I've got a '77 Sovereign
with the original RM100 fridge in it. It sorta works, but sometimes it takes a day or two to really get cold. I've got the service manual for the trailer, and it talks about cleaning the flue regularly, but doesn't really show or explain exactly how to do it. I know it hasn't been done in the 5 years that I've owned it, and who knows before that.
Is there anyone who can describe in simple terms, exactly how to clean the flue? Maybe someone has some pictures posted somewhere? Any other maintenance suggestions would be welcome too....
