Clock,timer.& oven don't work. No electric on top panel All burners are fine

Hello, welcome to FixYa.

It sounds like the hi-limit safety thermostat may be tripped, the scenario you described is exactly how this would manifest
"clock,timer.& oven don't work. No electric on top panel All burners are fine"
...that is the component that typically trips/activates during a self clean on many ranges. You shouldn't need to open the front control panel, but access is through the back. (this can also occur during power surges)

You'll need to slide the range/oven outfrom the cabinet. If you slide the unit away from the wall and unplug it you can check the hi-limit.
It will either be a non-reset type hi-limit or push to reset. If non-reset it needs to be replaced, if push to reset type, simply pushing in the red button will get you back up and cooking in no time.

**Unplug the range from the wall first of course...safety first**

Once you remove the panel you will need to look for a switch/thermostat which looks like either of these...
NON-RESET


PUSH TO RESET


The replacement if necessary are available at "searspartsdirect.com" or "repairclinic.com" to name a couple.

Let me know how you make out. Good luck. I'll watch for your reply and if you need anything further I'll be glad to help in any manner I can.

Does the high limit solution applies to gas and electric
