bucko1 Posted July 2, 2023 Share Posted July 2, 2023 we have a thetford n3150 fridge freezer,it works perfect on gas and battery but stopped working on electric, showing as code 8 on lights, we changed heating element and it worked for 2 days then stopped again showing same code, checked all wires got it working for 1 hour then it stopped again now cannot get it working at all still showing as code 8 on lights, would this mean element has packed up again or does powerboard need changing does anyone have any clue as to what is happening here tnx in advance Quote Link to comment Share on other sites More sharing options...
Ninian Posted July 2, 2023 Share Posted July 2, 2023 Hi, According to a video on Youtube if you have continuity with the element, you require to change the power board. Look at Youtube Thetford Code 8 problem. Quote Link to comment Share on other sites More sharing options...
onecal Posted July 2, 2023 Share Posted July 2, 2023 Check you have an electric supply to the unit and all connections, check your heater element , replace if faulty if not check the power board and replace if faulty . Regards Quote Link to comment Share on other sites More sharing options...
Labby Posted July 2, 2023 Share Posted July 2, 2023 I believe that the power board on the rear of the N3150 has a fuse in it that is linked to mains operation and fault code 8 which may be worth checking. Quote Link to comment Share on other sites More sharing options...
onecal Posted July 2, 2023 Share Posted July 2, 2023 Yes fuse should always be checked with a full connections check along with ensuring a supply Then the heater element and if they are all operational the power board needs some scrutineering or replacement Quote Link to comment Share on other sites More sharing options...
