Question 1

The fridge isn't cooling well enough

Accepted Answer

Possible cause: Inadequate ventilation, thermostat set too low, condenser heavily frosted, too much warm food stored recently, or the unit has only been running a short while. Check the ventilation grilles aren't covered, set the thermostat higher, check the door closes properly (clearing frost), let warm food cool before storing it, and allow at least 4-5 hours' running time before judging performance in ambient heat.

Question 2

The fridge won't cool while running on gas

Accepted Answer

Possible cause: An empty gas cylinder, a closed upstream shut-off device, or air in the gas pipe. Change the gas cylinder, open the shut-off device if closed, or switch the appliance off and back on (repeating 3-4 times if necessary) to clear air from the line.

Question 3

The fridge won't cool on 12V power

Accepted Answer

Possible cause: A blown on-board fuse, a discharged on-board battery, the engine not running, or a defective heating element. Fit a new fuse, check and charge the battery, start the engine, or - if the heating element is defective - contact Dometic Customer Services.

Question 4

The fridge won't cool on 230V mains power

Accepted Answer

Possible cause: A blown on-board fuse, no mains connection, or a defective heating element. Fit a new fuse, connect to a mains power supply, or - if the heating element is defective - contact Dometic Customer Services.
