Question about Emerson MW8108P Microwave Oven

1 Answer

Microwave runs on its own

After the timer has hit "0" and the buzzer goes off, the microwave turntable continues to spin. When you open the door a fan goes off but the turntable continues to spin. When you close the door the motor (seemingly a fan)kicks back on - whether you've entered a cook time on the clock or not. It seems you can't turn this thing off. Thanks for your help.

This is usually caused by either a bad door switch, a loose door switch mount, or occasionally a problem on the control panel.

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.

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. Other times, 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.

One test that sometimes helps is to gently lift up on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

If you or 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:.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

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.

Turntable goes around when the door is open and the microwave is off.


Do not run the microwave with the door open. You will be cooked. Sooner or later, if there are enough microwave ovens, (and there are), everything that can go wrong with them will, eventually. There are several interlocking safety systems built into every microwave so that they won't work with the door open. Yours may have failed. I've never come across one, but that doesn't mean it can't happen.
It may only have a fault making the fan and turntable operate, which can sound like it's working with the door open. Either way, get it checked or get a new one.
This assumes that the microwave isn't actually supposed to do what it is doing under normal conditions or current programming. Refer to manual/instructions if unsure.:::Spiceweasel.au

Microwave on its way out?


This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

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.

My microwave continues to run, (turntable and exhaust), when the door is opened.


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.

Turntable Problem


If it jumps or moves just a little when you open the door, that is normal. It it actually runs, then you have a problem. Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP button) is the primary cause of door switch failure. You can visit my Web site at _ or e-mail at _ if you'd like more in information on diagnosing and repairing this problem.
