it smells like burning plastic the first few times i use it, even after doing the empty burn-in cycle, is that safe?

Diagnosis

That's normal for the first 2-3 full-heat cycles. It's manufacturing oils, adhesives, or minor dust on the heating element and internal components burning off—not the plastic housing itself.

How to Fix It

Run the unit empty at 400°F for 20 minutes in a well-ventilated area (open windows, turn on hood fan). The smell should significantly diminish each time. After this, cook something with a strong, pleasant odor like lemon slices or bread to help mask any residual scent.

If That Didn't Work

If the plastic smell persists beyond 3 cycles or is accompanied by visible smoke or melting, immediately unplug. Check for and remove any non-removable plastic shipping film or protective stickers you might have missed, especially on the heating element area inside.

Heads Up

Never leave the room during these initial burn-off cycles. If it's actual plastic burning (acrid, thick smoke), there could be a faulty component. In that case, stop use and contact support.
