My lg fridge freezer GR-L197WVS was making a rattling no ice and now the bottom half of the fridge is freezing and the lights on the front panel have all gone out except for two on the freezer side where there should only be one lit up? If we turn the complete unit off then after a while back on then all the lights will go back on correctly for five mins and then they switch off again and go back to what I have written above? How can I fix this, what is wrong?
