Kenmore 795.7555 fridge beeps randomly

[RIPNeilPeart]

Hello
Yesterday, our fridge randomly began to beep now and then, and the display temperatures and Express Freeze light come on and off. We did not have a power outage at any point in the day, and this morning I turned that breaker off for 30 seconds or so.
After turning on the breaker, the beeping occurred 3 times and hasn't happened since. I just opened the left door, and:
1) Both Lock and filter lights blinked
2) Both temeparatures showed 88, and then returned to their low number.

Should i leave the breaker off a longer time?
What may have gone bad?
Thank you

4 digits missing from that model number.

That's the equivalent of a pilot announcing on the radio...

"We're go to..."

And the plane was never seen again.

Yes John, and I love planes. 

The last 4 digits are 2401. Since the opening post, I replaced the main board in the back, and the beeping stopped. 

Last week we returned from a week's vacation, and noticed the return of the flashing temperatures on the front board. The inside temperature felt warm. I reset the breaker, and lowered the temperature to 37 and it cools fine. But it beeps here and there randomly, and the front flashes numbers at times. 

What can I check next?

Start with the basic the outlet proper voltage, polarity and ground.  Next would be the door switches.

Thanks Vance. They definitely beep when they're left open. What else can I test?
