Westinghouse WBB3400WA (White) Questions & Answers

Well the last time my fridge was playing up freezer still cold as but the fridge wasn't, it turns out it was my thermostat and it needed replacing. Only other way I can think of is that it might need regassing. But I would ring around and get a quote from a fridge technician.

This is all I could find, hope it helps :)

I don't know what State you are in but in Victoria Consumer Affairs still believe you have a right to warranty even when it expires (not years after) but months certainly
https://www.consumer.vic.gov.au/businesses/fair-trading/guarantees-warranties-and-refunds/goods-covered-by-guarantees/when-are-goods-covered-by-guarantees
from that web page
"Acceptable quality" Which means you would assume that a fridge should last quite a few years (not just until it is out of warranty)
All goods supplied to consumers must be of “acceptable quality”. They fit this description if they are:
fit for the purpose for which they are commonly supplied; that is, they do the job that type of thing is usually used for
they will be safe, durable and free from defects, and
acceptable in appearance and finish.
So get in touch with Westinghouse, tell them what is wrong, if they don't want to know about it, get all the particulars of who you are talking to etc etc etc. Tell them you are
going to Consumer Affairs. If that doesn't get a response contact CA with all the details and they will contact Westinghouse on your behalf.
