Thetford Fridges Problems

Thetford fridges are popular choices for caravans and mobile homes. However, like all appliances, they can occasionally run into issues. If you own a Thetford fridge and are facing problems with its cooling mechanism, especially when hooked up to mains electricity, this article might be of help.

1. Problem: Fridge not cooling on mains hook up but works on gas.

Possible Solutions:

• Ensure the fridge has been given ample time to cool, as it can take longer than expected. A handy tip is to place a teaspoon of water in the ice box; it should freeze within an hour or so.
• Check the control panel and make sure it’s set to the correct power supply. Modern fridges often have settings like ‘A’ for Automatic.
• Inspect the power source. 3-way fridges should take their 12V cooling power directly from the vehicle alternator, ensuring cooling only when the engine is running.
• Examine the fridge’s cartridge heaters. Each power source (12v and 240v) has a cartridge heater element, which can fail over time but is replaceable.
• Check for tripped MCB’s which control the fridge. Also, verify if a socket hasn’t been inadvertently switched off.
• If you’re comfortable with electrical work, conduct checks with meters and take resistance readings.

2. Problem: Heat emanating from the back of the fridge.

Possible Solutions:

• This can sometimes indicate an issue with the cooling unit or other internal components. It’s best to consult professionals in this case.

3. Problem: Red and flashing green lights on the control panel, indicating potential issues with voltage.

Possible Solutions:

• The recommended range for Thetford fridges is 195v-259v. A plugin meter can be used to ensure your power supply is within this range.
• If the fridge indicates low voltage despite a satisfactory power supply, it’s possible that other electrical devices in the vicinity are drawing too much power.

4. Problem: Cooling unit blockage.

Possible Solutions:

• A blocked cooling unit can prevent efficient cooling. Sometimes, this necessitates the replacement of the fridge.
• Interestingly, some users pointed out that gas can sometimes offer more power than electric heaters, potentially allowing the fridge to work even with a compromised system.
• Turning the fridge upside down overnight can occasionally resolve issues like airlocks.

5. Problem: Fridge works on gas but not on electricity or battery.

Possible Solutions:

• This might be related to the cooling system or power sources. Consulting with experts or technicians is advised.

General Tips:

• For a quick check, you can tell if the heating side of the fridge is functional by placing your hand on the top of the external fridge vent. After a short while, you should feel heat.
• If the fridge is still under warranty or you’ve recently purchased it, contact the dealer or manufacturer for potential refunds or repairs.
• When faced with significant issues, always consider consulting professionals or taking the appliance to a workshop.

Conclusion:

While Thetford fridges are robust and efficient, like all appliances, they can sometimes face operational issues. It’s essential to diagnose the problem accurately and take the necessary steps to rectify it. Whether you’re handling minor issues on your own or seeking professional help, staying informed can ensure your appliance has a long and productive life.
