I have that exact model range with the exact problem...and it's also about 1 1/2 - 2 years old. Thanksgiving is only 2 weeks away and I have people expecting a turkey....Please help!

I also have a Kenmore 790.95033503 that is exactly 2 years old and does not heat up. Purchase date 10/31/07 and problem started 10/31/09, ain't that something. From everything that I am reading it is the clock that is malfunctioning, you know from other people having the same problem with Kenmore ovens. The part is running about 100 bucks. I am beyond frustrated that an oven that is 2 years old is already costing money to fix. :mad:

We recently had the same problem with the same model stove.

I noticed the high current yellow wire connection on the relay/clock board was loose. Also the 3 wire clip assembly was barely connecting. Reattaching everything properly didn't help.
I then carefully removed the relay/clock board after taking lots of pictures and marking which wire went where. I gently pried the relay board from the housing and folded it open. It hinged on the ribbon cable. There was a black solder blow out on one of the relay terminals.
There is a lot of room to work on this board. I cleaned the charred area carefully with a soft brass brush and applied solder with the iron set on high. It had the potential to become a cold solder joint again and needed a lot of heat before setting up properly. I also completely embedded some copper wire strands into the melted solder. I believe this helped transfer heat as well as improve conductivity.

(The relay terminal had no contact with the circuit board other than through a cold solder joint. This combined with the current surges from loose wire connections caused the solder to blow out)
My wonderful wife quickly rewarded me with delicious hot biscuits. :)
