Heater bed not heating correctly
So odd issue just started happening on my VCore 4 400 hybrid, went to start a new print and the print bed heater got to temp then just started dropping. This caused safety shutdown. Now when heating temp on display goes down?? Any idea what the problem is or how to correct?

Does it heat at all anymore?
Sorry for delay, does not heat up at all. set temp and hold hand on it and get nothing. Then klipper restarts as stated above.
I'd bet it is the thermal fuse built into the bed. Disconnect it and check continuity
I’m assuming that’s in the bundle taped underneath? So cut open that tape to access.
If no continuity, then yeah that's how you'd get to it
I don't know about the later models but on mine you can pull it out although it does not come out easily.
Ok so what’s a good vendor to get a new fuse to US? Also if someone were to accidentally cut through the thermistor wire attempting to free said fuse I’m assuming they could solder it back and shrink wrap it and it would be ok?
as long as you can solder that size wire well, that should be fine
You can buy them on Amazon or AlliExpress. I would crimp the wire rather than solder since it is exposed to high temperature.
