The 2020 manual references a Power Ventilator for the refrigerator. When I searched the part number - 690394 - HighSkyRVParts.com returned an "Airstream OEM" part, which appears to be a standard 12V
"computer" style fan. It comes with a sensor.
I'm not sure where it's installed on the 2020 30' Classic, but the parts website says it will run when the refrigerator is on and the temperature is hot. Duh.
Maybe the sensor is bad? Again, I'm not sure where it's located, but I'd guess at either the top of the refrigerator compartment (under the roof vent), or just at the bottom of the coil. If the latter, then it might be visible from the outside refrigerator access panel.
