| Symptom | Likely Cause | Quick Fix | |---------|--------------|-----------| | | Loose mains plug or tripped breaker | Verify plug is seated, check circuit breaker, reset the internal fuse (accessible behind the rear panel). | | Temperature never reaches set point | Heater fault or sensor drift | Run a Self‑Test (Menu → System → Diagnostics). If the heater element shows “FAIL”, contact service. Re‑calibrate temperature sensor. | | Door interlock constantly engaged | Door sensor misalignment | Close the door firmly, ensure the latch aligns with the sensor pin. Clean any dust from the sensor area. | | Excessive humidity reading | Desiccant exhausted or N₂ leak | Replace desiccant cartridge; verify N₂ connections are tight and leak‑free. | | Unexpected power spikes | Over‑loaded external power strip | Connect the unit directly to a dedicated outlet rated for ≥ 15 A. | | Data logging stops mid‑run | SD card full or corrupted | Replace the SD card (minimum 8 GB, FAT32) and re‑format via Menu → System → Storage . | | Hazard | Mitigation | |--------|------------| | |
