Dometic RUA/RUC user modes and temperature behavior
Use this when a Dometic RUA or RUC owner is choosing Eco, Performance, Turbo, Quiet, or defrost-related modes and wants to understand expected cooling behavior.
Use this atlas to identify likely meaning and prepare for service. Shut off power, LP gas, fuel, or water when a listed appliance condition involves flame, gas smell, exhaust, generator shutdown, high temperature, moving jacks/slides, refrigerant, 120 VAC, control boards, repeated ignition failure, or a persistent lockout. Call the appliance maker, RV dealer, or a qualified RV technician for repair.
Owner-safe checklist
- Use only normal front-panel user-mode selection.
- Record selected mode, temperature setting, ambient heat, and whether cooling changed after the mode selection.
- Call Dometic or qualified service if a mode change causes repeated faults or the refrigerator will not cool.
