New oven still puts out terrible odor 5 days after buying? I recently bought a new convection oven/microwave/grill combo made by Sharp. The user manual said for first time use to run the convection oven at max heat (230C) for 1 hour, which produced a verybad odor but I felt like this was normal. Now, even 5 days later, after cook several frozen pizzas/french fries/bacon and other good stuff, the oven still produces a bad odor when in use.

Can something be done about this or should I expect it to go away after some more time?

Here's the exact oven combo if you're curious, https://sharp.vn/vn/index.php/thiet-bi-gia-dung/lo-vi-song/dong-dien-tu/299/r-c951dvn-st-1-detail
It is a normal experience that every time you use a new appliance with a heating device, you will smell something weird like burning plastic. I recommend you to read on the link below on some tips of getting rid of chemical residue (smell) from your new oven.

If this is not effective, try my experiment which did a great wonder. Pour some water into a pan and add a teaspoonful of cinnamon powder into it, put inside the oven and set it to 250°C. You may also use a tablespoonful of vinegar as a substiyute.
