Question about Samsung Microwave Ovens
Samsung SmH9 151S shows the letters SE on the panel. Have tried reseting the circuits and unplugging/replugging the appliance. What is it asking me to do?
That error means that the touch panel is sensing a button that is stuck down. The touch pad might have a short in it.

A microwave can be dead for many reasons.
It may be the fuse, which is usually located on the floor of the oven behind the control panel or between the door switches.
If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.
If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.
Then when it cools, it closes the circuit and allows power through again.
When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.
If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
If it goes dead or blows the breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.
If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.
You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.
If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.
We have critical safety & disassembly info (including a how-to video) at our site, linked here.
There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.
You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

SE error means you have a shorted keypad . If you couldn't find parts , then It will be cheaper to replace the unit or have new one .
good luck .

SOURCE: The letters "SE" is on
Hi, there are two possibilities. (1)keypad failure and (2) bad connection.
Obviously the easiest thing is to clean the connection. So first take the cover off. Behind the keypad is a circuit board. In addition to a few connections between the circuit board and other parts of the microwave, there is a ribbon connecting the keypad to the circuit board.
Loose the plastic on the connection, pull the ribbon out from the socket.then use a spirit to clean the exposed copper connections. Put every thing back to place then try it

i think your getting to much moisture in your microwave the exhaust fan is to small and can't handle it. once everything dries out you are able to rest it check with samsung.
