Smoke is comming out of the stove when the oven is on

it is something that I would seriously investigate

We bought a new stove!

Are there fuses in this stove. There usually are in most electric stoves Quite often in the back behind the clock if there is one..
You may have blown a fuse.

All you have to do it wait and it will unlock itself. It just gets very hot so the stoves are made to seal themselves until cool!

Nothing in the elements, thermostat thermocouples are gas filled, sensors have wiring inside, nothing in the liner or insulation. You said this was a stove, and some stoves have a vent that goes up through one of the burners on the top. If you had oil splatter or drip into this it can get into your oven. We do know that some blower fans on convection ovens have a sealed oil bearing, but there would be very little oil coming out of this (drops) and you will notice your fan getting noisier or running slower in the near future. Good Luck, Appliance Specialists

fryed switch or fryed burner
if smoke came from inside stove likely the burner is fryed
try setting oven to broil and see if it heats up
if it does replace lower burner

on the oven's smooth surface you should use a razor blade and scrap off the plastic (when cooled).. if the plastic melted on the burner, you may need to replace that particular element from a local appliance part store. easy to do.

soundsas if you have a dirty stove, Id reccommend running through en extended cleaning cycle, it will SMOKE, that s geting rid of any food/grease trapped inside the flue and cabinet of unit

I found that the 220 plug had burned out, that was where the smoke came from. The display worked because the ground "prong" was the only one burned. Had to replace the electrical 220 socked and the electrical plug on the oven.

Locate where the smoke is coming from first. Run a dry test with just the stove. Many times excess smoke can be either oven cleaning chemicals burning off, or debris on the elements.
