## Overview

This universal mica wave guide cover sheet (150mm x 100mm) is designed to protect your microwave’s wave guide entry from grease buildup and overheating. Easily cut to size with basic tools, it fits most domestic microwaves, enabling quick DIY repairs that prevent sparking and costly damage. Highly rated and trusted, it’s the affordable, practical solution to extend your microwave’s lifespan.

## Description

Sheet of wave guide cover material for all brands of microwave ovens. This mica sheet is usually found inside the cavity on the right wall or upper wall of the oven cavity. It covers the entry point that the microwaves enter the oven cavity. Fat and food splashes that gather on the cover over time cause the cover to overheat, burn and become soft. This can lead to sparking around the wave guide cover during the microwave cooking cycle. If this is not dealt with it can lead to the cavity being burnt as well. It is important to regularly inspect your wave guide cover for burn marks and replace as necessary. The sheet supplied is 150mm x 100mm which should be big enough for most domestic ovens. The idea is that you cut and trim this sheet to the size of your original cover. The material is easy to cut with a sharp knife or scissors. No special tools are required. If your old cover has a screw hole in it then a leather punch can be useful to make the hole. Otherwise the point of a screwdriver can be used to make the hole. Purchasing a universal sheet like this is often the easist option to obtaining an original cover as the originals can be expensive and in some cases difficult to source especially with all the strange brand names sold by supermarkets etc.

Review: Very good and easy to fit with care - This was very easy to fit provided you take time and do it correctly. I fitted this to my Whirlpool JT369 but this will fit most microwaves. Just measure the old one before you buy. You will save money by cutting to size to suit your particular microwave. Do not use scissors to cut the mica or it is liable to shatter. It is thin, it is meant to be thin. Best way is to remove the old one and use it as a template for the new piece. Use a flat protected surface to cut the mica. I used a chopping board on the kitchen table. ( I take no responsibility for you cutting into your wife's new table so make sure you protect it.) Place the old wave guide cover on on top of the new piece of mica and draw around it using a fine point marker pen. Make sure you also mark where the screw holes are. Now using a straight edge and a stanley knife with a brand new blade inserted, cut around the lines you have drawn. Be careful with the knife, again I take no responsibility for your trip to A&E to have stitches inserted. Once you have cut your new wave guide to size, use a sharp pointed object to make an impression where the screw holes would be. I used the tip of a very thin pozidrive screwdriver to do this. You could in fact use the screws to create the new holes before fitting. The screws on my microwave are self tapping screws so when I came to fit the wave guide back on it was fairly easy to enter the screws into the recess I made in the mica and start turning it with a screwdriver and it made its way through. If your screws are threaded then you may have to carefully drill a hole to size. Whole job took about 15 minutes to complete.
Review: Easy to use - Does the job, saved the microwave.

## Questions & Answers

**Q: Hi, does this item fit a tesco brand microwave.    It has two flaps on each side which slot in but not shown in your pic.  Does it have these? Thnx**
A: Hi,  yes you cut thisito shape with a knife or scissors.  Use your old  one as a template. Mine  has 2 slots in the metal frame of the microwave, I cut this to shape with to and slot it in no problem. ..quick and easy. At tge cost you have nothing to loseYou can cut thus to any shape so is ideal

**Q: Ive just drilled a 3mm hole through top of micro wave and punched through the inner casing.will this stop the waves leaking and what do i use to stick**
A: The inside of a microwave oven is metal. 
This panel allows microwaves to pass through from the emitter, while protecting it from heat and moisture. 
If you have created a breach between the inner and outer casing, your safest course is to cut off the cable and dispose of the oven properly.

**Q: My Google search was for "how to block microwaves" and this product came up in first place - However it seems this fabric does the opposite?**
A: The product goes in the oven to cover/replace the plate that all microwaves have in the side wall.  Quite what its function is I am not sure, but the firm were very helpful when I rang to explain that what I had actually wanted was a splatter guard to put over dishes in the microwave oven and I would suggest that you contact them.

**Q: Can this also be used over burning charcoal to warm rather than burn incense?**
A: I would say no. It’s more like a piece of card that fits, when cut to size, in slots in a microwave oven.

Does the job, saved the microwave.

### ⭐⭐⭐⭐ Easy fix provided you know how to replace it
*by S***H on 5 October 2021*

Easily fix your ovens when they have sparks, so that instead of throwing them away , just replace this cover sheet and its back and up running. Mines happened for the second time but everytime the sheet lasted for few years atleast. Worth the money.
