I would suspect a door switch is defective or its mount is loose, misaligned, or broken.

SOURCE: Microwave does not heat

Just had the same experience with the identical model. Removed the cover (a challenge because of the security screws), revealing valuable troubleshooting directions intended for an experienced technician. However, I think the info is well within the reach of a typical DIY person, does not require any dangerous power-on conditions. However, make sure that you discharge the HV capacitor before trouble shooting. In my case, it appears that the HV diode is open, have ordered a replacement on the internet for $3.18, easy to replace. Hope it works. Good luck.

SOURCE: 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.

SOURCE: Microwave won't heat, and turntable doesn't turn

All the parts you mention are very inexpensive, but yours does not have a triac.

It could be the cook relay, but it's more likely to be a switch.

Looking at the schematic, it's probably a bad primary interlock (upper door switch) or maybe its mount is bad.

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

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

There may also be a "mini-manual" hidden inside the unit behind the control panel or elsewhere, 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.

GE Model # JVM7195SFSS microwave.


Check the internal ceramic fuse on the circuit board. Sometimes one section will work while another won't. I'm not sure if this model has a rear mounted thermal fuse, but the models with the inline thermal fuse will cause a similar issue.

GE Spacemaker XL - fan stopped working, light will come on and timer will count down.


either the magnatron fried , or the fuse fried... either way the microwve has to be taken down and opened up.
If you have the serial number , GE will send you a replacement magnatron (but will not service the unit for you).
contact GE and they will take care of you... the magnatrons are warranted for like 10 years....

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.

Are there any recalls on GE microwave JVM1540DN1ww Thanks, ssi96@aol.com


There are no recalls on GE over the range microwave JVM1540DN1WW but there SHOULD BE! Mine lasted only a year and a half and then started running and heating with the door open. Shortly after that it stopped heating at all. The light and fan works, and the keyboard lights up but the turntable doesn't turn anymore (yes I made sure the turntable was turned on), and it doesn't heat. It will count down like it's heating but it doesn't heat. Changing the door switches didn't work. Husband thinks it is the magnetron which is expensive to fix. I won't ever buy another GE microwave period! Check the web and you will see all the similar complaints. I just searched online and for a lesser price than I paid for the GE, Samsung sells one that has the one year warranty but also has a 10 year warranty on the magnetron.

No turntable, no heat. Light, vent fan and keypad all work...


That would be a problem with your primary interlock switch or its mount.

NOTE: 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.

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.
