Strange one here, The turntable in my Microwave wont turn off, even after timer runs out and micro shuts down when you open the door the turntable just sits there and spins without a care in the world

The cook relay on your control board is shorted, and the unit is cooking whenever you close the door.

When the magnetron overheats, its thermostat opens, shutting power down until the unit cools to a safe level, then power is restored.

I regularly repair these with my $54.95 service, which includes insured return shipping.

Details are here, or for full information and instructions, please e-mail me here at [email protected] and remind me of your full model number and symptoms.

I'd look for a defective relay or shorted triac on the control panel circuit board. Either could cause this problem.

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.

This indicates a bad door switch, or the keypad control board is not working properly.

There are one or two door switches that have become defective, they must be replaced for normal operation.

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.

Ok I have the same model and mine was doing the same thing. Apparently this model has a reputation of problems with the control board. I played with mine for hours and here's what finally worked: unplug the unit (or shut off the breaker--whichever's easier for you), take a dry cloth and wipe the door latches and control board clean of any residue. Then with the door still open, gently jiggle the control board by firmly grasping with your hand. Power up your unit again. This worked for me. The control board is really fussy and should be clean and free of any dust or residue. I notice this happens again when it gets dirty so I repeat the process and it's been working.....so far!!!

Probably a bad door switch. See this file.

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.

The power fuse open , if open replace it don't make jumper it b
cause fire .
the power transformer builtin fuse open/
The door micro switch open /need to replace.
