I own a Hoover fridge freezer. I've been having problems with it for months, not freezing (the fridge being fine though). I called Hoover out at a hefty price and they replaced the fan. Seemed to work fine for a couple months, and now it's not freezing again. Is it likely to be the fan? Why would a fan keep going? Or could it be a different problem?
