    Dometic AES fridge buzzing problem.

    HI we have the above fridge the large one with separate freezer. When driving on battery it has suddenly started buzzing after about ten minutes as if a relay is chattering. So we have to switch it off while driving then remember to switch back to gas. Which for short hops will be ok but a long drive will be a problem for the fridge. And it is difficult to duplicate whilst stationary
    Has anybody had this happen to them and found a solution?
    The van has started to hit back as we have just decided to buy a newer one with bigger payload and loads of things have started going wrong.
    Hope somebody can help.

    If it's the older 7 series mine had a 30 amp automotive relay on the back at low level which switched the 12 volts from the alternator

    Thanks Andy, the buzzing seems to be coming from behind the control panel at the top of the fridge not from the back. There may be a relay on the board on there which is emitting this high pitch buzz.
    Really wondered if anybody had experienced and found a solution.
