Brian, </FONT></SPAN></DIV>

<DIV><SPAN class=123183119-05122013><FONT face=Arial color=#0000ff size=2>In my
experience this is a relatively common failure. Fans will burn out after a few
years of continual run and yes, they are a pain to replace but can be done, the
fan can be purchased from electronics shops. </FONT></SPAN></DIV>

<DIV><SPAN class=123183119-05122013><FONT face=Arial color=#0000ff

hassle. </FONT></SPAN></DIV>

<DIV><SPAN class=123183119-05122013><FONT face=Arial color=#0000ff size=2>I have
in the past with success rigged an external fan to run when AC input
detected (ie generator on) as fan is mostly used during charge unless the
inverter is working hard. Ugly but functional. </FONT></SPAN></DIV>

<DIV dir=ltr>Howdy-
<DIV>Have a friend with stacked Trace SWs. The fan on one is running
nearly continuously, so two questions:</DIV>
<DIV><BR></DIV>
<DIV>Anything in the settings that could cause this (it isn't related to the
load, which is usually low and evenly split between the two 120 legs)?</DIV>
<DIV><BR></DIV>
<DIV>How about repairs? The concern is it will fail...I've never changed
out any internal parts on SWs, and a few posts on the internet made it sound
like the fan is a pain in the butt. Any reputable repair shops in the
Southeast or east coast?</DIV>
<DIV><BR></DIV>
<DIV>Thanks!<BR clear=all>
