You go to the inlaws to be their handyman? You must really like those folks...In-laws water heater is blowing fuses in redundant fuse box. Like everyday. Box gets hot and is sketch. I replaced the heating elements, no fix. Unit is less than a year old. Tonight I am going to trash the fuse box and install a receptacle/plug and see if the issue is the fuse box. They're gonna burn this house down pretty soon it seems..
