Likely causes
- CommonImpact damage from a dropped dish or utensilGlass turntables can chip or crack if something heavy is set down hard.
- PossibleThermal shock from extreme temperature differencePlacing a very cold dish on a hot plate, or vice versa, can crack glass.
- Less commonAge-related wearRepeated heating cycles over years can weaken glass slightly.
What to do
- Stop using the cracked plate, since a further crack could shatter and create sharp fragments near food.
- Carefully remove the damaged plate, wearing gloves if there are any loose shards.
- Check your model number and order a direct replacement turntable plate, which is a widely available and inexpensive part.
- In the meantime, avoid running the microwave without a turntable plate in place, since this can cause uneven heating and in some models isn't recommended by the manufacturer.
- Once the new plate arrives, simply set it onto the roller guide and drive hub as the original was positioned.
- This is a simple swap that doesn't need a technician.
