Digital control

I have a drop in jenn-air. it has a digital clock, time etc., all in one.

PROBLEM

the digital clock stops displaying however when I open the oven door the digital clock is shown. After 5 minutes the display turns off?

This has never happen before. Do I take the front off a look for a lose wire? The push button to the oven door operates OK?

The model number you posted does not come up. Verify and repost it please.
