The remainder of the model number is 2602 (790.78852602) which is supposedly just the color code for subject model. The control board is likely to cost approximately $170.00. Is there some troubleshooting that one can perform to reset/repair the control board before replacing it?
Unfortunately, Kenmore doesn't supply online tech. sheets for me to link you too, You will likely have a tech. sheet in the console you can diagnose it with.
But I'm interested in know what happens after you press bake? Does it let you put the temperature in that you want to bake at? If it lets you, then you press start nothing happens? If you look in your oven do you see the oven igniter glow bar putting out an orange glow in the bottom of your oven?
If you have a voltmeter you can test the voltage from the bake output terminals on the control board, it should read 120 volts.
When BAKE is pressed on the touch panel, one is able to enter the desired temperature, but the igniter does not glow. No oven.
If PRE is pressed (instead of BAKE), and then the desired temperature entered, the broiler igniter glows (and the top broken bar on the display illuminates). After a while, the broiler igniter will turn off and the display will show that the oven is operating (solid bottom bar on display illuminates; top bar extinguishes). The display will continue to display PRE. After several more minutes (while the display continues to show PRE), the oven igniter glows, and the oven finally engages. The display continues to show PRE until the preset temperature is attained at which time the oven beeps and the desired temperature is displayed.
I guess I could live with this, but it's not the way things should work.
