Piezo sparking stove [RE-wrenches]

Kurt,

I had a similar problem with our Peerless and an inverter. I wanted 
to put a dedicated 24 V inverter on it so we didn't have to pull the 
SW out of sleep to start the burners. Jay Peltz got me a cheap little 
inverter (maybe he remembers the brand).

When I plugged the stove into the inverter, all four burners sparked, 
even though no one was touching the stove knobs and they were all 
off. Weird.

I never got a good answer as to why that happened, and we returned 
the inverter. I'm all ears for an explanation, and for 
recommendations of a small 24 V inverter that won't do that.
