[RE-wrenches] Issue with DR1512 and oven

Tue Sep 20 10:11:36 PDT 2016

I have a copy of the official service and diagnostics manual for DR series. It's a 1.5" thick binder full of fold out legal pages, addendums, etc. Not the easiest thing to scan. Is there something particular you are looking for?

We are looking for a schematic for the DR series inverter. Does anyone have one they could send me?

Thank you,

Drake

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<http://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.

Thanks Ray,

This is a circa 2002 inverter.  I may just tell them to go to a pilot light stove model (hate to waste gas, ya know).

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
