Microwave turntable glass plate cracked, chipped or missing (all brands)

A cracked, chipped, or missing turntable glass plate is one of the few microwave issues that’s both genuinely common and completely safe to sort out yourself, since it’s just a removable accessory rather than a fixed internal part.

What to check and do

• Check whether the roller ring underneath (see our separate turntable guide) is also affected — sometimes a chipped plate is caused by the roller ring sitting incorrectly, and it’s worth checking both together.
• Order a genuine or compatible replacement glass plate for your specific model — these are inexpensive and widely available; measure the diameter of your existing plate (or the guide ridge inside the microwave floor) if you’re not sure of the exact model.
• Don’t run the microwave without a turntable plate fitted at all on models designed to use one — food won’t heat evenly, and on some designs running without it can cause other problems.
• Never use a plate that isn’t specifically designed for microwave use as a substitute — regular glass or ceramic plates aren’t necessarily microwave-safe and could crack, or in rare cases contain materials unsuitable for microwave use.

When to call an engineer

This one’s rarely a call-out situation — a replacement plate is a straightforward, inexpensive DIY part. If the roller ring or turntable motor itself is also damaged, see our separate turntable-not-turning guide.
