been out to this just after christmas and put new door lock on, and connection was fine, went out last week and replaced interlock because getting error codes again and terminal was still ok but lock was noticeably warm to the touch. replaced it anyway in case it was a dud, but then out again this week and terminals cable is melted and got signs of burning around the [1] & [2] tags. theres no visible seal damage, and 3rd lock ive just put on now gets red hot amost immediately. its a 4tag instant one, and im assuming its just drawing too much current, as never come across them get this hot before.
PCB looks perfect, no error codes other than door sensed not shut
anyone have any ideas why its happening? im not leaving a 3rd interlock on since the original was replaced in case it catches fire
