Hoping to get some help- so glad to find this place. I have a Kenmore electric double wall oven, model 790.49533312- I think it might be about 8 years old.

Unfortunately, the top oven will heat up to temp,
but won’t stay warm. When I select ‘bake’ it gets up to temp, and then immediately allows the temperature to start falling. This happens much slower when the fan runs during Convection bake/roast, but the temp still drops. Broil seems to work OK, bottom oven seems to work.

I’ve had Sears out multiple times, and frankly the local service ain’t great! They suggested I replace the relay board, so I ordered a brand new replacement relay board. After Sears skipped a scheduled appointment and then wanted to charge me to reschedule, I decided to do the relay replacement myself. Relay board went in fine, surprisingly easy job! I am not particularly handy, but I’m pretty much resolved not to call them again.

This afternoon, I set the oven to bake at 350. Using a leave-in digital thermometer, the temperature hit 365, then fell down to 190 over the next hour. The display LCD reads 350 the whole time, doesn’t fall with the actual temp. Using convection bake, it fell from 350 to 290 in about 20 minutes.

Any ideas what to do next? Is this a computer control board issue, or maybe something wrong with the bake element itself? Any suggestions would be tremendously appreciated. I’d be happy to try anything. I’m not used to using my multimeter or fixing things but I’d love to knock this job out.

thanks!

Hi,

Physically check the upper oven hidden bake element for any breaks in it and broken wire terminals on it. Make sure you turn the breaker off to your Oven first!

Here's the upper oven hidden bake element for your model:
318601604 Element


Also look at what this guy found happened to his hidden bake element: FIXED: Kenmore Elite 790.47893604 (Electrolux) - Bake Element Terminals.

His Kenmore 790 model uses that exact same hidden bake element yours does.

Here's another thread that uses your exact same Bake Element:
He explains how to access it.

Thanks so much. I was sorta hoping the issue would be something up top with the electronics- just so I wouldn’t have to pull the whole oven down and out of the wall! It’s pretty heavy!:giggle: That said, it’s going to be good to get this off my plate and working right! Thanks for the references here!
