How to Fix It
1
Measure heater cartridge resistance with a multimeter (should be approximately 14 ohms for 24V/40W)
2
Check the heater terminal connections on the mainboard and tighten if loose
3
Monitor the temperature display to determine if it rises at all or stays at ambient
4
If resistance is correct but still no heating, the mainboard MOSFET may need replacement
