What to do if my Dometic RML8 does not cool in 12V operation?
- KKatherine BrownSep 9, 2025
If your Dometic Refrigerator isn't cooling when running on 12V, start by checking the on-board fuse and replace it if necessary. Make sure the on-board battery isn't discharged; check it and charge it if needed. Ensure the engine is running. If these steps don't fix the issue, please inform Dometic Customer Service, as the heating element might be defective.
