    My microwave is doing the same thing, you think your food is heating up, but it is not. The only "bad" thing I can think of that happens to it is that if we run anything at the same time it blows the breaker. Could this happening many times have finally "blown" something in the microwave?

If the diode is good (not shorted) then I would suspect the magnetron.

Here are some tests that might help:

When I turn on my microwave. It sometimes shuts power off. The lights will go off and it will not run. I can unplug and plug it back in after a minute or two and it will work fine.


Sounds like the internal cooling fan may be stuck or defective. This will cause the micro to overheat which intern trips an internal heat safety. Once it cools down it will try to start again and repeat the same problem. Cooling fan is usually near the back behind the control panel.

Why does my microwave keep running/heating until I open the door? what can i do about it?


Sounds like a problem with the control panel. Further diagnostic testing would be required, however, as there can be other causes.

I need to reset my Kenmore Elite dishwasher but i don't know how.


Hello,

follow the below instructions:

Unlock your Kenmore dishwasher control panel by pressing and holding the "Heated Dry" button for four seconds.

Press a series of four buttons in quick succession. Press "Heated Dry," "Normal Wash," "Heated Dry" and "Normal Wash" to instruct your Kenmore dishwasher to run a short diagnostic test

Wait for two minutes while your Kenmore dishwasher runs its diagnostic test.

Press the "Cancel/Drain" button once your dishwasher has completed its diagnostic test. This should reset your dishwasher control panel and stop the "Clean" light from blinking repeatedly.
Good luck.

Doesnt heat up


in a microwave, there is no heating element. There are microwaves that heat up the water molecules, they make them spin fast and that's what heats things up. Running it with nothing in it, you really can tell if it's not working by that test either, again, nothing to heat up. I would put in a cup of water, set on high for 3 minutes and it should boil, if not, get a new one for the price, why mess around?

Never run the microwave without a load (something to heat)!!! That kills the microwave generating parts.

Sounds like a 'thermal' protect switch is activating after running. Make sure that (if the unit is mounted in a cabinet) that there is sufficient space around the unit for proper air flow and that nothing is blocking the vents. Try setting it on a counter top and heat something. If it works properly and doesn't shut off, the venting space is the problem. You may have to have the cabinet that it sits in redesigned for more clearance.

Our Jenn-Aire Model JMV8196AAS Microwave is not heating anything.



If it is working but not heating, then test the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.If turntable is not running check also the door switch.

The diodeand capacitors can be tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, evenif power is off.Capacitors can get discharged by shorting their two contacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.



All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts.

You can also order from MicrowaveSvc , they also provide parts.
