Smeg Microwave Wave Guide Cover - 140mm x 140mm

The wave guide cover is a small plate inside your microwave that protects the wave guide (which directs the microwaves into the oven cavity) from food splatters and arcing. It's crucial for safe and efficient operation.

The wave guide cover typically needs replacement when it becomes visibly burnt, cracked, or shows signs of damage. This can vary depending on usage but is often due to prolonged exposure to microwave energy and food debris.

Verify your Smeg microwave model number against the list of compatible models provided in the product description. The dimensions (140mm x 140mm) and fixing centres (125mm x 125mm) are also key indicators.

While generic covers exist, using a genuine Smeg part like this one ensures the correct fit, material quality, and performance designed specifically for your appliance, minimizing risks.

This wave guide cover is made of mica material, which is a common and suitable material for microwave oven wave guide covers due to its insulating properties.

Replacing the wave guide cover is generally a simple procedure that most users can perform with basic tools, usually involving removing a few screws or clips.

Check if the wave guide cover is damaged or burnt. A severely damaged cover can prevent the microwave from functioning. Ensure the cover is correctly installed. If damaged, replace it with a new one.

This is often a sign of a damaged wave guide cover or metallic objects inside. Ensure no metal is present, and if the cover shows signs of burning or damage, replace it immediately.

While not always the cause, a worn or improperly seated wave guide cover can affect microwave energy distribution. Ensure the cover is clean and correctly fitted.
