Symptoms

  • Visible crack, chip, or missing piece in the glass plate
  • Plate may wobble or sit unevenly because of the damage
  • Damage may have come from a dropped dish or thermal shock
  • Turntable motor and roller guide otherwise work fine

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

  1. Stop using the cracked plate, since a further crack could shatter and create sharp fragments near food.
  2. Carefully remove the damaged plate, wearing gloves if there are any loose shards.
  3. Check your model number and order a direct replacement turntable plate, which is a widely available and inexpensive part.
  4. 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.
  5. Once the new plate arrives, simply set it onto the roller guide and drive hub as the original was positioned.
  6. This is a simple swap that doesn't need a technician.
