Hotend Thermistor E3D
The hotend thermistor is subject to constant X-axis translation and high-frequency vibrations. Over time, the internal copper strands undergo fatigue failure near the heater block or at the cable loom transition point, causing an intermittent open circuit that the EinsyRAMBo board interprets as a critical temperature drop.

Heatbed Thermistor NTC 100k
The heatbed thermistor cable is subjected to constant Y-axis movement. While the bend radius is generally larger than the hotend's, the wire can still fail due to strain at the solder joint or the point where the cable bundle is secured to the heatbed frame.

Einsy RAMBo Mainboard
In rare cases, the analog-to-digital converter (ADC) or the pull-up resistors on the mainboard's thermistor input circuit can fail or develop cold solder joints, resulting in incorrect voltage interpretation even if the sensor itself is functional.
