If your caravan fridge cools perfectly on 240V but refuses to run on gas, you’re not alone — this is one of the most common caravan fridge complaints, especially after storage or long periods without gas use.
The good news: in most cases, the fridge itself isn’t faulty. Gas operation relies on a few specific components that are far more sensitive to dirt, airflow, and ignition issues than electric mode.
This guide walks you through why gas mode fails, how to diagnose the issue step by step, and when it’s time to call a professional.
What You’ll Learn
- Why caravan fridges can work on 240V but not gas
- The most common gas-only failure points
- Simple checks you can safely do yourself
- Signs of ignition vs gas supply problems
- When not to DIY
This guide is suitable for all caravan owners, including beginners.
How Caravan Fridges Work on Gas vs 240V
On 240V, the fridge uses an electric heating element.
On gas, it relies on:
- Gas supply
- Burner jet
- Ignition system
- Flame detection
- Proper ventilation
That extra complexity means gas mode is more prone to issues.
Step-by-Step: Why Your Caravan Fridge Won’t Run on Gas
1. Confirm the Gas Supply Is On
Start with the basics.
Check:
- Gas bottle valve is open
- Correct bottle selected (if dual bottles)
- Changeover regulator hasn’t tripped
- Other gas appliances work (stove, hot water)
If nothing else runs on gas, the issue isn’t the fridge.
2. Check the Fridge Control Panel
Modern fridges may:
- Require manual gas selection
- Show fault lights or error codes
- Need a reset after storage
Turn the fridge fully off, wait a few minutes, then restart in gas mode only.
3. Inspect the Burner and Jet Area
This is the most common failure point.
Common issues:
- Dust and dirt buildup
- Spider webs in the burner tube
- Blocked jet orifice
These prevent proper flame ignition even with gas present.
4. Check Ignition and Flame Detection
If you hear clicking but no ignition:
- Igniter may be dirty or misaligned
- Burner may not be lighting
If it lights briefly then shuts off:
- Flame sensor may not be detecting heat
These are gas-only components and don’t affect 240V operation.
5. Inspect Fridge Vents and Airflow
Gas operation produces heat that must escape.
Blocked vents can cause:
- Overheating
- Flame shutdown
- Safety cut-outs activating
Always check both upper and lower fridge vents.
6. Consider Storage-Related Issues
After long storage:
- Gas lines may contain air
- Burners may be dusty
- Regulators can stick
Running another gas appliance for a few minutes can help purge air from the system.
Common Causes When Fridge Works on 240V but Not Gas
| Symptom | Likely Cause |
| No ignition at all | Gas supply or igniter fault |
| Clicking but no flame | Dirty burner or blocked jet |
| Flame lights then stops | Flame sensor issue |
| Works briefly then shuts down | Ventilation or overheating |
| No response in gas mode | Control board or selector issue |
What Not to Do
- Don’t dismantle gas valves
- Don’t use compressed air on jets
- Don’t bypass safety systems
- Don’t assume fridge is “dead”
- Don’t ignore gas smells
Gas systems must always be treated with caution.
When to Call a Professional
Book a licensed technician if:
- You smell gas
- Burner won’t light after cleaning
- Ignition components need adjustment
- Control board faults are suspected
- Fridge shuts down repeatedly
Gas fridge repairs often require certification.
Key Takeaways
- 240V working means the cooling unit is fine
- Gas mode relies on extra components
- Dirty burners are the most common issue
- Ventilation affects gas operation heavily
- Many fixes are simple — some are not DIY
