Hello, we just took delivery of our expanda and are packing all our stuff into it ready for its first trip. I have hooked the power up but can't seem to get any response from the fridge. I definately can not hear it running (a good thing i guess) but I have it on 240v and it does not seem to be be getting cold. I read in the instructions that the dometic sometimes requires being run for 4 hour prior to using. Has anyone had similar issue or is this normal and i need to be patient? Also the b2200 heater seems to stuggle, again I have read that it only takes the edge off, is this also right? Thanks
