Dometic Caravan Fridge Problems

Dometic caravan fridges, commonly found in many RVs and campers, are versatile units that can operate on electricity, battery, or gas. But like all appliances, they can sometimes run into problems. One of the most frequently reported issues is the fridge not working on gas. This article aims to provide insight into potential problems and their solutions.

Common Problems with Dometic Caravan Fridge on Gas:

1. No Spark: The fridge may not produce a spark when trying to light it on gas.
2. Flame Issues: Even if the igniter works, the flame might not stay lit.
3. Inefficient Cooling: Despite seemingly normal operation, the fridge may not cool effectively.

Potential Solutions:

1. Debris/Scale on Ignition Point:
   • Over time, debris or scale can accumulate on the ignition point, especially if the gas mode hasn’t been used frequently.
   • Solution: Access the burner by removing the lower fridge vent and the small metal box surrounding the burner. Clean off the debris/scale. Once cleaned, the spark should be evident.
2. Ignition Battery Issues:
   • Some Dometic fridges have a small battery inside the press button ignition system. If this battery is drained, no spark will be produced.
   • Solution: Replace the battery. Check the user manual for specific instructions.
3. Reliance on Leisure Battery:
   • In some models, the ignition source is from the leisure battery. A partly charged or weak battery can result in a weak spark.
   • Solution: Ensure the leisure battery is fully charged.
4. Air in the Gas Line:
   • If the fridge has not been used on gas for a while, there could be air in the gas line.
   • Solution: Light a gas ring first to draw gas through, which can help expel the air in the pipe. After that, attempt to ignite the fridge.
5. Other Potential Gas Issues:
   • Check if the gas bottle is empty.
   • Ensure the gas supply cut-out device or isolation tap is open.
   • Verify if the burner is misaligned.
   • A defective thermocouple could be the cause.
   • Always ensure the fridge is level.
6. Cooling Efficiency:
   • The cooling process for these fridges can be slow. It might take several hours for the fridge to cool down efficiently.
   • Solution: Regularly check the metal plate in the freezing compartment and the radiator at the back to ensure the fridge is cooling properly.
7. Gas Type Issues:
   • The type of gas used can also impact the performance. It’s been suggested that butane can cause more issues for jets than propane, as it’s considered a “dirtier” gas.
   • Solution: Consider switching from butane to propane.
8. Resetting the Fridge:
   • Some models have a reset function.
   • Solution: If there’s a fault light showing when on gas mode, try pressing the power button until it beeps once and then quickly release. This might reset and rectify the issue.

Conclusion:

While the above solutions can address many common problems, it’s essential to remember that safety comes first. If you’re unsure about any procedure or if the issue persists, consider consulting a professional or certified engineer familiar with Dometic fridges. Proper maintenance and understanding of the appliance can ensure a long and efficient life for your caravan fridge.
