Please do not  open the stove or do anything internal. 
 First off this is critical to safety. The RFI can do a lot more than just make noise  or flash lights.

I have a recent case in the ARRL RFI database when a Hams neighbor was having his Samsung Gas stove turn on the oven  in the middle of the night.
This happened to coincided with the Ham operating a 20 meters CW on a schedule.
You do not want to have any liability for going inside off this stove.. 
Call Samsung ,,
Cal me at the number below and we can talk about this.

Here is the model number of the stove that would turn on based on RF.... Samsung Gas Range, Model NX58H5600SS/AA
I also have several other cases of RFI ingress to the same model number.

In the local case above Samsung replaced the stove..
Please give me a call.

Subject: [RFI] Oven RFI help needed

We recently purchased a new spiffy oven with lots of bells and whistles. There is a great touch pad to control all the nifty functions and it works well. The oven does not interfere with my station BUT....
When I transmit at low power the oven beeps (the same beeps as the touch pad). If I run high power it becomes hysterical and sometimes locks up requiring a power down and restart. I have pulled the stove out and installed several clamp on toroids on the power cord to no effect. I have traced the wiring and I think it is on a dedicated circuit that runs back to the breaker box.

Interestingly, it has a “lock” function that disables the key pad and locks the over door shut. You can not use the oven with this engaged. But, I don’t affect the oven with the lock function engaged. I can live with this but can envision my lovely wife wanting to use the oven while I’m banging away in a pileup or contest. So, domestic bliss is the driver for my query.

It is a Samsung gas oven. If any one has any experience or ideas I would be very interested. I am loath at this point to pull the back off to put toroids or bypass caps in.
