How can I fix my fridge. Type C40/110. Modal RM 7291L ?

We have a 2004 Senator Wyoming with a Domestic power fridge, Type C40/110. Model RM 7291L. Some months ago we could only get the fridge to work on a small part of the thermostat, now it will not work at all when switched to 240 volt and the 240v indication light dose not come on. The circuit breaker is ok. Is thear anouther in line fuse. Can I get circut drawing for it and if a new part is needed can you tell me best place to obtain it. Many thanks for any help.
