Question about Dacor DMT2420SS Microwave Oven
This morning, our Dacor m/w oven stopped working - panel was still on and counting down seconds as normal, but no m/w sound or platform turning. After tinkering with it, I realized that the m/w sound and platform returned to normal when I apply a slight amount of pressure to the dooor opening button (not enough to open the door). Seems like there is a contact behind that button that is a bit off.
How can I fix this myself? I removed the door button, cleaned and inspect it but I cannot seem to see anything I can do barring taking the whole thing apart. Any help is much appreciated
That would be a defective secondary interlock (lower door switch) or its mount.
Door switch or mount trouble is usually 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 is under the bottom edge of the switch.
We have the service manual for this model and have uploaded it to our site here to help you.
You will need the free Acrobat Reader to view or print it in case you don't have it.
If you only need a switch, you can order a universal type here for $5 postpaid.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
