RV House Refrigerator Storage: Should You Leave the Door Open?

Quick Take

For your new house refrigerator during RV storage, you should absolutely leave the doors cracked open just like you did with your old RV fridge. House refrigerators can be prone to mold and mildew issues during storage because they have better seals that can trap humid air inside. The key difference is that house fridges will be completely powered off during storage (unlike some RV fridges that could run on propane), making proper ventilation even more critical to prevent moisture buildup and unpleasant odors.

Common Causes

Moisture trapped in house refrigerators during storage creates the perfect environment for mold, mildew, and bacteria growth. Unlike the old-style RV absorption refrigerators, house fridges have much tighter door seals designed for energy efficiency, which means any residual moisture or food particles get sealed in completely. This creates a humid, stagnant environment that promotes microbial growth.

House refrigerators also have more plastic components, drip trays, and complex drainage systems that can harbor moisture. The evaporator coils and interior surfaces can accumulate condensation over time, especially in climates with temperature fluctuations. Additionally, house fridges often have ice makers and water dispensers with residual water that can become breeding grounds for bacteria if not properly drained and dried.

The rubber door gaskets on house refrigerators are particularly susceptible to mold growth because they create such an effective seal. When combined with any food residue or spills that weren't completely cleaned before storage, you're setting up perfect conditions for problems that can be expensive to remediate and may leave permanent odors.

Preparation

Before storing your RV with the house refrigerator, start with a thorough deep cleaning using a mixture of warm water and baking soda (2 tablespoons per quart). Remove all food items, including those forgotten items in door compartments and crisper drawers. Pay special attention to cleaning the drip tray, which is often overlooked but can be a major source of odors.

If your house fridge has an ice maker, run the cleaning cycle according to the manufacturer's instructions and ensure all water lines are completely drained. Remove any water filter cartridges and store them separately in a sealed bag to prevent them from drying out completely. Clean the water dispenser area thoroughly and run clean water through the system until it runs clear.

Wipe down all interior surfaces with a dry cloth after cleaning, and check that the drainage hole at the back of the refrigerator compartment is clear. Remove all removable shelves, drawers, and door bins to clean separately and allow better air circulation. Place an open box of baking soda or activated charcoal in both the refrigerator and freezer compartments to absorb any remaining odors and moisture.

Check your RV's electrical system to ensure the refrigerator will be completely disconnected from power during storage. Some RVers make the mistake of leaving house fridges plugged in during storage, which can lead to compressor issues if the RV isn't level or if power fluctuates.

Repair Steps

To properly prepare your house refrigerator for storage, first ensure it's completely defrosted if it has a freezer compartment. Allow at least 24 hours for complete defrosting and use towels to absorb melting ice. Once defrosted, remove all water from ice maker lines following the manufacturer's specific drainage procedure (as solenoid valves may need proper closing), then disconnect power.

Prop both the refrigerator and freezer doors open using wooden blocks, foam wedges, or specialized RV fridge door props available at camping stores for about $10-15. The opening should be approximately 1-2 inches - enough for air circulation but not so wide that dust and insects can easily enter. Some RV owners use bungee cords to secure doors in the slightly open position. Important: Secure doors properly before transport to prevent them from swinging open and causing damage while moving the RV.

Install moisture absorbers designed for RV use, such as DampRid or Dri-Z-Air containers, placing one in the refrigerator compartment and one in the freezer. These typically cost $3-5 each and need replacement every 2-3 months during extended storage. Position them where they won't fall over when the RV moves or settles.

Create a storage checklist and tape it inside the RV near the refrigerator to remind yourself of the preparation steps for your next storage period. Include items like "doors propped open," "moisture absorbers placed," "ice maker drained," and "power disconnected." This prevents forgotten steps that could lead to expensive cleaning or repairs later.

When to Get Help

Contact a professional RV service technician if you discover mold or mildew growth that covers more than a few square inches, as this may require specialized cleaning agents and potentially replacement of door gaskets or internal components. Professional mold remediation typically costs $200-500 but is worth it to prevent health issues and preserve your investment.

Seek professional help if your house refrigerator has persistent odors that don't respond to normal cleaning and airing out, as this may indicate contamination in the drainage system or behind panels that require disassembly. Similarly, if you notice any refrigerant leaks (oily spots around coils), this requires immediate professional attention as DIY refrigerant work violates EPA regulations and requires certified technicians.

Get professional assistance if your house fridge won't restart properly after storage, especially if it makes unusual noises, doesn't cool evenly, or the compressor seems to struggle. Extended storage can sometimes cause compressor oil to settle incorrectly, and forcing a problematic unit to run can cause expensive damage. A service call typically costs $150-200 but can save you from a $800-1200 refrigerator replacement.
