Before you begin: Use your RV and component manuals for model-specific procedures. Stop and use a qualified professional for electrical, propane, structural, or other work beyond your training.
Know what type you have
Absorption and compressor refrigerators work differently. The manual identifies power sources, ventilation requirements, leveling limits, and expected cooling behavior. Do not apply a household refrigerator rule to an RV absorption unit without checking the model.
Write down the make and model, then locate exterior vents, fuses, and controls that the owner is allowed to inspect.
Test before loading food
Start the refrigerator early enough to verify it reaches a safe food-storage temperature. Use an independent thermometer and check both compartments. Warm food, blocked air circulation, or frequent door opening can slow cooling.
If it will not cool, confirm power source, settings, and external conditions before assuming a failed cooling unit.
Keep vents and seals clear
Inspect accessible exterior vents for leaves, nests, or debris without disturbing gas or electrical components. Clean the door gasket and check that the door closes evenly. Interior fans or added parts should be used only if compatible with the model.
Never block designed ventilation openings to keep pests out. Use approved screens or a technician-approved repair.
Clean and store it dry
Remove food, wash removable shelves and interior surfaces with an approved mild cleaner, and let them dry. Follow the manufacturer’s storage-door position so moisture does not become trapped inside.
During winterization, check whether the fridge has an ice maker or water dispenser that also needs draining.
Stop for gas or cooling-system faults
Soot, propane odor, ammonia smell, yellow residue, overheating, or repeated fault codes require immediate attention and qualified service. Do not modify a sealed cooling unit or bypass safety controls.
Manufacturer manuals & further reading
Use these official resources to find details for your equipment. Match the brand, model, and revision; another RV’s procedure may not apply to yours.
