Question 1

Refrigerator's failure indicator LED flashes

Accepted Answer

Possible cause: There's no 230V supply reaching the unit, or the voltage is too low. Check the mains connection and site supply voltage.

Question 2

Refrigerator's failure indicator LED flashes

Accepted Answer

Possible cause: There's no 12V supply reaching the unit, or the voltage is too low. Check the vehicle battery and its connections.

Question 3

Refrigerator's failure indicator LED flashes

Accepted Answer

Possible cause: In gas/auto mode, the flame hasn't ignited. Check the gas supply and try again.

Question 4

Refrigerator's all temperature-setting LEDs flash

Accepted Answer

Possible cause: The temperature sensor is defective - the refrigerator will keep working on a mid temperature setting. The unit will keep running on a mid setting automatically; contact Dometic Customer Services to have the sensor checked.

Question 5

Refrigerator's failure LED plus all temperature-setting LEDs flash

Accepted Answer

Possible cause: The 230V heating element is defective. Contact Dometic Customer Services.

Question 6

Refrigerator's failure LED plus all temperature-setting LEDs flash

Accepted Answer

Possible cause: The 12V heating element is defective. Contact Dometic Customer Services.

Question 7

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 8

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 9

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 10

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.
