[RE-wrenches] SW repair

[Brian Mehalic]

Howdy-
Have a friend with stacked Trace SWs.  The fan on one is running nearly
continuously, so two questions:

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)?

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?

Thanks!
