How can I raise the door on my fridge?

How can I raise the door on my hotpoint mistral ff. The temperature light is on. Initially I thought it was because it wasn't shut properly. I can still hear the motor running. The outer skin of the fridge is warm and so is the inside. The freezer appears to be working normally. I've looked at other responses and it does appear that my door has dropped slightly. I've tightened up with a wrench but I can still lift the door slightly.
