Thanks Bill, I think your right with the Danfoss compressor controller and the alarm code could be L1 or something similar, I only saw the code for a moment then it switched off and would not switch on again. I’ve checked the wiring as far as I can see with no issues sighted. I’ve swapped the IR33 thermostat from the fridge and although it illuminates it does not switch the freezer on.
I will check something’s tomorrow from your information, but I have a good local mechanic that will visit Monday and figures it’s a sensor issue if it’s the L1 code which he’s familiar with.
Thank you as always for your attention and helpful information, I’ll let you know how I go

Frigoboat refrigeration with Danfoss Compressor controllers have an error code of 1 Flash from a LED across the "D" terminal and a "+" terminal on the
Danfoss Compressor controller. This is a low voltage alarm, and is a highly reliable indication of a battery bank, wiring or connection issue. This alarm does not lie. If you have this alarm, you probably have a wiring or connection issue somewhere. I am sure that your Frigoboat has a Danfoss controller.
The part you are describing is, I believe, the Carel IR33 Electronic Thermostat. I checked the manual on this thermostat and see no error code 1. I believe that the Carel IR33 Electronic Thermostat could be used with any Frigoboat system. Maybe it is possible that this Carel IR33 Electronic Thermostat is relaying the Danfoss error code. I don't know, but if it is capable and is doing so, the solution is in the first paragraph. I have attached the Carel IR33 Electronic Thermostat manual for your convenience. Please let me know what you find.
