Microwave door My microwave door no longer stats shut on its own. I can hold it closed and the microwave works fine, however it doesn't click shut anymore. needshelp

You will have to remove unit from wall and inspect latch mechanism. Look for a broken spring.

replace the door hooks and door release button.
if this is broken the switch will not close very well, and NOT start the microwave.

God bless you

Most likely the switch that senses whether or not the door is closed is either out of adjustment, meaning when the door closes it doesn't physically make the switch contacts close, or the switch is defective. If you can physically find the switch you can "trick" it by holding it closed with a piece of tape. If that works then the switch is simply out of adjustment. If that doesn't work then you can short together the two wires going to the switch which simulates the closed internal contacts of the switch. If that works your switch has failed. If neither works then you may have a broken switch wire or solder joint where the switch inputs it's signal to a circuit board. If it is a bad circuit board you may spend the same amout of money replacing the board as you would buying a new microwave. Please be careful with theses test procedures and remember dealing with electricity can be a shocking experience! Good luck.

The door switches are the problem. Well, actually one of them is. when you open and close the door make sure the switches are actually being engaged. I have seen the plastic snaps that hold them broken and the switch just moves. Just replace all three switches and you will be fine.

You have a broken the door latch.Most people have the habit of slamming the door shut ( the same way some people hit the enter button on the computer ).With age the plastic becomes brittle and the slamming accelerates its demise. Now connected to this latch is a safety feature which shuts down the Microwave when the door is opened during cooking. So till you replace this latch the microwave will not work. Disconnect the microwave from the power outlet and remove the top cover ( 4 to 5 screws at the back ) , look near the bottom close to the DOOR OPEN button.You will see the rest of the latch with a spring attached to it.Do not attempt to glue the broken piece because the force exerted on the latch is very high and will not hold. You challenge is getting a replacement. Best would be to contact the seller or locate a authorized service center from where you might be able to procure it. It should cost you about 5$.

On the DMT2420, that's a bad bottom door switch, or possibly that switch's mount.
The service manual is here and the parts list is here. You can order Dacor parts by part number from the Pros here.

Check the door safety interlock switches.

Do you regularly shut the machine off by opening the door? Each event causes a small arc on the tiny contacts and will burn them. When they can no longer make contact, your microwave doesn't know if the door is open or closed. The machine must know the door is closed to turn in the magnatron (that thing that makes the heat).

Remove the cover and check the microw switches with a volt/omh meter.

I bet by now your microwave is no longer working....did the bottom or top "hook" finally break off? I found that mine had cracked and started coming loose and so when it closed it was no placing enough pressure on the internal safety switch that tells the oven the door is shut. I was able to use a sturdy plastic glue to solve the problem but finally after about 2 years of fixing it I can no longer get it to bond. Now, I'm looking for a new part. Who makes a product this expensive with plastic parts!!?!??!?!? So frustrating.

Just checked the GE website. Had the same problem with my 5 year old microwave. GE website says to close and open the door quickly three times. First time I did this it didn't work. Second time I closed the door with some significant force and reopened it more quickly. Worked. Unplugged the microwave, plugged it back in, still fine.

there is normally 2 swicth in the door actuater one may be def or sticking check them out
