Have had my MH for 3 years now and had no problems with fridge. Came home after a week with no problems and went to turn off. Whilst switch rotated to the off position light remained on. After a bit of fiddling got it to switch off but now will not switch on in any combination of gas/12v/240 volt. Both this switch and the temperature control switch do not appear to be making contact as they rotate very freely. There are no signs of the fridge moving, however is it possible for the pcb to have moved away from the controls? Having downloaded the manual to see if the above could be determined from photos, which it did not help, I read the installation instructions that made specific detail of sealing fridge from interior. When parked with the fridge vents facing the wind an absolute gale blows in which now starts me to question if it has been sealed properly. Will have a look today but would ask should this happen and should I consider contacting the original manufacturer?
