The right side wall cover plate is the "waveguide cover."

It protects the waveguide and the magnetron at the other end from moisture, grease, and food particles.

If these remain stuck to the waveguide cover, arcing can occur, which will damage and / or destroy the cover, the waveguide or even the magnetron or the oven chassis.

As with most problems, this should be addressed sooner rather than later or it will only get worse, and may become unrepairable.

The similar Sharp model R-530E-series service manuals are here and here. They will help with disassembly, but the external / cosmetic parts will not interchange.

The Wolf waveguide number is 801798 and Wolf part ordering information is here.

The oven cavity and waveguide must be clean and if any spot is scorched or chipped, it must be sanded smooth, cleaned and dried, then touched up with appliance paint, available from local big box stores, home centers, appliance parts stores, and hardware stores.

Leave the door open overnight to dry the paint. Then install the new waveguide cover.

If the chassis or waveguide have holes in them, the oven must be scrapped and replaced.

For more free DIY and other help & advice, feel free to contact me via my site.

Please include FULL model number*, FCC ID number*, + detailed symptom information. ( * on the tag in cooking cavity or around door frame or control frame or on back)

SOURCE: wolf - microwave oven not turnin ON

This is usually caused by either a bad door switch, a loose door switch mount (which are pretty simple problems to fix) or occasionally a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Chances are you had a grease splatter onto the cover and it caught on fire resulting in a hole. The part is called a wave guide cover (#5526 on Diagram) and you can get a replacement part at http://www.searspartsdirect.com/partsdirect/part-model/JES1384SF?sid=MMLxMerchandizexManualsModelxJES1384SF%20GExJES1384SF

Hi,

The problem is in the door switch.... when the door is tightly closed the switch is not making contact but if you push that button and the door opens just a bit then the switch makes contact and it works....

If you can get a new door switch for that and replace the door safety switch then it will work for you...

All you need is a new WaveGuide Cover. It is fitted with usually a screw or plastic clip and is fitted from inside of the cavity, where you place your food to be cooked. No taking anything to bits, just the cover.

If you were to log on to the manufacturer's web site, I think you will be pleasantly surprised as usually one is able to download, by model number, Customer Instruction Manuals, list of Dealers for spare part supplies as required.

The information is normally free of charge.

I hope this helps.

Wolf Microwave model MW24. How do I repair door problems?


Microwave doors are very important have contact switches that switch off if open or damaged. Interfearing with the door could lead to serious injury. The best way to sort doors tha wont open or close is to replace with old doors of the same make that does not have the same problem.

What is the silicon plate? On the inside of yhe machine


James,
Actually it is a silica cover plate, and it is usually mounted on the wall on the right side of the cavity up near the top. It covers the tube that goes back to the magnetron. It can occasionally get food particles behind it which can cause holes to be burned through the cover. A periodic wiping down of the inside should help in preventing problems like that. Hope this helps!

I would like to fix a door switch on wolf MW24


The adjustment does not last, the technician should have replaced the door switch from the beginning to avoid a callback and leaving a bad impression. To trouble shoot you will need a digital meter, if you have one one post back.

I get an occasional spark when microwave is in use


Presuming that you have iliminated the possibility of any metal objects that are not meant to be in the machine being in there (and this includes dishes and other items with silver or gold leaf on them, which WILL spark and burn!) then take a look inside the oven its self. You will find a waveguide cover. It is usually a strange flakey silvery plastic/card like material called Mica and is usually on the same side of the microwave wall as the control panel (So if the picture on this thread is accurate, I will guess the Mica cover is on the right hand wall inside as you look at the machine from the front) . Over time, the magnatron (the thing that creates the microwave energy) will often burn a hole through the mika, or cause a dark brown or black burn mark in it. If this cover is even slightly damaged then it may well cause sparking inside the machine. These covers are designed to be removed and you can buy replacements for them from electrical stores.

The top plate inside the microwave sparks while cooking. We checked the dish we were cooking with, the papertowel that covered the dish. What could be causing this?


The wave guide could be dirty or damaged. Dirty oven interior can also cause sparking. The wave guide is probably not dirty if it's not on the interior of the oven . Some are behind the interior wall .
