Dometic RUA/RUC defrosting and ice buildup
Use this when a Dometic RUA or RUC refrigerator has frost or ice buildup and the owner needs the Dometic defrost boundary.
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
- Turn the refrigerator off with normal controls and remove food before defrosting.
- Leave the doors open and wipe compartments dry after the ice melts.
- Do not use mechanical tools, heat guns, or sharp objects to remove ice or loosen stuck items.
- Call authorized service if heavy frost returns quickly or cooling remains poor after defrosting.
