Sounds like ovens have gotten more complicated over the years. As soon
as I read "control board" and modified sine wave, I cringe. The good old
DR inverters worked great, I even ran my own shop on one for several
years back in the 90s. I for the most part quit selling them though, as
even though most equipment worked on the mod sine, we started noticing
premature failures. I would attribute this to the extra heat generated
by all the extra harmonic distortion. Sorry I can't recommend an oven;
they probably would be better going to something older form Craig's list
with no AC connection at all.

Hi Wrenches,
I have a client that has blown out 2 control boards on their oven in
the last few months. The appliance is a Whirlpool Model WFG515S0EW0
powered by a Xantrex DR1512. Since this is an off-grid home, i
recommended that they get an LP stove with no oven glow bar and this
was the unit that the appliance company supplied.
Has anyone seen this before (i am assuming incompatibility of the
circuitry with the modified sine wave output)?
Can you recommend another model that has been tried and true
(preferably Whirlpool)?
Thanks tons,
Kris
