This sounds like either a bad door switch or possibly a latch head problem from taking the door apart......

SOURCE: Frigidaire microwave FMV156DBC turns on with door

SOURCE: frigidaire microwave plmv168cc1 makes humming noise when door closed

Chances are that the secondary (cook) relay on the control circuit board is shorted, meaning that the oven is actually cooking any time the door is closed.

You can test that by putting in a cup of water, shutting the door, and letting it go for about 30 seconds, then checking the water temperature.

This is dangerous, and can lead to a fire, so please unplug the oven until it is repaired.

The relay can be replaced for far less than the cost of a new control circuit board.

Samsung microwave turns on when open door


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.

Why microwave won't stop running unless door is open ?


Is it actually heating or just making noise and acting like it's heating? (put a cup of water inside and close the door.) IF it's actually heating, then you have a shorted relay on the main control board, and you will have to replace the board. IF it's just making noise like it's working, but it's not heating, then the problem is 1 of the door switches is not working right (it's either stuck open or stuck closed).

DOOR LATCH PROBLEM...HOLDING IT CLOSED AND TURNING IT ON WORKS AND HEATS. IS IT A DIY FIX PROBLEM? THANKS FOR THE HELP, DEBBIE


follow this steps and fix it. God bless you

  1. Open leverCheck your microwave lever to determine if it is damaged. If it is broken, simply replace the lever to get your microwave door fully functional again.
  2. Door springResponsible for keeping downward pressure on the door hook, the microwave door spring can begin to malfunction. If this part is broken and prevents you from opening your microwave door, replacement is necessary.
  3. Door latchOne reason your microwave door may not open properly is a broken door latch. Located inside the microwave, the door latch manipulates the door hook to keep the door closed for safety and top performance. If broken, the door could become stuck in the locked position.
  4. Door hookIf your microwave door will not release properly, the door hook could be damaged. Located inside the door, the door hook is made of plastic and prone to breakage with extended use or age. As this part is unable to be repaired, the only option is to replace it.
  5. Button or button springIf the microwave door will not open, it could be an internal failure of the button or button spring. If it is determined that either of these parts is the source, both are replaceable and it is recommended that they be installed at the same time.
  6. Handle actuatorIf the microwave door will not open the plastic handle actuator could be broken. Connected between the door button and the door latch assembly, this plastic part could become damaged and brittle over time, which makes breaking inevitable. If this occurs, replace the handle actuator to get your microwave fully functional again.

Sharp Insight Pro microwave drawer KB6024MS not working


The drawer often stops working when it is abruptly stopped while opening and forced closed or vice-versa. To fix, simply do the following:
1) Push the draw all the way closed
2) Push the "Setup" button repeatedly until the "Open/Close ...?" appears.
3) Hold the Start Button until the time reappears in the display.
4) Repeat steps 2 & 3 three more times
5) Unplug the Microwave for 30 minutes.
The drawer is now reset. The drawer will now open electronically (automatically) either by pushing the open button on the panel or by pulling the drawer handle slightly.

Microwave not heating


You need to replace the whole door latch with an original part.

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.

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.

Hi there in my microwave when i switch it on the rotator, fan and lamp gets switched on automatically. but magnetron doesnot get started untill i start the timer on the microwave. how can I stop rotatorm...


This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.
