Question 1

Refrigerator does not start

Accepted Answer

Possible cause: Not switched on correctly, the vehicle isn't level, or there's no power source available to start it.. Check it's switched on as per the instructions, that the vehicle is level, and that a power source is available. If it still won't start, get in touch with your dealer or your nearest Thetford Service Centre.

Question 2

Error Error code 3: The refrigerator won't run on gas.

Accepted Answer

Possible cause: The gas bottle may be empty, or a valve or shut-off valve may be closed.. Check the gas bottle isn't empty and that the relevant valves are open, then turn the refrigerator off and back on again. If that doesn't help, try switching it to a different power source instead.

Question 3

Error Error code 6 or 7: The refrigerator won't run on 12V.

Accepted Answer

Possible cause: The engine isn't running.. Confirm the engine is actually running, or switch the fridge over to a different power source instead.

Question 4

Error Error code 10: The refrigerator won't run on 230V.

Accepted Answer

Possible cause: Mains power isn't available.. Check whether mains power is actually available, or switch the fridge over to a different power source instead.

Question 5

Error Error code 11: The refrigerator won't run in Auto mode.

Accepted Answer

Possible cause: The power sources aren't connected.. Check the sources are connected, or try running the refrigerator manually on one power source.

Question 6

Error Error code 18: All the symbols on the fridge control panel light up at once.

Accepted Answer

Possible cause: This is normal during start-up.. Wait a few seconds - the refrigerator should return to normal operation on its own.

Question 7

Refrigerator has insufficient cooling

Accepted Answer

Possible cause: Could be blocked ventilation, the vehicle not being level, too low a cooling level selected, the door not closing properly, or ice built up on the cooling fins.. Check the vents aren't covered, the vehicle is level, the highest cooling level is selected, the door closes properly, and clear away any built-up ice. If none of that helps, get in touch with your dealer or your nearest Thetford Service Centre.
