Heater Failure - Resin Temperature Control System Not Functioning
Quick Answer
Error code 150 on your Formlabs Professional Resin 3D Printers means: Heater Failure - Resin Temperature Control System Not Functioning. This is usually fixable — see the step-by-step guide below.
Likely Causes
  1. Heater element in the printer base has failed
  2. Temperature sensor for the resin heating system is disconnected
  3. Heater controller circuit on the mainboard has a component failure
  4. Thermal fuse has blown due to a previous overheating event
How to Fix It
1
Check the current temperature reading on the touchscreen; if it reads 0C or an unchanging value, the sensor may be at fault
2
Run the heater diagnostic from Settings > Diagnostics > Temperature Test
3
Monitor the temperature over several minutes to see if it is rising at all or remaining flat
4
Contact Formlabs support with the diagnostic report, as heater replacement requires professional service
5
As a temporary workaround, ensure the ambient temperature is at least 18-25C to allow printing without the heater (print quality may be affected)
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
