I has a similar problem with mine (4 years old, noisy, tripped the breaker, but also not cooling properly) and the cooling fan blade had separated from the fan motor. You can SEE the fan at the back of the freezer behind the slotted panel. If that's the problem, it's easier to relace the fan than it is to change the toilet paper roll. Empty the freezer, unsnap the plastic cover, unplug the fan motor, unscrew it, and replace. Just turn off the fridge first.

Tripping a circuit breaker (by any device) is an issue that is not easily (safely) addressed on-line. Besides an actual problem with the device in question, one must consider: a) Too many high current devices already on the circuit (toasters, microwaves, washing machines, etc.) that contribute/cause the issue. b) A circuit breaker that trips much more easily than it should (from tripping too much - common problem), and should be replaced.
c) The device in question needs the compressor replaced (very rare in a two-year old device), but can become damaged during shipment - on it's side. d) Damaged sub-component (eg. one of the fans), probably easily found by locating the source of the noise.
