Anyone with the 12V DC Norcold refrigerator every had issues with the E3 error message? We bought a 2021 Heartland Trail Runner and the fridge is giving the E3 message and beeping intermittently 4 to 5 times in a 24 hour period. It’s staying cold like it should but supposedly it’s a low voltage or high voltage issue. I seen an article somewhere talking about that there’s been issues in the past where they used a to small of a gauge wire. Just curious if anyone else has experience this issue.
