How to Fix / Troubleshooting

Safety: Unplug the freezer before accessing switches or control electronics.

Steps:

  • 1. Test door switch: Verify that the interior light responds correctly to door opening/closing. If not, test and replace the door switch as needed.
  • 2. Check alarm buzzer: If the alarm never sounds, the buzzer on the control board may be defective. Inspect for physical damage.
  • 3. Wiring inspection: Trace the door switch wiring to the control module and check for continuity and secure connections.
  • 4. Replace control module: If the switch and wiring are good but E19 persists, the alarm circuit on the main control module may be faulty and require replacement.
