Why Is My Caravan Fridge Not Working on Gas?

You arrive on site, switch your caravan fridge over to gas mode, and… nothing. No cooling, no reassuring flame sound — just warm milk and growing frustration. If your caravan fridge is not working on gas, don’t panic. This is a common issue for touring caravan owners and in many cases, it’s something simple that can be diagnosed and resolved quickly.

In this guide, we’ll explain the most common reasons your caravan fridge won’t run on gas and what you can do about it.


1. There’s No Gas Supply Reaching the Fridge

The most obvious and most common cause is that gas simply isn’t reaching the appliance.

Check that:

  • Your gas bottle isn’t empty
  • The bottle valve is fully open
  • The regulator is securely connected
  • Any isolation valves inside the caravan are switched on

Sometimes after changing a bottle, air can become trapped in the gas line. This can prevent the fridge from lighting. Try lighting your hob first to purge air from the system, then retry the fridge.


2. The Gas Burner or Jet Is Blocked

Caravan fridges running on gas rely on a small burner and jet to create a steady flame. Over time, dust, rust flakes, debris or even insects can block the burner.

If the burner is partially blocked, the fridge may attempt to ignite but fail. You might hear clicking without ignition. In this case, the burner assembly may need cleaning, a job best carried out during a professional caravan service to ensure it’s done safely and correctly.


3. The Ignition System Isn’t Working

Most modern caravans use automatic ignition systems. If the ignition electrode is faulty, misaligned or dirty, the gas won’t light.

Signs of ignition problems include:

  • No clicking sound when switched to gas
  • Clicking continues but no flame appears
  • The fridge cuts out shortly after attempting to ignite

Electrical faults or low 12V supply can also prevent ignition, so check your leisure battery is sufficiently charged.


4. The Caravan Isn’t Level

It might surprise you, but caravan fridges (particularly absorption fridges) must be level to work efficiently on gas.

If your caravan is parked on a slope, the cooling system can’t circulate properly, which may prevent it from cooling — or even lighting — correctly. Using a levelling system ensures your fridge operates safely and efficiently every time you pitch.

5. The Flue Is Blocked or Restricted

The fridge flue allows exhaust gases to escape safely. If it becomes blocked by dirt, soot or insect nests, the fridge may shut down as a safety precaution.

Regular servicing includes checking and cleaning the flue to ensure safe gas operation. Never attempt to dismantle gas components yourself unless qualified.


6. The Thermocouple Has Failed

The thermocouple is a safety device that detects whether a flame is present. If it doesn’t sense heat, it shuts off the gas supply automatically.

If your fridge lights but won’t stay lit, a faulty thermocouple could be the cause. This requires professional inspection and replacement.


When to Seek Professional Help

If basic checks don’t resolve the issue, it’s best to book your caravan in for inspection. Gas appliances should always be serviced by trained technicians for safety and compliance.
