have you been and done a big shop ?
the temp in the fridge is getting to warm (turn the thermostat UP).see if neighbours will hold your food until you get the light to go off, you may have to have a surprise party to use up the food if no improvement.
the fridge itself could have broken down, gas leak, compressor failure,thermostat failure etc .
need to call a repair man,(get a repair cost estimate)
need to buy another fridge
