Affected Models
Applies to all models
CR-10 SECR-10 Smart ProEnder-3 S1 ProEnder-3 V3Ender-3 V3 SEEnder-5 S1K1K1 Max
Likely Causes
  1. Heater cartridge has failed or has an open circuit
  2. Loose connection at the mainboard heater terminal
  3. Incorrect voltage heater cartridge installed (12V in a 24V system or vice versa)
  4. MOSFET on the mainboard controlling the heater has failed
How to Fix It
1
Use a multimeter to measure the heater cartridge resistance (should be ~14 ohms for 24V/40W)
2
Check the screw terminals on the mainboard for the heater output and tighten if loose
3
Verify the heater cartridge voltage matches the printer PSU voltage (24V for most Creality models)
4
Monitor the temperature graph in the host software to see if temperature rises at all or stays flat
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
