But when I got it there was also a dent on the side of it. What I want to know is, could there be a issue with, i.e. insulation being squashed? Peaking through the holes in the outer casing, there doesn't seem to be electronic bits in that area, just insulation. I don't want to burn my house down because of improper insulation (it's one of those pyrolytic self-cleaning ovens that cleans at 500 degrees Celsius.

This isn't really a sci.electronics.design question, so I've
cross-posted to sci.electronics.repair and set followups there. If it
isn't on-topic over there, they'll be able to help, anyway.

How big is the dent?

Cheers

The dent is about 3/4 inch deep in the left-hand side panel and about 2 inches of the bottom towards the front/door. It's just above the join with the bottom panel. It's about 20 cm long, with the deepest bit about 10 cm long. Seems like it was hit by a forklift. It came without the packaging, because that was damaged.

Nice price, good reviews:

I don't like the deep dent because (as you note), the lack of
insulation and the close proximity of the dent to the inside oven
wall, may conduct enough heat to the outside panel to start a fire.

Since you haven't installed it yet, tear it apart and try to pound out
the dent with several blocks of wood and a mallet. You can probably
get some assistance from the local sheet metal shop, HVAC ducting
builder, or anyone that deals in sheet metal fabrication.

A 3/4 inch dent implies that the metal has been substantially
stretched, so it may be necessary to cut out the damaged area, and
spot weld a stainless steel plate in its place. You can also just
slit the stretched area with rotary saw or grinder, flatten the panel,
and MIG weld the cut area closed. Since it's an insert oven, you'll
never see the patch job, so don't worry about cosmetics. It may also
be possible to purchase a replacement panel, but that's too easy and
no fun.

Thanks Jeff. I've now contacted Ariston and they will send out a guy to fix the dent. Once it's open I'll have a look at whatever is really behind that panel (hopefully only insulation) to make sure everything is okay.
