- Product typeGadgets
- Withstands 500 °C continuous heat for reliable microwave repair

Replacement Mica Sheets for Microwave Ovens
These mica plates serve as direct replacements for the waveguide cover found inside microwave ovens. They address arcing or burning around the magnetron chamber caused by food splatter igniting on the original cover. The sheets restore safe operation by shielding the magnetron opening from debris and moisture.
Customisable Dimensions for Universal Fit
Each sheet measures 200mm by 200mm with a thickness of .2mm, providing enough material to cover most microwave magnetron chambers. Users measure the existing opening and cut the sheet to the exact size required using scissors or a craft knife. This flexibility allows the same part to fit various brands and models without needing model-specific components.
High-Temperature Insulation and Easy Installation
The mica material withstands continuous temperatures up to 500 Celsius and intermittent peaks of 850 Celsius, maintaining electrical insulation under normal cooking conditions. The rigid yet lightweight sheets slide into the existing slots or grooves that secure the original cover. No adhesive or tools are required beyond cutting the sheet to shape.

Questions about this item
How often should the 0.2 mm mica sheet be replaced once food splatter starts burning on it?
Replace the sheet whenever burnt food creates a hole or conductive path; the 200 mm x 200 mm sheets can be trimmed to fit any magnetron chamber.
At what temperature does the mica plate reach its continuous-service limit during extended microwave use?
The material is rated for 500 Celsius in continuous service, so sustained heating above that level will degrade the sheet first.
How hot does the mica plate get when the microwave runs all day?
Intermittent service rating is 850 Celsius; under normal daily use the plate stays well below the 500 Celsius continuous limit.
