This is especially true for any device where  malfunction such as this may cause a fire.  A stove turning on by itself is as major a risk as i can imagine, as I think about the number of times a stove has been used to hold a pizza box or other flammable items are placed on or near it.

Even when that 20-year old TV finally gives up the ghost, they my blame you and want the new 60" flat-screen model, please.

> 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.
