Hi Dan,
I reached out to you directly after hearing about your issue. I too have this
problem with my Samsung gas stove. For me, the issue is the worst with as
little as 15W on 40M and 50W on 17 and 20 meters.
The first time I came downstairs saw that the oven was on and already heated to
400+ degrees, I knew immediately what happened.
My oven model: NX58M6630SG
If you find a solution on your own that really works, I would love to know the
exact list of parts and methodology you used. If you get the ‘ear’ of someone
at Samsung, PLEASE pass the contact information to me directly off list.
Thanks and 73,
K5RHD
