It would help to know the full model number and whether the oven is actually cooking by itself when you close the door, or if just the fan, light, and/or turntable is running when you shut the door.

But either way, the first place the start is with the door switches and mounts. My help file on those is here.

If those are good, it may need circuit board repair.

This is normally 1 of the interlock door micro-switches not working.

SOURCE: Buzzing noise, wont work???

The magnatron is shorting, overloading the high voltage transformer. From the picture this looks like an older unit and is probably not worth a magnatron replacement.

SOURCE: Microwave oven runs with door open

This is usually caused by either a bad door switch, a loose door switch mount.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

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.

If you 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: http://tinyurl.com/yzjozk

Replacing relay switch in electrolux high speed microwave oven


Sometimes a door latch or magnet closure is a problem. If the door fails to make proper contact when closed, the oven will not start. If the oven goes on and off, there is a disconnect and in some cases the rotating glass dish inside vibrates and causes a disconnect also.

Unit starts automatically when door is closed


please review this and fix it. God bless you


  1. Interlock switchIf your microwave is turning itself on, the first thing to check is the interlock switch. This is usually the first thing to malfunction that could cause this issue. If the interlock switch is bad then it will need to be replaced.
  2. Main control boardIf your microwave is turning itself on and the interlock switch is still working, the probable cause is the main control board. If the control board is defective it will need to be replaced.

I ordered and received a replacement door for my 2002 spacemaker ge microwave. The lady I spoke with said I would be able to install it myself. I figured there would be directions in the box explaining...


HELLO.

Below is the solution to replace your microwave door.

Unplug the oven from the outlet and/or shut off the gas valve. Open the old door completely and unlock the hinges by pushing the hinge out toward you and down toward the door. Slightly close the door and lift the door up and toward you.


Install the new door. Make sure the wall oven door hinges are aligned to go into the rectangular wall oven slots. Place the hinges into the slots. The hinges should "catch" on the slots comfortably.


Ensure the door is fully opened and push the hinge locks into an upright position. The two hinge locks should rest on top of the two hinges that are inserted in the wall oven slots.


Close the door and open it several times to make sure the door is properly opening and closing. Replug the oven back into the outlet and/or turn the gas valve back on.

Thanks.

Power comes on but at the end of the cycle nothing is cooked


Please check the door safety interlock switches. These are the micro switches inside the case that tell the oven the door is closed. When you open the door while the oven is running, there is an arc on the contacts in the switches and they burn a little. After a while, the switches are no longer able to report the door is closed. When the door is not closed, the heat is not turned on. Forget what you know about the door being closed.

Check the switches.
