Possible Causes

High ambient humidity, door gasket leak, failed heated door frame (if equipped), poor door insulation

How to Fix / Troubleshooting

Safety: No major electrical hazard, but unplug before working on door components.

Steps:

  • Check environment: High humidity can cause temporary condensation. Use a dehumidifier in the room if possible.
  • Inspect gasket: Ensure the door gasket seals tightly all around. Replace if damaged.
  • Heated frame (if present): Some Dometic models have a heated door frame to reduce condensation. Check wiring to the frame heater and test for continuity. Replace the door frame heater if open.
  • Usage: Avoid leaving the door open for extended periods, which increases moisture inside.
