SOURCE: Fan runs when door is closed - no heat

This is normally 1 of the interlock door micro-switches not working.

SOURCE: Microwave turntable won't stop running

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

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

First of all, it's under warranty. So I would contact Maytag for a free fix.

See http://maytag.com/support/service_parts.jsp

For an out of warranty reply:

SOURCE: Microwave will not turn off

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 (and/or push down) 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:.

You can probably find exploded views and order parts by entering your model number here at the Sears parts site.

There may also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

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

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

SOURCE: Sharp Carousel R-1481 Turntable

It may very well have have damaged the turntable motor.

The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

On many Sharp models, you have to cut the motor cover off with snips, then use a screw when reassembling it.


We have the service / repair manual for this model and have uploaded it to our site here to help you.

It will give you safety info, step by step help in disassembly, troubleshooting tips, and part numbers.

You will need the
free Acrobat Reader to view or print it in case you don't have it already.

The best place to order parts for this brand is Encompass (formerly Tritronics). Or you can call them toll-free at 866-779-5835.

Be sure if you cook an egg that you puncture the shell first so it can breathe.

Samsung microwave turns on when open door


The switch assembly is somehow staying "closed" satisfying the interlock and enabling it to run.
Disassemble the unit, beware specially of the high voltage capacitor, if you aren't comfortable or competent, buy a new microwave. If you are mechanically inclined, disassemble the unit until the switch assembly is accessible; it will have the door latch attached to it.
The switch is either broken or something? exogenous is keeping it closed. It may have come loose due to the door slamming?.
It's a simple fix. I am certainl you will be successful.

Mbbs 01 thermador micro oven: timer counts down, lights go on, but no heat, no fan and turntable does not turn. is it a fuse?


Key clue is table does not move---All microwaves with a table have a lever switch that is engaged when door closes--only can get at from inside the unit----it prevents the unit from operation if door not closed.

What happens from closing door a lot is the switch with a lever arm can come loose or even if snapped into a plastic holder break out of the holder.

IF this it is not too expensive a repair.

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??

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.
