1.The fridge must be as level as possible. Older fridges are more susceptible to level fluctuations, check your fridge floor rather than the caravan floor if you have doubts. Level your caravan at the wheels using levellers or wooden blocks, never level using your corner steadies.
2.Most people run their fridges on 230v electric, however, if the site or you have power failure then losing your food can be a problem. Throughout the year, use your fridge on Gas periodically. This will not only keep the burners and ignition working but also give you peace of mind that the fridge will work The handbook will instruct you how to work the fridge on gas.
3. If your fridge is fitted on the door/awning side then overheating can be an issue. Your fridge will work to an ambient temperature of 25 degrees C above this then the fridge begins to struggle to hold temperature. On really hot days or if you have an awning up on the vent side: REMOVE both top and bottom vents completely, this increases critical airflow around your fridge by 25%. Open the awning to increase air flow to its maximum. If your fridge is on the sunny side, try shielding the vents with shading. Do not cover the vents.
