check fuser male /female connector for damage,format hdd,check harness running under fusing unit to lwr rear connector from ih board

fuser was replaced completely, the heater control board. What he decided was the replacement logic board. I wonder whether it was possible to repair plate to be logic board.

I think it is the fuser and I would check the tension screws are all the way down and the shipping screws are removed. Otherwise I would check the thermistors.
