I have a motorhome with a 3 way Thetford fridge/freezer

Customer Question

Hi Pearl, I have a motorhome with a 3 way Thetford fridge/freezer however it will only run on hook-up 240v, it won't run on battery or gas. I have replaced 2 fuses but is there a 3rd behind the outer vent and if so where and what type?
JA: Who makes your fridge? How old is it?
Customer: It's a Thetford fridge and is 2.5yrs old
JA: How long has this been going on with your refrigerator? What have you tried so far?
Customer: I noticed the issue on Wednesday, I have replaced both the F2 and F4 fuses but still the same issue
JA: Anything else we should know to help you best?
Customer: I have tried the switching off, selecting the different modes both through Gas and Vehicle but still flashes red and flashing display

Thank you for the picture.Please can I have the exact model of your fridge.Thank you

If you encounter error 3,please check the gas bottle if it is empty or the valve is shutt-off.

If you can't connect to battery,make sure the engine is running and check 12V fuse in the fuse box of your motorhome.

These have been checked Mace and of course the engine was running when tried. I initially asked in my query if there was a 3rd fuse within the outside vent, I have already replaced 2 of the inner fuses.

Please can you give me the exact model of your fridge so that I can check here in the diagram.Thank you.

Try to watched this video.But In doing this you must have a experience in disassemble and use of mulitmeter. There's also a fuse inside the control board. I suggest to look for a experience technician.
