Is it safe to use a microwave with the metal rack inside?
Short answer
⚠️Depends / use caution
It depends—some microwaves are designed to safely use the included metal rack, but only as instructed.
Context
Metal is usually unsafe in microwaves, but many units include a metal rack, causing confusion.
When it might be safe
- The rack came with the microwave
- The manufacturer instructions allow rack use
- Food does not touch the metal
When it is not safe
- Using loose or unknown metal objects
- Metal touching the microwave walls
- Running the microwave empty with the rack inside
Possible risks
- Sparking or arcing
- Damage to the microwave
- Fire risk if misused
Safer alternatives
- Remove the rack if unsure
- Use microwave-safe glass or ceramic dishes
- Check the appliance manual
Bottom line
Only use a microwave’s metal rack if the manufacturer explicitly allows it.
