Remember in Australia, if you’re persistent enough, you could get this replaced under Australian Consumer Law, if something breaks in an unreasonable amount of time (outside of warranty, even). Considering fridges can easily last for 10 years, anything well within that should be fairly easy (but require many, many emails and threatening to taken them to your local small claims) to get replaced.
That is if you can do without a fridge in the meantime 😅
