Norcold fridge e3 code

[raptor727]

So I just recently purchased a 2022 Jayco Jay flight 264bh with solar charging. Upon purchase I was informed the Norcold fridge was replaced so it's not even 6 months old at this point.

It started this code about a month ago randomly but would keep cool and was not very often maybe once a weekend trip fast forward for now its every hour or so and won't stay cold. So I removed the fridge and checked voltage while plugged into shore power it was 13.5V when started the fridge continually dropped voltage over the course of 2 hours down to 11.9V so I'm thinking I have a voltage supply issue.

So I suppose my question is should I start at the power inverter or is that voltage normal? It never seemed to stop decreasing and this was all done on a bright sunny day so I think it was all from the solar panel and the battery. Any and all advice is appreciated

Just noticed I didn't post the code its E3 for voltage supply issue from what I've read so far

It's good to hear that you found the problem! I'm not sure why none of us responded, as several of us have an electrical background. On behalf of all of us, I do apologize for the failure to offer help!
