• ** REMEMBER! **The microwave can still shock you even unplugged!!

    ALWAYS discharge the high-voltage capacitor first if you even think your hands will come close to any HIGH VOLTAGE components.

    Jeff mentions this: Anything in the high voltage ( magnetron, capacitor, diode, wires to and from ):
    ...Use a metal ( not the shiny chrome type ) screw driver with a insulated handle to short across ( touch both at the same time ) the terminals of the high voltage capacitor to discharge it.

FIXED SMH1611W Samsung OTR Microwave - night light

So our OTR Samsung microwave's night light wont shut off. or even cycle through the high,low setting,( the one under the microwave)
I had to replace the bulb because it was burnt out,and i noticed that the light wont turn off,,not too sure if its a loose wire, ( due to the fact we have just moved our house to our new property and maybe with the move it could've loosened somthing).
I was gonna try open it up but someone recommended me against this.
Could just keep the bulb screwed in etc,, but id like to see if i can fix it.
Any help would be appreciated,thanks :)
Did it work correctly before it burned out? Is this the bulb you replaced?
Light Bulb 4713-001013

If the light bulb is good this is the part you need: Assy pcb main DE92-02434A
As far as i can recall,yes it was working before it burned out.With the new bulb as soon as its screwed in it comes on, but the "on, high,low" button has no effect. so to turn off the light u just unscrew the bulb. All the other functions on the microwave work no problem.

HOw easy is it to replace the part i need?
It's easy to replace. Just unplug the machine and remove the top grill then the screw that hold the control panel. Remove the board but leave all the wires connected and let it hang there. Install the new board the wires one at a time.
Now does the microwave need to be taken down or can the top grill be removed with it still mounted to the wall?

(sorry for more questions )
We welcome more questions. Ask as many as you want. The OTR microwaves are designed so most repairs can be done without taking it down. The door switches, TCOs, main fuse, and control panel can all be checked and replaced without taking it down. Sometimes it's easier to take it down if the problem can't be easily found.
