Kristopher,
Ray's advice is sound, and I'll add: that 14 year old inverter is likely
to last forever, and that's not a reason to keep using it. It's almost
certainly the crude waveform that's causing the issues.
If range replacement remains the only option, talk with Peerless-Premier
(www.premierrange.com). As of my last contact with them a few years ago,
they still make unadvertised models with circuit boards that were
designed for original Trace mod-square inverters and have no glow bars
for the oven. Our family home has a decent Pro series (stainless front
with sealed burners) with electric igniters and no glow bar.
