Dometic CFX5 Smartphone Connected App Prep

Use this official Dometic source when the smartphone is connected to the CFX5 but the app is not working before contacting support.

Owner-safe checklist

Record the CFX5 model, phone operating system, app version, connection state, cooler display state, and any alert or warning shown.
Save screenshots of the connected-but-not-working app state, photos of the cooler label and display, and the official Dometic support title you matched.
Do not repair internal cooler electronics yourself; shut the cooler down if it overheats, smells unusual, or keeps showing alerts, then use Dometic support or qualified RV service.
