This comprehensive guide will help you troubleshoot and fix your camper fridge when it is not operating properly on gas.
Understanding Your Camper Fridge
To effectively tackle the problem of a camper fridge that won’t work on gas, it’s essential to understand how these appliances function. Most camper fridges are absorption refrigerators, which differ from traditional compressor units.
How Absorption Refrigerators Work
Absorption refrigerators use a combination of gas, heat, and a refrigerant to cool the interior. Here’s a brief overview of the process:
- Heating the Ammonia: The refrigerator uses a burner powered by propane gas to heat ammonia in the system.
- Vaporizing: As the ammonia heats up, it turns into vapor.
- Cooling: The vapor moves through a series of coils and ultimately cools as it condenses back into a liquid state.
- Absorption: The cooling process occurs, absorbing heat from the interior of the fridge and keeping your food chilled.
Understanding these steps helps identify where things might be going wrong if your camper fridge is not working on gas.

What are the common reasons for a camper fridge not working on gas?
One of the most common reasons a camper fridge doesn’t operate on gas is an issue with the gas supply. This can be due to an empty propane tank, a closed valve, or problems in the gas lines such as leaks or blockages. If the propane tank is low or empty, it simply won’t provide the fuel necessary for igniting the burner. Checking the tank and ensuring gas flow is a good starting point for troubleshooting.
Another factor could be a malfunctioning gas regulator or igniter. If the igniter fails to spark, the fridge will not be able to ignite the gas. Additionally, the burner itself might be dirty or clogged with debris, which can prevent proper combustion. Regular maintenance and cleaning can help avoid these issues, but if they occur, it is vital to examine these components closely.
How do I check if the propane tank is empty?
To determine if your propane tank is empty, check the built-in gauge if your tank has one. A gauge displaying red indicates low fuel, while green denotes adequate supply. If there is no gauge, you can perform a simple weight test. Weigh the tank; the weight should match the manufacturer’s details and the weight of the propane remaining, which is typically found on the tank itself. Alternatively, you can pour warm water down the side; the tank will feel cool where the propane resides.
If you suspect the tank is low, try replacing it with a full one for testing purposes. If the fridge begins to operate correctly on gas, then your initial tank was indeed the issue. Always ensure that tank connections are secure and that no gas leaks are present, which can be dangerous. If you continue to have issues even after confirming the propane supply, further investigation into the fridge’s other components is necessary.
What should I do if the igniter is not working?
