Have A Freezer That Seems To Open The Door By Itself For No Reason, I Replaced The Electronic Control Assembly Back In April Of 2015,
All Seemed To Be Good Until About Two Weeks Ago And Then I Would Find The Door Open And The High Temp Alarm On. Don’t Understand What The Problem Is, Any Help Greatly Appreciated,

Check to make sure that the unit is level front to back or leaning slightly to the back.
Check the door hinge cams, (item 22A in section 03 and item 26 in section 05).
The door rides up and down on these and when shut they are on the down slope of the cam, holding the door closed.
