Question about Jenn-Air JMC7000 Microwave Oven

1 Answer

Seal replacement? I think the seal on my JMC7000 door is leaking. There is condensation between the glass panels in the door and when cooking steam condenses on the cabinet just above the door. A moment ago the microwave shut off completely while cooking rice (as if the control electronics was faulty - or got wet?) with a blank display. After leaving the door open for a few minutes the display lit up again with no user intervention. I see from some online diagrams that one can replace the door seal: 1) Do you think this is the issue? 2) How do you remove and replace the seal if this is the problem? Are there clips holding it in place?

    The other thought I just had is that there might be an extractor fan that is not working?

It sounds like your cooling fan has failed, or possibly the relay on the control board. This same relay also runs the turntable. Is the TT working?

It's critical for the cooling fan to work, or the magnetron can overheat, which will cause the thermostat to interrupt power until it cools backs down. Sounds like what happened to you.

If it gets too hot or gets hot too often, it can be ruined.

A failed fan can cause such overheating and a buildup of moisture as well.

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

At our site, we have a video showing how to remove a typical over the range control panel assembly in under 5 minutes.

My y ovan glass was broken wher it was change


The glass front of the microwave is not important, as long as the mesh behind it is intact.

You may replace it at your leisure, or just ignore it.

To check your microwave for leaks, simply place a mobile telephone inside (do not switch the microwave on unless you are tired of the mobile telephone) and close the door. Ensure the microwave is plugged in. This will create a Faraday cage if the microwave is leak-proof.

Now dial the mobile telephone number. If it rings, you have a leak. Conversely, if not, there is no leak.

Happy cooking!

Door glass is lose and seal is leaking..moisture is forming on inside of glass


That is normally caused by the clear plastic adhesive cover either having been removed or missing. It covers the perforated door inner and stops condensation and food particles from getting inside the door cavity where is cannot be cleaned.

Condensation inbetween glass door on GE Spacemaker


Your glass seal has failed and I doubt it makes sense to replace the door. Yes, it can be dangerous as the moisture becomes worse you risk the chance the glass could over-heat and blow out. Sounds like you need to replace it, sorry!

Condensation marks on microwave door


For most microwaves the process is pretty straightforward. You can open the door and you will see the screws that hold the outerinside panel on to the glass. After you remove those screws you will see the screws that hold the ouside cover to the door in place. Once you get that far you will see what is holding the glass in place. Keep in mind to replace the gaskets around the glass right and anything you take off to get to the glass itself. If you are getting condensation from range top cooking then the seal around the glass may need to be replaced. You really cannot hurt anything by taking it apart, but it needs to be put back together exactly the way you take it apart. Good luck and hope this helped.

When the oven is cooking for over 5 mins part of the door goes a white opaque colour inside the door, it is as if the seal is broken and steam is getting inside the door itself.


That's probably what's happening, but it's not dangerous as long as the internal cooling fan is running and the screen / mesh between the door panels is not arcing or rusting.

It's suggested that you leave the door open for a few minutes any time you cook and notice a moisture buildup afterward.

Condensation betwejn the front door glass


This would require disassembly of the door panels, which is not recommended unless really required.

You can download the installation guide to help you troubleshoot and correct your venting issues. That should be priority one.

It may be a clogged filter, a bird's nest in the outlet, etc. etc. Failure to vent can cause control panel and keypad trouble if it continues.

GE XL1800 Door


OK, I'm no handy man and I just figured out how to do this. Open the door and remove the black plastic cover surrounding the inside glass. I used a regular flat head screw driver to pop this out.

Now I removed the 3 screws holding the inner panel against the glass on the front door. After removing the screws, the inner panel is held in place by a series of plastic clips. Go around the perimeter and pop the plastic clips out so the inner panel including the mesh comes out of the door.

Now you have complete access to clean the inside of the glass door!

I found it easier to do this operation with the door completely off the microwave, but you should be able to do this with the door in place too.
