If you need an LED for the fridge, you're leaving the door open for too long. If you insist, wait until the existing incandescent burns out; otherwise, the time spent with the door open changing the bulb will probably waste more electricity than you'll gain from running the LED bulb for the rest of the lifetime of the fridge.
