Caravan Fridge Not Working on Gas: Common Causes and Prevention
For many caravan and motorhome owners, a fridge that doesn’t work on gas is a common and frustrating issue. Interestingly, the root cause for most of these problems isn’t wear and tear—it’s lack of use. In fact, in 85% of the leisure vehicles I service, the gas function on the fridge fails simply because it hasn’t been used regularly.
Here’s what you need to know to keep your fridge running smoothly on gas and avoid unnecessary repair costs.
Why Caravan Fridges Stop Working on Gas
- Lack of Use Causes Solenoid Sticking
The solenoid valve, responsible for regulating gas flow to the burner, can stick if it’s not used regularly. Without regular operation, the valve may seize, preventing the fridge from functioning on gas. - Other Common Issues
While solenoid problems are the most frequent cause, other issues include:- Thermocouple failure: This safety device stops gas flow if the flame goes out. A faulty thermocouple can prevent the fridge from igniting.
- Burner blockages: Dust, debris, or spider webs can clog the burner, stopping the flame from igniting.
- PCB faults: The fridge’s printed circuit board (PCB) controls its functions. If it fails, the gas system may stop working.
Prevention: Use the Gas Mode Regularly
One of the simplest ways to keep your fridge working on gas is to use it regularly. Here’s how:
- Start Your Fridge on Gas While Setting Up
When you arrive at your campsite, fire up your fridge on gas. This gets the fridge cold faster than using an electric hook-up (EHU). Once it’s cold, you can switch to EHU. - Minimize Gas Usage Concerns
Don’t worry about gas consumption—it’s minimal. A short run on gas won’t significantly affect your gas supply but will go a long way in preventing the solenoid from sticking. - Incorporate Gas Testing into Regular Maintenance
If you’re already performing maintenance, make sure the fridge is tested on gas during your routine checks or annual service. This ensures all components, including the solenoid and thermocouple, are in working order.
Why Regular Testing is Essential
During a service, both the fridge and the water heater must be tested on gas as part of the carbon monoxide (CO) safety test. If you’ve never run your fridge on gas, this could reveal issues you didn’t know existed, and repairs can be costly.
By regularly using your fridge on gas, you not only maintain its function but also ensure it operates safely during inspections.
Troubleshooting Gas Fridge Problems
If your fridge isn’t working on gas, here are some steps to identify the issue:
- Check Fridge Vents
- Enusre the winter vent covers have been removed to ventilate the exhaust.
- Check for Ignition
- Listen for the click of the igniter and watch for a flame in the burner area.
- If there’s no flame, it could be a thermocouple, solenoid, or burner issue.
- Inspect the Burner
- Remove debris or blockages that may prevent ignition.
- Test the Thermocouple
- A thermocouple that’s not heating properly won’t send the signal to keep the gas flowing.
- Examine the Solenoid
- If the solenoid is sticking, you’ll need to clean or replace it.
- Check the PCB
- A damaged PCB will require replacement by a professional.
Avoiding Costly Repairs
Many of these problems can be avoided by simply using the gas mode occasionally. Yes, encouraging regular gas use might cut into the income of service engineers, but as a responsible owner, you’ll save money and avoid unnecessary hassle.
Final Thoughts
Caravan fridges are reliable appliances, but like any system, they need regular use to function properly. By firing up your fridge on gas regularly, you’ll not only keep it running efficiently but also prevent common problems like solenoid sticking.
Spending a few minutes running your fridge on gas is a small effort that can save you hundreds of pounds in repair costs. Plus, it ensures your fridge is ready for use no matter where your adventures take you.
Stay proactive, and enjoy your caravan trips with a fridge that works on both gas and electric modes!
Why does my fridge work on electric but not on gas?
This is often due to lack of regular use of the gas mode. The solenoid valve may have stuck, the burner could be blocked, or the thermocouple might have failed. Regularly using the gas mode helps prevent these issues.
How much gas does a caravan fridge use?
The gas consumption of a caravan fridge is minimal, especially when only used to get the fridge cold or for short periods. It’s a cost-effective way to keep the system functional without significantly depleting your gas supply.
My fridge won’t ignite on gas. What should I check first?
Ensure your gas supply is turned on and connected properly.
Check for debris or blockages in the burner area.
Inspect the thermocouple and solenoid for signs of damage or wear.
Make sure the igniter is clicking and producing a spark.
Can I clean the burner myself?
Yes, you can clean the burner by gently removing any debris or spider webs using a soft brush or compressed air. However, if you’re unsure or uncomfortable, consult a professional.
