Follow this steps and fix it. God bless you

  1. Inspect the power cordUnplug the power cord and check for voltage at the outlet. Also inspect for damage, shorts, or burn marks that can be a possible safety hazard.
  2. Bad door switchIf your microwave does not work at all and you know everything is plugged in properly and the outlet is functioning, then also check the door hooks and the door release button. Using a volt-ohm meter on RX1, check your terminals. When your microwave door is closed you should have a reading of zero. Once the door is open the reading should change to infinity. If these readings do not match up, replacement of the door switch is necessary.
  3. Blown fusesTo determine if your fuse has blown out, which may attribute to your microwave not running, you need to pull the fuse out using a pair of fuse pullers. Lay it down and using a volt-ohm meter on RX1, check both ends of the fuse in question. If you do not get a reading of zero, then you will need to replace the fuse.
  4. Bad fan motorLocate the fan and remove the leads. Again using the volt-ohm meter on RX1, check the terminals. If an infinity reading is displayed, it means that the fan has gone bad and requires replacement.

Sounds like the problem is in the high voltage. Most common would be magnatron, capacitor and diode. For safety reasons this should be checked by a professional. Look in your owners manual because some high voltage parts have a longer warranty than 1 yr.

SOURCE: How do i replace the keypad of GE Profile over the range microwave

We have *critical* safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting. It will help you test the keypad with your meter.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

If you'd rather have us fix it for you, we do that for $39.95 plus parts.

DISCONNECTING THE KEYPAD

1. Be sure the oven is disconnected from the power line while you are taking it apart.

2. The keypad connection is the green or blue translucent plastic strip that plugs into a connector near the edge of the board.

3. There are two tiny tabs (one on each side) of the connector that you can gently pull up on to unlock the connector.

4. Then the keypad strip will lift out. Clean both sides of the end of the strip with alcohol-based cleaner if you like, but do not use ammonia-based cleaner. Dry the end of the strip. (A pencil eraser is better and safer).

5. Put the keypad strip back in, making sure both sides are down fully.

6. While holding the strip down, push the connector back down to lock it.

7. Try the keys again with the door closed.

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: GE Profile Microwave - JVM2070SK02 - when turning

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week.

At our Web site, you can get details of our service, plus we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

Sometimes this will also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

Feel free to contact me directly (and please remind me of your full model number) for more information & help.

If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if contact is not through the microwave will not work.

Now keeping clear of the microwave, switch on, use a cup of water inside to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type. In this case it seems that the program controller board has errors specially if the oven heats and shuts off. remove the board, clean and reset.
If there is heating without any issues, you can use the microwave safely

Hi,

It sounds like one of the door micro switches is bad. There are three micro switches typically. A primary interlock, a secondary interlock and a monitor switch. It is most likely the primary or secondary interlock switch. You may need to take your switches to a professional appliance shop to determine which one is bad.


Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Unplug the thing, open it up, and carefully take off the pad button controls and anything else with wrong behavior, and wash those things out with dishsoap and deionized water.  It seems like a pad switch has saltwater or sugar in it, or crumbs pressing on it.  The door and main switch often need cleaning out also, though compressed air or cotton swabs (no excess water) will be fine.  Then put it back together, plug it in, and try it.

Turntable does not turn and fan won't exhaust


The second problem is probably defective door switches, or it may be a problem with the control panel, which we repair nationwide for only $32.50. On my Web site, I have info on safety, disassembly, and diagnosing and replacing door switches: http://tinyurl.com/yzjozk Running it empty has damaged the magnetron. It will work for a while, but it will eventually have to be replaced. A good parts source is here: http://tinyurl.com/gv383
