Troubleshooting and Repair | Envirotherm Cabinets

Applicable Models:

Problem: Battery Alarm still occurs every 7 days, even after being acknowledged and reset

• Cause: One of the backup battery's voltage may be low.
• Fix:
  1. Replace the battery.
  • Part Number: 70320 - Sealed Lead Acid Battery Backup (12V 9.5A).

Problem: Humidity is not being controlled

• Cause: This could be due to several reasons:
  • The humidity function is not turned on.
  • The float switch is stuck.
  • The solenoid is stuck.
  • Refrigerant gas has been lost.
• Fix:
  1. Ensure the humidity function is turned on by following the instructions in the technical manual.
  2. If the float switch is stuck, replace it (Part Number: 41430 - Stainless Steel Float Switch). This must be done by a qualified technician.
  3. If the solenoid is stuck, replace it (Part Number: 10923 - Water Solenoid). This must be done by a qualified technician.
  4. If refrigerant gas is lost, consult a qualified refrigeration technician.

Problem: The cabinet is not reaching the temperature

• Cause: Inadequate air circulation or interference from adjacent chambers.
• Fix:
  1. Ensure there is enough air circulation around the cabinet by providing adequate spacing.
  2. Check that the outlet of any adjacent cabinet does not face the condenser inlet. If this cannot be resolved, install a deflector.
  3. Check the refrigeration pressure switch has not tripped

Problem: I cannot acknowledge the alarm

• Cause: The chamber may still be in an alarm condition.
• Fix:
  1. Resolve the underlying issue causing the alarm.
  2. Press and hold the alarm acknowledgment button for 10 seconds after the issue is resolved.

Problem: The cabinet is not cooling

• Cause: The pressure switch may have tripped.
• Fix:
  1. Press the red button at the top left of the cabinet to reset.
  2. If the compressor doesn’t start after pressing the button, wait 30 minutes for the system pressure to drop to a safe level (1800 kPa).
  3. Try resetting again.
  • Note: If the pressure switch trips more than twice, contact Thermoline's service team.
