What is the most common problem with a broken fridge?
assume broken in your word means fridge does not cool at all?, check if the power plug is pulled out, this can confirm when you open the fridge door light should be on, then check the thermostat switch inside the fridge which has numbers or low cool mid cool high cool perhaps the dial switch is set very low without you noticing, if all is in order either you have lost all freon gas, or the motor has seized and you need a new fridge.
