Question about Dacor DMT2420SS Microwave Oven

Dacor Microwave - Light/Turntable turn on if we close the door

If we close the door on the microwave, the light immediately turns on and the turntable starts rotating. It is not heating. We cannot stop it with any button. We unplugged it for several minutes and plugged it back in and it immediately turned on again.

    the model number is DMT2420S.



    Not sure if I made it clear from the description, but as long as this thing is plugged in, if I close the front door, the turntable and light immediately start - but no heating takes place. Need to keep it unplugged or else it would run all day. Thank you.

    It's probably a problem with a door switch or mount or a shorted switch on the controller.

    These are pretty simple fixes, and I probably have the service manual, but I would need your model number.

Sorry but I meant to also ask if it will still heat the food when you microwave with it.

I'll assume it does, but if not, please write back and let me know.

This would be a shorted relay RY1 on the control board.

There are two options for this model:

- You can order our exclusive modified control unit with our proprietary upgrades for $115, then if you return your defective control unit in repairable, good cosmetic condition, we'll give you a core refund of $30.

For details, see: http://www.microwavedisplay.com/exchange.htm

- Or we can repair your existing control unit for $39.95 in about a week with a one year guarantee.


Feel free to contact me directly (and please remind me of your full model number) for more information & help.

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

Turntable not turn, light on, no heating


It would have helped if you mentioned your brand and model, but it's probably a bad door switch or door switch mount.

If it's a Sharp or Dacor brand, it's probably the bottom door switch.

My door switch text file gives you help and links for such problems. It's here.

Light and display work but not unit or turntable


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.

Chances are you have a bad bottom door switch or a misaligned bottom door switch mount.

We have the service manual for this model and have uploaded it for you here. The separate parts list (if needed) is here.

Also see our file on door switches here.

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

Turntable won't stop


Sounds like a door switch problem or stuck relay contacts on the control PCB. Do the light and fan run too or just the T/T??

Dacor dcm24s.light, fan, and control panel work but turntable and heat do not


Most likely the bottom door switch. Dacor units are built by Sharp and that switch is a very common problem. You'd either need to check the switch with an ohm meter or remove the cover of the switch to see if it's burned inside.

Microwave seems to turn on when door latch is opened


What's happening is you are activating one door switch a little before the other, and that is causing your light, fan, and turntable to come on. The plastic parts are not perfectly rigid, so they flex a little when you press the button, and that causes the lag to be more apparent. Even if you press the door open faster and look really close, you may notice the light, fan, and turntable coming on for a split second. That's perfectly normal. The relay on the control board must also be turned on before it will actually be cooking.
