Find an RV Refrigerator by Opening Size & Power Type

Choosing a replacement RV refrigerator starts with the opening in your cabinetry, not the capacity printed on the old door. Use this measurement and power-type guide alongside our existing Dometic and Norcold refrigerator size charts to narrow down suitable models.

Quick checklist: Measure the opening in three directions, note your power supply, and check door-swing clearance. Then use the existing manufacturer size charts and installation documents before ordering.

Step 1: Measure your refrigerator space

1. Height: measure the clear cabinet opening, top to bottom.
2. Width: measure between the narrowest fixed sides of the opening.
3. Depth: measure available space while allowing for the manufacturer's required ventilation, cords and connections.
4. Access: verify that the appliance can pass through the RV entry door and interior passageways.
5. Door clearance: allow space for hinges, drawer or door swing, and surrounding trim.

Keep separate records of the cabinet opening and the actual exterior appliance dimensions. Manufacturer installation cutout and ventilation specifications control whether a unit can be installed safely.

Step 2: Choose the power system

12V DC compressor refrigerators

Suitable only when the RV's DC electrical system, charging capacity, wiring and ventilation meet the refrigerator's installation requirements. Check expected electrical consumption if you camp without shore power.

Absorption and other propane/electric refrigerators

Check the exact available fuel and electrical supplies, clearances, cooling-unit ventilation and compatible installation instructions. A 12V compressor replacement is not automatically a drop-in fit for an older absorption model.

Used refrigerators

Compare each individual listing's dimensions, condition, installation details and shipping eligibility. Used inventory varies by unit.

Step 3: Use the existing dimensional references

• Dometic and Norcold refrigerator size chart
• Dometic-to-Norcold refrigerator cross-reference
• Shop repair parts by existing refrigerator model number

Step 4: Compare installation features

• Door hinge position and door-opening clearance
• Cabinet mounting, trim and access panels
• Existing venting and manufacturer-required airflow
• Power type, voltage, wiring and battery capability
• Propane connections where applicable
• Interior capacity, freezer configuration and shelf arrangement

Fitment reminder: A refrigerator may fit the opening physically but still be unsuitable for the existing power, venting or installation arrangement. Verify the specific manufacturer's installation manual before ordering.
