Hi Brent-Sandy,
Welcome to the Heartland Owners Forum.
I'm assuming you bought the Residential Refrigerator Option and the inverter you're referring to is the one the factory installed to power the frig only.
The frig maker changed the compressor a few months ago and the newer one draws more power at startup of the compressor, causing the inverter to shut down intermittently. Heartland has modified programming of the inverter to handle the new power demand. While they fixed units in production, a few that were in transit (or in transit lots waiting to be shipped) haven't had the fix applied.
Call Heartland Customer Service at 877-262-8032 / 574-262-8030. Have your VIN # ready. They should be able to tell you how to proceed on getting it fixed.
Btw, we have an owner-written Residential Refrigerator User Guide that has a bunch of information not found in the manufacturer's manual. You might want to download a copy.
Here's a link.
