I have a GE microwave model number JES1290ML01. The lights

This answer was rated:

I have a GE microwave model number JES1290ML01. The lights came on and the turntable turned, but nothing was happening. I replaced 2 switches (the bottom 2) where the door shuts, and now I get a message saying the door is open. How do I fix that??? there are 2 more switches at the top of the column the switches are on. Do I need to replace them too?
Thanks for counting on us to help with your appliance problem. My name is XXXXX XXXXX I look forward to helping you! Are you certain you got the wires back on the switches correctly?

There were 2 wires on one switch, 3 on the other. They can only go on one way, so yes, I am sure I put them back the same way they came off.

The one with three wires is the one I would question. What color wires are on that switch, please?
Customer: replied 3 years ago.


I would have to open up the microwave again. Give me a few minutes. Do you want a picture of the "column" I am talking about too? Might as well while I have it open.

On that switch, there should be a blue, gray and white wire. The white oges on CO, blue goes on NO and gray goes on NC, is that how you have it?

Here are pictures of 3 of the switches.

Here is the top switch

It looks like the switch with 3 wires are white, blue and grey, but they have big things on the end of them.

Okay, so all those connectors are set, you can't miswire. That only leaves the top switches as suspect or the latch is not actuating them with the door closed. Secure the latch assembly back in place and close the door. Does the door actuator make contact with the door switch buttons?
Customer: replied 3 years ago.

What is a door actuator? The little hook thing that keeps the door latched?


They do make contact, but the bottom switch facing the outside will engage, but does not disengage when the door is shut. It's like ringing a doorbell; you push it in and let it out an the bell rings. This only pushes in and holds it. I'll put it back together and see if I can get another picture. Would that help?

All the switches should have their "plungers" or little buttons held in when the door is closed. Is the switch moving when the door latch comes down?
Customer: replied 3 years ago.


yes. It is held down when the door is closed.

Okay, so all switches are?
Customer: replied 3 years ago.


Yes, as far as I can tell, all the switches are held down when the door is closed.

Okay, so that only leaves switch issues. I believe replacing the other switches will correct the door issue.

And if it doesn't? Is there something else I should check out?


 

There really is not anything else if the wires are correct, which they are, and the switches are getting actuated. The control could do it, but usually does not fail like this.
Customer: replied 3 years ago.


OK. Thank you for the information. I hope the switches do the trick or I will be shopping for a new microwave!


 


Enjoy the rest of your summer.

Thank you, XXXXX XXXXX well! Let me know how it goes!

It didn't go well. I replaced the 2 other switches, and they keep shorting out the fuse. Now nothing works.


 

One of the switches is wired incorrectly, the monitor switch. It is the middle switch, shown in the picture below. Are there two or three wire terminals on that switch and which wires do you have connected (color)?

2 wires, black and white with a blue plastic shield over it. The black one goes in the middle of the switch, the blue one goes on the post sticking up.


 

Is the switch like the one below and the wire terminals in the same place?

yes, same switch. There are 3 like that, and one with 2 prongs at the end.


 


The middle wwitch is the one that is shorting everything out. I tried replacing it with an old switch, and it did the same thing. Before I replaced the middle and top switch, I would get a message saying the door was open. Now it shorts out, even with the original switch in there. Why would it do that?

The schematic shows the wires on that switch as black and white. Could you have miswired it?
Customer: replied 3 years ago.


No, tried it both ways with the same result. Could there be anything else that would cause that switch to short out the fuse?

No, let's look at the other wiring.

The top switch should have a white/black double wire and a red/red double wire to it.

The middle switch should have a black and white wire to it.

The bottom switch should have a gray and a white, black double wire to it.

There is also a secondary switch that should have a blue and a green wire to it.
Customer: replied 3 years ago.


That is how it is all wired. I currently have the middle switch disconnected though, but I know how the wires go in.

Okay, so it blows the fuse when plugged in or when?
Customer: replied 3 years ago.


as soon as you plug it in

Okay, and not if you disconnect which wires?
Customer: replied 3 years ago.


correct

Which wires can be disconnected so it will not trip the fuse, sorry?
Customer: replied 3 years ago.


The black and white ones, on the middle switch

So what is happening is that the middle switch is it is closed when it should be open. Can you test that switch for continuity with the door closed and the wires off?
Customer: replied 3 years ago.


What do you mean by test for continuity? With a meter? I won't have one until after work tonight. What would I be looking for?

We just want to see what that switch is doing. When the plunger is down, those wires on that switch should not have any contact with each other. There are markings on the switch that say CO, NO & NC. The wires should be on CO and NC, are they?
