Hi,
I have a Parmco oven - AR900-LEG.
It developed the exact same fault, at about 6 years.
The issue with ours is the mechanism behind the function selection knob - it had overheated and needed replacing. The elements etc were all fine. Yours sounds the same (ours would only get to 100 degrees or so on one of the functions). Weird that Parmco say they haven't got the parts. They certainly had them for ours (and this was repaired in November last year).
Interesting you say that, I found this on another forum also:
On the subject of Parmco ovens -
Our property has one (purchased by landlord). For a while it had been failing to properly heat up when using any of the bake settings. Grill would work fine. Then the timer knob failed, the spring had come loose. Parmco sent out a 'technician'. He replaced the knob but we still had problems with it heating up. Landlord called out a different tech and found that the entire portion behind the timer knob (wires and all) had melted and was shocked the entire unit hadn't caught fire.
Several people with the same fault, mostly caused by overheating behind the control knobs. Sounds like a design fault and a potential safety issue. Maybe I'm being a bit OTT, but is it worth a mention to the Energy Safety http://www.energysafety.govt.nz/about/external-organisations-links/product-recalls-and-general-product-safety
