB (Double Line Break) relay in that L2 leg of power as shown in that image. I traced the circuits for the bake element on that wiring schematic. If the element is getting the L1 leg of voltage but not the L2 leg, then that DLB relay could be causing your problem. You could also have a wiring failure or a bad electronic oven control board (part 318010102). This information should help you test those components to determine the cause of your failure. Note: Use extreme caution when checking live voltage. Wear electrical safety gloves and safety goggles. Unplug the range after live testing is completed. The range should be unplugged when internal components are accessed or exposed . If you need more help, reply with additional details.

Thanks for the info but the oven is already fixed. I traced the fault to the BA relay on the control board. I removed the BA & BR relays and installed the healthy BR relay in place of the failed BA relay, now the oven works fine and broiler is awaiting a new relay. I will buy a new relay for $3 and install in BR instead of paying $250 for a new control board when only a $3 relay failed. From reading this forum along with several others, this appears to be a common problem with this control board and BA relay after about 4 or 5 years. I will buy a few extra so when it happens again, I'll be ready. The Omron G8P-UA-006203 relay is a proprietary build, but per other forums is identical to a standard Omron relay with a 15V coil, G8P-1A4P DC15. Hope this helps some other readers who have the same failure.

I too am experiencing this SAME problem with my Kenmore 790-75503207. DON - thank you for posting your fix. I'm going to give it a try, just need a little guidance. any chance you can post a little more detail how to fix? I'm talented in many area's, so fixing this shouldn't be too much trouble, I'm just not sure where to start... take the current control board off/out of the Stove? then..... Thank you, Jason
