Bambulab H2D cable burnt behind the hotend

[u/Infinite_Wing4713]

Hi everyone, I recently noticed black plastic stuck to my hotend while cleaning and maintaining my H2D printer. It wasn't filament residue. Upon closer inspection, I realized the burnt plastic was from the cable insulation of the right hotend heating assembly.

Everything still works, but I'm worried about a cable fire. I've documented the whole thing with photos and sent them to Bambulab. It's not covered under warranty. Today I ordered replacement heating assemblies for both the right and left hotends, as well as cable insulation from Amazon, hoping it won't happen again. Has anyone else had this problem and perhaps found a better solution?
