thread, but I had similar problems with SW inverters back in the
day, that were fixed with a 50 mF cap. Reread that whole throead
as there were definitely potential problems associated with that
fix, but we found it worked fine, and never had any other issues.

<div>I talked to Magnum yesterday and they said there have been no

<div>Except better control of the search mode, around serial
number 350.</div>

<div>This doesn't seem to jive with what a few others have said or
my experience, but I guess that leaves no where to go with it.</div>

<div>I also asked about upgrading it, and yes cheaper to buy a new

I can't answer your question, but only relate that
I had a similar experience.<br>
<br>
An early Magnum MS4448AE would not reliably start
and run a modern hydronic boiler in an off grid
home. I had opened a case with Magnum tech
support, but the frustrated HVAC contractor pulled
the unit and installed a different brand of boiler
and the problem disappeared.<span
class="Apple-converted-space"> </span><br>
<br>
In my own home my MS4024AE has nothing it won't
run, and it's a newer unit. But whether that's
coincidental or the result of an inverter firmware
or hardware upgrade, I can't say. Maybe Gary
Baxter can?<br>
