Frequently Asked Questions
Q: How to improve the cooling performance of my motorhome fridge?
While you are enjoying your holiday, keeping your food and beverages safe and chilled is a must. Here is some advice on how to optimise the cooling performance of your motorhome refrigerator
Q: Can I buy shelf clips or bins for my refrigerator?
Yes. Original Thetford spare parts are available through your dealer or Thetford Service Centre.
Q: Which thermostat setting is the coldest?
We advise to set the refrigerator on cooling level 3, with an ambient temperature between 15°C and 25°C. A higher temperature needs a higher cooling level, a lower temperature a lower level.
Q: Where can I find what kind of model my refrigerator is?
In the refrigerator. Behind the vegetable drawer or on the side wall there is a data plate with all the model information.
Q: My refrigerator smells, how can I clean it?
It is important to clean the refrigerator regularly for optimal performance. First remove the shelves, door bins, slide-out box and the drawer. Then clean those parts and the inside of the refrigerator with a soft cloth and a mild household cleaner. Also use a wet, soft cloth for the outside of the refrigerator.
Q: How can I defrost my refrigerator?
First remove all food, wrap it tightly in a newspaper and put it in a cold place or in an insulated bag. Then remove the drawer and leave the doors open. Put some dry towels in the refrigerator to catch the remaining water. When the refrigerator is defrosted, thoroughly dry the inside.
Q: Is it okay to defrost my refrigerator/freezer using a hair dryer, heat gun or boiling water?
No, the sudden change in temperature will cause the inner surface of the refrigerator/freezer to distort. This will not be covered under warranty.
Q: How can I prepare the refrigerator before my journey?
You can do this after a minimum of 8 hours cooling, the food can be placed in the refrigerator. Do not completely cover the cooling fins with food, to preserve an optimal performance of the refrigerator. Make sure air can still circulate around the fins.
Q: Can I replace my refrigerator?
Yes, in most instances you can replace your motorhome fridge. Locate your current model and find a suitable replacement with our fridge replacement chart . For further information on replacing your refrigerator, please contact your dealer or Thetford Service Centre.
Q: Why doesn’t my refrigerator always work when I use solar panels?
The 12 Volt supply could be too high due to the usage of solar panels. Your refrigerator has a built-in safety measurement for this, we advise you to check this with your dealer or Thetford Service Centre. Please check the warning code and contact you dealer or Thetford Service Centre.
Q: Which is the best fridge for situations where I require a high performing fridge on only 12V?
In this case, a 12V refrigerator is the best solution.
Q: Which fridge is best suited for off grid conditions?
An absorption fridge is the best solution, because it runs on gas, 230V and 12V.
Q: Why isn’t my refrigerator cooling?
Please check if you switched on the refrigerator according to the instructions. Check if the vehicle stands level or if there is an available energy source to start the refrigerator with. If none of this is the case, please contact your dealer or Thetford Service Centre.
Q: Why isn’t the door closing properly?
It may be that the door of your refrigerator needs to be adjusted. Contact your dealer or Thetford Service Centre to check this.
