Why is my fridge making a loud noise and building up ice?
A noisy refrigerator with ice buildup is often caused by a freezer door not closing properly or ice blocking the internal fan. Melting the ice with a hair dryer only provides a temporary workaround and leaves users guessing how to properly stop the low temperature warnings and continuous buzzing.
