I'd say under the CGA, an oven should last more than 8 years (but probably not a huge amount more).
Parts should certainly be available.
I would be asking them what they plan to do to remedy your situation, reminding them of the fact it was a $2000 oven and you expect resolution under the CGA. You actually have a case against the retailer you bought it from. They are the ones who legally have to sort it.
Disputes tribunal filing would be the next step.
It's not a Parmco is it? we had one, same size, same price. It crapped out a few times (overheated the switch mechanism/circuitry for the oven function selection). They provided the parts to fix it three times (one of which we paid labour for). After 8 years, we gave up on it and bought a Bosch. They would have fixed it again, but it would have just died again, probably when the head chef was in the middle of cooking something very important (not just my dinner ;) ). Parmco were however, pretty good to deal with. They seemed to understand the CGA, though I saw on Fair Go a few weeks back an issue with a Parmco Oven, which only after getting Fair Go involved they refunded.
Ppfftt... the oven in my sons flat it probably 40+ years old. For an expensive oven I would say 15-20 years is easily realistic.
We should be demanding LONGER warranty periods, LONGER life expectancies , LONGER serviceability periods. The ONLY people who benefit from this throw away society are the shareholders. If you want to make a product that can not be fixed, then it best come with a LONG warranty. I spent many days fixing toasters, kettles, irons, etc during my apprenticeship and parts were easy to come by.
