Propane refrigerators are an excellent choice for off-grid living, cabins, and anyone seeking reliable refrigeration without dependence on electricity, and at Warehouse Appliance, we specialize in helping customers get the most from their propane refrigerators. While these appliances are known for their durability and efficiency, first-time users can often run into a few common questions or troubleshooting issues. The good news is that most problems are simple to fix with basic knowledge and maintenance.
Below, we walk through the most common propane refrigerator concerns and provide practical solutions to help keep your unit running at peak performance:
Understanding Initial Setup and Cooling
One of the most frequent concerns comes from new owners expecting the fridge to cool immediately. Unlike electric refrigerators, propane fridges need 6–8 hours to fully cool down. During this time, avoid opening the doors or loading food, as either action will extend the cooling process significantly.
Another common question involves the light. The light inside propane fridges run on batteries, specifically four “D”-sized batteries. On some models, such as the 11-cubic-foot model, the battery compartment is located on the back and tucked underneath, which can make it a little tricky to find. Once you know where to look, replacing the batteries is straightforward.
Finally, remember to submit your warranty card after purchase to ensure coverage. It is an easy step that provides peace of mind should your refrigerator ever need service.
The Importance of Proper Propane Pressure
For propane refrigerators to function correctly, the gas pressure must be properly set. The standard requirement is 11 inches of water column pressure. If the pressure is too low, your flame will not burn hot enough, and the cooling performance will suffer. You can test this yourself by building a simple manometer, or you can contact your propane company for professional testing. We have also created a helpful guide on how to test propane pressure.
“My Freezer Works, But My Fridge Doesn’t”
This is by far the most common troubleshooting call we receive. Customers notice that their freezer is cold, but their fridge remains too warm. If the freezer is around 30°F, the refrigerator compartment will hover around 50–60°F, which is too warm for safe food storage. For proper operation, the freezer should be 10°F or lower, which in turn brings the fridge down to 40°F or below.
The issue usually comes down to the flame not burning hot enough. To correct this:
- Clean the burner area and flue: A dirty burner produces a weak, yellow flame rather than a crisp blue one. Turn off the propane, remove the cover plate, and use a wire brush and compressed air to clean the area. The flue can also be cleaned with a specialized flue brush.
- Check the flame sound: On high, the flame should be audible from about 10 feet away. If it is too quiet, your propane pressure may be low. Have your propane company test it, or consider replacing the regulator on your propane tank.
- Bypass the thermostat (advanced step): If cleaning and checking the pressure does not resolve the issue, contact us for guidance on bypassing the thermostat.
Frost Build-Up Issues
Frost naturally accumulates on the wire fins in the back of a propane refrigerator compartment. However, if you notice frost building up in other areas, it may indicate a gasket issue. To fix this, use a hairdryer to gently warm the door gasket while pulling it slightly away from the fridge or freezer door while it is warm. Then, close the doors. When the gasket cools, it should reform a proper seal, preventing air from getting inside.
(Note: Be sure to cover any open containers of ice, food, and beverages in a propane refrigerator to avoid excess moisture in the fridge and freezer compartments. Covered ice trays are highly recommended.)
The Flame Will Not Stay Lit
Another common problem with a propane refrigerator occurs when customers report, “I can light the flame, but as soon as I let the gas button go, it goes out.” This is a clear sign of a failed thermocouple. Fortunately, replacing a thermocouple is simple. We carry a universal replacement thermocouple compatible with EZ Freeze, Diamond, Crystal Cold, and Blizzard propane or natural gas refrigerators and freezers.
(Note: It will not work with imported brands such as Unique, Smad, or Smeta.)
