Question about GE JVM1540SMSS Microwave Oven

1 Answer

Light cannot go off when door is closed

The detail model is JVM1540SM1SS, and model is DM 901366 U.

When I close the door, the light would not go off, so I cannot use it. I check the latches on the door, looks fine. Probably the switch is bad inside, I have no idea how to fix it by myself.

This is usually caused by either a bad door switch or a loose / broken door switch mount.

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 may be 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:.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

The model number to use is JVM1540SM1SS or just JVM1540.

There may also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

If you only need a switch, you can order a universal type from us for $5 postpaid.

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

There will be a simple switch fitted somewhere on the door latch mechanism. This has broken so the door is not registering as open or closed.

How do I fix the door so that it will close?


We would like to give simple questions, but not being able to investigate the door and the lock latches, makes it impossible to give an accurate answer. You really have to check the door and the parts engaged in the locking mechanism for that. Even placing good pictures of all the details would not make sure we could help.

Why won't my interior microwave light turn off and my microwave won't start?


It sounds to me that your door switches aren't working.Your oven is protected by a couple of switches that engage when you open or close the door.They control a couple of safety features and also your interior light.One of them seems defective.

some switches are normally closed "short position" press switch "open" it will be labeled NC on the one side, "stands for normally closed" and others will be NO "stands for normally open" press switch "short" if there is no change in readings when you press switch it is defective.

Underneath Light funtion stopped working on Kenmore 62642 model


We see this a lot. The problem is on the control panel, which we regularly repair nationwide for $39.95 postpaid.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.
