When i switch ON the microvave then the turntable moves clockwise and when again after a while it is again switched ON then it moves anticlockwise,so is this an abnormal situation or a normal one?

That could very well be an issue with the power supply. The chances on a relay failing on the DPDT switch side are very rare. Something is not telling the relay to close.

Does microvave button makes sound and when you start push button does the turn table moves.If yes for sound ,and no for turn table then you might have door switch which is either doesent latching or might broke.
open oven (be sure to discharge capacitors).
check its closing properly(the switch)
and use DMM to check resistance that it doesn't show OL

thanks
please rate my work

I just had the same problem with my ge spacemaker microwave model number JVM1490bd. I removed the grill on the top of the microwave with two screws on top. There is one screw that holds the front touch pad on, remove the screw and lift up to remove. The damper assembly is on the upper left, my door was sticking and didn't make the limit switch. I moved the door back and forth making the switch a couple times and that solved the problem.

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.

sounds like the unit has suffered a supply problem within its circuits power pass section it will need to go to a repair shop most are listed in your local phone book. although a short of this kind will no be cheap and depending on the price you paid for it i would be thinking about replacing it.

Possibly the light bulb has blown, which has blown on a track on the board which has taken out the turntable motor and the fan. Also, there could be a problem with the door switch.

This is usually caused by either a bad door switch or a loose door switch mount, which are pretty simple problems to fix.

Door switch or mount trouble is usually 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. This tab can be hard to see, since it is under the bottom edge of the switch.

If the switch mount is broken, it's usually more economical and safer to add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.

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 find helpful exploded view diagrams and order parts by entering your full model number here.

There should 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.



At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

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

While a microwave should never be left running unattended under any circumstances (as your owner's manual will tell you) it's even more important when one is exhibiting a failure or any odd behavior. So play it safe and stay with it while it's running!

You'll be loooking for part # 3517203600. Should be about a 10 inch tray

Many thanks to e3enigma above! I removed the synch motor under the turntable; all other microwave functions work fine and the grinding noise is gone, hooray! A trip to the appliance parts store tomorrow for a replacement synchronous motor and all should be well. Thanks again!
