Fan runs and turntable turns when door is opened

I just bought an RV with the exact same microwave and the exact same problem. The problem with mine is the switch that detects that the door is closed is not getting activated. The reason for this is is the finger at the top of the door is damaged as well as the plastic piece that the finger grabs onto when the door is closed. This causes the finger not to come into contact with the switch. To test this you can turn your microwave on and start it. open the door and using a small screwdriver, depress the micro switch you can see upper right side of the door opening. then press start again. your turntable will start turning and the microwave will make a louder noise as a fan will turn on. CAUTION! Release the button as soon as you see the turntable rotation as you will be receiving microwave energy due to the door being opened.

Mine did this too. Also, at times when I would shut the door, the whole keypad would go dark and the clock would have to be reset. There were also times when I would push Start and it would do nothing. I'd have to unplug it so it would reset itself.
I used a screwdriver and forced the door open. Mine is about 2 years old and it's now dead. Biggest piece of junk I've purchased in years. Really ticked me off, no more LG products for me. I had a Toshiba that lasted me 22 years and the only thing that went bad on it was the light stopped working and the fan cover fell off.

Check to make sure the Spindle that the plastic piece fits on is turning when the oven is on.
If the spindle turns, your problem is either the plastic wheel adapter is worn or not making proper contact with the spindle. You can replace th e adapter by going to Cuisinart.com.
If the Spindle is not turning, you can go to Cuisinart.com and find the nearest repair facility.

your door switch is mis-adjusted,furthermore the other safety switch on the door should have blown the power fuse in the unit,because by design for safety it produces a short circuit if door opens under operation,so if door was taken off and replaced it was not adjusted properly

Sounds like there is a stray piece of wire or other metal floating around inside the case. Remove the cover and any breakables in the microwave (the power cord is unplugged for this), turn it upside down over a table and shake it, pound the bottom, and shake it some more--likely the offending piece will drop out onto the table. If so, put it back together and whack it to see if that fixed the problem (cord plugged back in). This process can be repeated.

The turntable is a seperate intenty from the microwave itself, I would presume that the switch that turns off the turntable when the door is opened needs replacement.

sounds like there is a switch that is bad. you can go buy a new MW for about 200$ and in yours if there is a major problem then i would just go buy a new one but might be worth a repair man to come check it out


pleas do not poke around in the microwave as it carries a charge of 5000volts and can kill you even if not plugged in DON'T TOUCH THE WIRES WITH BRAIDS ON THE OUT SIDE if you must get inside of the unit

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.

It's probably a bad door switch or door switch mount.

all microwaves have 2 safety switches at least... but these are tied to a set of relays that turn it on, my bet is a sticking or stuck relay because you unplug it right and plug back in its not running?-relay ... if always runs driver transitors.
