Heated bed MOSFET; what parts to replace?

Hello,

Found the culprit in the intermittent power to the heated bed. It was the heated bed MOSFET connector, but I am unsure if I have to replace just the removable part or the part attached to the board. I am pretty much an electronics novice and have learned everything I know about our 3D printing machines through lots of trail and error. I've attached a picture of the clearly melted component and I'm wondering if I just need to replace the part that comes off the board or the part that's attached as well. Hope that's an easy question!!

Cheers,
James

Usually the heat damages/oxidizes the connector surface so if you do not replace both, then in a short time it will fail again.

Thank you for that information. Now I guess I need to learn how to solder.... :/
