Well the relay to energise the magentron is stuck on closed. You have main board problem. First check that board, the microcontroller is responsible for the relay via a switching transistor of FET. You have a shorted FET/TRN as well. Can't believe the tech did not check that. Thanks

SOURCE: Samsung Microwave model # SMH7178STD just stopped working.

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.

If you or a friend decide to look into it, we have critical information on safety, disassembly and door switches at our site, linked here on Fixya: http://tinyurl.com/yzjozk

UPDATE

The -SE-error is a shorted keypad.

If you would like to have us do this for you, we do that for $39.95 plus part costs.

Please feel free to contact me directly if you need more help.

SOURCE: Door handle broke off

Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the previously hidden screws you need to remove.

Or you can watch a YouTube video (not a video I made) here that demonstrates how it's done.

You can get Samsung parts here.

This is due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.

If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.

It may also need a new high-voltage diode and stirrer, and the cavity may be affected.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

You can order Samsung parts here.

You can find your nearest Samsung-authorized service center here.

To find out if yours was recalled, please call Samsung's Service Division at 800-932-3837.

SOURCE: SAMSUNG MICROWAVE, MODEL SMH9187ST, WHEN NOT

Hi dschema,

You have a door switch issue. There are three behind the panel. If you can lift and hold the door and it starts one of them is bad for sure. You would be better off replacing all three or have a repair man replace them because a microwave can hold 3000v even unplugged.

Hope it helps.

Thank you for using FixYa.

Why does my samsung MW725WB starts up on its own


Try putting a cup of water in the microwave to see if it is really heating, or if it is just making noise. If it is really heating on it's own whenever the door is closed, then you have a stuck relay on the control board, and you probably have to replace the control board. If it's just "making noise" (running but not heating), then it is probably a bad door switch.

My microwave GE model # JVM1440WH04 spacemaker has no heat coming out of it. My husband heated microwave lasagna in it last, everything works except for the heat, any solutions?


Push the microwave door tightly closed. The computer will not start cooking until the door is closed for safety reasons. Some models of microwave will give a warning on the screen if the door is open.
2

Ensure you have programmed a heat setting, entered a cooking time and pressed the "Start" button on the microwave's keypad. Check that the microwave is not set to "Defrost" mode.
3

Unplug the microwave and wait for one minute. This measure will reset the microwave's internal computer if it has frozen or scrambled. Plug the microwave back in and try again.
4

Ensure the keypad lock mode is inactive. Most microwave ovens have a lockout feature that prevents children from starting the microwave while unsupervised. Lockout mode is usually deactivated by holding down the button that bears a padlock symbol

did it come into contact with water at anytime, if yes than this is probably the reason ask an electrician to come and have a check or if it is working fine you can continue using but make sure that no liquid will spill over inside

Keypad Problems


Sometimes a keypad may not work because the door switches are faulty. When the door switches are working correctly it will allow the keypad to operate. They tell the microwave that the door is closed and the unit is dafe to use.

Many models have 3 door switches, it's wise to get all 3 replaced at once.
