How to Convert an RV to Use a Propane Refrigerator?

April 5, 2026

Quick Answer

To convert an RV to use a propane refrigerator, install a propane tank, connect it to the refrigerator, and ensure proper ventilation to prevent carbon monoxide buildup. This typically involves replacing the existing electric refrigerator or modifying the RV's electrical system.

Preparing the RV for a Propane Refrigerator

To begin the conversion process, determine the RV’s power requirements and ensure the propane tank can meet them. A typical RV propane tank holds 20-40 pounds of propane, which is sufficient for a refrigerator. Consider a 20-pound propane tank for a small RV and a 30-40 pound tank for a larger one. Connect the propane tank to the refrigerator’s propane valve, ensuring a secure and leak-free connection.

Installing the Propane Refrigerator

Propane refrigerators are available in various sizes and types, including absorption and compressor-style models. Measure the RV’s available space to determine the correct refrigerator size. When installing the refrigerator, ensure proper ventilation to prevent carbon monoxide buildup. This involves installing a carbon monoxide detector and ensuring adequate airflow in the RV. Connect the refrigerator’s propane line to the propane tank and turn on the propane supply.

Electrical Modifications and Safety Considerations

Electrical modifications may be necessary to accommodate the propane refrigerator. Consult the RV’s electrical system and determine if modifications are required to prevent electrical overload. Install a separate circuit for the refrigerator or upgrade the existing circuit breaker. Additionally, consider installing a propane detector and a CO2 monitor to ensure the RV’s safety.
