Question about Samsung Microwave Ovens

Samsung microwave turns on when open door

Everytime we open the door the microwave turns on. It sounds like it does when cooking with door closed. It turns off when we close the door. We can heat food when door is closed and touch pad works and turntable spins. But it's also turning on when we open the door.

    Thank you Eustacio. Where does the switch assembly and door latch reside? On the door itself? Or do you mean the front face of the microwave behind the door, behind the side where the touch pad and control board are? Thanks again.

The switch assembly is somehow staying "closed" satisfying the interlock and enabling it to run.
Disassemble the unit, beware specially of the high voltage capacitor, if you aren't comfortable or competent, buy a new microwave. If you are mechanically inclined, disassemble the unit until the switch assembly is accessible; it will have the door latch attached to it.
The switch is either broken or something? exogenous is keeping it closed. It may have come loose due to the door slamming?.
It's a simple fix. I am certainl you will be successful.

    Hello. Thank you for your detailed reply. My husband is a union trained electrician with a commercial license. Will that be enough experience to handle such a repair? Or would it require additional mechanical engineering knowledge?

RE: Samsung microwave SMH7187STG mfg'd 5/08. I heated cup of tea 2 min.Then I closed micro's door & micro emitted a continuous electrical buzzing sound.I opened door & buzzing stopped.


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 pupista@gmail.com and remind me of your full model number and symptoms.

Kenmore elite microwave 721.80833 stops cooking intermittently


Check the door switches if one is bad it may think the door is being opened and stop the unit from running. If it is from a bad connection it will get worse as it gets hotter while running.

If I stop regular microwave cooking to check the progress, and then push start to continue, it does not cook. It just stops working. I have video of bacon taking 15 minutes to cook, because it stopped. ...


Sounds like door switch issues. Thinking the only thing you did was open and close the door, not change programing or anything. If you have an issue with a door switch and it doesnt close right after opening and closing the door( when you stir), the unit thinks the door is open so it will not run. Once the bad connection cools down it contracts and reconnects and the unit will work again. Frequently you can find which switch is doing that if you just look at the switches and see if you have any browning inside of the plastic insulators over the wires that push onto the switch terminals. If the connecton is bad it will get hot that will brown the plastic protector

Model R-1460, when I shut the door it runs but doesn't heat up. What needs to be done to fix it?


Do you mean that when you close the door, the fan comes on? If so, it sounds like a bad door switch. Probably the secondary interlock switch.
This failure is caused by opening the door when the unit is in cook mode. On ALL microwaves, not just one or two brands.......
Be sure to push the stop button before opening the door to add or stir... Or wait for the cook cycle to end. (This is why microwaves have a two step function on the stop/clear button. Hit stop once to stop cook mode and twice to reset timer).
You should use an ohm meter to check all 3 switches. The switch can be either stuck 'closed' or physically closed but not 'making' electrically.

Our microwave/convecton turns itself off after about a minute


This is a problem in one of the damper-related components, most likely the switch, but it may also be the motor or the damper door.

The damper is a door inside that opens or closes depending on cooking mode. If the controller senses that the door is not in the right position, it will shut down the cook cycle.

Sharp models stop after 59 seconds.

See the attached sample photo for a typical damper assembly.

We have the applicable service manuals for these models and have uploaded it to our site here and here to help you. You will need the free Adobe Reader to view or print it.

If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Microwave turns on and counts down but won't heat up/cook


Ok just figured this out! It is a problem with the alignment on the lower door switch. I took the cabinet off and lifted up on the door switch slightly and voila! It works. You could probably fix this without taking it apart, just lift up on the door ever so slightly. I hope this works for you.
