It looks to me like there was a failure in the primary sensor circuit (PSC). The PSC operates automatically whenever the door is opened. The problem occurs when the PSC does operate on a timely basis.
The fix is to operate the PSC on a regular basis. It is commonly activated multiple times during the evening. The PSC needs to open the fridge, remove an adult beverage, and verify that it is cold. In the event the adult beverage is warm, that should trigger an alert on the PSC.
To put this in layman's terms... Drink beer more often, and verify the bottles are cold.
Good luck,
