Smoke and a buzzing sound in an electric oven is typically a sign that the oven's heating element is going out. In this case, call a repairman to put in a replacement. This is one of the few times you can't DIY a smoke problem. If your oven is gas, it there may be too much gas pressure in the heating element. This can cause smoke, too. Check to see if the flame is reaching the oven racks. If so, call your gas company to see if your home's gas supply's pressure needs to be adjusted.

Smoke that comes from your oven only during self-clean cycles usually stems from food being incinerated under the excessive heat of the cycle. To reduce the volume of smoke generated by burning food during self-clean cycles, turn off the oven and let it cool completely, then wipe away wet food residue from the oven interior with a water-dampened rag and start the self-cycle again—this time at the shortest possible duration to prevent excessive heat buildup in the oven.
In electric ovens, smoke emanating from an oven during a self-clean cycle can also signal an impending short in the heating elements as a result of excessive heat buildup.
These elements are known to briefly buzz and produce smoke before failure. The easiest way to check if your heating elements are functional is to turn off the oven and then turn it back on. Replacement entails cutting the power to the oven from the breaker box and unplugging the oven, removing the screws and wires that connect the element to oven, and detaching the nonworking element from either the top or bottom of the oven.
Then, once the new part has been ordered, you can install it and re-attach the wires and screws before restoring power to the oven. In gas ovens, high gas pressure commonly results from an improper conversion of the oven from natural gas a fuel it was originally designed for use with to the liquid propane fuel type. Higher pressure can generate taller and hotter oven flames from the main burner at the bottom of the oven, which can, in turn, cause high volumes of smoke.
If the flame from the main burner meets or exceeds the height of the oven racks, the gas pressure is too high and the risk of an oven fire occurring during use is greater. Consult the oven installer or your gas company to safely correct the conversion—this should reduce the height of the oven flame and stop the oven from smoking. These are minor issues, so long as they are addressed swiftly. If your oven is starting to smoke for the first time in years, it's likely due to an accumulation of grease.
What if, however, you just finished deep-cleaning your oven, using a self-clean cycle or a chemical cleaner? Despite your efforts, this could be the culprit of any haze or that off-putting charred scent: There might be product residue causing a bit of smoke or even an unpleasant smell.
Tuck says this is especially common if you had a lot of grease in there to begin with. A dirty oven can ultimately prevent it from heating up to your desired temperature, resulting in unreliable cooking, wasted energy, and a reduction to the lifespan of your appliance—which is why Tuck says you should always clean up any spills as soon as your oven has cooled.
Of course, sometimes you need to get in there and give your oven a deep cleaning. To do this, Tuck suggests following a few simple steps. First, unplug your oven or shut the power off at the circuit breaker. Next, wipe down the exterior of the stove and oven, including the knobs and door gasket. You can soak burners and grates in hot, soapy water to remove residue.
