No matter what happens, be sure to complain to the manufacturer and ask 
for an RFI kit to be installed.  They may have one already...

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.

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.
