My Anet ET5 factory heater cartridge had a little too much amperage flow through it in the past two years. Cheap, thin wires from the manufacturer didn't help!
I went to 3D Printing for help because there's just no support or parts available from Anet, and the tech told me that the CR-10s has the same parts as the Anet ET5!
Creality parts were sturdier and highly available, and I was pleased to discover that they were CHEAP!
2-hours down time... Thanks for the help!
